  The framework is highly modular, allowing overriding and replacement of functionality

  These are the overall steps involved in creating an application based on the document/view framework:

   Construct a single wxDocManager instance at the beginning of your wxApp::OnInit, and then
  as many wxDocTemplate instances as necessary to define relationships between documents and

  If you wish to implement Undo/Redo, you need to derive your own class(es) from wxCommand
  and use wxCommandProcessor::Submit instead of directly executing code. The framework will
  take care of calling Undo and Do functions as appropriate, so long as the wxID_UNDO and
  wxID_REDO menu items are defined in the view menu.
  Here are a few examples of the tailoring you can do to go beyond the default framework
  behaviour:
- 
- 
+
+
   Override wxDocument::OnCreateCommandProcessor to define a different Do/Undo strategy,
  or a command history editor.
   Override wxView::OnCreatePrintout to create an instance of a derived #wxPrintout
  class, to provide multi-page document facilities.
   Override wxDocManager::SelectDocumentPath to provide a different file selector.
   Limit the maximum number of open documents and the maximum number of undo commands.
