| | 13 | # creates a colour wxButton with selectable color |
| | 14 | # button click provides a colour selection box |
| | 15 | # button colour will change to new colour |
| | 16 | # GetColour method to get the selected colour |
| | 17 | |
| | 18 | # Updates: |
| | 19 | # call back to function if changes made |
| | 20 | |
| | 21 | # Cliff Wells, logiplexsoftware@earthlink.net: |
| | 22 | # - Made ColourSelect into "is a button" rather than "has a button" |
| | 23 | # - Added label parameter and logic to adjust the label colour according to the background |
| | 24 | # colour |
| | 25 | # - Added id argument |
| | 26 | # - Rearranged arguments to more closely follow wx conventions |
| | 27 | # - Simplified some of the code |
| | 28 | |
| | 29 | # Cliff Wells, 2002/02/07 |
| | 30 | # - Added ColourSelect Event |
