   2
   3 The wxDocParentFrame class provides a default top-level frame for
   4 applications using the document/view framework. This class can only be used for SDI (not 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}.

  43 Deletes all views and documents. If no user input cancelled the
  44 operation, the frame will be destroyed and the application will exit.

  46 Since understanding how document/view clean-up takes place can be difficult,
  47 the implementation of this function is shown below.

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