i just spent 2 hours searching for documentation on this...
right now i have a transparent panel background, but the window buttons still have an opaque background when focused. i'd like them to be TOTALLY transparent all the time.
i guess there must be a way of adding some lines to gtkrc-2.0 that achieve that.
also, if someone knows where to find documentation on this - how gtk is being used in xfce, particularly the panel. all i found is -this-.
