Hi Monks,

I am facing problem in creating combo box widget in child window.

For first time, child window launching correctly and all widgets are placed fine. But for second time, when launching child window it doesn't show the Combo box widget

Kindly point me where is the problem

#!/usr/bin/perl
use Tk;
use Tk::JComboBox;

my $screen_size = "1010x720+0+0";
my $tool_name='Testing Interface';

&Screen();
MainLoop;

#-------Drawing User interface screeen----------------------
sub Screen {
    $main_screen_object = MainWindow->new(-bg => 'white');
    $main_screen_object->geometry($screen_size);
    $main_screen_object->title($tool_name);
    createButton('CREATE NEW WINDOW',15,490,150,$main_screen_object);
}

#-------Callback function 'CREATE NEW WINDOW' button------------------
+------
sub onCREATENEWWINDOWButtonClick {
    $main_screen_object->update();    
    $CopyWindow=$main_screen_object->Toplevel(-height => 240, -width =
+> 270, -background => 'white', -title => 'Copy Mapping') or die "coul
+d not instant\n";
    createLabel('COUNTRY',30,25,undef,undef,undef,$CopyWindow);
    our @CountryCodesList=qw /HD NK ID LK/;
    createComboBox('CountryCodes',10,140,25,$CopyWindow);
}

sub onCountryCodeComboBoxSelect {
}
