Re: Tk: pack, grid or place?

[milarepa]

I started using pack because in most documentation said it's the simplest geometry manager. Honestly at the beginning I felt like a daunting task, but with practice I managed to produce the results I wanted.
Besides taking care of which side you "stack" your widgets, I found that the most important thing with pack is the order in which you place your widgets. For example, I wanted to put several checkbuttons one after the other horizontally. Then I wanted a button just below these checkbuttons. However, after minutes of trial and error I found that the code for the button should go first than the checkbuttons. Here is a snapshot of the code:

#!/usr/perl/bin/perl

use Tk;
use warnings;
use strict;

my ($search, $mw, $entry, $text, $io, $checks);
my $id = 0;

$mw = MainWindow -> new;
$mw -> title("AIM");
$mw -> bind('<Key-Escape>' => sub {  exit } );

#**************** text *************************
my $scrollbar = $mw->Scrollbar( );
$scrollbar->pack(-side => 'right', -fill => 'y');
$text = $mw -> Text(-font=>"{Verdana} 10 {bold}", -width => 50, -heigh
+t => 25, 
, -yscrollcommand => ['set' => $scrollbar]) -> pack(-side=>'right');
$scrollbar->configure(-command => ['yview' => $text]);

#**************** entry *************************
$entry = $mw -> Entry(-font=>"{Verdana} 10 {bold}", -textvariable => \
+$search) -> pack(-side=>'top');
$entry -> bind('<Key-Return>' => \&search );
$entry -> focus;

#**************** button *************************
my $btn_clip = $mw -> Button(-text=>"Copy to Clipboard", 
                     -command=>sub {$text->clipboardAppend($text->get(
+"1.0", 'end'));})
                     ->pack(-side=>'bottom', -expand=>'1', -anchor=>'n
+w');

#*********** checkbutton *************************
foreach (qw/address telephone keyword all/) {
        $checks = $mw -> Checkbutton( -text => $_) -> pack(-side=>'lef
+t', -anchor=>'n');
}
MainLoop;

Hope this helps...!!!!

For me, I found it easier to get the layout I want by packing groups of things into separate frames, e.g., for the checkboxes, I'd just pack a frame to the top, then pack each checkbox to the left in the frame.

Yes, you are right.
Another way is to group related widgets into frames. That's exactly what I did with LaTeX Wizard 708332. Honestly when I finish it I felt I was depending too much on frames, so on the next project I wanted to rely more on my ability to use the pack geometry manager. Just for practice and fun.... ;-) !!!!
That's how we learn new things.
But Thanks anyway for your comments.
