[QT4 & XP] retrieve data from QTreeView's model

hi,:o

in the following code table is a QTreeView based on a QStandardItemModel with 2 columns:

Code:

---

connect( table, SIGNAL( doubleClicked(const QModelIndex&) ), 
            this, SLOT( selection(const QModelIndex&) ) );

---

When the slot is activated, I would like to retrieve the selected data from the model like :

Code:

---

void MainWindow::selection(const QModelIndex& idx)
{
    QString col0 = model->data(QModelIndex(idx)).toString();
}

---

This returns the selected item allright (col0 or col1 depending on the user's selection).
But I need to retrieve data for both columns.
How is that achieved ?

You can "iterate" in your model by using QModelIndex methods parent(), child(), sibling()..
One way to fetch data in both colums:

Code:

---

QString col0 = model->data(idx.sibling(idx.row(), 0)).toString();
QString col1 = model->data(idx.sibling(idx.row(), 1)).toString();

---

Edit: Btw, you don't need to store a pointer to the model as a member variable for this kind of purpose.
You can reach the data by using only model indexes as well:

Code:

---

QString col0 = idx.sibling(idx.row(), 0).data().toString();
