i am trying to obtain key events sent to my window and I have been successful. By subclassing General/NSWindow etc.

However, within the class I am trying to catch the up and and down arrow keys but it doesn’t work. Can somone please look at the code below to see what’s wrong? Thanks a lot.

This works

• (void)keyDown: (General/NSEvent *) event { General/NSString *input = [event characters]; if([input isEqual: @”\t”]) { General/NSLog(@”Tab pressed”); return; } }

But this doesn’t and I get a warning. I understand that General/NSUpArrowFunctionKey is an integer, but how do I actually compare it. General/RealControl.m:27: warning: comparison between pointer and integer

• (void)keyDown: (General/NSEvent *) event { if([event characters] == General/NSUpArrowFunctionKey) { General/NSLog(@”Up Arrow pressed”); return; } }

Neither does this work, and I get no warnings or errors �

• (void)keyDown: (General/NSEvent *) event { if([event keyCode] == General/NSUpArrowFunctionKey) { General/NSLog(@”Up arrow pressed”); return; } }

Can someone please tell me what’s wrong? Thanks again.

Try General/ArrowKeyForKeyEquivalent, and then do a little digging, since that page deals only with left and right. The others should be close at hand.

Try if (General/event characters] characterAtIndex:0] == [[NSUpArrowFunctionKey)

I see this a lot, even an Apple guy posted this, but it is broken! It will throw an exception if the event contain no characters, and some key events do!

This should work too.

• (void)keyDown:(General/NSEvent *)event { General/NSString *input = [event characters];

  if([input isEqual:General/[NSString stringWithFormat:@”%C”, General/NSUpArrowFunctionKey]]) { General/NSLog(@”Up Arrow pressed”); return; } }

What if two keys are pressed at once?

Then you should figure out what logically makes sense in your situation. :-)
