Adds an activatable widget to the action area of a #GtkDialog,
connecting a signal handler that will emit the #GtkDialog::response
signal on the dialog when the widget is activated. The widget is
appended to the end of the dialog’s action area. If you want to add a
non-activatable widget, simply pack it into the @action_area field
of the #GtkDialog struct.
