Create multiple views in CChildFrame using CSplitterWnd

Question

I work with MFC MDI. I need to create views as follows. My ChildWnd is divided into two parts. This is LeftView, which is a CView, and RightView, which is a CScrollView. LeftView is divided into two parts: TreeView and FormView. How can i do this?

I finally solved this problem. I have written a solution for everyone who has a similar problem.

• In the CChildFrame class, declare CSplitterWnd m_SplitterWnd;

• In CChildFrame :: OnCreateClient, enter the following code:

  if(!m_SplitterWnd.CreateStatic(this, 1, 2))
  {
      TRACE("Failed to create splitter window");
      return FALSE;
  }
  pContext->m_pNewViewClass = RUNTIME_CLASS(CLeftView);
  m_SplitterWnd.CreateView(0, 0, pContext->m_pNewViewClass, CSize(0, 0), pContext);
  m_pLeftView=(CLeftView*)m_SplitterWnd.GetPane(0,0);
  CCreateContext context;
  context.m_pNewViewClass = pContext->m_pNewViewClass; //save original
  
  pContext->m_pNewViewClass = RUNTIME_CLASS(CRightView);
  m_SplitterWnd.CreateView(0, 1, pContext->m_pNewViewClass, CSize(0, 0), pContext);
  pContext->m_pNewViewClass = context.m_pNewViewClass; //return to original
  m_pRightView=(CRightView*)m_SplitterWnd.GetPane(0,1);
  
  int nWidth=rc.Width();
  m_SplitterWnd.SetColumnInfo(0, nWidth*0.25, 50);
  m_SplitterWnd.SetColumnInfo(1, nWidth*0.75, 50);
  

  CLeftView is a derived class of the MFC CView.

• CLeftView declares a member variable CSplitterWnd m_SplitterWnd;

• In CLeftView :: OnCreate add the following code:

  CCreateContext *pContext = (CCreateContext*) lpCreateStruct->lpCreateParams;
  
  if(!m_SplitterWnd.CreateStatic(this, 2, 1, WS_CHILD | WS_VISIBLE, AFX_IDW_PANE_FIRST+8))
  {
      TRACE("Failed to create splitter window");
      return FALSE;
  }
  pContext->m_pNewViewClass = RUNTIME_CLASS(CPhongView);
  m_SplitterWnd.CreateView(0, 0, pContext->m_pNewViewClass, CSize(0, 0), pContext);
  m_pPhongView=(CPhongView*)m_SplitterWnd.GetPane(0, 0);
  CCreateContext context;
  context.m_pNewViewClass = pContext->m_pNewViewClass; //save original
  
  pContext->m_pNewViewClass = RUNTIME_CLASS(CPhongInfo);
  m_SplitterWnd.CreateView(1, 0, pContext->m_pNewViewClass, CSize(0, 0), pContext);
  pContext->m_pNewViewClass = context.m_pNewViewClass; //return to original
  m_pPhongInfo=(CPhongInfo*)m_SplitterWnd.GetPane(1, 0);
  

  CPhongInfo - CFormView, CPhong View - CTreeView.

• CLeftView:: OnSize

  m_SplitterWnd.MoveWindow(0, 0, cx, cy);
  int nRow2 = 227;
  int nRow1 = cy - 227;
  m_SplitterWnd.SetRowInfo(0, nRow1, 0);
  m_SplitterWnd.SetRowInfo(1, nRow2, 0);
  m_SplitterWnd.RecalcLayout();
