Re: [gtkmm] focus

[Barnaby Gray <bee pickle me uk>]

The only place I remember having seen the refocusing for invalid input
behaviour is in the gtkcombo widget - looking at the sources for this
in gtk you see they obviously had exactly the same problem, and have
cheated by instead calling the grab_focus in an idle callback they
setup in the focus out handler. So you can achieve the same with
something like:

    Glib::signal_idle().connect(
      SigC::bind_return(
	SigC::slot( m_entry, &Gtk::Entry::grab_focus ), false ) );

But it's a hack.. and didn't really get the results I wanted in the
end - I really need some kind of modal lock on that widget until they
enter valid input..
