About Gtk::MessageDialog

["Leonel Salazar Videaux" <lsalazar estudiantes uci cu>]

Hello everyone, I just create a small program and need to show a
message to the user, all is fine untill I saw that my program shows
the dialog, but not close it by the Gtk::BUTTONS_OK, only pressing
Close in the title bar, what can I do for see the OK button closing
the MessageDialog ?
