How can I select a child node in a QTreeView?

nzur

Hi, I have a QTreeView with nested nodes, I need to select a child node according to an index in a table.
Here's what I do:

        QModelIndex nIndex = view.model()->index(tableIndex, 0);
        view.selectionModel()->clearSelection();
        view.selectionModel()->select(nIndex, QItemSelectionModel::Select | QItemSelectionModel::Rows);
        view.scrollTo(nIndex);

for example: when tableIndex == 3 I expect to select the 3rd child node, but this selects the 3rd parent row

index(tableIndex, 0)

You are missing the 3rd argument of index. How can it know what parent to take it from? for example, for the third child of the first parent:
QModelIndex nIndex = view.model()->index(tableIndex, 0, view.model()->index(0,0));
