the delete_event reuires a GdkEvent structure and a return value, but besides
that, people should never call gtk_signal_emit* directly except for
GTK_RUN_ACTION signals.
mihai probably wants to either call gtk_widget_destroy() directly or invoke
his handler of delete_event directly which could fire up a save-before-close
dialog.
