true/false or TRUE/FALSE to prepare for the new boolean type and constants being added to Python. Added code to wx.py to test for the existence of the new constants and to create suitable values if not present. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/WX_2_4_BRANCH@19335 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

# 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

|
# 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
