[pygtk] Strange change in event behavior in PyGTK2

While porting Sketch to PyGTK2 I came across a strange change in the behavior of event objects in PyGTK2. The sample program below connects to the button press, motion and release events and stores the event object of the button_press event in an instance variable. In the motion event handler the

Re: [pygtk] help understanding event loop

s important to connect to the destroy signal of the dialog so you can set the variable to None. This approach has the advantage that you can bind the same callback to several widgets, e.g. a button and a menu item, at once and the function doesn't even have to know to which widget

ressed. IMO, if you already use Python, it makes more sense to implement mechanisms like this in Python than going through GTK. If you already have Sketch, it's in Sketch/Base/connector.py. If there's enough interest, I can make it available separately and write up some documentation. -- B
