问题
When I run a fullscreen window (C++ with SDL using the SDL_FULLSCREEN flag), alt-tab has no effect. Researching it, I only found posts of people having problems with it. Is there a way to do it consistently across different machines? (I'm running Ubuntu now, but I'd like portability) Does OpenGL handle this better? (considering switching)
回答1:
SDL likes to XGrabKeyboard() when fullscreened on X11. This tends to lock out your window manager's hotkeys.
Fix SDL or fix your window manager.
