!!STRUCTURE DEFINITION


typedef struct{
Uint8 type;

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.
