Gtkmm3: Getting a signal when clicking on a row in TreeView

Question

I have this code:

Glib::RefPtr<Gtk::TreeSelection> clSelection = treeview.get_selection();
clSelection.signal_changed().connect( sigc::mem_fun(*this, &MyClass::treeview_clicked) );

And get this error on compile with g++:

‘class Glib::RefPtr<Gtk::TreeSelection>’ has no member named ‘signal_changed’

I've looked everywhere and I don't seem to be missing anything. Why does it say that signal_changed() doesn't exist when it's in the documentation? Is there another way I can go about this?

Answer 1

I believe it should be:

clSelection->signal_changed().connect( sigc::mem_fun(*this, &MyClass::treeview_clicked) );
