Just a note on colour allocation.
Previously, before I had added colourmap support to pygtk, I hada
color_alloc function. As the first argument it took a widget or style or
window, and the other arguments would specify the colour in one of three
ways:
colour = color_alloc(wid, 'red') # allocate red
colour = color_alloc(wid, 0xff0000)
colour = color_alloc(wid, 0xffff, 0, 0) # 16 bit RGB elements
That function is now deprecated. The correct way of allocating colours
for use in text widget or for drawing is to use the GdkColormap type's
alloc method. You can get the colourmap from windows, styles and widgets
as follows:
cmap = style.colormap
cmap = window.colormap
cmap = widget.get_colormap()
And you can allocate colours in two ways:
colour = cmap.alloc('red') # a string name. '#ff0000' would also give red
colour = cmap.alloc(0xffff, 0, 0) # 16 bit RGB elements
It is prefered that you use GdkColormap.alloc instead of color_alloc. I
hope that this is helpful.
