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.
