I tried this already but it has the same behaviour - tooltip is shown
around the corners of a widget only :-(

There exists in the Perl-Gtk2 reference Gtk2::Tooltip
(http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/Tooltip.html)
and a method $tooltip->set_tip_area ($rect) but how can I use this?
There is no method in Gtk2::Widget or elsewhere to get the object to
call this method. Also it doesn't exist directly anywhere.

Could you provide a perl snippet so that I understand what I have to do?

Thanks,
Thomas
