Michael,
By implementing -drawRect: in your view class, you become responsible
for all drawing in that view. The code below doesn't attempt to draw
the text, it only sets a value.
To draw text in the current drawing context, see the -
drawAtPoint:withAttributes: method of NSString for one way to to do so.
I won't go into the intricacies of NSControl and NSCell just yet.

I'm using a CustomView that inherits from NSButton. I have no
problem drawing the graphical representation of the button in the

setTitle does not work with my custom button. Can you point me to
some examples? Here is the code:
#import <Cocoa/Cocoa.h>
@interface TwoStateButton : NSButton
{}
@end
- (void)drawRect:(NSRect)rect
{
// draw initial black button
NSRect bounds = [self bounds];
[[NSColor blackColor] set];
[NSBezierPath fillRect:bounds];
// draw green LED inset in button (grey if not on)
bounds.origin.x += (bounds.size.width * 0.25) / 2;
bounds.origin.y += bounds.size.height * 0.25;
bounds.size.width *= 0.75;
bounds.size.height *= 0.25;
if ( NSOnState == [self state] )
{
[[NSColor greenColor] set];
}
else
{
[[NSColor lightGrayColor] set];
}
[NSBezierPath fillRect:bounds];
[self setTitle:@"NDB"];
}
