You don't. (Unless you want to, of course.) You just call tied()
on the tied array to retrieve the object at a later time, just as
I wrote in my last message:

    tied(@sl)->get_selection->set_mode('multiple');

That would set the associated TreeView's selection mode.

However, I just thought of something else: this couples the
widget and its data store tightly, since from the Perl end of
things, they become one and the same -- and sharing the ListStore
becomes impossible. But the tied interface doesn't necessitate a
coupling with a particular widget; it could be part of the
ListStore class in general, transparent to the TreeView, only
visisble to the Perl programmer as a (big) convenience.

Which would mean that the tied interface would wander over into
Gtk2::ListStore proper. And Gtk2::Ex::Simple::List would be left
as nothing but a thin wrapper that instantiates a ListStore and
TreeView at once and keeps track of both together.

And now I'm not sure what to think anymore. :-)
