\section{\class{wxClientData}}\label{wxclientdata}
All classes deriving from \helpref{wxEvtHandler}{wxevthandler}
(such as all controls and \helpref{wxApp}{wxapp})
can hold arbitrary data which is here referred to as "client data".
This is useful e.g. for scripting languages which need to handle
shadow objects for most of wxWindows' classes and which store
a handle to such a shadow class as client data in that class.
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.
Some controls can hold various items and these controls can
additionally hold client data for each item. This is the case for
\helpref{wxChoice}{wxchoice}, \helpref{wxComboBox}{wxcombobox}
and \helpref{wxListBox}{wxlistbox}. \helpref{wxTreeCtrl}{wxtreectrl}
has a specialized class \helpref{wxTreeItemData}{wxtreeitemdata}
for each item in the tree.
If you want to add client data to your own classes, you may
use the mix-in class \helpref{wxClientDataContainer}{wxclientdatacontainer}.

\section{\class{wxClientDataContainer}}\label{wxclientdatacontainer}
This class is a mixin that provides storage and management of "client
data." 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 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.
NOTE: This functionality is currently duplicated in wxEvtHandler in
order to avoid having more than one vtable in that class heirachy.
