I have this loop. As it adds labels into a Pane, it binds <1> and <Double-1> to perform specific tasks.

my @items;
for my $text ( qw( one two three four five six seven eight nine ten ) 
+) {
    my $label = $pane->Label( -text => $text,
        -anchor => 'w',
        -fg => '#000000', 
        -bg => '#C0C0C0',
        -font => 'courier 20 normal',
        )->pack(-fill => 'x', -expand => 1);
    push @items, $label;
    $label->bind('<Button-1>' => sub {
        $_->configure( -bg => '#C0C0C0') for @items;    #unhighlight e
+verything
        $selectedtext = $text;
        $label->configure( -bg=>'#CCE8FF');        #highlight this
        } );
    $label->bind('<Double-1>' => sub {
                if (${$label->cget("-font")} eq 'courier 20 normal') {
                    $label->configure( -font => 'courier 20 bold', -fg
+=>'#0000FF');
                } else {
                    $label->configure( -font => 'courier 20 normal', -
+fg=>"black");
                }
            } 
        );
}

My problem is that, I want to put that whole loop into a function because it will be performed by different parts of the script.

my @items;
InitializeList();
sub InitializeList {
    undef @items;
    for my $text ( qw( one two three four five six seven eight nine te
+n ) ) {
            ...
    }
}

But doing so, those Bindings dont work anymore.


Moreso, I also want to isolate the bindings into separate subroutine on their own as well to compartmentalize everything for ease of maintenance:

sub BindButton1 {
}
sub BindDouble1 {
}

It appears I am having parameter passing problem.

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
