Hi,

I am currently building a GUI in which I want to elaborate each menu item in a seperate module. This is a fragment of my main program:

use Tk 800;
use Tk::Dialog;
use event;
use icit_messages;

$top = new MainWindow;
$top->title("As2Con Gui"); 
my $frame = $top->Frame(qw/-width 800 -height 300 -background white/)-
+>pack; 

create_gui();
sub create_gui {
    $menubar = $top->Menu;
    $status_menu->command(-label => "~Events",  -command => sub { even
+t_function(\$frame) });
    $status_menu->command(-label => "M~essages",   -command => sub { m
+essages_function(\$frame) });

....

In module event.pm the function event_function is defined (a fragment):

sub event_function
{
    my $top = shift;    
    if ($view)
        {
            $view->packForget
        }    
        
        $view = $$top->Frame(qw/-width 800 -height 400 -background whi
+te/)->pack(-expand => 1, -fill => 'both');

In module icit_messages.pm the function messages_function is defined (a fragment):

sub messages_function
{
   my $top = shift;
   if ($view)
    {
      $view->packForget;
    }    
  $view = $$top->Frame(qw/-width 400 -height 400 -background white/)->
+pack();
...

The problem is when I select menu item Events everything goes OK in the current window, but when I select menu item Messages after I have selected Events the current window is enlarged and the output of Messages is below the output of Events in the same window. This problem does not occur when I select Messages or Events two times after each other...

What am I doing wrong?

Thanks,
Ton
