Re: [gtk-list] Clists (Feature request)

[Frank v Waveren <fvw var cx>]

I couldn't find the program on your page... Could you send me the program
(would be usefull, as I said, I have no gtk experience), or could somebody
tell me how to make the on_person_selector_list_key_press_event function
the handler for keypresses? Thanks
