typeSDL_ACTIVEEVENT.
gain0 if the event is a loss or 1 if it is a gain.
stateSDL_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
activation 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 minimised/iconified (gain=0) or restored.
Note This event does not occur when an application window is first created.
