How is it possible to reparent a widget dynamically ?  

I tryed XReparentWindow(XtDisplay(w), XtWindow(w), ...) but this seems
like a sneaky thing to to a widget; in fact, a query to XtParent(w)
showed that the widget did not consider its parent changed (of
course). If I XtUnamanageChild(w) I don't get to XtManageChild(w) to a
different parent.

I'm trying to allow a user to move an XmPushButton from one XmForm to
another.  I think that creating and destroying every time could be
expensive, and that managing and unmanaging a widget per form that I
have could also be expensive. What I think I will have to do is to
parent my buttons further back in the instance hierarchy but I will
loose the management that I had from the different forms.

Does this make sense to anyone ?  Any other tricks available ?

Thanks, Paul.
