I bumped up against this problem a couple weeks ago, posted a note about it on the pygtk list, but got no useful workaround suggestions, then ignored it for awhile. Now I'm back to it. There appears to be no useful signal emitted when a GtkPaned widget's handle is moved using the mouse. The move-handle signal seems like the perfect candidate, but the pygtk docs indicate it's only emitted when the handle is moved using a variety of keys (The GTK reference manual is silent on the conditions for the emission of the move-handle signal. This seems like a documentation bug to me.) Quoting from: http://www.moeraki.com/pygtkreference/pygtk2reference/class-gtkpaned.html we find: The "move-handle" signal is emitted when paned has the focus and one of the following key combinations is pressed to move the separator: Left Arrow Right Arrow Up Arrow Down Arrow Page Up Page Down Home End Is there a way to be notified when the handle is moved using the mouse?
