I find that I can draw in color if I do, for example,
gw = widget.get_parent_window()
cmap = widget.get_colormap()
color = cmap.alloc("#FF9999")
gc = gw.new_gc()
gc.foreground = color
widget.draw_arc(gc,
fill, x, y,
r1, r2,
0,360*64)
time.sleep(.001)
return TRUE
But I am not having trouble with an RGB
color = cmap.alloc(0.1,0.2,0.4)
or
color = cmap.alloc(100,300,1000)
both result in back arcs. So if someone could advise me further, I
would be much obliged.
Thanks!
