laScreen Structure

Structure: laScreen_t

Maintains the layers associated with the screen. Marks the screen as persistent or not, which either destroys the screen when changed or preserves it for future reloading. Allocates and manages the event handling when screen change / show / hide events occur.

typedef struct laScreen_t {
  uint32_t id;
  laString name;
  laBool persistent;
  laScreen_CreateCallback_FnPtr createCB;
  laBool created;
  laLayer* layers[LA_MAX_LAYERS];
  laScreenOrientation orientation;
  laBool mirrored;
  laBool layerSwapSync;
  laScreen_ShowHideCallback_FnPtr showCB;
  laScreen_ShowHideCallback_FnPtr hideCB;
} laScreen;
