Application - Modular UI Components + * A simple desktop GUI application using GLFW3 and Nuklear with modular component architecture + * + * MODULAR COMPONENT STRUCTURE: + * + * This application demonstrates a clean, modular approach to UI component organization: + * + * 1. UI STATE MANAGEMENT: + * - Centralized state in ui_state_t structure + * - Clean separation between UI rendering and state management + * - Easy state reset and manipulation functions + * + * 2. COMPONENT INTERFACE: + * - Each UI component is a function with signature: void render_*_component(nk_context*, ui_state_t*) + * - Components are registered in ui_components[] array + * - Components can be enabled/disabled individually + * - Easy to add new components by implementing the interface and adding to registry + * + * 3. CLEAN SEPARATION: + * - GLFW window management is separate from UI rendering + * - Nuklear integration is isolated in init/cleanup functions + * - Application logic is separated from rendering logic + * + * 4. EXTENSIBILITY: + * - Adding new components requires: implement render function + add to registry + * - State management is centralized and easily extensible + * - Component enable/disable functionality built-in + * + * HOW TO ADD NEW COMPONENTS: + * 1. Add state variables to ui_state_t if needed + * 2. Implement render_*_component(ctx, state) function + * 3. Add component to ui_components[] array + * 4.

Changelog section +9. Gallery section +10. 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 +- [Code available on github](https://github.com/Immediate-Mode-UI/Nuklear/) + +## 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 #including 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_STANDARD_BOOL | If defined it will include header `` for nk_bool otherwise nuklear defines nk_bool as int. +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. +NK_UINT_DRAW_INDEX | Defining this will set the size of vertex index elements when using NK_VERTEX_BUFFER_OUTPUT to 32bit instead of the default of 16bit +NK_KEYSTATE_BASED_INPUT | Define this if your backend uses key state for each frame rather than key press/release events +NK_IS_WORD_BOUNDARY(c) | Define this to a function macro that takes a single nk_rune (nk_uint) and returns true if it's a word separator. If not defined, uses the default definition (see nk_is_word_boundary()) + +!!! 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_STANDARD_BOOL + - NK_INCLUDE_VERTEX_BUFFER_OUTPUT + - NK_INCLUDE_FONT_BAKING + - NK_INCLUDE_DEFAULT_FONT + - NK_INCLUDE_STANDARD_VARARGS + - NK_INCLUDE_COMMAND_USERDATA + - NK_UINT_DRAW_INDEX + +### 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_INV_SQRT | You can define this to your own inverse 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. + +!!!

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. Therefore it is possible to just define + * `NK_INCLUDE_VERTEX_BUFFER_OUTPUT` which includes optional vertex output. + * To access the vertex output you first have to convert all draw commands into + * vertexes by calling `nk_convert` which takes in your preferred vertex format. + * After successfully converting all draw commands just iterate over and execute all + * vertex draw commands: + * + * ```c + * // fill configuration + * struct your_vertex + * { + * float pos[2];

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. Either way you have to call + * `nk_end` at the end of window declarations. Furthermore, do not attempt to + * nest `nk_begin_xxx` calls which will hopefully result in an assert or if not + * in a segmentation fault. + * + * ```c + * if (nk_begin_xxx(...) { + * // [... widgets ...] + * } + * nk_end(ctx); + * ``` + * + * In the grand concept window and widget declarations need to occur after input + * handling and before drawing to screen. Not doing so can result in higher + * latency or at worst invalid behavior. Furthermore make sure that `nk_clear` + * is called at the end of the frame. While nuklear's default platform backends + * already call `nk_clear` for you if you write your own backend not calling + * `nk_clear` can cause asserts or even worse undefined behavior. + * + * ```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_xxx(...); + * } + * } + * nk_input_end(&ctx); + * + * if (nk_begin_xxx(...) { + * //[...] + * } + * nk_end(ctx); + * + * const struct nk_command *cmd = 0; + * nk_foreach(cmd, &ctx) { + * 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); + * ``` + * + * # Reference + * Function | Description + * ------------------------------------|---------------------------------------- + * \ref nk_begin | Starts a new window; needs to be called every frame for every window (unless hidden) or otherwise the window gets removed + * \ref nk_begin_titled | Extended window start with separated title and identifier to allow multiple windows with same name but not title + * \ref nk_end | Needs to be called at the end of the window building process to process scaling, scrollbars and general cleanup + * + * \ref nk_window_find | Finds and returns the window with give name + * \ref nk_window_get_bounds | Returns a rectangle with screen position and size of the currently processed window. + * \ref nk_window_get_position | Returns the position of the currently processed window + * \ref nk_window_get_size | Returns the size with width and height of the currently processed window + * \ref nk_window_get_width | Returns the width of the currently processed window + * \ref nk_window_get_height | Returns the height of the currently processed window + * \ref nk_window_get_panel | Returns the underlying panel which contains all processing state of the current window + * \ref nk_window_get_content_region | Returns the position and size of the currently visible and non-clipped space inside the currently processed window + * \ref nk_window_get_content_region_min | Returns the upper rectangle position of the currently visible and non-clipped space inside the currently processed window + * \ref nk_window_get_content_region_max | Returns the upper rectangle position of the currently visible and non-clipped space inside the currently processed window + * \ref nk_window_get_content_region_size | Returns the size of the currently visible and non-clipped space inside the currently processed window + * \ref nk_window_get_canvas | Returns the draw command buffer.

+ * + * 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/column_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 ratio[] = {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. Since this API is quite + * powerful there are a number of utility functions to get the available space + * and convert between local allocated space and screen space. + * + * ```c + * if (nk_begin_xxx(...) { + * // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) + * nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX); + * nk_layout_space_push(ctx, nk_rect(0,0,150,200)); + * nk_widget(...); + * nk_layout_space_push(ctx, nk_rect(200,200,100,200)); + * nk_widget(...); + * nk_layout_space_end(ctx); + * // + * // dynamic row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) + * nk_layout_space_begin(ctx, NK_DYNAMIC, 500, INT_MAX); + * nk_layout_space_push(ctx, nk_rect(0.5,0.5,0.1,0.1)); + * nk_widget(...); + * nk_layout_space_push(ctx, nk_rect(0.7,0.6,0.1,0.1)); + * nk_widget(...); + * } + * nk_end(...); + * ``` + * + * # Reference + * Function | Description + * ---------------------------------------------|------------------------------------ + * \ref nk_layout_set_min_row_height | Set the currently used minimum row height to a specified value + * \ref nk_layout_reset_min_row_height | Resets the currently used minimum row height to font height + * \ref nk_layout_widget_bounds | Calculates current width a static layout row can fit inside a window + * \ref nk_layout_ratio_from_pixel | Utility functions to calculate window ratio from pixel size + * \ref nk_layout_row_dynamic | Current layout is divided into n same sized growing columns + * \ref nk_layout_row_static | Current layout is divided into n same fixed sized columns + * \ref nk_layout_row_begin | Starts a new row with given height and number of columns + * \ref nk_layout_row_push | Pushes another column with given size or window ratio + * \ref nk_layout_row_end | Finished previously started row + * \ref nk_layout_row | Specifies row columns in array as either window ratio or size + * \ref nk_layout_row_template_begin | Begins the row template declaration + * \ref nk_layout_row_template_push_dynamic | Adds a dynamic column that dynamically grows and can go to zero if not enough space + * \ref nk_layout_row_template_push_variable | Adds a variable column that dynamically grows but does not shrink below specified pixel width + * \ref nk_layout_row_template_push_static | Adds a static column that does not grow and will always have the same size + * \ref nk_layout_row_template_end | Marks the end of the row template + * \ref nk_layout_space_begin | Begins a new layouting space that allows to specify each widgets position and size + * \ref nk_layout_space_push | Pushes position and size of the next widget in own coordinate space either as pixel or ratio + * \ref nk_layout_space_end | Marks the end of the layouting space + * \ref nk_layout_space_bounds | Callable after nk_layout_space_begin and returns total space allocated + * \ref nk_layout_space_to_screen | Converts vector from nk_layout_space coordinate space into screen space + * \ref nk_layout_space_to_local | Converts vector from screen space into nk_layout_space coordinates + * \ref nk_layout_space_rect_to_screen | Converts rectangle from nk_layout_space coordinate space into screen space + * \ref nk_layout_space_rect_to_local | Converts rectangle from screen space into nk_layout_space coordinates + */ + + + +enum nk_widget_align { + NK_WIDGET_ALIGN_LEFT = 0x01, + NK_WIDGET_ALIGN_CENTERED = 0x02, + NK_WIDGET_ALIGN_RIGHT = 0x04, + NK_WIDGET_ALIGN_TOP = 0x08, + NK_WIDGET_ALIGN_MIDDLE = 0x10, + NK_WIDGET_ALIGN_BOTTOM = 0x20 +}; +enum nk_widget_alignment { + NK_WIDGET_LEFT = NK_WIDGET_ALIGN_MIDDLE|NK_WIDGET_ALIGN_LEFT, + NK_WIDGET_CENTERED = NK_WIDGET_ALIGN_MIDDLE|NK_WIDGET_ALIGN_CENTERED, + NK_WIDGET_RIGHT = NK_WIDGET_ALIGN_MIDDLE|NK_WIDGET_ALIGN_RIGHT +}; + +/** + * Sets the currently used minimum row height. + * !!! \warning + * The passed height needs to include both your preferred row height + * as well as padding.

+/* =============================================================== + * + * FONT + * + * ===============================================================*/ +/** + * \page Font + * Font handling in this library was designed to be quite customizable and lets + * you decide what you want to use and what you want to provide. There are three + * different ways to use the font atlas. The first two will use your font + * handling scheme and only requires essential data to run nuklear. 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. + * + * # 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. + * + * ```c + * 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); + * ``` + * # 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. + * + * ```c + * 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); + * ``` + * + * # 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. + * + * ```c + * 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.

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.

Auto layout now only +/// comes in effect if you pass in zero was row height argument. +/// - 2017/06/08 (1.40.0) - BREAKING CHANGE: while not directly API breaking it will change +/// how layouting works. From now there will be an internal minimum +/// row height derived from font height. If you need a row smaller than +/// that you can directly set it by `nk_layout_set_min_row_height` and +/// reset the value back by calling `nk_layout_reset_min_row_height. +/// - 2017/06/08 (1.39.1) - Fixed property text edit handling bug caused by past `nk_widget` fix. +/// - 2017/06/08 (1.39.0) - Added function to retrieve window space without calling a `nk_layout_xxx` function. +/// - 2017/06/06 (1.38.5) - Fixed `nk_convert` return flag for command buffer. +/// - 2017/05/23 (1.38.4) - Fixed activation behavior for widgets partially clipped. +/// - 2017/05/10 (1.38.3) - Fixed wrong min window size mouse scaling over boundaries. +/// - 2017/05/09 (1.38.2) - Fixed vertical scrollbar drawing with not enough space. +/// - 2017/05/09 (1.38.1) - Fixed scaler dragging behavior if window size hits minimum size. +/// - 2017/05/06 (1.38.0) - Added platform double-click support. +/// - 2017/04/20 (1.37.1) - Fixed key repeat found inside glfw demo backends. +/// - 2017/04/20 (1.37.0) - Extended properties with selection and clipboard support. +/// - 2017/04/20 (1.36.2) - Fixed #405 overlapping rows with zero padding and spacing. +/// - 2017/04/09 (1.36.1) - Fixed #403 with another widget float error. +/// - 2017/04/09 (1.36.0) - Added window `NK_WINDOW_NO_INPUT` and `NK_WINDOW_NOT_INTERACTIVE` flags. +/// - 2017/04/09 (1.35.3) - Fixed buffer heap corruption. +/// - 2017/03/25 (1.35.2) - Fixed popup overlapping for `NK_WINDOW_BACKGROUND` windows. +/// - 2017/03/25 (1.35.1) - Fixed windows closing behavior. +/// - 2017/03/18 (1.35.0) - Added horizontal scroll requested in #377. +/// - 2017/03/18 (1.34.3) - Fixed long window header titles. +/// - 2017/03/04 (1.34.2) - Fixed text edit filtering. +/// - 2017/03/04 (1.34.1) - Fixed group closable flag. +/// - 2017/02/25 (1.34.0) - Added custom draw command for better language binding support. +/// - 2017/01/24 (1.33.0) - Added programmatic way to remove edit focus. +/// - 2017/01/24 (1.32.3) - Fixed wrong define for basic type definitions for windows. +/// - 2017/01/21 (1.32.2) - Fixed input capture from hidden or closed windows. +/// - 2017/01/21 (1.32.1) - Fixed slider behavior and drawing. +/// - 2017/01/13 (1.32.0) - Added flag to put scaler into the bottom left corner. +/// - 2017/01/13 (1.31.0) - Added additional row layouting method to combine both +/// dynamic and static widgets. +/// - 2016/12/31 (1.30.0) - Extended scrollbar offset from 16-bit to 32-bit. +/// - 2016/12/31 (1.29.2) - Fixed closing window bug of minimized windows. +/// - 2016/12/03 (1.29.1) - Fixed wrapped text with no separator and C89 error. +/// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters. +/// - 2016/11/22 (1.28.6) - Fixed window minimized closing bug. +/// - 2016/11/19 (1.28.5) - Fixed abstract combo box closing behavior. +/// - 2016/11/19 (1.28.4) - Fixed tooltip flickering. +/// - 2016/11/19 (1.28.3) - Fixed memory leak caused by popup repeated closing. +/// - 2016/11/18 (1.28.2) - Fixed memory leak caused by popup panel allocation. +/// - 2016/11/10 (1.28.1) - Fixed some warnings and C++ error. +/// - 2016/11/10 (1.28.0) - Added additional `nk_button` versions which allows to directly +/// pass in a style struct to change buttons visual. +/// - 2016/11/10 (1.27.0) - Added additional `nk_tree` versions to support external state +/// storage. 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 glyphs. +/// - 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.

Currently limited to `NK_WINDOW_MAX_NAME` +/// which in term can be redefined if not big enough. +/// - 2016/08/26 (1.10.0) - Added stacks for temporary style/UI changes in code. +/// - 2016/08/25 (1.10.0) - Changed `nk_input_is_key_pressed` and 'nk_input_is_key_released' +/// to account for key press and release happening in one frame. +/// - 2016/08/25 (1.10.0) - Added additional nk_edit flag to directly jump to the end on activate. +/// - 2016/08/17 (1.09.6) - Removed invalid check for value zero in `nk_propertyx`. +/// - 2016/08/16 (1.09.5) - Fixed ROM mode for deeper levels of popup windows parents. +/// - 2016/08/15 (1.09.4) - Editbox are now still active if enter was pressed with flag +/// `NK_EDIT_SIG_ENTER`. Main reasoning is to be able to keep +/// typing after committing. +/// - 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 glyphs 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 widget width calculation which results in widgets falsely +/// becoming 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 dependent 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.
