Hello dear Monks,
I'm totally unable to bind the up and down keys to move in
a tk listbox
I found a few examples but none of them worked.
This is a simple test script :
use Tk;
my $mw = MainWindow -> new();
my $lb = $mw -> Scrolled("Listbox",
-scrollbars=>'e' ,
) -> pack(
-side => 'left' ,
-fill => 'y'
);
foreach my $key ("a" , "b" , "c") {
$lb -> insert( 'end', $key );
}
$lb->activate ( 0 ) ;
$lb->selectionSet ( 0 ) ;
$lb -> bind ('<Key-Down>', sub {print "haha\n"} );
$mw -> bind ('<Key-Up>', sub {print "\nblabla"} );
MainLoop;
It seems I have to bind the key to the main window and not to the listbox, is this right ?
Thanks for any help or example.
Have a nice day.
