The default widget is the widget that’s activated when the user
presses Enter in a dialog (for example). This function sets or
unsets the default widget for a #GtkWindow. When setting (rather
than unsetting) the default widget it’s generally easier to call
gtk_widget_grab_default() on the widget. Before making a widget
the default widget, you must call gtk_widget_set_can_default() on
the widget you’d like to make the default.
