使用CSplitterWnd实现拆分窗口（多视图显示）

void CXXSplitterWnd::OnLButtonDown(UINT nFlags,CPoint point) 
{
    CWnd::OnLButtonDown(nFlags,point);
}

void CSplitterWndEx::OnDrawSplitter(CDC *pDC, ESplitType nType, const CRect &rectArg){ 
	if(pDC==NULL)
	{
		RedrawWindow(rectArg,NULL,RDW_INVALIDATE|RDW_NOCHILDREN);
		return;
	} 
	ASSERT_VALID(pDC); 
	CRect rc=rectArg; 
	switch(nType)
	{ 
	case splitBorder: 
		//重画分割窗口边界,使之为红色 
		pDC->Draw3dRect(rc,RGB(255,0,0),RGB(255,0,0));  
		rc.InflateRect(-CX_BORDER,-CY_BORDER); 
		pDC->Draw3dRect(rc,RGB(255,0,0),RGB(255,0,0)); 
		return;
	case splitBox:  
		pDC->Draw3dRect(rc,RGB(0,0,0),RGB(0,0,0));
		rc.InflateRect(-CX_BORDER,-CY_BORDER); 
		pDC->Draw3dRect(rc,RGB(0,0,0),RGB(0,0,0)); 
		rc.InflateRect(-CX_BORDER,-CY_BORDER);
		pDC->FillSolidRect(rc,RGB(0,0,0)); 
		pDC->Draw3dRect(rc,RGB(0,0,0),RGB(0,0,0));
		return; 
	case splitBar:  
		//重画分割条，使之为绿色  
		pDC->FillSolidRect(rc,RGB(255,255,255));
		rc.InflateRect(-5,-5); 
		pDC->Draw3dRect(rc,RGB(255,0,0),RGB(255,0,0)); 
		return;  
	default:
		ASSERT(FALSE);
	} 
	pDC->FillSolidRect(rc,RGB(0,0,255));
}

void CSplitterWndEx::OnInvertTracker(CRect &rect) 
{
	ASSERT_VALID(this); 
	ASSERT(!rect.IsRectEmpty()); 
	ASSERT((GetStyle()&WS_CLIPCHILDREN)==0);
	CRect rc=rect;  
	rc.InflateRect(2,2);
	CDC* pDC=GetDC(); 
	CBrush* pBrush=CDC::GetHalftoneBrush(); 
	HBRUSH hOldBrush=NULL; 
	if(pBrush!=NULL) hOldBrush=(HBRUSH)SelectObject(pDC->m_hDC,pBrush->m_hObject);
	pDC->PatBlt(rc.left,rc.top,rc.Width(),rc.Height(),BLACKNESS);

		SelectObject(pDC->m_hDC,hOldBrush);
	ReleaseDC(pDC);
}

用MFC将SDI窗口三叉拆分并初始化各个View

最近做MFC界面，发现《深入浅出MFC》等很多资料里只是教我们如何将窗口三叉拆分，但是拆分后每个View类的初始化和设置很少有资料设计，让我这种初学者郁闷乐半天。这里是我自己的总结，十分简陋……

我需要三个试图，一个ListView，一个TreeView和一个EditView。类似于vc6的界面最下方为list，上部分左边为tree，右边为edit。首先，创建一个工程PaperInfoCrawler，选择SDI窗口，并将CPaperInfoCrawer继承CListview

在MainFram中加入变量 CSplitterWnd m_wndSplitter和CSplitterWnd m_wndTopSplitter并重载函数virtual BOOL OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)，下面为函数内容

{
  m_wndSplitter.CreateStatic(this,2,1);
  m_wndSplitter.SetRowInfo(0,450,450);
  m_wndTopSplitter.CreateStatic(&m_wndSplitter,1,2,WS_CHILD|WS_VISIBLE,m_wndSplitter.IdFromRowCol(0,0));
  m_wndTopSplitter.CreateView(0,0,RUNTIME_CLASS(CMyTreeView),CSize(300,0),pContext);
  m_wndTopSplitter.CreateView(0,1,RUNTIME_CLASS(CMyEditView),CSize(0,0),pContext);
  m_wndSplitter.CreateView(1,0,RUNTIME_CLASS(CPaperInfoCrawerView),CSize(0,0),pContext);
  return TRUE;
}

这其中CMyTreeView和CMyEditView是自己继承的View类，CPaperInfoCrawerView为自动生成的类，此时需要在MainFram.cpp中include相应的头文件。这时候编译通过应该窗口已经被划分为三部分了，下面开始对各个View进行初始化。

MyTreeView.cpp中增加变量 CTreeCtrl* ptheTree重载virtual void OnInitialUpdate()函数内容为

{
  CTreeView::OnInitialUpdate();
  ptheTree=&GetTreeCtrl();
  ptheTree->ModifyStyle(0,TVS_HASLINES|TVS_LINESATROOT|TVS_HASBUTTONS|TVS_EDITLABELS);
  TVINSERTSTRUCT tvInsert;
  HTREEITEM hTreeItem;
  tvInsert.hInsertAfter = NULL;//TVI_LAST;
  tvInsert.hParent = TVI_ROOT;
  tvInsert.item.mask = TVIF_TEXT;
  tvInsert.item.pszText = "搜索引擎";
  hTreeItem = ptheTree->InsertItem(&tvInsert);
  tvInsert.hParent = hTreeItem;
  tvInsert.item.pszText = "Google";
  ptheTree->InsertItem(&tvInsert);
  tvInsert.item.pszText = "Baidu";
  ptheTree->InsertItem(&tvInsert);
  ptheTree->Expand(hTreeItem,TVE_EXPAND); //默认为合上的TVE_COLLAPSE,打开的TVE_EXPAND
}

PaperInfoCrawler.cpp中增加变量 CListCtrl* ptheList重载virtual void OnInitialUpdate()函数内容为

{
  CListView::OnInitialUpdate();

  ptheList=&GetListCtrl();
  ptheList->ModifyStyle(0,LVS_REPORT | LVS_SHOWSELALWAYS | LVS_SORTASCENDING);
  ptheList->SendMessage(LVM_SETEXTENDEDLISTVIEWSTYLE,0,LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT);
  ptheList->InsertColumn(0,"标题",LVCFMT_LEFT,200,0);
  ptheList->InsertColumn(1,"URL",LVCFMT_LEFT,200,0);
  ptheList->InsertColumn(2,"引擎",LVCFMT_LEFT,200,0);
  int pos;
  pos = ptheList->InsertItem(0,"123");
  ptheList->SetItemText(pos,1,"http:\\\\");
  ptheList->SetItemText(pos,2,"Google");
}

编译通过就可以发现每个窗口都按我们的要求进行了划分和初始化

//获取主窗口
CMainFrame* pFrame=static_cast<CMainFrame*>(AfxGetMainWnd());

//获取某个view
CMyTreeView* pView=static_cast<CMyTreeView*>(pFrame->m_wndTopSplitter.GetPane(0,0));

//激活View
pFrame->SetActiveView(pView);
pFrame->m_wndTopSplitter.RecalcLayout();

//想干什么就干什么
pView->XXXXXX();
pView->SendMessage(WM_PAINT);

通过以上代码我们就可以在各个view间互相通信了。
