[pygtk] signal_autoconnect not working

[Miguel Ángel García]

Hello.

It is possible you do not added the correct function in your .glade.

You must go to "properties" and select "signals". At the correct signal
you have to set the name. As I see in your code, you'd have to set
"clicked" signal of button to "on_update".

If your widget as no function asigned to a signal, signal_connect is
not going to work.

See you.
