# 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
