Transparency in NSButtonCell


  • Subject: Transparency in NSButtonCell

I am currently working on an NSButton and NSButtonCell subclass. The
button that is being created (by compositing several images together)
is partially transparent. Whenever I click on the button, rather than
redrawing the button from scratch, it seems to be layering the
composited images on top of the existing ones. Is there some special
"clear" command that I need to send to the NSButtonCell before it
redraws?
