Ah yes I hadn't thought about that...

The only thing I know about it is from the explanation given by Murray
Cummings in the bug report I mentioned.
With connect(), it is first passed to the treeview/renderer (where,
unfortunately, "the standard handler stops the further handling of the
signal", ie it is not delivered in turn to the user's handler), whereas
with connect_notify(), the event is passed to the users's handler first
and then to tthe treeview.
Using connect_notify() ensures the application gets the
button_press_event message.

No problem, I know what it's like :-))

Thanks for your reply.
