Make all items in a QTreeWidget editable

Question

Is it possible to make all items in a QTreeWidget editable on user double-click?

I have already set the only editing-related property I found - editTriggers - to DoubleClicked|EditKeyPressed , but the items are still not editable.

I found the answer from https://forum.qt.io/topic/20980/solved-can-qtreewidget-really-be-edited . Apparently each item needs to have its editable flag set.

To do it, I iterated over all of the items and set the editable flag:

QTreeWidgetItemIterator it(ui->treeWidget);
while (*it) {
    (*it)->setFlags((*it)->flags() | Qt::ItemIsEditable);
    ++it;
}

It works after that!
