Have not tried running your sample code yet, but see what happens if 
you replace the calls to resize() with a call to recalc():

	@inspectordlg.recalc

I see another potential problem with the code, which is that every call 
to ObjectInspector#set adds a new FXMatrix widget to the dialog box 
(@inspectordlg). Unless I'm just misreading things, I suspect that 
you'll want to first remove the old matrix first, i.e.

	def set(newobj)
		@targetObject = newobj

		# Out with the old...
		@propertyFrame.removeChild(@matrix)

		# ... and in with the new.
		@matrix = FXMatrix.new(@propertyFrame, ...)

		# ... complete matrix setup ...		
	end

Hope this helps,
