replacing widgets in packing boxes

I have some container or other, say a packing vbox, in the
middle of a
huge screen and I have done $vbox->pack_start($widget, 0,
1, 5);

I now want, without rebuilding the whole screen from
scratch, to replace
$widget with another, possibly completely different,
$newwidget.

Is this possible?

I have the reference "$widget" available to me
as well as its parent's.

Dirk

So to answer my own question for now: I create an empty
vbox() and
remember its reference (a palaver in itself) and then remove
any old
widget (maybe none) and (re-)pack_start the new one. The
vbox() will
only have one item in it which will fill it to the maximum
space
allowed.

If you have the child of the vbox, you can avoid keeping the
 
reference tothe vbox itself by doing  $vbox =
$widget->get_parent.   
Depends on how much bookkeeping overhead it is.
