| 23 | * # CategoryProperties | ||
| 24 | * | ||
| 25 | * A property is a variable that can be created and retrieved by name at | ||
| 26 | * runtime. | ||
| 27 | * | ||
| 28 | * All properties are part of a property group (SDL_PropertiesID). A property | ||
| 29 | * group can be created with the SDL_CreateProperties function and destroyed | ||
| 30 | * with the SDL_DestroyProperties function. | ||
| 31 | * | ||
| 32 | * Properties can be added to and retrieved from a property group through the | ||
| 33 | * following functions: | ||
| 34 | * | ||
| 35 | * - SDL_SetPointerProperty and SDL_GetPointerProperty operate on `void*` | ||
| 36 | * pointer types. | ||
| 37 | * - SDL_SetStringProperty and SDL_GetStringProperty operate on string types. | ||
| 38 | * - SDL_SetNumberProperty and SDL_GetNumberProperty operate on signed 64-bit | ||
| 39 | * integer types. | ||
| 40 | * - SDL_SetFloatProperty and SDL_GetFloatProperty operate on floating point | ||
| 41 | * types. | ||
| 42 | * - SDL_SetBooleanProperty and SDL_GetBooleanProperty operate on boolean | ||
| 43 | * types. | ||
| 44 | * | ||
| 45 | * Properties can be removed from a group by using SDL_ClearProperty. | ||
