28 When the mouse leaves or enters the window area a \fBSDL_APPMOUSEFOCUS\fP type activation event occurs, if the mouse entered the window then \fBgain\fR will be 1, otherwise \fBgain\fR will be 0\&. A \fBSDL_APPINPUTFOCUS\fP type activation event occurs when the application loses or gains keyboard focus\&. This usually occurs when another application is made active\&. Finally, a \fBSDL_APPACTIVE\fP type event occurs when the application is either minimised/iconified (\fBgain\fR=0) or restored\&.
