Changing view in a static splitterView

I have  a 3 way splitter window with this configuration.

           | View 2
 View1  |---------
           | View 3

I create it with CreateStatic().

Thanks to an action on view1, I want to change view2 (from ClistView to CFormView, for example).
Unfortunatly 'from MSDN CSplitterWnd::CreateView ' :

'All panes of a static splitter window must be created before the framework displays the splitter.'

So how can I change it dynamicly?

Thanks for help in advance

Check out Q196832 in Microsoft knowledge base http://support.microsoft.com/support/kb/articles/Q196/8/32.ASP


This article demonstrates how to use a static splitter window in a traditional SDI document-view architecture. The article shows how to design an application that can switch between a single view and a splitter window that can embed as many panes as necessary.

You can easily expand the code to support static splitter windows with different numbers of panes, depending on some run-time conditions.

1) derive a splitter window class from CSplitterWnd and create a variable of that type in your main frame

2) create the new view:
CRuntimeClass* pView = RUNTIME_CLASS(YourNewViewClass);
int nView = nSomeViewID;
CView* pNewView = (CView*)pView->CreateObject();

if (pNewView)
{
    pNewView->Create(NULL, NULL, 0L, CFrameWnd::rectDefault, pParentWnd, nView, pContext);
      
pNewView->OnInitialUpdate();
} // end if


3) change to the new view:

UINT CYourSplitterWnd::ChangeView(CView* pNewPaneView, int row, int col, UINT nOldViewID, bool bFirstView)
{
     UINT nPaneViewID = IdFromRowCol(row, col);
     UINT nNewViewID  = pNewPaneView->GetDlgCtrlID();

     if (nNewViewID == 0)
     {
      return 0;
     } // end if
     else if (nNewViewID != (UINT) m_nCurrentViewID)
     {
      m_nCurrentViewID = nNewViewID;

      // set new view active and show it...
      CFrameWnd* pFrameWnd = GetParentFrame();

      pFrameWnd->SetActiveView(pNewPaneView);
      pNewPaneView->ShowWindow(SW_SHOW);
            
      // get old view, hide it, and remove from the splitter...
      CView* pOldPaneView = (CView*)GetDlgItem(nPaneViewID);

      if (pOldPaneView)
      {
            pOldPaneView->ShowWindow(SW_HIDE);
            pOldPaneView->SetDlgCtrlID(nOldViewID);
      } // end if

      // add the new view to the splitter...
      if (pNewPaneView->GetParent() != this)
            pNewPaneView->SetParent(this);

      pNewPaneView->SetDlgCtrlID(nPaneViewID);

      if (!bFirstView)
            RecalcLayout();
      } // end else
      
      return nNewViewID;
} // end ChangeView()


I belive that's the basics of it...
hope that helps...

Hi,

Have the pointers of the CSplitterWnd and create them and display them. When U want to change it, delete the pointers so that view goes off and display the fresh view with the required change freshly. That should work though it is a work around method.

I had the similar problem, on some action, the requirement was to delete the view2 and show view1 abd view3 only. There I have followed the same way. I still have the sample of it too.

Try it out.
