Hi Monk,

Suppose I have a Hlistplus widget with some data in it in some rows and under some column headers. Assume if I want to enter a new set of data in an already existing entryPaths, then how can I do that deleting the existing data in those rows.

while doing that I am getting following error :

XS_Tk__Callback_Call error:element "0" already exists at /user/perl_5.8.8/lib/Tk.pm line 250.
XS_Tk__Callback_Call: Command not found.

I am just copy/pasting a sample code here : 

use Tk;
use HListplus;

my $mw = MainWindow->new();

# CREATE HEADER STYLE 1
my $headerstyle1 = $mw->ItemStyle(
  'window',
  -anchor => 'nw',
  -pady => -10,
  -padx => 10,
);

# CREATE MY HLIST
my $hlist = $mw->Scrolled(
  'HListplus',
  -scrollbars  => 'oe',
  -columns     => 2,
  -header      => 1,
  -width       => 40,
  -headerstyle => $headerstyle1,
)->pack( -side => 'left', -expand => 'yes', -fill => 'both' );

# CREATE HEADER STYLE 2
my $headerstyle = $hlist->ItemStyle(
  'window',
  -anchor => 'nw',
  -pady   => 0,
  -padx   => 10,
);

$hlist->header(
  'create', 0,
  -itemtype         => 'resizebutton',
  -style            => $headerstyle,
  -text             => 'Test Name',
  -activebackground => 'white',
);
$hlist->header(
  'create', 1,
  -itemtype         => 'resizebutton',
  -style            => $headerstyle,
  -text             => 'Status',
  -activebackground => 'white',
);
my $red = $hlist->ItemStyle( 'text', -foreground => '#800000', 
-background => 'white' );
my $blue = $hlist->ItemStyle( 'text', -foreground => '#000080',
-anchor => 'e', -background => 'white' );

foreach ( [ Joe => '$10,000' ], [ Peter => '$20,000' ], [ Raj => '$90,
000 something to make it very much wider' ],
  [ Zinh => '$0' ] )
{
  my $e = $hlist->addchild("");
  $hlist->itemCreate( $e, 0, -itemtype => 'text', -text => $_->[0], -s
+tyle => $red );

  $hlist->itemCreate( $e, 1, -itemtype => 'text', -text => $_->[1], -s
+tyle => $blue );
  $hlist->selectionClear();
}
Tk::MainLoop;

All I want to know is, if at a later point of time using this same $hlist object how can I enter a new set of data in the 0th and 1st entrypath instead of the existing Joe->$10,000 and Peter->$20,000

Thanks
