set column as not editable in Qtablewidget

connect(ui->widget,SIGNAL(cellDoubleClicked(int,int)),this,SL OT(column_check(int,int)));


void Saleorder::column_check(int row,int column)
{
QTableWidgetItem* itemtot=ui->widget->item(row, 9);

if( column == 9 )
{
if (itemtot && !itemtot->text().isEmpty())
{
itemtot->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled );
}

}
}
i tried this but the program is crashed.

Any one help me solve the problem.

Is there is any other way to achieve to make the entire column as not editable

Thanks in advance

Code:

---

tableWidgetItem->setFlags(tableWidgetItem->flags() & (~Qt::ItemIsEditable));

---

Remove your signal-slot code.

I used another way

Qt::ItemFlags Saleorder::flags( const QModelIndex &index) const
{
Qt::ItemFlags flags = QSqlTableModel::flags(index);
if (index.column() == 9 )
flags &= ~Qt::ItemIsEditable;
return flags;
}


But i need to know.how can i call this method

calling by the method name. I think you dont know the concept of c++.
