Gtk::MessageDialog presents a dialog with an image representing the type of message (Error, Question, etc.) alongside some message text. It's simply a convenience widget; you could construct the equivalent of Gtk::MessageDialog from Gtk::Dialog without too much effort, but Gtk::MessageDialog saves typing.
