Hello, I made a small mistake in creating the columns. I have corrected that. Now I want to delete a particular column upon a press of a button on the window. Please see the attached code below.

/usr/bin/perl use Tk; require "/home/kumar/personal/tk_perl/"; require "/home/kumar/personal/tk_perl/"; my $mw = MainWindow->new(); my $frame = $mw->Frame()->pack(); my $tree = $frame->Scrolled( 'MTree', -height => 20, -width => 50, -columns => 4, -itemtype => 'text', -header => 'true', ); $tree->add(ROOT_ITEM_PATH, -itemtype => 'text', -text => 'Jobs for tes +t'); $tree->header('create', 0 , -itemtype => 'text',-text => 'Cells',); $tree->pack; $tree->header('create', 1 , -text => 'ID'); $tree->header('create', 2 , -text => 'State'); $frame->Button(-text => 'Delete col', -command => sub { $tree->header( +'delete',2,-text=> 'State');})->pack; MainLoop;

      Should cpanminus be part of the standard Perl release?
