振动理论

1.使用MFC建立一个SDI(基类为View)，工程名为SplitWndDemo；

2.在 CMainFrame中增加变量

public:
   CSplitterWnd m_wndSplitter;

3.增加左右视图类，CLeftTreeView:public: CTreeView,如下：

#include <afxcview.h>
/////////////////////////////////////////////////////////////////////////////
// CLeftTreeView view
#include "TestDlg.h"
class CLeftTreeView : public CTreeView

#include "TestDlg.h"
/////////////////////////////////////////////////////////////////////////////
// CRightView view

CRightView : public CView如下：

class CRightView : public CView

4.重载CMainFrame的OnCreateClient（）函数

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
 // TODO: Add your specialized code here and/or call the base class
 // create splitter window
 if (!m_wndSplitter.CreateStatic(this, 1, 2))
  return FALSE;

 if (!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CLeftTreeView),CSize(200, 100), pContext) ||
  !m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CRightView), CSize(100, 100), pContext))
 {
  m_wndSplitter.DestroyWindow();
  return FALSE;
 }
 //set the target for mapped messages
// ((CFormLeft*)m_wndSplitter.GetPane(0,0))->SetTarget(m_wndSplitter.GetPane(0,1));

 return TRUE;
}

5.插入一个对话框，假如一个CEdit控件，控件名为IDC_EDIT1，类名为CTestDlg；

6.在CLeftTreeView中增加函数

HTREEITEM FindItem(long lItemData);

HTREEITEM CLeftTreeView::FindItem(long lItemData)
{
 // the tree object
 CTreeCtrl   &tTree = this->GetTreeCtrl ();
 // the current item
    HTREEITEM    tiItem= tTree.GetNextItem(TVGN_ROOT,TVGN_ROOT);
 long      lCurrentData;
 
    while (tiItem)
 {
  tTree.Expand(tiItem,TVE_EXPAND);
  
  lCurrentData = (long)tTree.GetItemData(tiItem);
  
  if( lCurrentData == lItemData )
   return tiItem;
  tiItem= tTree.GetNextItem(tiItem,TVGN_NEXTVISIBLE);
 }
 
 return NULL;
 
}

7.在CLeftTreeView::OnInitialUpdate() 函数中添加代码：

void CLeftTreeView::OnInitialUpdate()
{
 CTreeCtrl   &tTree = this->GetTreeCtrl ();
 
 // variables to compute new items
 long  lItemTitle;
 CString  sItemTitle;
 char  cItemTitle[10];
 int   iItemSize;
 int   iCptr;
 
 // item created
 HTREEITEM tiTestNode;
 HTREEITEM tiParentNode;
 
 CTreeView::OnInitialUpdate();
 
 // update the tree style
    tTree.ModifyStyle ( 0, TVS_HASLINES | TVS_HASBUTTONS | TVS_LINESATROOT);
 
   
 // Add items to the tree
 for(lItemTitle=1; lItemTitle<=999; lItemTitle+=2)
 {
  ltoa(lItemTitle,cItemTitle,10);
  sItemTitle = "";
  iItemSize= strlen(cItemTitle);
  
  sItemTitle=sItemTitle+cItemTitle[0];
  
  for(iCptr=1; iCptr<iItemSize; iCptr++)
  {
   sItemTitle=sItemTitle+"."+cItemTitle[iCptr];
  }
  // insert the node
  tiParentNode = FindItem((long)(lItemTitle/10));
  //for the first level nodes
  if((long)(lItemTitle/10)==0)
  {
   tiTestNode = tTree.InsertItem(sItemTitle);
   tTree.SetItemData(tiTestNode,lItemTitle);
  }
  //for the other nodes
  if( tiParentNode )
  {
   tiTestNode = tTree.InsertItem(sItemTitle, tiParentNode);
   tTree.SetItemData(tiTestNode,lItemTitle);
  }
 }
}

8.增加消息响应函数：使用ClassWizard增加消息响应函数CLeftTreeView::OnSelchanged()

void CLeftTreeView::OnSelchanged(NMHDR* pNMHDR, LRESULT* pResult)
{
 NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
 // TODO: Add your control notification handler code here
 TVITEM item = pNMTreeView->itemNew;
 CString strCurSelItemText = this->GetTreeCtrl().GetItemText(item.hItem); 
 CMainFrame * pMainFrm = (CMainFrame*)AfxGetMainWnd();
 CRightView * pRightView = (CRightView *)pMainFrm->m_wndSplitter.GetPane(0,1);
 if(pRightView->m_TestDlg.GetSafeHwnd())
 {
  pRightView->m_TestDlg.SetDlgItemText(IDC_EDIT1,strCurSelItemText);
 }
 *pResult = 0;
}

9.在CRightView增加变量CTestDlg m_TestDlg;

在 CRightView::OnInitialUpdate() 中添加代码：

void CRightView::OnInitialUpdate()
{
 CView::OnInitialUpdate();
 // TODO: Add your specialized code here and/or call the base class 
 if(!m_TestDlg.GetSafeHwnd()) //第一次初始化m_Tab 控件和page页的建立
 {
  m_TestDlg.Create(IDD_TestDlg,this);
  m_TestDlg.ShowWindow(SW_SHOW);
 } 
 
}
10.在vCRightView::OnSize()中添加代码：

oid CRightView::OnSize(UINT nType, int cx, int cy)
{
 CView::OnSize(nType, cx, cy);
 // 让窗体覆盖在上面。 
 if(m_TestDlg.GetSafeHwnd())
 {
  CRect rect;
  GetClientRect(rect);
  m_TestDlg.MoveWindow(rect);
  m_TestDlg.ShowWindow(SW_SHOW);
 }
 // TODO: Add your message handler code here
}

11.编译运行！
