laContext_t Structure

Structure: laContext

The context represents an discrete instance of Aria user interface library. The library is designed to be multi-instance and fully re-entrant. The entire state of the library is stored and referenced through the context pointer.

struct laContext_t {
  GFX_Display displayIndex;
  void* gfxContext;
  GFXU_MemoryIntf memIntf;
  laPreemptionLevel preemptLevel;
  laArray screenList;
  laScreen* activeScreen;
  uint32_t frameState;
  uint32_t currentLayer;
  laInputState input;
  GFXU_StringTableAsset* stringTable;
  uint32_t languageID;
  uint32_t widgetIDs;
  laScheme defaultScheme;
  GFX_ColorMode colorMode;
  laWidget* focus;
  laEditWidget* edit;
  laContext_ActiveScreenChangedCallback_FnPtr screenChangedCB;
  laContext_LanguageChangedCallback_FnPtr languageChangedCB;
  laContext_PreprocessAssetsStateChangedCallback_FnPtr preprocessStateChangedCB;
};
