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. |

https://www.libsdl.org/
Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting
with README.md
Enjoy!
