in thread failed AUTOLOAD widgets when trying to destory widget

pardon the stupid question, but how do you invoke the grid manager for top level windows, I've been tryin to do it like this:
my $frame = $tl->Frame()->pack; my $lab = $tl->Label()->pack; my $ent = $tl->Entry()->pack; my $label = $frame -> Label(-text=>"NQR Reports "); $lab -> grid(-row=>0,-column=>0); $ent -> grid(-row=>0,-column=>1); $label -> grid(-row=>0,-column=>0); $frame -> grid(-row=>2,-column=>1,-columnspan=>2); my $but1 = $tl->Button( -text => 'Open File1', -command => $push_butt +on2 )->pack; $but1 -> grid(-row=>2,-column=>2,-columnspan=>2);

The code starts executing but the top level window is never created and the system jus hangs .. Any suggestions ??

    As far as I know, you can't mix pack and grid. First you pack() your widgets, then you try to use grid() on them, you can't. See Geometry Management

    Here is a simple grid usage:

    #!/usr/bin/perl use warnings; use strict; use Tk; use Data::Dumper; my $top = new MainWindow(); #my %items = ( A => [1,1a], B => [2,2a], C => [3,3a] ); my $count = 0; my %items = (); for('A'..'Z','a'..'z'){ $count++; $items{$_} = [$count, "$count-a"]; } my $row = 0; foreach my $item ( sort keys(%items) ) { #print @{$items{$item}},"\n"; $top->Label( -text => $item, -anchor => "w", -relief => 'solid', #will show gridlines )->grid( -row => $row, -column => 0 ); $top->Entry( -textvariable => \$items{$item}[0], -width => 5, -relief => 'solid', #will show gridlines )->grid( -row => $row, -column => 1 ); $top->Entry( -textvariable => \$items{$item}[1], -width => 5, -relief => 'solid', #will show gridlines )->grid( -row => $row, -column => 2 ); $row++; } MainLoop();

    I'm not really a human, but I play one on earth.

[stevieb]: I think that placing the * in C when dealing with pointers is akin to keeping separated the circumfix op from the inner ref in Perl: @{ $aref };, which is all personal preference. In perl, I'm good. C, don't know what I like
