How do I a signal a callback when a gtk.Paned widget handle is dragged?
The gtk.Paned widget provides a ‘move-handle’ signal that would seem to be appropriate, but Skip Montanaro points out that the ‘move-handle’ signal is only emitted when the handle is moved by use of the keyboard. If the paned window handle is dragged using the mouse, the signal is not emitted. John Finlay suggests a good solution: Connect to the ‘notify’ signal and watch for changes in the ‘position’ property of the paned window. The ‘notify’ signal will be emitted when any property of a GObject changes.
