+/* ============================================================================= + * + * LAYOUT + * + * ============================================================================= */ +/* 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 methodes 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 acually define a layout you just call the appropriate layouting function + * and each subsequnetial 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: + * + * 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. + * + * 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. + * + * 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. + * + * 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. + * + * 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 static widget size specifier 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 + * minumum widget size but it also can grow if more space is available not taken + * by other widgets. Finally there are dynamic widgets which are completly flexible + * and unlike variable widgets can even shrink to zero if not enough space + * is provided. + * + * 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); + * + * 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 alloated space or + * allocated space local position and pixel size. Since this API is quite + * powerfull there are a number of utility functions to get the available space + * and convert between local allocated space and screen space. + * + * 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 + * ------------------- + * nk_layout_set_min_row_height - set the currently used minimum row height to a specified value + * nk_layout_reset_min_row_height - resets the currently used minimum row height to font height + * + * nk_layout_widget_bounds - calculates current width a static layout row can fit inside a window + * nk_layout_ratio_from_pixel - utility functions to calculate window ratio from pixel size + * + * nk_layout_row_dynamic - current layout is divided into n same sized gowing columns + * nk_layout_row_static - current layout is divided into n same fixed sized columns + * nk_layout_row_begin - starts a new row with given height and number of columns + * nk_layout_row_push - pushes another column with given size or window ratio + * nk_layout_row_end - finished previously started row + * nk_layout_row - specifies row columns in array as either window ratio or size + * + * nk_layout_row_template_begin - begins the row template declaration + * nk_layout_row_template_push_dynamic - adds a dynamic column that dynamically grows and can go to zero if not enough space + * nk_layout_row_template_push_variable - adds a variable column that dynamically grows but does not shrink below specified pixel width + * nk_layout_row_template_push_static - adds a static column that does not grow and will always have the same size + * nk_layout_row_template_end - marks the end of the row template + * + * nk_layout_space_begin - begins a new layouting space that allows to specify each widgets position and size + * nk_layout_space_push - pushes position and size of the next widget in own coordiante space either as pixel or ratio + * nk_layout_space_end - marks the end of the layouting space + * + * nk_layout_space_bounds - callable after nk_layout_space_begin and returns total space allocated + * nk_layout_space_to_screen - convertes vector from nk_layout_space coordiant space into screen space + * nk_layout_space_to_local - convertes vector from screem space into nk_layout_space coordinates + * nk_layout_space_rect_to_screen - convertes rectangle from nk_layout_space coordiant space into screen space + * nk_layout_space_rect_to_local - convertes rectangle from screem space into nk_layout_space coordinates + */ +/* nk_layout_set_min_row_height - sets the currently used minimum row height. + * IMPORTANT: The passed height needs to include both your prefered row height + * as well as padding.
