Thanks for your help.
I'm trying to understand how Pygtkmvc connects signals. I have a project called "Sandbox" that I'm developing with GTK3, so I can't use Pygtkmvc. I need to understand how the signals should be connected. Connecting the signals in the view is trivial, so how do I do it in the control module?
