[pygtk] Paned Widget

[Peyman]

Hello

I have a horizontal paned widget (that thing you can drag left and  
right to show more or less of the left/right hand side) and there is a  
drawing area to the right of it. When I move the paned widget, I want  
to somehow signal on_left_drawingarea_expose(...) such that it can  
redraw the da, but I don't know what signal the HPaned widget emits  
when it is moved. I have tried all of the below, but they don't emit  
any signals when the widget is moved

move_handle
accept_position
check_resize

Any help would be appreciated

Cheers
