PyGTK Notebook button_press_event connection

[Luigi]

Hi all!

I have an application that uses a gtk.Notebook to show the content of a
GUI. Each page of it has a gtk.Label with a text that explains the
content. Each page is added to the notebook with the method
append_page(chi ld, tab_label=None) , passing a gtk.Label instance as
tab_label variable.

Now I'd like to connect to the button_press_ev ent of the gtk.Label a
function call. I've done something like this:

<code>

notebook = gtk.Notebook()
....
child = gtk.Frame()
....
label = gtk.Label('Any text')
label.connect(' button_press_ev ent', a_function)
....
notebook.append _page(child, label)

</code>

But the button_press_ev ent event is not intercepted (nothing happens
when I click on the tab label).

Any idea to solve this question?

Thanks

Luigi

A gtk.Label does not have a gdk window (as in the windowing system of gtk+),
so it cannot listen to events. A workaround is to put it in an eventbox:

eventbox = gtk.EventBox()
eventbox.set_ev ents(gtk.gdk.BU TTON_PRESS_MASK )
eventbox.connec t('button-press-event', callback)

label = gtk.Label()
eventbox.add(la bel)

notebook.append _page(..., eventbox)

Perhaps you should subscribe to the PyGTK mailing list[1] though, where this
kind of question is more appropriately asked
