Gtk::FileChooser::signal_selection_changed() is emitted when there is a 
change in the set of selected files, but Phil wants to know when the 
user of his program selects another file filter. I can't find such a 
signal directly in Gtk::FileChooser, but there is the property 
Gtk::FileChooser::property_filter(). Every property has a 
signal_changed() which is emitted when the value of the property 
changes. So I suppose you can use something like

m_FileChooser->property_filter().signal_changed().connect(sigc::mem_fun(*this, 
&MyClass::on_filter_changed));
