This data can either be of type void - in which case the data
{\it container} does not take care of freeing the data again
-or it is of type wxClientData or its derivates. In that case the

container (e.g. a control) will free the memory itself later.
Note that you {\it must not} assign both void data and data
derived from the wxClientData class to a container.
