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. There are a number of details I left out. For example +how to merge fonts, configure a font with `nk_font_config` to use other languages, +use another texture coordinate format and a lot more: +```c + struct nk_font_config cfg = nk_font_config(font_pixel_height); + cfg.merge_mode = nk_false or nk_true; + cfg.range = nk_font_korean_glyph_ranges(); + cfg.coord_type = NK_COORD_PIXEL; + nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg); +``` +### Memory Buffer +A basic (double)-buffer with linear allocation and resetting as only +freeing policy. The buffer's main purpose is to control all memory management +inside the GUI toolkit and still leave memory control as much as possible in +the hand of the user while also making sure the library is easy to use if +not as much control is needed. +In general all memory inside this library can be provided from the user in +three different ways. + +The first way and the one providing most control is by just passing a fixed +size memory block. In this case all control lies in the hand of the user +since he can exactly control where the memory comes from and how much memory +the library should consume. Of course using the fixed size API removes the +ability to automatically resize a buffer if not enough memory is provided so +you have to take over the resizing. While being a fixed sized buffer sounds +quite limiting, it is very effective in this library since the actual memory +consumption is quite stable and has a fixed upper bound for a lot of cases. + +If you don't want to think about how much memory the library should allocate +at all time or have a very dynamic UI with unpredictable memory consumption +habits but still want control over memory allocation you can use the dynamic +allocator based API. The allocator consists of two callbacks for allocating +and freeing memory and optional userdata so you can plugin your own allocator. + +The final and easiest way can be used by defining +NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory +allocation functions malloc and free and takes over complete control over +memory in this library. +### Text Editor +Editing text in this library is handled by either `nk_edit_string` or +`nk_edit_buffer`. But like almost everything in this library there are multiple +ways of doing it and a balance between control and ease of use with memory +as well as functionality controlled by flags. +This library generally allows three different levels of memory control: +First of is the most basic way of just providing a simple char array with +string length. This method is probably the easiest way of handling simple +user text input. Main upside is complete control over memory while the biggest +downside in comparison with the other two approaches is missing undo/redo. +For UIs that require undo/redo the second way was created. It is based on +a fixed size nk_text_edit struct, which has an internal undo/redo stack. +This is mainly useful if you want something more like a text editor but don't want +to have a dynamically growing buffer. +The final way is using a dynamically growing nk_text_edit struct, which +has both a default version if you don't care where memory comes from and an +allocator version if you do. While the text editor is quite powerful for its +complexity I would not recommend editing gigabytes of data with it. +It is rather designed for uses cases which make sense for a GUI library not for +an full blown text editor. +### Drawing +This library was designed to be render backend agnostic so it does +not draw anything to screen. Instead all drawn shapes, widgets +are made of, are buffered into memory and make up a command queue. +Each frame therefore fills the command buffer with draw commands +that then need to be executed by the user and his own render backend. +After that the command buffer needs to be cleared and a new frame can be +started. It is probably important to note that the command buffer is the main +drawing API and the optional vertex buffer API only takes this format and +converts it into a hardware accessible format. + +To use the command queue to draw your own widgets you can access the +command buffer of each window by calling `nk_window_get_canvas` after +previously having called `nk_begin`: + +```c + void draw_red_rectangle_widget(struct nk_context *ctx) + { + struct nk_command_buffer *canvas; + struct nk_input *input = &ctx->input; + canvas = nk_window_get_canvas(ctx); + + struct nk_rect space; + enum nk_widget_layout_states state; + state = nk_widget(&space, ctx); + if (!state) return; + + if (state != NK_WIDGET_ROM) + update_your_widget_by_user_input(...); + nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0)); + } + + if (nk_begin(...)) { + nk_layout_row_dynamic(ctx, 25, 1); + draw_red_rectangle_widget(ctx); + } + nk_end(..) + +``` +Important to know if you want to create your own widgets is the `nk_widget` +call. It allocates space on the panel reserved for this widget to be used, +but also returns the state of the widget space. If your widget is not seen and does +not have to be updated it is '0' and you can just return. If it only has +to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both +update and draw your widget. The reason for separating is to only draw and +update what is actually necessary which is crucial for performance. +Draw List +The optional vertex buffer draw list provides a 2D drawing context +with antialiasing functionality which takes basic filled or outlined shapes +or a path and outputs vertexes, elements and draw commands. +The actual draw list API is not required to be used directly while using this +library since converting the default library draw command output is done by +just calling `nk_convert` but I decided to still make this library accessible +since it can be useful. + +The draw list is based on a path buffering and polygon and polyline +rendering API which allows a lot of ways to draw 2D content to screen. +In fact it is probably more powerful than needed but allows even more crazy +things than this library provides by default. +### Stack +The style modifier stack can be used to temporarily change a +property inside `nk_style`. For example if you want a special +red button you can temporarily push the old button color onto a stack +draw the button with a red color and then you just pop the old color +back from the stack: + + nk_style_push_style_item(ctx, &ctx->style.button.normal, nk_style_item_color(nk_rgb(255,0,0))); + nk_style_push_style_item(ctx, &ctx->style.button.hover, nk_style_item_color(nk_rgb(255,0,0))); + nk_style_push_style_item(ctx, &ctx->style.button.active, nk_style_item_color(nk_rgb(255,0,0))); + nk_style_push_vec2(ctx, &cx->style.button.padding, nk_vec2(2,2)); + + nk_button(...); + + nk_style_pop_style_item(ctx); + nk_style_pop_style_item(ctx); + nk_style_pop_style_item(ctx); + nk_style_pop_vec2(ctx); + +Nuklear has a stack for style_items, float properties, vector properties, +flags, colors, fonts and for button_behavior. Each has it's own fixed size stack +which can be changed at compile time. +### Math + Since nuklear is supposed to work on all systems providing floating point + math without any dependencies I also had to implement my own math functions + for sqrt, sin and cos. Since the actual highly accurate implementations for + the standard library functions are quite complex and I do not need high + precision for my use cases I use approximations. + Sqrt + ---- + For square root nuklear uses the famous fast inverse square root: + https://en.wikipedia.org/wiki/Fast_inverse_square_root with + slightly tweaked magic constant. While on today's hardware it is + probably not faster it is still fast and accurate enough for + nuklear's use cases.

It is probably important to note that the command buffer is the main +/// drawing API and the optional vertex buffer API only takes this format and +/// converts it into a hardware accessible format. +/// +/// To use the command queue to draw your own widgets you can access the +/// command buffer of each window by calling `nk_window_get_canvas` after +/// previously having called `nk_begin`: +/// +/// ```c +/// void draw_red_rectangle_widget(struct nk_context *ctx) +/// { +/// struct nk_command_buffer *canvas; +/// struct nk_input *input = &ctx->input; +/// canvas = nk_window_get_canvas(ctx); +/// +/// struct nk_rect space; +/// enum nk_widget_layout_states state; +/// state = nk_widget(&space, ctx); +/// if (!state) return; +/// +/// if (state != NK_WIDGET_ROM) +/// update_your_widget_by_user_input(...); +/// nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0)); +/// } +/// +/// if (nk_begin(...)) { +/// nk_layout_row_dynamic(ctx, 25, 1); +/// draw_red_rectangle_widget(ctx); +/// } +/// nk_end(..) +/// +/// ``` +/// Important to know if you want to create your own widgets is the `nk_widget` +/// call.

This is being done for padding and rounding, but not border, which is resulting in text being misaligned, most notably when using buttons with thick borders. --- nuklear.h | 4 ++-- src/nuklear_button.c | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/nuklear.h b/nuklear.h index c2edb75..baac97f 100644 --- a/nuklear.h +++ b/nuklear.h @@ -23892,8 +23892,8 @@ nk_do_button(nk_flags *state, struct nk_command_buffer *out, struct nk_rect r, /* calculate button content space */ content->x = r.x + style->padding.x + style->border + style->rounding; content->y = r.y + style->padding.y + style->border + style->rounding; - content->w = r.w - (2 * style->padding.x + style->border + style->rounding*2); - content->h = r.h - (2 * style->padding.y + style->border + style->rounding*2); + content->w = r.w - (2 * (style->padding.x + style->border + style->rounding)); + content->h = r.h - (2 * (style->padding.y + style->border + style->rounding)); /* execute button behavior */ bounds.x = r.x - style->touch_padding.x; diff --git a/src/nuklear_button.c b/src/nuklear_button.c index 2636b60..af80f93 100644 --- a/src/nuklear_button.c +++ b/src/nuklear_button.c @@ -127,8 +127,8 @@ nk_do_button(nk_flags *state, struct nk_command_buffer *out, struct nk_rect r, /* calculate button content space */ content->x = r.x + style->padding.x + style->border + style->rounding; content->y = r.y + style->padding.y + style->border + style->rounding; - content->w = r.w - (2 * style->padding.x + style->border + style->rounding*2); - content->h = r.h - (2 * style->padding.y + style->border + style->rounding*2); + content->w = r.w - (2 * (style->padding.x + style->border + style->rounding)); + content->h = r.h - (2 * (style->padding.y + style->border + style->rounding)); /* execute button behavior */ bounds.x = r.x - style->touch_padding.x; From 42e4c54954c150577fc8e70a26195b2509f67017 Mon Sep 17 00:00:00 2001 From: David Reid Date: Tue, 14 Nov 2023 18:02:22 +1000 Subject: [PATCH 34/64] Bump patch version in clib.json. --- clib.json | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/clib.json b/clib.json index cf690c7..e83c57b 100644 --- a/clib.json +++ b/clib.json @@ -1,6 +1,6 @@ { "name": "nuklear", - "version": "4.10.6", + "version": "4.10.7", "repo": "Immediate-Mode-UI/Nuklear", "description": "A small ANSI C gui toolkit", "keywords": ["gl", "ui", "toolkit"], From d09ff8935e787dc6afc91b6c889194bdc65b2b81 Mon Sep 17 00:00:00 2001 From: Cameron Cawley Date: Thu, 16 Nov 2023 17:01:56 +0000 Subject: [PATCH 35/64] Update to a newer version of stb_image --- demo/common/filebrowser/stb_image.h | 3354 +++++++++++++++++++-------- 1 file changed, 2416 insertions(+), 938 deletions(-) diff --git a/demo/common/filebrowser/stb_image.h b/demo/common/filebrowser/stb_image.h index 1f4d468..5e807a0 100644 --- a/demo/common/filebrowser/stb_image.h +++ b/demo/common/filebrowser/stb_image.h @@ -1,5 +1,5 @@ -/* stb_image - v2.08 - public domain image loader - http://nothings.org/stb_image.h - no warranty implied; use at your own risk +/* stb_image - v2.28 - public domain image loader - http://nothings.org/stb + no warranty implied; use at your own risk Do this: #define STB_IMAGE_IMPLEMENTATION @@ -21,7 +21,7 @@ avoid problematic images and only need the trivial interface JPEG baseline & progressive (12 bpc/arithmetic not supported, same as stock IJG lib) - PNG 1/2/4/8-bit-per-channel (16 bpc not supported) + PNG 1/2/4/8/16-bit-per-channel TGA (not sure what subset, if a subset) BMP non-1bpp, non-RLE @@ -42,184 +42,86 @@ Full documentation under "DOCUMENTATION" below. - Revision 2.00 release notes: +LICENSE - - Progressive JPEG is now supported. + See end of file for license information. - - PPM and PGM binary formats are now supported, thanks to Ken Miller. +RECENT REVISION HISTORY: - - x86 platforms now make use of SSE2 SIMD instructions for - JPEG decoding, and ARM platforms can use NEON SIMD if requested. - This work was done by Fabian "ryg" Giesen. SSE2 is used by - default, but NEON must be enabled explicitly; see docs. - - With other JPEG optimizations included in this version, we see - 2x speedup on a JPEG on an x86 machine, and a 1.5x speedup - on a JPEG on an ARM machine, relative to previous versions of this - library. The same results will not obtain for all JPGs and for all - x86/ARM machines. (Note that progressive JPEGs are significantly - slower to decode than regular JPEGs.) This doesn't mean that this - is the fastest JPEG decoder in the land; rather, it brings it - closer to parity with standard libraries. If you want the fastest - decode, look elsewhere. (See "Philosophy" section of docs below.) - - See final bullet items below for more info on SIMD. - - - Added STBI_MALLOC, STBI_REALLOC, and STBI_FREE macros for replacing - the memory allocator. Unlike other STBI libraries, these macros don't - support a context parameter, so if you need to pass a context in to - the allocator, you'll have to store it in a global or a thread-local - variable. - - - Split existing STBI_NO_HDR flag into two flags, STBI_NO_HDR and - STBI_NO_LINEAR. - STBI_NO_HDR: suppress implementation of .hdr reader format - STBI_NO_LINEAR: suppress high-dynamic-range light-linear float API - - - You can suppress implementation of any of the decoders to reduce - your code footprint by #defining one or more of the following - symbols before creating the implementation. - - STBI_NO_JPEG - STBI_NO_PNG - STBI_NO_BMP - STBI_NO_PSD - STBI_NO_TGA - STBI_NO_GIF - STBI_NO_HDR - STBI_NO_PIC - STBI_NO_PNM (.ppm and .pgm) - - - You can request *only* certain decoders and suppress all other ones - (this will be more forward-compatible, as addition of new decoders - doesn't require you to disable them explicitly): - - STBI_ONLY_JPEG - STBI_ONLY_PNG - STBI_ONLY_BMP - STBI_ONLY_PSD - STBI_ONLY_TGA - STBI_ONLY_GIF - STBI_ONLY_HDR - STBI_ONLY_PIC - STBI_ONLY_PNM (.ppm and .pgm) - - Note that you can define multiples of these, and you will get all - of them ("only x" and "only y" is interpreted to mean "only x&y"). - - - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still - want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB - - - Compilation of all SIMD code can be suppressed with - #define STBI_NO_SIMD - It should not be necessary to disable SIMD unless you have issues - compiling (e.g. using an x86 compiler which doesn't support SSE - intrinsics or that doesn't support the method used to detect - SSE2 support at run-time), and even those can be reported as - bugs so I can refine the built-in compile-time checking to be - smarter. - - - The old STBI_SIMD system which allowed installing a user-defined - IDCT etc. has been removed.

(This is due to using less - integer precision in SIMD.) The C code has been adjusted so - that the same RGB values will be computed regardless of whether - SIMD support is available, so your app should always produce - consistent results. But these results are slightly different from - previous versions. (Specifically, about 3% of available YCbCr values - will compute different RGB results from pre-1.49 versions by +-1; - most of the deviating values are one smaller in the G channel.) - - - If you must produce consistent results with previous versions of - stb_image, #define STBI_JPEG_OLD and you will get the same results - you used to; however, you will not get the SIMD speedups for - the YCbCr-to-RGB conversion step (although you should still see - significant JPEG speedup from the other changes). - - Please note that STBI_JPEG_OLD is a temporary feature; it will be - removed in future versions of the library.

While things still do function, if you're using `NK_INCLUDE_STANDARD_BOOL`, it breaks compilation. This change fixes the `nk_bool`s to be actual `nk_bool`s. --- demo/common/overview.c | 60 +++++++++++++++++++++--------------------- 1 file changed, 30 insertions(+), 30 deletions(-) diff --git a/demo/common/overview.c b/demo/common/overview.c index 261679c..780c073 100644 --- a/demo/common/overview.c +++ b/demo/common/overview.c @@ -2,13 +2,13 @@ static int overview(struct nk_context *ctx) { /* window flags */ - static int show_menu = nk_true; + static nk_bool show_menu = nk_true; static nk_flags window_flags = NK_WINDOW_TITLE|NK_WINDOW_BORDER|NK_WINDOW_SCALABLE|NK_WINDOW_MOVABLE|NK_WINDOW_MINIMIZABLE; nk_flags actual_window_flags; /* popups */ static enum nk_style_header_align header_align = NK_HEADER_RIGHT; - static int show_app_about = nk_false; + static nk_bool show_app_about = nk_false; ctx->style.window.header.align = header_align; @@ -25,7 +25,7 @@ overview(struct nk_context *ctx) enum menu_states {MENU_DEFAULT, MENU_WINDOWS}; static nk_size mprog = 60; static int mslider = 10; - static int mcheck = nk_true; + static nk_bool mcheck = nk_true; nk_menubar_begin(ctx); /* menu #1 */ @@ -35,7 +35,7 @@ overview(struct nk_context *ctx) { static size_t prog = 40; static int slider = 10; - static int check = nk_true; + static nk_bool check = nk_true; nk_layout_row_dynamic(ctx, 25, 1); if (nk_menu_item_label(ctx, "Hide", NK_TEXT_LEFT)) show_menu = nk_false; @@ -141,10 +141,10 @@ overview(struct nk_context *ctx) if (nk_tree_push(ctx, NK_TREE_TAB, "Widgets", NK_MINIMIZED)) { enum options {A,B,C}; - static int checkbox_left_text_left; - static int checkbox_centered_text_right; - static int checkbox_right_text_right; - static int checkbox_right_text_left; + static nk_bool checkbox_left_text_left; + static nk_bool checkbox_centered_text_right; + static nk_bool checkbox_right_text_right; + static nk_bool checkbox_right_text_left; static int option_left; static int option_right; if (nk_tree_push(ctx, NK_TREE_NODE, "Text", NK_MINIMIZED)) @@ -261,7 +261,7 @@ overview(struct nk_context *ctx) if (nk_tree_push(ctx, NK_TREE_NODE, "Inactive", NK_MINIMIZED)) { - static int inactive = 1; + static nk_bool inactive = 1; nk_layout_row_dynamic(ctx, 30, 1); nk_checkbox_label(ctx, "Inactive", &inactive); @@ -269,7 +269,7 @@ overview(struct nk_context *ctx) if (inactive) { nk_widget_disable_begin(ctx); } - + if (nk_button_label(ctx, "button")) fprintf(stdout, "button pressed\n"); @@ -282,7 +282,7 @@ overview(struct nk_context *ctx) { if (nk_tree_push(ctx, NK_TREE_NODE, "List", NK_MINIMIZED)) { - static int selected[4] = {nk_false, nk_false, nk_true, nk_false}; + static nk_bool selected[4] = {nk_false, nk_false, nk_true, nk_false}; nk_layout_row_static(ctx, 18, 100, 1); nk_selectable_label(ctx, "Selectable", NK_TEXT_LEFT, &selected[0]); nk_selectable_label(ctx, "Selectable", NK_TEXT_LEFT, &selected[1]); @@ -294,7 +294,7 @@ overview(struct nk_context *ctx) if (nk_tree_push(ctx, NK_TREE_NODE, "Grid", NK_MINIMIZED)) { int i; - static int selected[16] = {1,0,0,0, 0,1,0,0, 0,0,1,0, 0,0,0,1}; + static nk_bool selected[16] = {1,0,0,0, 0,1,0,0, 0,0,1,0, 0,0,0,1}; nk_layout_row_static(ctx, 50, 50, 4); for (i = 0; i < 16; ++i) { if (nk_selectable_label(ctx, "Z", NK_TEXT_CENTERED, &selected[i])) { @@ -341,7 +341,7 @@ overview(struct nk_context *ctx) */ static float chart_selection = 8.0f; static int current_weapon = 0; - static int check_values[5]; + static nk_bool check_values[5]; static float position[3]; static struct nk_color combo_color = {130, 50, 50, 255}; static struct nk_colorf combo_color2 = {0.509f, 0.705f, 0.2f, 1.0f}; @@ -602,7 +602,7 @@ overview(struct nk_context *ctx) } nk_tree_pop(ctx); } - + if (nk_tree_push(ctx, NK_TREE_NODE, "Horizontal Rule", NK_MINIMIZED)) { nk_layout_row_dynamic(ctx, 12, 1); @@ -713,8 +713,8 @@ overview(struct nk_context *ctx) if (nk_tree_push(ctx, NK_TREE_TAB, "Popup", NK_MINIMIZED)) { static struct nk_color color = {255,0,0, 255}; - static int select[4]; - static int popup_active; + static nk_bool select[4]; + static nk_bool popup_active; const struct nk_input *in = &ctx->input; struct nk_rect bounds; @@ -883,9 +883,9 @@ overview(struct nk_context *ctx) if (nk_tree_push(ctx, NK_TREE_NODE, "Group", NK_MINIMIZED)) { - static int group_titlebar = nk_false; - static int group_border = nk_true; - static int group_no_scrollbar = nk_false; + static nk_bool group_titlebar = nk_false; + static nk_bool group_border = nk_true; + static nk_bool group_no_scrollbar = nk_false; static int group_width = 320; static int group_height = 200; @@ -911,7 +911,7 @@ overview(struct nk_context *ctx) nk_layout_row_static(ctx, (float)group_height, group_width, 2); if (nk_group_begin(ctx, "Group", group_flags)) { int i = 0; - static int selected[16]; + static nk_bool selected[16]; nk_layout_row_static(ctx, 18, 100, 1); for (i = 0; i < 16; ++i) nk_selectable_label(ctx, (selected[i]) ?
