Thanks for this "insider tip"! I realised that this might also be a
workaround the problem I had setting tooltips to treeview column headers
(also clist's). I tried it and it was.
Setting the tooltip to the result of a triply nested Get_Parent call on
the label does the trick. The fact that it must be shown and realized
also makes it more cumbersome than the old method with eventboxes though.
The next Gtk version will probably get a new routine for it.
