and \helpref{wxDocManager}{wxdocmanager} classes.

-\membersection{wxView::m\_viewDocument}
+\membersection{wxView::m\_viewDocument}\label{wxviewmviewdocument}
\member{wxDocument*}{m\_viewDocument}
The document associated with this view. There may be more than one view per
document, but there can never be more than one document for one view.
-\membersection{wxView::m\_viewFrame}
+\membersection{wxView::m\_viewFrame}\label{wxviewmviewframe}
\member{wxFrame*}{m\_viewFrame}
Frame associated with the view, if any.
-\membersection{wxView::m\_viewTypeName}
+\membersection{wxView::m\_viewTypeName}\label{wxviewmviewtypename}
\member{wxString}{m\_viewTypeName}
The view type name given to the wxDocTemplate constructor, copied to this
variable when the view is created. Not currently used by the framework.
-\membersection{wxView::wxView}
+\membersection{wxView::wxView}\label{wxviewctor}
\func{}{wxView}{\void}
Constructor. Define your own default constructor to initialize application-specific
data.
-\membersection{wxView::\destruct{wxView}}
+\membersection{wxView::\destruct{wxView}}\label{wxviewdtor}
\func{}{\destruct{wxView}}{\void}
Destructor. Removes itself from the document's list of views.
-\membersection{wxView::Activate}
+\membersection{wxView::Activate}\label{wxviewactivate}
\func{virtual void}{Activate}{\param{bool}{ activate}}
Call this from your view frame's OnActivate member to tell the framework which view is
currently active. If your windowing system doesn't call OnActivate, you may need to
-call this function from OnMenuCommand or any place where you know the view must
+call this function from any place where you know the view must
be active, and the framework will need to get the current view.
-The prepackaged view frame wxDocChildFrame calls wxView::Activate from its OnActivate member
-and from its OnMenuCommand member.
+The prepackaged view frame wxDocChildFrame calls wxView::Activate from its OnActivate member.
This function calls wxView::OnActivateView.
-\membersection{wxView::Close}
+\membersection{wxView::Close}\label{wxviewclose}
-\func{virtual bool}{Close}{\param{bool}{ deleteWindow = TRUE}}
+\func{virtual bool}{Close}{\param{bool}{ deleteWindow = true}}
-Closes the view by calling OnClose. If {\it deleteWindow} is TRUE, this function should
+Closes the view by calling OnClose. If {\it deleteWindow} is true, this function should
delete the window associated with the view.
-\membersection{wxView::GetDocument}
+\membersection{wxView::GetDocument}\label{wxviewgetdocument}
\constfunc{wxDocument*}{GetDocument}{\void}
Gets a pointer to the document associated with the view.
-\membersection{wxView::GetDocumentManager}
+\membersection{wxView::GetDocumentManager}\label{wxviewgetdocumentmanager}
-\constfunc{wxDocumentManager*}{GetDocumentManager}{\void}
+\constfunc{wxDocManager*}{GetDocumentManager}{\void}
Returns a pointer to the document manager instance associated with this view.
-\membersection{wxView::GetFrame}
+\membersection{wxView::GetFrame}\label{wxviewgetframe}
-\func{wxFrame *}{GetFrame}{\void}
+\func{wxWindow *}{GetFrame}{\void}
-Gets the frame associated with the view (if any).
+Gets the frame associated with the view (if any). Note that this ``frame'' is
+not a wxFrame at all in the generic MDI implementation which uses the notebook
+pages instead of the frames and this is why this method returns a wxWindow and
+not a wxFrame.
-\membersection{wxView::GetViewName}
+\membersection{wxView::GetViewName}\label{wxviewgetviewname}
\constfunc{wxString}{GetViewName}{\void}
Gets the name associated with the view (passed to the wxDocTemplate constructor).
Not currently used by the framework.
-\membersection{wxView::OnActivateView}
+\membersection{wxView::OnActivateView}\label{wxviewonactivateview}
\func{virtual void}{OnActivateView}{\param{bool }{activate}, \param{wxView *}{activeView}, \param{wxView *}{deactiveView}}
Called when a view is activated by means of wxView::Activate. The default implementation does
nothing.
-\membersection{wxView::OnChangeFilename}
+\membersection{wxView::OnChangeFilename}\label{wxviewonchangefilename}
\func{virtual void}{OnChangeFilename}{\void}
Called when the filename has changed. The default implementation constructs a
suitable title and sets the title of the view frame (if any).
-\membersection{wxView::OnClose}
+\membersection{wxView::OnClose}\label{wxviewonclose}
\func{virtual bool}{OnClose}{\param{bool}{ deleteWindow}}
Implements closing behaviour. The default implementation calls wxDocument::Close
to close the associated document. Does not delete the view. The application
may wish to do some cleaning up operations in this function, {\it if} a
-call to wxDocument::Close succeeded. For example, if your application's
+call to wxDocument::Close succeeded. For example, if your views
all share the same window, you need to disassociate the window from the view
-and perhaps clear the window. If {\it deleteWindow} is TRUE, delete the
+and perhaps clear the window. If {\it deleteWindow} is true, delete the
frame associated with the view.
-\membersection{wxView::OnCreate}
+\membersection{wxView::OnClosingDocument}\label{wxviewonclosingdocument}
+
+\func{virtual void}{OnClosingDoocument}{\void}
+
+Override this to clean up the view when the document is being
+closed.
+
+\membersection{wxView::OnCreate}\label{wxviewoncreate}
\func{virtual bool}{OnCreate}{\param{wxDocument* }{doc}, \param{long}{ flags}}
or a derived class. This wxDocChildFrame provides user interface
elements to view and/or edit the contents of the wxDocument.
-By default, simply returns TRUE. If the function returns FALSE, the
+By default, simply returns true. If the function returns false, the
view will be deleted.
-\membersection{wxView::OnCreatePrintout}
+\membersection{wxView::OnCreatePrintout}\label{wxviewoncreateprintout}
\func{virtual wxPrintout*}{OnCreatePrintout}{\void}
Override to return an instance of a class other than wxDocPrintout.
-\membersection{wxView::OnUpdate}
+\membersection{wxView::OnDraw}\label{onviewondraw}
+
+\func{virtual void}{OnDraw}{\param{wxDC* }{dc}}
+
+Override this function to render the view on the given device context.
+
+\membersection{wxView::OnUpdate}\label{onviewonupdate}
\func{virtual void}{OnUpdate}{\param{wxView* }{sender}, \param{wxObject* }{hint}}
when the document is opened). {\it hint} is as yet unused but may in future contain
application-specific information for making updating more efficient.
-\membersection{wxView::SetDocument}
+\membersection{wxView::SetDocument}\label{wxviewsetdocument}
\func{void}{SetDocument}{\param{wxDocument* }{doc}}
Associates the given document with the view. Normally called by the
framework.
-\membersection{wxView::SetFrame}
+\membersection{wxView::SetFrame}\label{wxviewsetframe}
-\func{void}{SetFrame}{\param{wxFrame* }{frame}}
+\func{void}{SetFrame}{\param{wxWindow* }{frame}}
Sets the frame associated with this view. The application should call this
if possible, to tell the view about the frame.
-\membersection{wxView::SetViewName}
+See \helpref{GetFrame}{wxviewgetframe} for the explanation about the mismatch
+between the ``Frame'' in the method name and the type of its parameter.
+
+\membersection{wxView::SetViewName}\label{wxviewsetviewname}
\func{void}{SetViewName}{\param{const wxString\& }{name}}
Sets the view type name. Should only be called by the framework.
