As you can see in the gdk documentation[1]:
�The GdkGCValues structure holds a set of values used to create or

GdkColor foreground;
the foreground color. Note that
gdk_gc_get_values() only sets the
pixel value.
GdkColor background;
the background color. Note that
gdk_gc_get_values() only sets the
pixel value.�
The note "Note that gdk_gc_get_values() only sets the pixel value."
appears to be missing from the PyGTK documentation. Feel free about
filing a bug report regarding documentation.
Of course it would be way more useful if PyGTK could set the color rgb
values when fetching the gc color.
You can use gtk.gdk.Colormap.query_color to get the RGB values from
the pixel value.

Does anybody know how to get the rgb values from a gtk.gdk.GC?
Attempting to access the values returns garbage, as evidenced by this
example:
Python 2.4 (#1, Mar 9 2005, 09:57:26) [C] on irix6
Type "help", "copyright", "credits" or "license" for more information.
import pygtk
pygtk.require('2.0')
import gtk
widget = gtk.Window()
widget.show()
style = widget.get_style()
gc = style.fg_gc[gtk.STATE_NORMAL]
gc.foreground
<GdkColor at 0x10327ce0>
gc.foreground.red
4107
gc.foreground.green
30416
gc.foreground.blue
0
colormap = widget.get_colormap()
red = colormap.alloc_color(0xFFFF, 0x00, 0x00)
red.red
65535
red.green
0
red.blue
0
gc.foreground = red
gc.foreground.red
4107
gc.foreground.green
30416
gc.foreground.blue
0
The color in the gc draws correctly to the screen. I need the rgb values to
match gtk colors with rendering done by other code.
