-# button colour will change to new colour
-# GetColour method to get the selected colour
-
-# Updates:
-# call back to function if changes made
-
-# Cliff Wells, logiplexsoftware@earthlink.net:
-# - Made ColourSelect into "is a button" rather than "has a button"
-# - Added label parameter and logic to adjust the label colour according to the background
-# colour
-# - Added id argument
-# - Rearranged arguments to more closely follow wx conventions
-# - Simplified some of the code
-
-# Cliff Wells, 2002/02/07
-# - Added ColourSelect Event
-
-# 12/01/2003 - Jeff Grimmett (grimmtooth@softhome.net)
