Hmm, well, that's not quite how I would describe the code. It's
more GtkButton that keeps propagation from happening. But yes,
the end effect is the same. There is no way of getting these
events in the public API.
Suggestions:
1) You can access column->button directly and connect to
::event or ::button-press-event on that. But that is *not*
public API and if it breaks in GTK+-2.6 you and your
users get both pieces.
2) Do something else in your interface, submit a bug asking for
a ::popup-menu signal to be added to GtkTreeViewColumn.
I would suggest 2).
