Re: Tab Order for Widgets in HList

Here is a stupid way to do it :)

#!/usr/bin/perl --
use strict;
use warnings;
use Tk;
use Tk::HList;

my $mw = MainWindow->new();

my $hlist = $mw->HList( -header => 0, -columns => 1 )->pack( qw/-expan
+d 1 -fill both /);
                       
$hlist->add(0);
$hlist->itemCreate(0, 0, -itemtype => 'window', -widget => $hlist->Ent
+ry(-text => "Text0") );

$hlist->add(1);
$hlist->itemCreate(1, 0, -itemtype => 'window', -widget => $hlist->Ent
+ry(-text => "Text1") );

$hlist->add(2);
$hlist->itemCreate(2, 0, -itemtype => 'window', -widget => $hlist->Ent
+ry(-text => "Text2") );


$mw -> bind('all','<Tab>', sub {
    no warnings 'uninitialized';
    $hlist->focus;
    my $origSel = $hlist->info('anchor');
    $hlist->UpDown('next');
    my $newSel = $hlist->info('anchor');
    if( ( $origSel and $newSel ) and ( $origSel == $newSel ) ){
        $hlist->selectionClear;
        $hlist->anchorClear;
        $hlist->UpDown('next'); # go back to zero
    }            
    Tk::break();
}); 

MainLoop;

And the smart way `$mw -> bind('all','<Tab>', sub { $Tk::event->W ->focusPrev; Tk::break(); } ); $mw -> bind('all','<Shift-Tab>', sub { $Tk::event->W ->focusNext; Tk::break(); } );` [download]	[reply] [d/l]

Very nice! But, for me, Shift-Tab does not work, I have to specify Shift-ISO_Left_Tab :-(	[reply]

Checking the source for Tk::MainWindow reveals that it uses the virtual `<<LeftTab>>`, so this should work for all, and its even simpler `$mw->bind('all','<Tab>','focusPrev'); $mw->bind('all','<<LeftTab>>','focusNext');` [download]	[reply] [d/l] [select]
