I am creating a custom NSButtonCell for a custom rendering.

Now, I want to have different aspect depending if the mouse is over the button or not. How can I get this information?

Thanks and regards,

Here is i have created and worked for me perfectly...

Step 1: Create the Button with tracking area

 NSButton *myButton = [[NSButton alloc] initWithFrame:NSMakeRect(100, 7, 100, 50)]; [myButton setTitle:@"sample"];  [self.window.contentView addSubview:myButton]; // Insert code here to initialize your application NSTrackingArea* trackingArea = [[NSTrackingArea alloc]                                 initWithRect:[myButton bounds]                                 options:NSTrackingMouseEnteredAndExited | NSTrackingActiveAlways                                 owner:self userInfo:nil]; [myButton addTrackingArea:trackingArea]; 

Step: 2 Implement the following methods

- (void)mouseEntered:(NSEvent *)theEvent{ NSLog(@"entered"); [[myButton cell] setBackgroundColor:[NSColor blueColor]];   }  - (void)mouseExited:(NSEvent *)theEvent{ [[myButton cell] setBackgroundColor:[NSColor redColor]]; NSLog(@"exited");  }
