SDL_ActiveEvent - Application visibility event structure


typedef struct{ Uint8 type; Uint8 gain; Uint8 state; } SDL_ActiveEvent;


type SDL_ACTIVEEVENT. gain 0 if the event is a loss or 1 if it is a gain. state SDL_APPMOUSEFOCUS if mouse focus was gained or lost, SDL_APPINPUTFOCUS if input focus was gained or lost, or SDL_APPACTIVE if the application was iconified (gain=0) or restored(gain=1).


SDL_ActiveEvent is a member of the SDL_Event union and is used when an event of type SDL_ACTIVEEVENT is reported. When the mouse leaves or enters the window area a SDL_APPMOUSEFOCUS type activation event occurs, if the mouse entered the window then gain will be 1, otherwise gain will be 0. A SDL_APPINPUTFOCUS type activa- tion event occurs when the application loses or gains keyboard focus. This usually occurs when another application is made active. Finally, a SDL_APPACTIVE type event occurs when the application is either min- imised/iconified (gain=0) or restored. Note: This event does not occur when an application window is first created.
