\section{\class{wxDocMDIChildFrame}}\label{wxdocmdichildframe}

The wxDocMDIChildFrame class provides a default frame for displaying documents
on separate windows. This class can only be used for MDI child frames.

The class is part of the document/view framework supported by wxWidgets,
and cooperates with the \helpref{wxView}{wxview}, \helpref{wxDocument}{wxdocument},
\rtfsp\helpref{wxDocManager}{wxdocmanager} and \helpref{wxDocTemplate}{wxdoctemplate} classes.

See the example application in {\tt samples/docview}.
