Re: Gtk::Expander and the activate signal

[Arne Anka <duckspammer gmail com>]

Hi,

Indeed, my mistake. I got confused by http://www.pygtk.org/pygtk2reference/class-gtkexpander.html#signal-gtkexpander--activate, but obviously the GTK+ docs are a better source of information than the pygtk wrapper.

Thanks for the swift answer.
