[gtkmm] Gtk::TreeStore::signal_rows_reordered() weirdness

[Andrei Yurkevich <urruru ru ru>]

Hi,

I'm having problems with TreeStore::on_rows_reordered callback - I
connect signal_rows_reordered handler, set up my treeview, but the
callback is never called when rows are dragged and replaced:


// in mystore.h:
class MyListStore : public Gtk::ListStore {
public:
  TracksListStore ();
  static Glib::RefPtr<TracksListStore> create();
  virtual void on_rows_reordered (const TreeModel::Path& path,
                                  const TreeModel::iterator& iter,
                                  int* new_order);
  ... more code ...
};


// in mystore.cc:
MyListStore::some_method () {
  ... some code ...
  signal_rows_reordered().connect ( sigc::mem_fun (*this,
                          &MyListStore::on_rows_reordered) );
  ... some more code ...
}

void
MyListStore::on_rows_reordered (const TreeModel::Path& path,
                                const TreeModel::iterator& iter,
                                int* new_order)
{
  do_something();
}

the problem is that program never hits on_rows_reordered() callback...
Does anybody know where my problem is?

cheers,
Andrei
