how to select QTableWidget index in QT?

amarism

I want to select index of tablewidget. Where i can take 4 row, 5 column. So, I need to write the SIGNAL/SLOT for selecting index of the particular cell?

VRonin

tableWidget->selectionModel()->select(tableWidget->model()->index(4,5),QItemSelectionModel::ClearAndSelect);

@VRonin

constructure:: ...()
{
connect(this->twidget, SIGNAL(clicked(const QModelIndex &)), this, SLOT(onTableCellClicked(const QModelIndex &)));
};

void window::onTableCellClicked(const QModelIndex &index)
{
qDebug() << index;
}

But onClick iit will not forwarded to the SLOT section

Hi
Are you sure you have NEW'ed the instance ?
constructure:: ...()
{
connect(this->twidget <<< did you NEW this ?

also check the return of connect to see if it says TRUE
