Sylvain 2019-04-18 21:22:59 UTC Changes: - SDL_WINDOWEVENT_FOCUS_GAINED and SDL_WINDOWEVENT_FOCUS_LOST are sent when the java method onWindowFocusChanged() is called. - If we have support for MultiWindow (eg API >= 24), SDL event loop is blocked/un-blocked (or simply egl-backed-up or not), when java onStart()/onStop() are called. - If not, this behaves like now, SDL event loop is blocked/un-blocked when onPause()/onResume() are called. So if we have two app on screen and switch from one to the other, only FOCUS events are sent (and onPause()/onResume() are called but empty. onStart()/onStop() are not called). The SDL app, un-focused, would still continue to run and display frames (currently the App would be displayed, but paused). Like a video player app or a chronometer that would still be refreshed, even if the window hasn't the focus. It should work also on ChromeBooks (not tested), with two apps opened at the same time. I am not sure this fix Dan's issue. Because focus lost event triggers Minimize function (which BTW is not provided on android). https://hg.libsdl.org/SDL/file/bb41b3635c34/src/video/SDL_video.c#l2653 https://hg.libsdl.org/SDL/file/bb41b3635c34/src/video/SDL_video.c#l2634 So, in addition, it would need to add by default SDL_HINT_VIDEO_MINIMIZE_ON_FOCUS_LOSS to 0. So that the lost focus event doesn't try to minimize the window. And this should fix also the issue. |
