Re: [Pythoncard-users] Color in Lists

[Kevin A. <al...@se...>]

Thanks Daryl,
just as an FYI you don't have to use the Colour class, wxPython will 
accept a variety of formats and convert appropriately. You can use the 
same kind of representations you would in PythonCard.

COLOURS = ['black', '#660000', 'red',
            (255, 0x99, 0), (255, 255, 0), 'green',
            'blue', (0x99, 0xff, 0), '#cccccc', 'white']

is equivelant to

COLOURS = [Colour(0, 0, 0),       Colour(0x66, 0, 0),    Colour(0xff, 
0, 0),
            Colour(0xff, 0x99, 0), Colour(0xff, 0xff, 0), Colour(0, 
0xff, 0),
            Colour(0, 0, 0xff),    Colour(0x99, 0xff, 0), Colour(0xcc, 
0xcc,0xcc),
            Colour(0xff, 0xff, 0xff)]

All of the named colors that wxPython supports as well as their RGB 
values are defined in wx/lib/colourdb.py. The names are not 
case-sensitive.
