I'm getting some weirdness with NSViews and subviews. Here's a

Check out the box around the button that says `Finish'. That border
draws when I press the button, and it refuses to go away. The
button's superview, is the box with the 1.5 pixel-thick border,
which I draw with an `NSBezierPath' in the `drawRect' method. I've
run into this type of thing before, and putting a `[view
setNeedsDisplay:YES]' in the right place does the trick. But in
this case, it's not working.

Why are the subviews apparently using the superview's `drawRect'
method when they're dirty?

More to the point: Does the box drawRect: stroke the framing
rectangle based on the NSRect passed to it? So that when the button
region is dirty it frames the button?

I'm not sure of the "why," but I have encountered this as well.

I've been able to work around it by drawing the border using [self
bounds] rather than the rect variable that drawRect: gets passed.

Here's the code for the `drawRect' method.

Should I be stroking `bounds' and not `rect'?

If you want to draw your bounds, yes.

The rect you are passed is the aggregate dirty rect, not your bounds.
