I have a program in which I want to change the cursor when the user points at a button. I assume that this can be accomplished by using mouseEntered and mouseExited in NSButtonCell. How do I go about this?
Isaiah,
This is the kind of thing that's typically done with a tracking rectangle. Have a look at the documentation for NSView's -addTrackingRect:owner:userData:assumeInside: and - removeTrackingRect: methods.

jcr, That's very nice. Are there some similar methods in NSButton or NSButtonCell, or will I have to make an NSView?

AgentM,

Subclass NSButton and implement those methods.

That won't work (I tried subclassing both NSButton and NSButtonCell)

Thanks,
	Isaiah
