Detailed Description

Warning

This class causes invalid point exception when used with invalid QModelIndex instances. The index validation is not sufficient. This may cause unspecific crashes in situation where this class is used multiple times or with multiple selection models. See https://phabricator.mitk.org/T24348 for more information.
