Side issue:
Suggestion to James: make the GDK colormap allocation function accept
floating point values from 0 to 1 as well as 16-bit integers. Or does
it do this already?
The "bg" element is an "array" of five GDKcolors, which have to be
allocated. (style.black is a provided constant, but there is no
style.red.) GDKcolors, in turn, are created per X-window (blargh)
from three 16-bit RGB values.
# set the background style
red = (1,0,0)
for i in range(5):
style.bg[i] = _alloc_color (o.window, red)
# Allocate a GDKcolor from RGB values expressed as numbers
# from 0 to 1.0
def _alloc_color (widget, RGB):
RGB48 = map (lambda f: f * ((1<<16) - 1), RGB)
return apply (widget.get_colormap().alloc, RGB48)
Suggestion to James: provide a variant of alloc() which will accept
floating point values in the interval [0, 1.0] directly.
