\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.

A convenience function to get the first view for a document, because
in many cases a document will only have a single view.

\constfunc{virtual bool}{IsModified}{\void}
-Returns TRUE if the document has been modified since the last save, FALSE otherwise.
+Returns true if the document has been modified since the last save, false otherwise.
You may need to override this if your document view maintains its own
record of being modified (for example if using wxTextWindow to view and edit the document).
\func{virtual istream\&}{LoadObject}{\param{istream\& }{stream}}
+\func{virtual wxInputStream\&}{LoadObject}{\param{wxInputStream\& }{stream}}
+
Override this function and call it from your own LoadObject before
streaming your own data. LoadObject is called by the framework
automatically when the document contents need to be loaded.
+Note that only one of these forms exists, depending on how wxWidgets
+was configured.

\membersection{wxDocument::OnCreate}
Called just after the document object is created to give it a chance
to initialize itself. The default implementation uses the
template associated with the document to create an initial view.

unmodified; otherwise, an error message box is displayed. The document's
views are notified that the filename has changed, to give windows an opportunity
to update their titles. All of the document's views are then updated.

-\func{void}{SetFilename}{\param{const wxString\& }{filename}}
+\func{void}{SetFilename}{\param{const wxString\& }{filename}, \param{bool}{ notifyViews = false}}
Sets the filename for this document. Usually called by the framework.

-\func{void}{UpdateAllViews}{\param{wxView* }{sender = NULL}}
+\func{void}{UpdateAllViews}{\param{wxView* }{sender = NULL}, \param{wxObject*}{ hint = NULL}}
Updates all views. If {\it sender} is non-NULL, does not update this view.
+{\it hint} represents optional information to allow a view to optimize its update.
