       SDL_ActiveEvent - Application visibility event structure

STRUCTURE DEFINITION

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

STRUCTURE DATA

       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).

DESCRIPTION

       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.
