Eeerr.... I'm confused a bit. As far as I can see documentation
mixes two different meaning of the word "pointer".
1. a variable holding a memory address
2. a small arrow (or other shape) moved by mouse (or other pointing device)

http://gtk2-perl.sourceforge.net/doc/pod/Glib/Object.html writes:

scalar = Glib::Object->new_from_pointer ($pointer, $noinc=FALSE)
        $pointer (unsigned) a C pointer value as an integer.

[...]

gpointer = $object->get_pointer
        Complement of new_from_pointer.

Unfortunately Gtk2::Widget class overrides method get_pointer so
$notebook->get_pointer() returns two small integers,
the actual coordinates of the small arrow within the window.
See
http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/Widget.html#_x_y_widget_get_poin

What is $object in the former doc snippet?
How to get a valid gpointer value?

Any idea how could I force signal handler to be executed without
actual page switch? :-)
Now I have to do some workarounds. The program works but it is not "clean".
