<br>主题：分割窗口的一个问题
<br>内容：我编一个分割窗口的程序，如下：<BR>--------------------<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;CView1<BR>-------|------------<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |<BR> CView2| CView3<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |<BR>-------|------------<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp; CView4<BR><BR>-------------------<BR>但中间的一行总是被挤的没有高度，第一行如所设高度，其余的被第3行CVIEW4占满。代码如下<BR><BR>BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs,<BR>&nbsp;&nbsp;&nbsp;&nbsp;CCreateContext* pContext)<BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;if(m_wndSplitter1.CreateStatic(this,3, 1)==NULL)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter1.CreateView(0,0,RUNTIME_CLASS(CView1),CSize(0,100), pContext);<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter1.CreateView(2,0,RUNTIME_CLASS(CView4),CSize(0,200), pContext);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(m_wndSplitter2.CreateStatic(&amp;m_wndSplitter1,1,2,WS_CHILD|WS_VISIBLE,m_wndSplitter1.IdFromRowCol(1,0))==NULL)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter2.CreateView(0,0,RUNTIME_CLASS(CView2),CSize(100,100), pContext);<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter2.CreateView(0,1,RUNTIME_CLASS(CView3),CSize(100,100), pContext);<BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;return TRUE;<BR><BR>若将CVIEW4放到第2行，将CVIEW2和CVIEW3的分割放到第3行，就没问题。不知是和缘故？请指教？应如何实现我想要的分割？<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR>}

<br>内容：呵呵，好长时间没发过言了，说说吧！<BR>朋友，<BR>BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs,<BR>&nbsp;&nbsp;&nbsp;&nbsp;CCreateContext* pContext)<BR>{<BR>　　CRect cr;//加上这句<BR>　　GetClientRect(&amp;cr);//加上这句<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;if(m_wndSplitter1.CreateStatic(this,3, 1)==NULL)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter1.CreateView(0,0,RUNTIME_CLASS(CView1),CSize(0,100), pContext);<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter1.CreateView(2,0,RUNTIME_CLASS(CView4),CSize(0,200), pContext);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(m_wndSplitter2.CreateStatic(&amp;m_wndSplitter1,1,2,WS_CHILD|WS_VISIBLE,m_wndSplitter1.IdFromRowCol(1,0))==NULL)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter2.CreateView(0,0,RUNTIME_CLASS(CView2),CSize(100,100), pContext);<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter2.CreateView(0,1,RUNTIME_CLASS(CView3),CSize(100,100), pContext);<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;m_wndSplitter1.SetRowInfo(1,cr.Height()/3,0);//加上这句话就OK了<BR>&nbsp;&nbsp;&nbsp;&nbsp;return TRUE;<BR><BR>}

<br>内容：谢谢，但我还想了解不加这句话为什么会出现问题呢？而如果我将左右分割放在第三行，就不加这句话也行呢？这个函数应该在什么情况下用呢？请指教
