Re: NSView behaves different on 10.4 vs 10.5?
Hey Kyle, Thanks for the suggestion. Can you tell me more about this idea. It doesn't look like I can set an NSButton's NSButtonCell and NSButtonCell isn't a child of NSView so I can't draw it directly as a sub view. Once I have my sub class of NSButtonCell how do I render into onto the screen.

I'd recommend abstracting out the card-drawing code into a subclass of NSButtonCell and using that cell to draw the hand inside an NSView subclass. Then you don't have to worry about sibling view clipping issues, and you minimize the number of views you have to boot. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Using a separate view for each card is a bad idea anyway. Instead, just use a custom object and get the main view to draw each one. I recall seeing some Apple sample code that implements a variety of card games in a very adaptable way, and also does lots of cool animation. That would probably be a great base for a game like this.
