Re: [pygtk] Change background of selected cell in a TreeView
Thanks! However, the link you sent me explains how to change the
background of cells when they are not selected. At least on my system,
the cells have the same (ubuntu orange) background when selected. I'm
looking for a way to change that color.

Re: [pygtk] GPollFD/GSource wrappers [was: Re: iosource]
I've got it working!
gobject.Source is not functional - you must derive your own class and
define the functions prepare, check and dispatch. See attached example.
If this is actually intended, the error that's being raised should be a
NotImplementedError. Btw, there doesn't seem to be any documentation
around for the GSource/GPollFD wrappers. (Who cares, as long as it works
- and pygobject/pygtk really rocks ;-) )

Martin

I think this explains what you need:

[pygtk] Change background of selected cell in a TreeView
Hello,
TreeViews usually highlight the background of the selected cell. I
would like to change that color to white (the background of unselected
cells), so that a border would be drawn around the cell but its
background won't change.
I tried using treeview.modify_bg(gtk.STATE_SELECTED,
gdk.color_parse('white')), but it had no effect.
Do you have any idea how to do it?
If you are interested, the long story is that I write an IDE - a code
editor which can show a list of completions. If the user requested the
completion list to be shown, pressing enter will copy the selected
item to his text. But the list can also be shown automatically, after
a dot was inserted, and then I don't want Enter to do anything
special, because maybe the user didn't intend to complete from the
list at all. If the user moves around the list to select what he
wants, pressing Enter will of course copy the selected item to the
text. To distinguish between those two states, I would like to use the
selection background.
Thanks,
Noam

[pygtk] gtkunixprint.enumerate_printers - Cant detect all printers.
Hi, I don't if i'm doing this wrong, but I can only get the 'Print To File' gtkunixprint.Printer Listed. Here's a sample code. Even if I return a false from the function, all I get is a loop.
