The ::populate-popup signal gets emitted before showing the
context menu of the entry.
If you need to add items to the context menu, connect
to this signal and append your items to the @widget, which
will be a #GtkMenu in this case.
If #GtkEntry:populate-all is %TRUE, this signal will
also be emitted to populate touch popups. In this case,
@widget will be a different container, e.g. a #GtkToolbar.
The signal handler should not make assumptions about the
type of @widget.
