Re: Solved: Focused UI element, UNSOLVED: widgets don't work properly in a bordrless window?!?

Ondra, I m not sure on this one, but the docs say:

- (BOOL)canBecomeKeyWindow

Returns YES if the receiver can become the key window, NO if it can't.
Attempts to make the receiver the key window are abandoned if this
method returns NO. NSWindow's implementation returns YES if the
receiver has a title bar or a resize bar, NO otherwise.

So I'd guess, it returns NO for a borderless window. If I d take a shot
on this one, I d say you ll have to make it return YES. And here is my
question for you: is it possible to use a category to override a
function? Or do you have to subclass NSWindow?
