Example #2

File: gx_main.cpp Project: dafx/guitarix

	*(++dynamic_cast<Gtk::HBox*>(
	      *dialog->get_vbox()->get_children().begin())->get_children().begin()));
    // add an alignment parent to the label widget inside the message area
    // should better define our own dialog instead of hacking MessageDialog...
    Gtk::Alignment *align = new Gtk::Alignment();
