Question

I have problem getting selected rows from QTableWidget. I have table like this:

[id]  [ key ]
 0     test
 1     pass

I want to get every row’s key values. I tried QTableWidget->selectedIndexes(); but it says it’s protected and I can’t access that. When I tried QTableWidget->SelectionModel->selectedIndexes, I don’t know how to loop through list and get the key values. Do anyone know better way how can I do it?
Regards.

I’m assuming that you set the selection behavior of your table widget to select rows.

You can always access the so-called “selection model” of any item view/widget. QTableWidget inherits from QAbstractItemView, which gives you access to this special model. This model can tell you the selected rows as a list of QModelIndex, which can then tell you the row. Once you’ve got them, you can access the table content, in your case the text in the column with index 1 (key column).

static const KEY_COLUMN = 1;

QList<QString> selectedKeys;
QItemSelectionModel *selectionModel = ui->tableWidget->selectionModel();
foreach(QModelIndex index, selectionModel->selectedRows())
    selectedIDs << ui->tableWidget->item(index->row(), KEY_COLUMN)->text();
