Credits section +/// +/// ## About +/// This is a minimal state immediate mode graphical user interface toolkit +/// written in ANSI C and licensed under public domain. It was designed as a simple +/// embeddable user interface for application and does not have any dependencies, +/// a default renderbackend or OS window and input handling but instead provides a very modular +/// library approach by using simple input state for input and draw +/// commands describing primitive shapes as output. So instead of providing a +/// layered library that tries to abstract over a number of platform and +/// render backends it only focuses on the actual UI. +/// +/// ## Highlights +/// - Graphical user interface toolkit +/// - Single header library +/// - Written in C89 (a.k.a. ANSI C or ISO C90) +/// - Small codebase (~18kLOC) +/// - Focus on portability, efficiency and simplicity +/// - No dependencies (not even the standard library if not wanted) +/// - Fully skinnable and customizable +/// - Low memory footprint with total memory control if needed or wanted +/// - UTF-8 support +/// - No global or hidden state +/// - Customizable library modules (you can compile and use only what you need) +/// - Optional font baker and vertex buffer output +/// +/// ## Features +/// - Absolutely no platform dependent code +/// - Memory management control ranging from/to +/// - Ease of use by allocating everything from standard library +/// - Control every byte of memory inside the library +/// - Font handling control ranging from/to +/// - Use your own font implementation for everything +/// - Use this libraries internal font baking and handling API +/// - Drawing output control ranging from/to +/// - Simple shapes for more high level APIs which already have drawing capabilities +/// - Hardware accessible anti-aliased vertex buffer output +/// - Customizable colors and properties ranging from/to +/// - Simple changes to color by filling a simple color table +/// - Complete control with ability to use skinning to decorate widgets +/// - Bendable UI library with widget ranging from/to +/// - Basic widgets like buttons, checkboxes, slider, ... +/// - Advanced widget like abstract comboboxes, contextual menus,... +/// - Compile time configuration to only compile what you need +/// - Subset which can be used if you do not want to link or use the standard library +/// - Can be easily modified to only update on user input instead of frame updates +/// +/// ## Usage +/// This library is self contained in one single header file and can be used either +/// in header only mode or in implementation mode. The header only mode is used +/// by default when included and allows including this header in other headers +/// and does not contain the actual implementation.

+/// +/// The implementation mode requires to define the preprocessor macro +/// NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.: +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C +/// #define NK_IMPLEMENTATION +/// #include "nuklear.h" +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// Also optionally define the symbols listed in the section "OPTIONAL DEFINES" +/// below in header and implementation mode if you want to use additional functionality +/// or need more control over the library. +/// +/// !!! WARNING +/// Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions. +/// +/// ### Flags +/// Flag | Description +/// --------------------------------|------------------------------------------ +/// NK_PRIVATE | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation +/// NK_INCLUDE_FIXED_TYPES | If defined it will include header `` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself. +/// NK_INCLUDE_DEFAULT_ALLOCATOR | If defined it will include header `` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management. +/// NK_INCLUDE_STANDARD_IO | If defined it will include header `` and provide additional functions depending on file loading. +/// NK_INCLUDE_STANDARD_VARARGS | If defined it will include header and provide additional functions depending on file loading. +/// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,... +/// NK_INCLUDE_FONT_BAKING | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it. +/// NK_INCLUDE_DEFAULT_FONT | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font +/// NK_INCLUDE_COMMAND_USERDATA | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures. +/// NK_BUTTON_TRIGGER_ON_RELEASE | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released. +/// NK_ZERO_COMMAND_MEMORY | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame. +/// +/// !!! WARNING +/// The following flags will pull in the standard C library: +/// - NK_INCLUDE_DEFAULT_ALLOCATOR +/// - NK_INCLUDE_STANDARD_IO +/// - NK_INCLUDE_STANDARD_VARARGS +/// +/// !!! WARNING +/// The following flags if defined need to be defined for both header and implementation: +/// - NK_INCLUDE_FIXED_TYPES +/// - NK_INCLUDE_DEFAULT_ALLOCATOR +/// - NK_INCLUDE_STANDARD_VARARGS +/// - NK_INCLUDE_VERTEX_BUFFER_OUTPUT +/// - NK_INCLUDE_FONT_BAKING +/// - NK_INCLUDE_DEFAULT_FONT +/// - NK_INCLUDE_STANDARD_VARARGS +/// - NK_INCLUDE_COMMAND_USERDATA +/// +/// ### Constants +/// Define | Description +/// --------------------------------|--------------------------------------- +/// NK_BUFFER_DEFAULT_INITIAL_SIZE | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it. +/// NK_MAX_NUMBER_BUFFER | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient. +/// NK_INPUT_MAX | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient. +/// +/// !!! WARNING +/// The following constants if defined need to be defined for both header and implementation: +/// - NK_MAX_NUMBER_BUFFER +/// - NK_BUFFER_DEFAULT_INITIAL_SIZE +/// - NK_INPUT_MAX +/// +/// ### Dependencies +/// Function | Description +/// ------------|--------------------------------------------------------------- +/// NK_ASSERT | If you don't define this, nuklear will use with assert(). +/// NK_MEMSET | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version. +/// NK_MEMCPY | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version. +/// NK_SQRT | You can define this to 'sqrt' or your own sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version. +/// NK_SIN | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation. +/// NK_COS | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation. +/// NK_STRTOD | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!). +/// NK_DTOA | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!). +/// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe. +/// +/// !!!

This includes at least +/// filled and stroked rectangles, circles, text, lines, triangles and scissors. +/// As soon as this criterion is met you can iterate over each draw command +/// and execute each draw command in a interpreter like fashion: +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// const struct nk_command *cmd = 0; +/// nk_foreach(cmd, &ctx) { +/// switch (cmd->type) { +/// case NK_COMMAND_LINE: +/// your_draw_line_function(...) +/// break; +/// case NK_COMMAND_RECT +/// your_draw_rect_function(...) +/// break; +/// case //...: +/// //[...] +/// } +/// } +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// In program flow context draw commands need to be executed after input has been +/// gathered and the complete UI with windows and their contained widgets have +/// been executed and before calling `nk_clear` which frees all previously +/// allocated draw commands. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// struct nk_context ctx; +/// nk_init_xxx(&ctx, ...); +/// while (1) { +/// Event evt; +/// nk_input_begin(&ctx); +/// while (GetEvent(&evt)) { +/// if (evt.type == MOUSE_MOVE) +/// nk_input_motion(&ctx, evt.motion.x, evt.motion.y); +/// else if (evt.type == [...]) { +/// [...] +/// } +/// } +/// nk_input_end(&ctx); +/// // +/// // [...] +/// // +/// const struct nk_command *cmd = 0; +/// nk_foreach(cmd, &ctx) { +/// switch (cmd->type) { +/// case NK_COMMAND_LINE: +/// your_draw_line_function(...) +/// break; +/// case NK_COMMAND_RECT +/// your_draw_rect_function(...) +/// break; +/// case ...: +/// // [...] +/// } +/// nk_clear(&ctx); +/// } +/// nk_free(&ctx); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// You probably noticed that you have to draw all of the UI each frame which is +/// quite wasteful. While the actual UI updating loop is quite fast rendering +/// without actually needing it is not. So there are multiple things you could do. +/// +/// First is only update on input. This of course is only an option if your +/// application only depends on the UI and does not require any outside calculations. +/// If you actually only update on input make sure to update the UI two times each +/// frame and call `nk_clear` directly after the first pass and only draw in +/// the second pass. In addition it is recommended to also add additional timers +/// to make sure the UI is not drawn more than a fixed number of frames per second. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// struct nk_context ctx; +/// nk_init_xxx(&ctx, ...); +/// while (1) { +/// // [...wait for input ] +/// // [...do two UI passes ...] +/// do_ui(...) +/// nk_clear(&ctx); +/// do_ui(...) +/// // +/// // draw +/// const struct nk_command *cmd = 0; +/// nk_foreach(cmd, &ctx) { +/// switch (cmd->type) { +/// case NK_COMMAND_LINE: +/// your_draw_line_function(...) +/// break; +/// case NK_COMMAND_RECT +/// your_draw_rect_function(...) +/// break; +/// case ...: +/// //[...] +/// } +/// nk_clear(&ctx); +/// } +/// nk_free(&ctx); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// The second probably more applicable trick is to only draw if anything changed. +/// It is not really useful for applications with continuous draw loop but +/// quite useful for desktop applications. To actually get nuklear to only +/// draw on changes you first have to define `NK_ZERO_COMMAND_MEMORY` and +/// allocate a memory buffer that will store each unique drawing output. +/// After each frame you compare the draw command memory inside the library +/// with your allocated buffer by memcmp. If memcmp detects differences +/// you have to copy the command buffer into the allocated buffer +/// and then draw like usual (this example uses fixed memory but you could +/// use dynamically allocated memory). +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// //[... other defines ...] +/// #define NK_ZERO_COMMAND_MEMORY +/// #include "nuklear.h" +/// // +/// // setup context +/// struct nk_context ctx; +/// void *last = calloc(1,64*1024); +/// void *buf = calloc(1,64*1024); +/// nk_init_fixed(&ctx, buf, 64*1024); +/// // +/// // loop +/// while (1) { +/// // [...input...] +/// // [...ui...] +/// void *cmds = nk_buffer_memory(&ctx.memory); +/// if (memcmp(cmds, last, ctx.memory.allocated)) { +/// memcpy(last,cmds,ctx.memory.allocated); +/// const struct nk_command *cmd = 0; +/// nk_foreach(cmd, &ctx) { +/// switch (cmd->type) { +/// case NK_COMMAND_LINE: +/// your_draw_line_function(...) +/// break; +/// case NK_COMMAND_RECT +/// your_draw_rect_function(...) +/// break; +/// case ...: +/// // [...] +/// } +/// } +/// } +/// nk_clear(&ctx); +/// } +/// nk_free(&ctx); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// Finally while using draw commands makes sense for higher abstracted platforms like +/// X11 and Win32 or drawing libraries it is often desirable to use graphics +/// hardware directly.

Calling any widgets outside these two functions will result in an +/// assert in debug or no state change in release mode.

+/// +/// Each window holds frame persistent state like position, size, flags, state tables, +/// and some garbage collected internal persistent widget state. Each window +/// is linked into a window stack list which determines the drawing and overlapping +/// order. The topmost window thereby is the currently active window.

+/// +/// To change window position inside the stack occurs either automatically by +/// user input by being clicked on or programmatically by calling `nk_window_focus`. +/// Windows by default are visible unless explicitly being defined with flag +/// `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag +/// `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling +/// `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.

+/// +/// #### Usage +/// To create and keep a window you have to call one of the two `nk_begin_xxx` +/// functions to start window declarations and `nk_end` at the end. Furthermore it +/// is recommended to check the return value of `nk_begin_xxx` and only process +/// widgets inside the window if the value is not 0.

+/* ============================================================================= + * + * LAYOUT + * + * ============================================================================= +/// ### Layouting +/// Layouting in general describes placing widget inside a window with position and size. +/// While in this particular implementation there are five different APIs for layouting +/// each with different trade offs between control and ease of use.

+/// +/// All layouting methods in this library are based around the concept of a row. +/// A row has a height the window content grows by and a number of columns and each +/// layouting method specifies how each widget is placed inside the row. +/// After a row has been allocated by calling a layouting functions and then +/// filled with widgets will advance an internal pointer over the allocated row.

+/// +/// To actually define a layout you just call the appropriate layouting function +/// and each subsequent widget call will place the widget as specified. Important +/// here is that if you define more widgets then columns defined inside the layout +/// functions it will allocate the next row without you having to make another layouting

+/// call. +/// +/// Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API +/// is that you have to define the row height for each. However the row height +/// often depends on the height of the font.

+/// +/// To fix that internally nuklear uses a minimum row height that is set to the +/// height plus padding of currently active font and overwrites the row height +/// value if zero.

+/// +/// If you manually want to change the minimum row height then +/// use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to +/// reset it back to be derived from font height.

+/// +/// Also if you change the font in nuklear it will automatically change the minimum +/// row height for you and. This means if you change the font but still want +/// a minimum row height smaller than the font you have to repush your value.

+/// +/// For actually more advanced UI I would even recommend using the `nk_layout_space_xxx` +/// layouting method in combination with a cassowary constraint solver (there are +/// some versions on github with permissive license model) to take over all control over widget +/// layouting yourself. However for quick and dirty layouting using all the other layouting +/// functions should be fine. +/// +/// #### Usage +/// 1. __nk_layout_row_dynamic__

+/// The easiest layouting function is `nk_layout_row_dynamic`. It provides each +/// widgets with same horizontal space inside the row and dynamically grows +/// if the owning window grows in width. So the number of columns dictates +/// the size of each widget dynamically by formula: +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// widget_width = (window_width - padding - spacing) * (1/colum_count) +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// Just like all other layouting APIs if you define more widget than columns this +/// library will allocate a new row and keep all layouting parameters previously +/// defined. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // first row with height: 30 composed of two widgets +/// nk_layout_row_dynamic(&ctx, 30, 2); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // second row with same parameter as defined above +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // third row uses 0 for height which will use auto layouting +/// nk_layout_row_dynamic(&ctx, 0, 2); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 2. __nk_layout_row_static__

+/// Another easy layouting function is `nk_layout_row_static`. It provides each +/// widget with same horizontal pixel width inside the row and does not grow +/// if the owning window scales smaller or bigger. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // first row with height: 30 composed of two widgets with width: 80 +/// nk_layout_row_static(&ctx, 30, 80, 2); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // second row with same parameter as defined above +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // third row uses 0 for height which will use auto layouting +/// nk_layout_row_static(&ctx, 0, 80, 2); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 3. __nk_layout_row_xxx__

+/// A little bit more advanced layouting API are functions `nk_layout_row_begin`, +/// `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly +/// specify each column pixel or window ratio in a row. It supports either +/// directly setting per column pixel width or widget window ratio but not +/// both. Furthermore it is a immediate mode API so each value is directly +/// pushed before calling a widget. Therefore the layout is not automatically +/// repeating like the last two layouting functions. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // first row with height: 25 composed of two widgets with width 60 and 40 +/// nk_layout_row_begin(ctx, NK_STATIC, 25, 2); +/// nk_layout_row_push(ctx, 60); +/// nk_widget(...); +/// nk_layout_row_push(ctx, 40); +/// nk_widget(...); +/// nk_layout_row_end(ctx); +/// // +/// // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75 +/// nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2); +/// nk_layout_row_push(ctx, 0.25f); +/// nk_widget(...); +/// nk_layout_row_push(ctx, 0.75f); +/// nk_widget(...); +/// nk_layout_row_end(ctx); +/// // +/// // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75 +/// nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2); +/// nk_layout_row_push(ctx, 0.25f); +/// nk_widget(...); +/// nk_layout_row_push(ctx, 0.75f); +/// nk_widget(...); +/// nk_layout_row_end(ctx); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 4. __nk_layout_row__

+/// The array counterpart to API nk_layout_row_xxx is the single nk_layout_row +/// functions. Instead of pushing either pixel or window ratio for every widget +/// it allows to define it by array. The trade of for less control is that +/// `nk_layout_row` is automatically repeating. Otherwise the behavior is the +/// same. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // two rows with height: 30 composed of two widgets with width 60 and 40 +/// const float size[] = {60,40}; +/// nk_layout_row(ctx, NK_STATIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75 +/// const float ratio[] = {0.25, 0.75}; +/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75 +/// const float ratio[] = {0.25, 0.75}; +/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 5. __nk_layout_row_template_xxx__

+/// The most complex and second most flexible API is a simplified flexbox version without +/// line wrapping and weights for dynamic widgets. It is an immediate mode API but +/// unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called +/// before calling the templated widgets. +/// The row template layout has three different per widget size specifier. The first +/// one is the `nk_layout_row_template_push_static` with fixed widget pixel width. +/// They do not grow if the row grows and will always stay the same. +/// The second size specifier is `nk_layout_row_template_push_variable` +/// which defines a minimum widget size but it also can grow if more space is available +/// not taken by other widgets. +/// Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic` +/// which are completely flexible and unlike variable widgets can even shrink +/// to zero if not enough space is provided. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // two rows with height: 30 composed of three widgets +/// nk_layout_row_template_begin(ctx, 30); +/// nk_layout_row_template_push_dynamic(ctx); +/// nk_layout_row_template_push_variable(ctx, 80); +/// nk_layout_row_template_push_static(ctx, 80); +/// nk_layout_row_template_end(ctx); +/// // +/// // first row +/// nk_widget(...); // dynamic widget can go to zero if not enough space +/// nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space +/// nk_widget(...); // static widget with fixed 80 pixel width +/// // +/// // second row same layout +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 6. __nk_layout_space_xxx__

+/// Finally the most flexible API directly allows you to place widgets inside the +/// window. The space layout API is an immediate mode API which does not support +/// row auto repeat and directly sets position and size of a widget. Position +/// and size hereby can be either specified as ratio of allocated space or +/// allocated space local position and pixel size.

The next + slightly more advanced features is font handling with vertex buffer output. + Finally the most complex API wise is using nuklear's font baking API. + + 1.) Using your own implementation without vertex buffer output + -------------------------------------------------------------- + So first up the easiest way to do font handling is by just providing a + `nk_user_font` struct which only requires the height in pixel of the used + font and a callback to calculate the width of a string. This way of handling + fonts is best fitted for using the normal draw shape command API where you + do all the text drawing yourself and the library does not require any kind + of deeper knowledge about which font handling mechanism you use. + IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist + over the complete life time! I know this sucks but it is currently the only + way to switch between fonts. + + float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) + { + your_font_type *type = handle.ptr; + float text_width = ...; + return text_width; + } + + struct nk_user_font font; + font.userdata.ptr = &your_font_class_or_struct; + font.height = your_font_height; + font.width = your_text_width_calculation; + + struct nk_context ctx; + nk_init_default(&ctx, &font); + + 2.) Using your own implementation with vertex buffer output + -------------------------------------------------------------- + While the first approach works fine if you don't want to use the optional + vertex buffer output it is not enough if you do. To get font handling working + for these cases you have to provide two additional parameters inside the + `nk_user_font`. First a texture atlas handle used to draw text as subimages + of a bigger font atlas texture and a callback to query a character's glyph + information (offset, size, ...). So it is still possible to provide your own + font and use the vertex buffer output. + + float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) + { + your_font_type *type = handle.ptr; + float text_width = ...; + return text_width; + } + void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint) + { + your_font_type *type = handle.ptr; + glyph.width = ...; + glyph.height = ...; + glyph.xadvance = ...; + glyph.uv[0].x = ...; + glyph.uv[0].y = ...; + glyph.uv[1].x = ...; + glyph.uv[1].y = ...; + glyph.offset.x = ...; + glyph.offset.y = ...; + } + + struct nk_user_font font; + font.userdata.ptr = &your_font_class_or_struct; + font.height = your_font_height; + font.width = your_text_width_calculation; + font.query = query_your_font_glyph; + font.texture.id = your_font_texture; + + struct nk_context ctx; + nk_init_default(&ctx, &font); + + 3.) Nuklear font baker + ------------------------------------ + The final approach if you do not have a font handling functionality or don't + want to use it in this library is by using the optional font baker. + The font baker APIs can be used to create a font plus font atlas texture + and can be used with or without the vertex buffer output. + + It still uses the `nk_user_font` struct and the two different approaches + previously stated still work. The font baker is not located inside + `nk_context` like all other systems since it can be understood as more of + an extension to nuklear and does not really depend on any `nk_context` state. + + Font baker need to be initialized first by one of the nk_font_atlas_init_xxx + functions. If you don't care about memory just call the default version + `nk_font_atlas_init_default` which will allocate all memory from the standard library. + If you want to control memory allocation but you don't care if the allocated + memory is temporary and therefore can be freed directly after the baking process + is over or permanent you can call `nk_font_atlas_init`. + + After successfully initializing the font baker you can add Truetype(.ttf) fonts from + different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`. + functions. Adding font will permanently store each font, font config and ttf memory block(!) + inside the font atlas and allows to reuse the font atlas. If you don't want to reuse + the font baker by for example adding additional fonts you can call + `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end). + + As soon as you added all fonts you wanted you can now start the baking process + for every selected glyph to image by calling `nk_font_atlas_bake`. + The baking process returns image memory, width and height which can be used to + either create your own image object or upload it to any graphics library. + No matter which case you finally have to call `nk_font_atlas_end` which + will free all temporary memory including the font atlas image so make sure + you created our texture beforehand. `nk_font_atlas_end` requires a handle + to your font texture or object and optionally fills a `struct nk_draw_null_texture` + which can be used for the optional vertex output. If you don't want it just + set the argument to `NULL`. + + At this point you are done and if you don't want to reuse the font atlas you + can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration + memory. Finally if you don't use the font atlas and any of it's fonts anymore + you need to call `nk_font_atlas_clear` to free all memory still being used. + + struct nk_font_atlas atlas; + nk_font_atlas_init_default(&atlas); + nk_font_atlas_begin(&atlas); + nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0); + nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0); + const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32); + nk_font_atlas_end(&atlas, nk_handle_id(texture), 0); + + struct nk_context ctx; + nk_init_default(&ctx, &font->handle); + while (1) { + + } + nk_font_atlas_clear(&atlas); + + The font baker API is probably the most complex API inside this library and + I would suggest reading some of my examples `example/` to get a grip on how + to use the font atlas.

Just like last the `nk_group` commit the main +/// advantage is that you optionally can minimize nuklears runtime +/// memory consumption or handle hash collisions. +/// - 2016/11/09 (1.26.0)- Added additional `nk_group` version to support external scrollbar +/// offset storage. Main advantage is that you can externalize +/// the memory management for the offset. It could also be helpful +/// if you have a hash collision in `nk_group_begin` but really +/// want the name. In addition I added `nk_list_view` which allows +/// to draw big lists inside a group without actually having to +/// commit the whole list to nuklear (issue #269). +/// - 2016/10/30 (1.25.1)- Fixed clipping rectangle bug inside `nk_draw_list` +/// - 2016/10/29 (1.25.0)- Pulled `nk_panel` memory management into nuklear and out of +/// the hands of the user. From now on users don't have to care +/// about panels unless they care about some information. If you +/// still need the panel just call `nk_window_get_panel`. +/// - 2016/10/21 (1.24.0)- Changed widget border drawing to stroked rectangle from filled +/// rectangle for less overdraw and widget background transparency. +/// - 2016/10/18 (1.23.0)- Added `nk_edit_focus` for manually edit widget focus control +/// - 2016/09/29 (1.22.7)- Fixed deduction of basic type in non `` compilation +/// - 2016/09/29 (1.22.6)- Fixed edit widget UTF-8 text cursor drawing bug +/// - 2016/09/28 (1.22.5)- Fixed edit widget UTF-8 text appending/inserting/removing +/// - 2016/09/28 (1.22.4)- Fixed drawing bug inside edit widgets which offset all text +/// text in every edit widget if one of them is scrolled. +/// - 2016/09/28 (1.22.3)- Fixed small bug in edit widgets if not active. The wrong +/// text length is passed. It should have been in bytes but +/// was passed as glyphes. +/// - 2016/09/20 (1.22.2)- Fixed color button size calculation +/// - 2016/09/20 (1.22.1)- Fixed some `nk_vsnprintf` behavior bugs and removed +/// `` again from `NK_INCLUDE_STANDARD_VARARGS`. +/// - 2016/09/18 (1.22.0)- C89 does not support vsnprintf only C99 and newer as well +/// as C++11 and newer. In addition to use vsnprintf you have +/// to include . So just defining `NK_INCLUDE_STD_VAR_ARGS` +/// is not enough. That behavior is now fixed. By default if +/// both varargs as well as stdio is selected I try to use +/// vsnprintf if not possible I will revert to vsprintf. If +/// varargs but not stdio was defined I will use my own function. +/// - 2016/09/15 (1.21.2)- Fixed panel `close` behavior for deeper panel levels +/// - 2016/09/15 (1.21.1)- Fixed C++ errors and wrong argument to `nk_panel_get_xxxx` +/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo, +/// and contextual which prevented closing in y-direction if +/// popup did not reach max height. +/// In addition the height parameter was changed into vec2 +/// for width and height to have more control over the popup size. +/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection +/// - 2016/09/13 (1.20.2)- Fixed slider behavior hopefully for the last time. This time +/// all calculation are correct so no more hackery. +/// - 2016/09/13 (1.20.1)- Internal change to divide window/panel flags into panel flags and types. +/// Suprisinly spend years in C and still happened to confuse types +/// with flags. Probably something to take note. +/// - 2016/09/08 (1.20.0)- Added additional helper function to make it easier to just +/// take the produced buffers from `nk_convert` and unplug the +/// iteration process from `nk_context`. So now you can +/// just use the vertex,element and command buffer + two pointer +/// inside the command buffer retrieved by calls `nk__draw_begin` +/// and `nk__draw_end` and macro `nk_draw_foreach_bounded`. +/// - 2016/09/08 (1.19.0)- Added additional asserts to make sure every `nk_xxx_begin` call +/// for windows, popups, combobox, menu and contextual is guarded by +/// `if` condition and does not produce false drawing output. +/// - 2016/09/08 (1.18.0)- Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT` +/// to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and +/// `NK_SYMBOL_RECT_OUTLINE`. +/// - 2016/09/08 (1.17.0)- Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE` +/// to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and +/// `NK_SYMBOL_CIRCLE_OUTLINE`. +/// - 2016/09/08 (1.16.0)- Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES` +/// is not defined by supporting the biggest compiler GCC, clang and MSVC. +/// - 2016/09/07 (1.15.3)- Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error +/// - 2016/09/04 (1.15.2)- Fixed wrong combobox height calculation +/// - 2016/09/03 (1.15.1)- Fixed gaps inside combo boxes in OpenGL +/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and +/// instead made it user provided. The range of types to convert +/// to is quite limited at the moment, but I would be more than +/// happy to accept PRs to add additional. +/// - 2016/08/30 (1.14.2) - Removed unused variables +/// - 2016/08/30 (1.14.1) - Fixed C++ build errors +/// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly +/// - 2016/08/30 (1.13.4) - Tweaked some default styling variables +/// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would +/// refrain from using slider with a big number of steps. +/// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the +/// window was in Read Only Mode. +/// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just +/// a hack for combo box and menu. +/// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since +/// it is bugged and causes issues in window selection. +/// - 2016/08/30 (1.12.0) - Removed scaler size.

Main reasoning is to be able to keep +/// typing after commiting. +/// - 2016/08/15 (1.09.4)- Removed redundant code +/// - 2016/08/15 (1.09.4)- Fixed negative numbers in `nk_strtoi` and remove unused variable +/// - 2016/08/15 (1.09.3)- Fixed `NK_WINDOW_BACKGROUND` flag behavior to select a background +/// window only as selected by hovering and not by clicking. +/// - 2016/08/14 (1.09.2)- Fixed a bug in font atlas which caused wrong loading +/// of glyphes for font with multiple ranges. +/// - 2016/08/12 (1.09.1)- Added additional function to check if window is currently +/// hidden and therefore not visible. +/// - 2016/08/12 (1.09.1)- nk_window_is_closed now queries the correct flag `NK_WINDOW_CLOSED` +/// instead of the old flag `NK_WINDOW_HIDDEN` +/// - 2016/08/09 (1.09.0) - Added additional double version to nk_property and changed +/// the underlying implementation to not cast to float and instead +/// work directly on the given values. +/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal +/// floating pointer number to string conversion for additional +/// precision. +/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal +/// string to floating point number conversion for additional +/// precision. +/// - 2016/08/08 (1.07.2)- Fixed compiling error without define NK_INCLUDE_FIXED_TYPE +/// - 2016/08/08 (1.07.1)- Fixed possible floating point error inside `nk_widget` leading +/// to wrong wiget width calculation which results in widgets falsly +/// becomming tagged as not inside window and cannot be accessed. +/// - 2016/08/08 (1.07.0) - Nuklear now differentiates between hiding a window (NK_WINDOW_HIDDEN) and +/// closing a window (NK_WINDOW_CLOSED). A window can be hidden/shown +/// by using `nk_window_show` and closed by either clicking the close +/// icon in a window or by calling `nk_window_close`. Only closed +/// windows get removed at the end of the frame while hidden windows +/// remain. +/// - 2016/08/08 (1.06.0) - Added `nk_edit_string_zero_terminated` as a second option to +/// `nk_edit_string` which takes, edits and outputs a '\0' terminated string. +/// - 2016/08/08 (1.05.4)- Fixed scrollbar auto hiding behavior +/// - 2016/08/08 (1.05.3)- Fixed wrong panel padding selection in `nk_layout_widget_space` +/// - 2016/08/07 (1.05.2)- Fixed old bug in dynamic immediate mode layout API, calculating +/// wrong item spacing and panel width. +///- 2016/08/07 (1.05.1)- Hopefully finally fixed combobox popup drawing bug +///- 2016/08/07 (1.05.0) - Split varargs away from NK_INCLUDE_STANDARD_IO into own +/// define NK_INCLUDE_STANDARD_VARARGS to allow more fine +/// grained controlled over library includes. +/// - 2016/08/06 (1.04.5)- Changed memset calls to NK_MEMSET +/// - 2016/08/04 (1.04.4)- Fixed fast window scaling behavior +/// - 2016/08/04 (1.04.3)- Fixed window scaling, movement bug which appears if you +/// move/scale a window and another window is behind it. +/// If you are fast enough then the window behind gets activated +/// and the operation is blocked. I now require activating +/// by hovering only if mouse is not pressed. +/// - 2016/08/04 (1.04.2)- Fixed changing fonts +/// - 2016/08/03 (1.04.1)- Fixed `NK_WINDOW_BACKGROUND` behavior +/// - 2016/08/03 (1.04.0) - Added color parameter to `nk_draw_image` +/// - 2016/08/03 (1.04.0) - Added additional window padding style attributes for +/// sub windows (combo, menu, ...) +/// - 2016/08/03 (1.04.0) - Added functions to show/hide software cursor +/// - 2016/08/03 (1.04.0) - Added `NK_WINDOW_BACKGROUND` flag to force a window +/// to be always in the background of the screen +/// - 2016/08/03 (1.03.2)- Removed invalid assert macro for NK_RGB color picker +/// - 2016/08/01 (1.03.1)- Added helper macros into header include guard +/// - 2016/07/29 (1.03.0) - Moved the window/table pool into the header part to +/// simplify memory management by removing the need to +/// allocate the pool. +/// - 2016/07/29 (1.02.0) - Added auto scrollbar hiding window flag which if enabled +/// will hide the window scrollbar after NK_SCROLLBAR_HIDING_TIMEOUT +/// seconds without window interaction. To make it work +/// you have to also set a delta time inside the `nk_context`. +/// - 2016/07/25 (1.01.1) - Fixed small panel and panel border drawing bugs +/// - 2016/07/15 (1.01.0) - Added software cursor to `nk_style` and `nk_context` +/// - 2016/07/15 (1.01.0) - Added const correctness to `nk_buffer_push' data argument +/// - 2016/07/15 (1.01.0) - Removed internal font baking API and simplified +/// font atlas memory management by converting pointer +/// arrays for fonts and font configurations to lists. +/// - 2016/07/15 (1.00.0) - Changed button API to use context dependend button +/// behavior instead of passing it for every function call. +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +/// ## Gallery +/// ![Figure [blue]: Feature overview with blue color styling](https://cloud.githubusercontent.com/assets/8057201/13538240/acd96876-e249-11e5-9547-5ac0b19667a0.png) +/// ![Figure [red]: Feature overview with red color styling](https://cloud.githubusercontent.com/assets/8057201/13538243/b04acd4c-e249-11e5-8fd2-ad7744a5b446.png) +/// ![Figure [widgets]: Widget overview](https://cloud.githubusercontent.com/assets/8057201/11282359/3325e3c6-8eff-11e5-86cb-cf02b0596087.png) +/// ![Figure [blackwhite]: Black and white](https://cloud.githubusercontent.com/assets/8057201/11033668/59ab5d04-86e5-11e5-8091-c56f16411565.png) +/// ![Figure [filexp]: File explorer](https://cloud.githubusercontent.com/assets/8057201/10718115/02a9ba08-7b6b-11e5-950f-adacdd637739.png) +/// ![Figure [opengl]: OpenGL Editor](https://cloud.githubusercontent.com/assets/8057201/12779619/2a20d72c-ca69-11e5-95fe-4edecf820d5c.png) +/// ![Figure [nodedit]: Node Editor](https://cloud.githubusercontent.com/assets/8057201/9976995/e81ac04a-5ef7-11e5-872b-acd54fbeee03.gif) +/// ![Figure [skinning]: Using skinning in Nuklear](https://cloud.githubusercontent.com/assets/8057201/15991632/76494854-30b8-11e6-9555-a69840d0d50b.png) +/// ![Figure [bf]: Heavy modified version](https://cloud.githubusercontent.com/assets/8057201/14902576/339926a8-0d9c-11e6-9fee-a8b73af04473.png) +/// +/// ## Credits +/// Developed by Micha Mettke and every direct or indirect github contributor.

it is 20-50% larger than the file + written by a decent optimizing implementation; though providing a custom + zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that. + This library is designed for source code compactness and simplicity, + not optimal image file size or run-time performance. + +BUILDING: + + You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h. + You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace + malloc,realloc,free. + You can #define STBIW_MEMMOVE() to replace memmove() + You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function + for PNG compression (instead of the builtin one), it must have the following signature: + unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality); + The returned data will be freed with STBIW_FREE() (free() by default), + so it must be heap allocated with STBIW_MALLOC() (malloc() by default), + +UNICODE: + + If compiling for Windows and you wish to use Unicode filenames, compile + with + #define STBIW_WINDOWS_UTF8 + and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert + Windows wchar_t filenames to utf8. + +USAGE: + + There are five functions, one for each image file format: + + int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality); + int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); + + void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically + + There are also five equivalent functions that use an arbitrary write function. You are + expected to open/close your file-equivalent before and after calling these: + + int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality); + + where the callback is: + void stbi_write_func(void *context, void *data, int size); + + You can configure it with these global variables: + int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE + int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression + int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode + + + You can define STBI_WRITE_NO_STDIO to disable the file variant of these + functions, so the library will not use stdio.h at all. However, this will + also disable HDR writing, because it requires stdio for formatted output. + + Each function returns 0 on failure and non-0 on success. + + The functions create an image file defined by the parameters. The image + is a rectangle of pixels stored from left-to-right, top-to-bottom. + Each pixel contains 'comp' channels of data stored interleaved with 8-bits + per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is + monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. + The *data pointer points to the first byte of the top-left-most pixel. + For PNG, "stride_in_bytes" is the distance in bytes from the first byte of + a row of pixels to the first byte of the next row of pixels. + + PNG creates output files with the same number of components as the input. + The BMP format expands Y to RGB in the file format and does not + output alpha. + + PNG supports writing rectangles of data even when the bytes storing rows of + data are not consecutive in memory (e.g. sub-rectangles of a larger image), + by supplying the stride between the beginning of adjacent rows. The other + formats do not. (Thus you cannot write a native-format BMP through the BMP + writer, both because it is in BGR order and because it may have padding + at the end of the line.) + + PNG allows you to set the deflate compression level by setting the global + variable 'stbi_write_png_compression_level' (it defaults to 8). + + HDR expects linear float data. Since the format is always 32-bit rgb(e) + data, alpha (if provided) is discarded, and for monochrome data it is + replicated across all three channels. + + TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed + data, set the global variable 'stbi_write_tga_with_rle' to 0. + + JPEG does ignore alpha channels in input data; quality is between 1 and 100. + Higher quality looks better but results in a bigger image. + JPEG baseline (no JPEG progressive). + +CREDITS: + + + Sean Barrett - PNG/BMP/TGA + Baldur Karlsson - HDR + Jean-Sebastien Guay - TGA monochrome + Tim Kelsey - misc enhancements + Alan Hickman - TGA RLE + Emmanuel Julien - initial file IO callback implementation + Jon Olick - original jo_jpeg.cpp code + Daniel Gibson - integrate JPEG, allow external zlib + Aarni Koskela - allow choosing PNG filter + + bugfixes: + github:Chribba + Guillaume Chereau + github:jry2 + github:romigrou + Sergio Gonzalez + Jonas Karlsson + Filip Wasil + Thatcher Ulrich + github:poppolopoppo + Patrick Boettcher + github:xeekworx + Cap Petschulat + Simon Rodriguez + Ivan Tikhonov + github:ignotion + Adam Schackart + Andrew Kensler + +LICENSE + + See end of file for license information. + +*/ + +#ifndef INCLUDE_STB_IMAGE_WRITE_H +#define INCLUDE_STB_IMAGE_WRITE_H + +#include + +// if STB_IMAGE_WRITE_STATIC causes problems, try defining STBIWDEF to 'inline' or 'static inline' +#ifndef STBIWDEF +#ifdef STB_IMAGE_WRITE_STATIC +#define STBIWDEF static +#else +#ifdef __cplusplus +#define STBIWDEF extern "C" +#else +#define STBIWDEF extern +#endif +#endif +#endif + +#ifndef STB_IMAGE_WRITE_STATIC // C++ forbids static forward declarations +STBIWDEF int stbi_write_tga_with_rle;

This is now obsolete. Please call io functions instead! + - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing, + with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. + + - REMOTE INPUTS SHARING & MOUSE EMULATION + - PS4/PS5 users: Consider emulating a mouse cursor with DualShock touch pad or a spare analog stick as a mouse-emulation fallback. + - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + run examples/libs/synergy/uSynergy.c (on your console/tablet/phone app) + in order to share your PC mouse/keyboard. + - See https://github.com/ocornut/imgui/wiki/Useful-Extensions#remoting for other remoting solutions. + - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. + Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs Dear ImGui to move your mouse cursor along with navigation movements. + When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. + When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, Dear ImGui will misbehave as it will see your mouse moving back & forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + PROGRAMMER GUIDE + ================ + + READ FIRST + ---------- + - Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki) + - Your code creates the UI every frame of your application loop, if your code doesn't run the UI is gone! + The UI can be highly dynamic, there are no construction or destruction steps, less superfluous + data retention on your side, less state duplication, less state synchronization, fewer bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + Or browse https://pthom.github.io/imgui_manual_online/manual/imgui_manual.html for interactive web version. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - This codebase aims to be highly optimized: + - A typical idle frame should never call malloc/free. + - We rely on a maximum of constant-time or O(N) algorithms. Limiting searches/scans as much as possible. + - We put particular energy in making sure performances are decent with typical "Debug" build settings as well. + Which mean we tend to avoid over-relying on "zero-cost abstraction" as they aren't zero-cost at all. + - This codebase aims to be both highly opinionated and highly flexible: + - This code works because of the things it choose to solve or not solve. + - C++: this is a pragmatic C-ish codebase: we don't use fancy C++ features, we don't include C++ headers, + and ImGui:: is a namespace. We rarely use member functions (and when we did, I am mostly regretting it now). + This is to increase compatibility, increase maintainability and facilitate use from other languages. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + We can can optionally export math operators for ImVec2/ImVec4 using IMGUI_DEFINE_MATH_OPERATORS, which we use internally. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction + (so don't use ImVector in your code or at our own risk!). + - Building: We don't use nor mandate a build system for the main library. + This is in an effort to ensure that it works in the real world aka with any esoteric build setup. + This is also because providing a build system for the main library would be of little-value. + The build problems are almost never coming from the main library but from specific backends. + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Update submodule or copy/overwrite every file. + - About imconfig.h: + - You may modify your copy of imconfig.h, in this case don't overwrite it. + - or you may locally branch to modify imconfig.h and merge/rebase latest. + - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to + specify a custom path for your imconfig.h file and instead not have to modify the default one. + + - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master". + - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it. Please report any issue to the GitHub page! + - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file. + - Try to keep your copy of Dear ImGui reasonably up to date! + + + GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE + --------------------------------------------------------------- + - See https://github.com/ocornut/imgui/wiki/Getting-Started. + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder. + - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. + - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. + + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + -------------------------------------- + EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder). + The sub-folders in examples/ contain examples applications following this structure. + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into screen + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Build and load the texture atlas into a texture + // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) + int width, height; + unsigned char* pixels = nullptr; + io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); + + // At this point you've got the texture data and you need to upload that to your graphic system: + // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'. + // This will be passed back to your via the renderer.

We try to make the breakage minor and easy to fix. + Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. + When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. + You can read releases logs https://github.com/ocornut/imgui/releases for more details. + +(Docking/Viewport Branch) + - 2023/XX/XX (1.XXXX) - when multi-viewports are enabled, all positions will be in your natural OS coordinates space. It means that: + - reference to hard-coded positions such as in SetNextWindowPos(ImVec2(0,0)) are probably not what you want anymore. + you may use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos) + - likewise io.MousePos and GetMousePos() will use OS coordinates. + If you query mouse positions to interact with non-imgui coordinates you will need to offset them, e.g. subtract GetWindowViewport()->Pos. + + - 2023/07/12 (1.89.8) - ImDrawData: CmdLists now owned, changed from ImDrawList** to ImVector. Majority of users shouldn't be affected, but you cannot compare to NULL nor reassign manually anymore. Instead use AddDrawList(). (#6406, #4879, #1878) + - 2023/06/28 (1.89.7) - overlapping items: obsoleted 'SetItemAllowOverlap()' (called after item) in favor of calling 'SetNextItemAllowOverlap()' (called before item). 'SetItemAllowOverlap()' didn't and couldn't work reliably since 1.89 (2022-11-15). + - 2023/06/28 (1.89.7) - overlapping items: renamed 'ImGuiTreeNodeFlags_AllowItemOverlap' to 'ImGuiTreeNodeFlags_AllowOverlap', 'ImGuiSelectableFlags_AllowItemOverlap' to 'ImGuiSelectableFlags_AllowOverlap'. Kept redirecting enums (will obsolete). + - 2023/06/28 (1.89.7) - overlapping items: IsItemHovered() now by default return false when querying an item using AllowOverlap mode which is being overlapped. Use ImGuiHoveredFlags_AllowWhenOverlappedByItem to revert to old behavior. + - 2023/06/28 (1.89.7) - overlapping items: Selectable and TreeNode don't allow overlap when active so overlapping widgets won't appear as hovered. While this fixes a common small visual issue, it also means that calling IsItemHovered() after a non-reactive elements - e.g. Text() - overlapping an active one may fail if you don't use IsItemHovered(ImGuiHoveredFlags_AllowWhenBlockedByActiveItem). (#6610) + - 2023/06/20 (1.89.7) - moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal. As the fields were added in 1.89 and expected to be left unchanged by most users, or only tweaked once during app initialization, we are exceptionally accepting the breakage. + - 2023/05/30 (1.89.6) - backends: renamed "imgui_impl_sdlrenderer.cpp" to "imgui_impl_sdlrenderer2.cpp" and "imgui_impl_sdlrenderer.h" to "imgui_impl_sdlrenderer2.h". This is in prevision for the future release of SDL3. + - 2023/05/22 (1.89.6) - listbox: commented out obsolete/redirecting functions that were marked obsolete more than two years ago: + - ListBoxHeader() -> use BeginListBox() (note how two variants of ListBoxHeader() existed. Check commented versions in imgui.h for reference) + - ListBoxFooter() -> use EndListBox() + - 2023/05/15 (1.89.6) - clipper: commented out obsolete redirection constructor 'ImGuiListClipper(int items_count, float items_height = -1.0f)' that was marked obsolete in 1.79. Use default constructor + clipper.Begin(). + - 2023/05/15 (1.89.6) - clipper: renamed ImGuiListClipper::ForceDisplayRangeByIndices() to ImGuiListClipper::IncludeRangeByIndices(). + - 2023/03/14 (1.89.4) - commented out redirecting enums/functions names that were marked obsolete two years ago: + - ImGuiSliderFlags_ClampOnInput -> use ImGuiSliderFlags_AlwaysClamp + - ImGuiInputTextFlags_AlwaysInsertMode -> use ImGuiInputTextFlags_AlwaysOverwrite + - ImDrawList::AddBezierCurve() -> use ImDrawList::AddBezierCubic() + - ImDrawList::PathBezierCurveTo() -> use ImDrawList::PathBezierCubicCurveTo() + - 2023/03/09 (1.89.4) - renamed PushAllowKeyboardFocus()/PopAllowKeyboardFocus() to PushTabStop()/PopTabStop(). Kept inline redirection functions (will obsolete). + - 2023/03/09 (1.89.4) - tooltips: Added 'bool' return value to BeginTooltip() for API consistency. Please only submit contents and call EndTooltip() if BeginTooltip() returns true. In reality the function will _currently_ always return true, but further changes down the line may change this, best to clarify API sooner. + - 2023/02/15 (1.89.4) - moved the optional "courtesy maths operators" implementation from imgui_internal.h in imgui.h. + Even though we encourage using your own maths types and operators by setting up IM_VEC2_CLASS_EXTRA, + it has been frequently requested by people to use our own. We had an opt-in define which was + previously fulfilled in imgui_internal.h. It is now fulfilled in imgui.h. (#6164) + - OK: #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui.h" / #include "imgui_internal.h" + - Error: #include "imgui.h" / #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui_internal.h" + - 2023/02/07 (1.89.3) - backends: renamed "imgui_impl_sdl.cpp" to "imgui_impl_sdl2.cpp" and "imgui_impl_sdl.h" to "imgui_impl_sdl2.h". (#6146) This is in prevision for the future release of SDL3. + - 2022/10/26 (1.89) - commented out redirecting OpenPopupContextItem() which was briefly the name of OpenPopupOnItemClick() from 1.77 to 1.79. + - 2022/10/12 (1.89) - removed runtime patching of invalid "%f"/"%0.f" format strings for DragInt()/SliderInt(). This was obsoleted in 1.61 (May 2018). See 1.61 changelog for details. + - 2022/09/26 (1.89) - renamed and merged keyboard modifiers key enums and flags into a same set. Kept inline redirection enums (will obsolete). + - ImGuiKey_ModCtrl and ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl + - ImGuiKey_ModShift and ImGuiModFlags_Shift -> ImGuiMod_Shift + - ImGuiKey_ModAlt and ImGuiModFlags_Alt -> ImGuiMod_Alt + - ImGuiKey_ModSuper and ImGuiModFlags_Super -> ImGuiMod_Super + the ImGuiKey_ModXXX were introduced in 1.87 and mostly used by backends. + the ImGuiModFlags_XXX have been exposed in imgui.h but not really used by any public api only by third-party extensions. + exceptionally commenting out the older ImGuiKeyModFlags_XXX names ahead of obsolescence schedule to reduce confusion and because they were not meant to be used anyway. + - 2022/09/20 (1.89) - ImGuiKey is now a typed enum, allowing ImGuiKey_XXX symbols to be named in debuggers. + this will require uses of legacy backend-dependent indices to be casted, e.g. + - with imgui_impl_glfw: IsKeyPressed(GLFW_KEY_A) -> IsKeyPressed((ImGuiKey)GLFW_KEY_A); + - with imgui_impl_win32: IsKeyPressed('A') -> IsKeyPressed((ImGuiKey)'A') + - etc. However if you are upgrading code you might well use the better, backend-agnostic IsKeyPressed(ImGuiKey_A) now! + - 2022/09/12 (1.89) - removed the bizarre legacy default argument for 'TreePush(const void* ptr = NULL)', always pass a pointer value explicitly. NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr); + - 2022/09/05 (1.89) - commented out redirecting functions/enums names that were marked obsolete in 1.77 and 1.78 (June 2020): + - DragScalar(), DragScalarN(), DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f. + - SliderScalar(), SliderScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f. + - BeginPopupContextWindow(const char*, ImGuiMouseButton, bool) -> use BeginPopupContextWindow(const char*, ImGuiPopupFlags) + - 2022/09/02 (1.89) - obsoleted using SetCursorPos()/SetCursorScreenPos() to extend parent window/cell boundaries. + this relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item. + - previously this would make the window content size ~200x200: + Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End(); + - instead, please submit an item: + Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End(); + - alternative: + Begin(...) + Dummy(ImVec2(200,200)) + End(); + - content size is now only extended when submitting an item! + - with '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will now be detected and assert. + - without '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will silently be fixed until we obsolete it. + - 2022/08/03 (1.89) - changed signature of ImageButton() function. Kept redirection function (will obsolete). + - added 'const char* str_id' parameter + removed 'int frame_padding = -1' parameter. + - old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1)); + - used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values. + - had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer. + - new signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1)); + - requires an explicit identifier. You may still use e.g. PushID() calls and then pass an empty identifier. + - always uses style.FramePadding for padding, to be consistent with other buttons. You may use PushStyleVar() to alter this. + - 2022/07/08 (1.89) - inputs: removed io.NavInputs[] and ImGuiNavInput enum (following 1.87 changes). + - Official backends from 1.87+ -> no issue. + - Official backends from 1.60 to 1.86 -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need updating! + - Custom backends not writing to io.NavInputs[] -> no issue. + - Custom backends writing to io.NavInputs[] -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need fixing! + - TL;DR: Backends should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[]. + - 2022/06/15 (1.88) - renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness. kept support for old define (will obsolete). + - 2022/05/03 (1.88) - backends: osx: removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. All ImGui_ImplOSX_HandleEvent() calls should be removed as they are now unnecessary. + - 2022/04/05 (1.88) - inputs: renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO. + - 2022/01/20 (1.87) - inputs: reworded gamepad IO. + - Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values. + - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used). + - 2022/01/17 (1.87) - inputs: reworked mouse IO. + - Backend writing to io.MousePos -> backend should call io.AddMousePosEvent() + - Backend writing to io.MouseDown[] -> backend should call io.AddMouseButtonEvent() + - Backend writing to io.MouseWheel -> backend should call io.AddMouseWheelEvent() + - Backend writing to io.MouseHoveredViewport -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only] + note: for all calls to IO new functions, the Dear ImGui context should be bound/current. + read https://github.com/ocornut/imgui/issues/4921 for details. + - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details. + - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX) + - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX) + - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to stil function with legacy key codes). + - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiMod_XXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiMod_XXX values.* + - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert. + - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper. + - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. + - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'. + - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019) + - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen() + - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x + - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing()); + - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect + - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex + - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings + - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function. + - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful. + - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019): + - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList() + - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder + - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). + - if you are using official backends from the source tree: you have nothing to do. + - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID(). + - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags. + - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft + - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight + - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc. + flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API. + breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners": + - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use) + - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use) + - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use) + - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f. + this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok. + the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts. + legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise). + - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018): + - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY() + - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing. + - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future. + - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. + - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed. + - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete). + - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete). + - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). + - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. + - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. + - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): + - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). + - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg + - ImGuiInputTextCallback -> use ImGuiTextEditCallback + - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData + - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). + - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! + - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. + - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures + - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): + - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend + - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) + - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT + - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT + - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): + - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. + - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. + - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). + - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). + - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. + - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! + - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). + replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). + worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: + - if you omitted the 'power' parameter (likely!), you are not affected. + - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. + - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. + see https://github.com/ocornut/imgui/issues/3361 for all details. + kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used. + for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. + - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. + - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] + - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. + - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. + when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. + - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing + - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused().

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes. The undo system does no memory allocations, so +// it grows STB_TexteditState by the worst-case storage which is (in bytes): +// +// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT +// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHARCOUNT +// +// +// Implementation mode: +// +// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it +// will compile the implementation of the text edit widget, depending +// on a large number of symbols which must be defined before the include. +// +// The implementation is defined only as static functions. You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit. This is true for both plain text and +// rich text; even with rich text stb_truetype interacts with your +// code as if there was an array of all the displayed characters. +// +// Symbols that must be the same in header-file and implementation mode: +// +// STB_TEXTEDIT_CHARTYPE the character type +// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// Symbols you must define for implementation mode: +// +// STB_TEXTEDIT_STRING the type of object representing a string being edited, +// typically this is a wrapper object with other data you need +// +// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) +// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters +// starting from character #n (see discussion below) +// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character +// to the xpos of the i+1'th char for a line of characters +// starting at character #n (i.e. accounts for kerning +// with previous char) +// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character +// (return type is int, -1 means not valid to insert) +// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based +// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize +// as manually wordwrapping for end-of-line positioning +// +// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i +// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) +// +// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key +// +// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left +// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right +// STB_TEXTEDIT_K_UP keyboard input to move cursor up +// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down +// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page +// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page +// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME +// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END +// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME +// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END +// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor +// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor +// STB_TEXTEDIT_K_UNDO keyboard input to perform undo +// STB_TEXTEDIT_K_REDO keyboard input to perform redo +// +// Optional: +// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode +// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), +// required for default WORDLEFT/WORDRIGHT handlers +// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to +// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to +// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT +// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT +// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line +// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line +// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text +// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text +// +// Keyboard input must be encoded as a single integer value; e.g. a character code +// and some bitflags that represent shift states. to simplify the interface, SHIFT must +// be a bitflag, so we can test the shifted state of cursor movements to allow selection, +// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. +// +// You can encode other things, such as CONTROL or ALT, in additional bits, and +// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, +// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN +// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, +// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the +// API below. The control keys will only match WM_KEYDOWN events because of the +// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN +// bit so it only decodes WM_CHAR events. +// +// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed +// row of characters assuming they start on the i'th character--the width and +// the height and the number of characters consumed. This allows this library +// to traverse the entire layout incrementally. You need to compute word-wrapping +// here. +// +// Each textfield keeps its own insert mode state, which is not how normal +// applications work.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you wante before including. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers.

Thus, anti-aliasing of intersecting shapes may look wrong.

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to .
