\section{\class{wxDocument}}\label{wxdocument}
The document class can be used to model an application's file-based
-data. It is part of the document/view framework supported by wxWindows,
+data. It is part of the document/view framework supported by wxWidgets,
and cooperates with the \helpref{wxView}{wxview}, \helpref{wxDocTemplate}{wxdoctemplate}\rtfsp
and \helpref{wxDocManager}{wxdocmanager} classes.

\func{virtual bool}{OnCreate}{\param{const wxString\& }{path}, \param{long}{ flags}}
