   2
   3 The wxDocMDIParentFrame class provides a default top-level frame for
   4 applications using the document/view framework. This class can only be used for MDI parent frames.
   5
   6 It cooperates with the \helpref{wxView}{wxview}, \helpref{wxDocument}{wxdocument},
   7 \rtfsp\helpref{wxDocManager}{wxdocmanager} and \helpref{wxDocTemplates}{wxdoctemplate} classes.
   8
   9 See the example application in {\tt samples/docview}.

  44 Deletes all views and documents. If no user input cancelled the
  45 operation, the frame will be destroyed and the application will exit.
  46
  47 Since understanding how document/view clean-up takes place can be difficult,
  48 the implementation of this function is shown below.

  51 void wxDocParentFrame::OnCloseWindow(wxCloseEvent& event)
  52 {
  53   if (m_docManager->Clear(!event.CanVeto()))
  54   {
  55     this->Destroy();
  56   }
  57   else
  58     event.Veto();
