Description:
 def closeEditor(self, editor, hint):
 """ Finalizes, closes and releases the given editor. """

        # It would be nicer if this method was part of ConfigItemDelegate since createEditor also
        # lives there. However, QAbstractItemView.closeEditor is sometimes called directly,
        # without the QAbstractItemDelegate.closeEditor signal begin emitted, e.g when the
        # currentItem changes. Therefore we cannot connect the QAbstractItemDelegate.closeEditor
        # signal to a slot in the ConfigItemDelegate.
        configItemDelegate = self.itemDelegate()
        configItemDelegate.finalizeEditor(editor)

        super(ConfigTreeView, self).closeEditor(editor, hint)
