Qt Frozen Column example error when adding new column

[amban]

Hi,
I am using the Qt Frozen Column implementation in my application. [Reference : http://doc.qt.nokia.com/4.7-snapshot/itemviews-frozencolumn.html]

When I add the following function to my code :
@
dbTable = new FreezeTableWidget(mymodel);
void Widget::addColumn()
{
QModelIndexList list = dbTable->selectionModel()->selectedIndexes();
if (list.count() == 1)
{
QStandardItem *currentItem = mymodel->itemFromIndex(list[0]);

    colCount += 1 ;
    mymodel->insertColumn(currentItem->column()+1);

    for (int row = 0 ; row < rowCount ; ++row)
    {
        QStandardItem *item = new QStandardItem(QString("0"));
        mymodel->setItem(row, currentItem->column()+1, item);
    }
}
else
{
    QMessageBox::warning(this, "Error", "Mulitple entries selected.");
}

}
@

I initialize the table with 3 rows and 3 columns. It works perfectly fine.
But when i add this new column now and click on it....the frozen column displays values in the newly added column.
Where am I going wrong ?

Please advise.
Thanks very much for you help.
