Hello all.
I'm having trouble figuring out how to catch modifier keys (command/
option/shift/whatever)
My keydown event is like this:
- (BOOL) onKeyDown: (NSEvent *)theEvent
{
NSString *keyString = [theEvent characters];
unichar key = [keyString characterAtIndex:0];
BOOL keyIsHandled = YES;
OSStatus result = noErr;
switch (key) {
case NSUpArrowFunctionKey:
break;
case NSDownArrowFunctionKey:
break;
case NSCarriageReturnCharacter:
case NSEnterCharacter:
break;
case ' ':
break;
case 'A':
break;
case 'E':
break;
default:
keyIsHandled = NO;
break;
}
NSAssert1 (!result, @"key handled was %d", result);
return keyIsHandled;
}
}
I have no trouble getting regular keypresses, and even the function
keys that have values.
But what I can't figure out is how to pickup a key like command-L, or
something more complex command-option-L.
I know these keys are returned, and there's four bytes in the key
event string, but I have no idea how to interpret these codes.
Do I need another function to handle those keys, or is there some
kind of ns values like there is for the arrow keys I can use?
If anyone has some help on this, I'd be forever greatful.
