[Dobai-Pataky B. <dp...@gm...>]

|Gdk.pointer_grab(window, owner_events, event_mask, confine_to, cursor, 
time)| <http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gdk#Gdk.pointer_grab>
window: the Gdk::Window 
<http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gdk%3A%3AWindow> which will 
own the grab (the grab window).
this is my problem, i don't know how to find the popup window object

i'd need somethinke like: Gtk::ComboBox.popup_window to be of class 
Gtk::Window
