mfc - 使用 CSplitterWnd 在 CChildFrame 中创建多 View

我正在使用 MFC MDI。我需要创建如下 View 。我的 ChildWnd 分为两部分。它们是 LeftView，它是一个 CView 和 RightView，它是一个 CScrollView。 LeftView 分为两部分，TreeView 和 FormView。我该怎么做？

Answer 1

我终于解决了这个问题。我为遇到类似问题的任何人编写了解决方案。

1. 在CChildFrame类中，声明CSplitterWnd m_SplitterWnd;

2. 在 CChildFrame::OnCreateClient 中放置以下代码:

   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 是 MFC CView 的派生类。

3. 在CLeftView中声明一个成员变量CSplitterWnd m_SplitterWnd;

4. 在 CLeftView::OnCreate 中，添加以下代码:

   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是CFormView的派生类，CPhongView是CTreeView的类。

5. 在 CLeftView::OnSize 中，放入以下代码

   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();
