Fellow Monks,

I'm trying to build myself a handy little define-the-keyboard-traversal-path method for a Tk-app i'm doing right now that i may call like this:

&defineOrder(\$widget1, \$widget2, \$widget3)

[download]
my first brainstorm produced this: 
sub defineOrder
{
    for (my $i = 0; defined($_[$i+1]); $i++)
    {
        ${$_[$i]}->bind('<Return>', sub { ${$_[$i+1]}->focus } );
    }
    ${$_[0]}->focus;
}

[download]

...which - of course - wont do, because my forgetful, confused program of course doesn't remember what @_ looked like the moment i binded that anon-sub to this event.

so i tried this: (methinks this is ugly)


&defineOrder(qw/$widget1 $lwidget2 $widget3/);

sub defineOrder
{
    for (my $i = 0; defined($_[$i+1]); $i++)
    {
        my $evalString = $_[$i]."->bind( '<Return>', sub { ".$_[$i+1].
+"->focus } );";    
        print "$evalString\n";
        eval $evalString;
        print "$@\n" if $@;
    }
}

...which, in turn, wont do since the widgets seem to be out of scope inside the sub (as they should be).

anybody have an idea what i can do about this?
i'm not really into using $widget->focusNext since i simply don't like the notion of the focusorder being defined by the order i pack-ed or place-ed the widgets.
(or is there any way to re-shuffle the stacking order?)

wanting to see the light of knowledge, but feeling as if he were inside a black hole,
