Hi there IS,

This is exactly what I'm looking for, however I can't get it quite 
right.

In my method, hilightColorWithFrame looks like this:

- (NSColor *)highlightColorWithFrame:(NSRect)cellFrame inView:(NSView 
*)controlView
{
   MatrixSubClass *scMatrix = (MatrixSubClass *)controlView;    
   return [scMatrix activeColor];
}

However, when I run this code, I get:

[NSMatrix activeColor]: selector not recognized [self = 0x340c80]

Am I missing something here?

Thanks for your suggestions,
AK
