Mhhh, yes you're right. I am stupid. That code is not mine (it's from
the tutorial, for sample purposes, since my code is much bigger and
unreadable to write here :). 

But replacing text with widget doesn't help :

 sub button_press {
        my ($widget, $event) = @_;
        my $len = $widget->get_length()-1;
#1      $widget->set_point($len);
#2      $widget->set_point($widget->get_point());
#3      $widget->set_point(3);
}

All of them (1,2,3) report "Use of uninitialized value in subroutine
entry at test2.pl line 157" (the line of main Gtk;)

On the other hand, when I do :

sub button_press {
        my ($widget, $event) = @_;
        my $len = $widget->get_length()-1;
        $widget->set_point($len);
        print "done";
}

perl doesn't complain anymore ! But it doesn't "set the point" anyway
(may be I should signal_emit_stop_by_name for that ?).

Getting weirder !

Thanks for your help,

Michel.
