Getting / setting data on QTableWidgets

[Santosh Reddy]

QTableWidgetItem * QTableWidget::itemAt ( const QPoint & point ) const

QTableWidgetItem * QTableWidget::itemAt ( int ax, int ay ) const

for both the functions the parameter is point (in table widget's coordinate system), this is not row & column. This is the reason for empty in the text().

Try using this
QTableWidgetItem * QTableWidget::item ( int row, int column ) const

Use the second method.
First method should also work if Qt::UserRole is changed to Qt:: DataRole
