\section{\class{wxDocParentFrame}}\label{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 \helpref{wxView}{wxview}, \helpref{wxDocument}{wxdocument},
\rtfsp\helpref{wxDocManager}{wxdocmanager} and \helpref{wxDocTemplates}{wxdoctemplate} classes.

See the example application in {\tt samples/docview}.

Constructor.

\membersection{wxDocParentFrame::\destruct{wxDocParentFrame}}

\func{}{\destruct{wxDocParentFrame}}{\void}

Destructor.

\membersection{wxDocParentFrame::OnCloseWindow}

\func{void}{OnCloseWindow}{\param{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.

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