Bug 516

Summary: SDL_EnableUNICODE + SDL_ENABLEAPPEVENTS produce extra system beeps

Description Marc S. Ressl 2007-11-15 20:47:50 UTC 
I am writing an SDL program which should be portable (that's why I use SDL), but features a customized Cocoa userinterface that uses CMD key shortcuts.

I need to enable SDL_ENABLEAPPEVENTS and SDL_EnableUNICODE. When I do so, application events (triggered with the CMD key) perform their action, but a system beep is also heard.

I found the bug in /src/video/quartz/SDL_QuartzEvents.m. There is an (apparently to me) unnecessary call to interpretKeyEvents:.

The solution would be to remove this call:

    if (SDL_TranslateUNICODE && state == SDL_PRESSED) {
//        [field_edit interpretKeyEvents:[NSArray arrayWithObject:event]];
        chars = [ event characters ];

Thanks
