Thanks, Kjell, that's exactly what I need.

Hi,
You mean like
Glib::SignalProxy0
<cid:part1.02010902.04080004@vodafone.co.nz>< void >
signal_selection_changed
<cid:part2.04070909.08080901@vodafone.co.nz> () in the
function list at the reference docs?
<http://developer.gnome.org/gtkmm/3.5/classGtk_1_1FileChooser.html>
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));
