+
+# creates a colour wxButton with selectable color
+# button click provides a colour selection box
+# 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)
+#
+# o Updated for 2.5 compatability.

+"""
+Provides a `ColourSelect` button that, when clicked, will display a
+colour selection dialog.  The selected colour is displayed on the
+button itself.
