DESCRIPTIONSDL_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.
This event does not occur when an application window is first
