My application uses SDL library. For enter to fullscreen mode I use SDL_SetVideoMode and appropriate flag - SDL_FULLSCREEN.

Problem: When application is in fullscreen mode, I can't call "force quit" dialog and switching between other applications. After Cmd+Option+ESQ clicking my application is quit instead of "force quit" dialog is appear. And on Cmd+Tab clicking nothing is happens...

Can anybody help me?

That is the normal behavior for the APIs that SDL is using.

10.5 added a new API (-[NSView enterFullScreenMode:withOptions:] which has slightly different behavior, I think, but SDL is not using it.

Thank you, OneSadCoocie.

Maybe you know any possibilities to achieve this behavior in application based on SDL library?

For "Force Quit" to not just kill your app (not sure why you care), patch SDL (probably hard or impossible) or ditch SDL.

For "Command-Tab", you could handle it yourself and hide your own application, which is not "perfect" but probably good enough. If you insist on seeing the switcher over your app, again, patch SDL or ditch SDL.

Thank you for answering

You can use SetSystemUIMode() to disable force quit and cmd-tab entirely without having to mess with SDL itself, but you'd better be damn sure your app is bulletproof because it will leave you with only a hard reboot to escape your program.

How can I hide my application?

tear down your full-screen window and call [NSApp hide], probably.
