Fullscreen Key Down Actions

Question

Hi Everyone:

I am making a test fullscreen application using this guide: http://www.cocoadevcentral.com/articles/000028.php. However, I am running into a problem when I want to get key input. For some reason, it seems that when you set the NSPanel to take up the screen, you also loose the ability for it to get the key down events. I tried to make a button trigger when the user types "s", which works fine in a regular panel, but doesn't seem to work when this change is applied.

Thanks for any help.

Answer 1

when in fullscreen mode ... the keyboard events cannot be captured.

im talking this in context with flash player's fullscreen.

donno abt other players.

Answer 2

It is possible to achieve. Make sure your subclassing NSPanel's (is there a reason why your not using a window?) -canBecomeKeyWindow, and both the panel and it's contentView's -acceptsFirstResponder methods to return TRUE.

Another lower level approach you could try if your designing an app that's using non standard UI (like a game), is to subclass NSApplication's -sendEvent method. Mine looks like:

• (void)sendEvent:(NSEvent *)event { id delegate = [self delegate];

  if(([event type] != NSAppKitDefined) && [delegate shouldHandleEvents] && [delegate respondsToSelector:@selector(handleEvent:)]) [delegate handleEvent:event]; else [super sendEvent:event];
  }
