[pygtk] Tooltips on comboBox

[Alessandro Dentella]

I forward here the answer from Kristian Rietveld in gtk list. I thinks it may
be useful to others.

After this I decided to use deprecated widget OptionMenu, that gives a
normal MenuItem that supports tooltips

This is also because GTK+ hides a tooltip as soon as something is
clicked to avoid the tooltip getting in your way.

Yes, the popup is a different widget.  There is no API call to access
this popup widget directly (this has also been done deliberately,
since the popup widget/window can change when the theme changes and in
general people shouldn't mess around with it ;).

Right now I don't see a way how to easily set a tooltip on the combo
box popup.  I do agree that this would be very useful to be able to do
and we should support this in a future version of GTK+.

I have this mail thread marked in my inbox so that I won't forget to
open a bug for this issue ;)

I think the option menu will give you this opportunity since you have
to create the menu that is popped up yourself and pass that to the
GtkOptionMenu.
