Dear monks

I'm struggeling with creating a scrolled listbox in Tk: the code below works, however I'm not able to scroll with the arrow-keys nor with the mouse-wheel. Do I have to bind the events myself and code the related actions? Or am I just missing something?

Thanks for your help! rata

sub selectProjectDialog_newtest { $mw = shift; # store the main window my @project_choices = split(" ","Project1 Project2 Project3 Proje +ct4 Project11 Project12 Project13 Project14 ") ; my $projectSelection_tl= $mw->Toplevel( ); $projectSelection_tl->title("Select the project:"); $projectSelection_tl->Label(-text => 'Select the project Id:', + )->grid(-row => 5, -column => 10, -sticky => "w"); my $scrolled1 = $projectSelection_tl->Scrolled ("Listbox", -scrollbars => "se", -width => 50, -height => 4, -selectmode => "extended") ->grid(-row => 10, -column => 10, -columns +pan => 10, -rowspan => 10); $scrolled1->insert ("end", @project_choices); }
