Question

From the book I’m reading:

By default, QListWidget is read-only. If we wanted the user to edit
the items, we could set the view’s edit triggers using
QAbstractItemView::setEditTriggers(); for example, a setting of
QAbstractItemView::AnyKeyPressed means that the user can begin editing
an item just by starting to type.

So, I call the function in my code:

ui->listWidget->setEditTriggers(QAbstractItemView::AnyKeyPressed);

But when I select an item and start typing, nothing happens.

Answer 1

It turns out that the items themselves also have an editable flag, so after adding them I had to iterate all of them and set it. Now it’s working.

// set the editable flag for each item
for (int ii = 0; ii < ui->listWidget->count(); ii++) {
    ui->listWidget->item(ii)->setFlags(ui->listWidget->item(ii)->flags() | Qt::ItemIsEditable);
}
// set the editable triggers for the list widget
ui->listWidget->setEditTriggers(QAbstractItemView::AnyKeyPressed);
