Hi all,
I have a subclass of NSImageCell that displays a progress indicator in
addition to images. The problem I'm having is that I have no idea when
the cell is hidden by the outline view, like when the parent item is
collapsed. So I end up with the progress indicator spinning out in
empty space. Is there any way to find out when my cell shouldn't be
drawing?
Thanks,
Glen
