## wxDocParentFrame

The wxDocParentFrame class provides a default top-level frame for applications using the document/view framework. This class can only be used for SDI (not MDI) parent frames.

It cooperates with the wxView, wxDocument, wxDocManager and wxDocTemplates classes.

See the example application in `samples/docview`.

### wxDocParentFrame::wxDocParentFrame

wxDocParentFrame(wxDocManager* manager, wxFrame *parent, wxWindowID id, const wxString& title, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxDEFAULT_FRAME_STYLE, const wxString& name = "frame")

Constructor.

### wxDocParentFrame::~wxDocParentFrame

~wxDocParentFrame()

Destructor.

### wxDocParentFrame::OnCloseWindow

void OnCloseWindow(wxCloseEvent& event)

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

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

    void wxDocParentFrame::OnCloseWindow(wxCloseEvent& event)
    {
      if (m_docManager->Clear(!event.CanVeto()))
      {
        this->Destroy();
      }
      else
        event.Veto();
    }
