I am trying to access a view inside a splitter from my mainframe. At the moment I have this:

CWnd* pView = m_wndSplitter.GetPane( 0, 0 );

However this gets me a pointer to the CWnd not the CMyViewClass object.

Can anyone explain to me what I need to do in order to access the view object itself so I can access member functions in the form pView->ViewFunction(…);

  1. Just cast it:

    // using MFC's dynamic cast macro CMyViewClass* pMyView =     DYNAMIC_DOWNCAST(CMyViewClass, m_wndSplitter.GetPane(0,0)); if ( NULL != pMyView )    // whatever you want to do with it...

    or:

    // standard C++  CMyViewClass* pMyView =     dynamic_cast<CMyViewClass*>(m_wndSplitter.GetPane(0,0)); if ( NULL != pMyView )    // whatever you want to do with it...

    If you know that the view in pane 0,0 will always be of type CMyViewClass, then you could just use static_cast… but i recommend you don’t – no sense risking problems should you ever change your layout.
