Hi Randy,
	Not directly.  One possibility is to use Pmw.ScrolledFrame (http:// 
pmw.sourceforge.net/doc/ScrolledFrame.html) as the parent widget for  
the contents of your dialog.  Take the frame you get as an arg to the  
fillInUI() method and immediately create a Pmw.ScrolledFrame with  
that frame as the parent.  Then fill your dialog in from the frame  
you get from Pmw.ScrolledFrame.interior().  You can do this almost  
painlessly like so:

	def fillInUI(self, parent):
		sf = Pmw.ScrolledFrame(parent)
		sf.grid(sticky="nsew")
		origParent, parent = parent, sf.interior()
		# remainder of fillInUI() remains the same...

	Another possibility is to use the Feature_Buttons_Panel widget from  
Chimera's CGLtk.Hybrid module.  This is what Volume Viewer uses to  
hide/show sections of its interface.  You'd have to look at the  
Volume Viewer code to see how it's called since I haven't used it  
myself.
