Get parent widget by object name

How do I get a parent object by its name? QWidget::parentWidget() goes only one level up; I rather need a recursive search equivalent to QObject::findChild().

QWidget inherits QObject so QObject::objectName is available to all QWidgets

You can recurse up the parent tree by creating a free function somewhat like the following (note this is untested code)

QWidget* parentByName(QWidget* widget, QString name)
{
    widget = parentWidget();
    if (widget && widget->objectName() != name)
        return parentByName(widget, name);
    return widget;
}

This will return either the widget you're looking for, or a nullptr in the event it can't be found
