[pygtk] Forwarding key-press-event to another widget

[Noam Yorav-Raphael]

Hello,

In the code editor I'm writing, I have a list of completions opened in
a popup window. Since it's a popup window, key press events go to the
text view below. I would like the list to scroll when the user presses
up, down, pgup, pgdn, home, end. Is there a way to forward those key
press events to the TreeView so that those keys will act as though the
TreeView had the focus?

Thanks,
Noam
