Qt/C++: Getting the data at a certain cell in a QTableView

I'm trying to get the text at a certain cell in a QTableView. For example:

QString codestring = "*" + ui->tblInventory->indexAt(QPoint(0,2)).data().toString() + "*";

This should get the text at the cell in column 0 row 2 in my QTableView. The problem is, tha开发者_如何学JAVAt's not what it's doing!. Regardless of the arguments I pass into the QPoint() in the indexAt(), I get the text at cell 0,0. I have no idea why this is... any help? Thanks!

[edit]

I've also tried this:

QString codestring = "*" + ui->tblInventory->model()->data(ui->tblInventory->indexAt(QPoint(0,2))).toString() + "*";

[Edit 2] Trying to find out what's going on, I put in this line of code:

qDebug()<< ui->tblInventory->indexAt(QPoint(2,2)).row() << " and " <<  ui->tblInventory->indexAt(QPoint(2,2)).column();

It should get the QModelIndex at cell 2,2 and output its row and its column, which of course should be 2 and 2. However, I get 0 and 0! So it seems like this might be a problem with QTableView::indexAt(), whether its my usage or some sort of bug. Can anyone shed some light?

Resolved with:

ui->tblInventory->model()->data(ui->tblInventory->model()->index(0,2)).toString()

Not quite sure why the above doesn't work, but this does. Thanks for the help.

This one work too and it's shorter:

QModelIndex index = model->index(row, col, QModelIndex());

ui->tblInventory->model()->data(index).toString();

(model used top is the QAbstractModel that is bound to this tblInventory)

Check the data() function provided by the model that your QTableView uses, the effect that you describe is probably observed due to a bug in it.

Try this:

QModelIndex index = ui->tblInventory->indexAt(p); // p is a QPoint you get from some where, may be you catch right click
QString codestring = "*" + index->data().toString() + "*";
