lepetitalbert has asked for the wisdom of the Perl Monks concerning the following question:
Hello dear Monks,
I'm totally unable to bind the up and down keys to move in a tk listboxI 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.
