19
20 state SDL_APPMOUSEFOCUS if mouse focus was gained or
21 lost, SDL_APPINPUTFOCUS if input focus was gained
22 or lost, or SDL_APPACTIVE if the application was
23 iconified (gain=0) or restored(gain=1).
24
26 SDL_ActiveEvent is a member of the SDL_Event union and is used when an
27 event of type SDL_ACTIVEEVENT is reported.
28
29 When the mouse leaves or enters the window area a SDL_APPMOUSEFOCUS
30 type activation event occurs, if the mouse entered the window then gain
31 will be 1, otherwise gain will be 0. A SDL_APPINPUTFOCUS type activa‐
32 tion event occurs when the application loses or gains keyboard focus.
33 This usually occurs when another application is made active. Finally, a
34 SDL_APPACTIVE type event occurs when the application is either min‐
35 imised/iconified (gain=0) or restored.
36
37 Note:
38
39 This event does not occur when an application window is first
40 created.
