用CSplitterWnd动态分割窗口的时候，如何开始不需要拖动分割条，按左键显示分割条

[bjliuqi]

用VC6 wizard创建的分割窗口的工程， 点一下 窗口中的分隔，需要移动鼠标，按左键才能显示分割条，现在我的问题是我想开始就像静态分割那样，点击一下分隔 就能立即出现分隔条，例如可以让他显示在窗口的中央。 谢谢。

点击一下分隔 是什么意思 - -

CSplitterWnd没有此功能，除非你自己做一个出来

这个试试。
1)建立个CSplitterWnd的派生类CMySptWnd。
class CMySptWnd : public CSplitterWnd
并定一个成员变量bool m_bIs;，
初始化为false

2）分割成上下两个窗口。

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) 
{
      if(m_wndSplitter.CreateStatic(this,2,1)==NULL) //CMySptWnd m_wndSplitter;
        return FALSE;

      m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(CView11View),CSize(0,0), pContext); 
      m_wndSplitter.CreateView(1,0,RUNTIME_CLASS(CView11View),CSize(100,100),pContext); 	

3）定义函数：

void CMySptWnd::SetSpl(CPoint pt)
{
enum HitTestValue
{
	noHit                   = 0,
	vSplitterBox            = 1,
	hSplitterBox            = 2,
	bothSplitterBox         = 3,        // just for keyboard
	vSplitterBar1           = 101,
	vSplitterBar15          = 115,
	hSplitterBar1           = 201,
	hSplitterBar15          = 215,
	splitterIntersection1   = 301,
	splitterIntersection225 = 525
};
	if (m_bTracking)
	{
		// move tracker to current cursor position

		pt.Offset(m_ptTrackOffset); // pt is the upper right of hit detect
		// limit the point to the valid split range
		if (pt.y < m_rectLimit.top)
			pt.y = m_rectLimit.top;
		else if (pt.y > m_rectLimit.bottom)
			pt.y = m_rectLimit.bottom;
		if (pt.x < m_rectLimit.left)
			pt.x = m_rectLimit.left;
		else if (pt.x > m_rectLimit.right)
			pt.x = m_rectLimit.right;

		if (m_htTrack == vSplitterBox ||
			m_htTrack >= vSplitterBar1 && m_htTrack <= vSplitterBar15)
		{
			if (m_rectTracker.top != pt.y)
			{
				OnInvertTracker(m_rectTracker);
				m_rectTracker.OffsetRect(0, pt.y - m_rectTracker.top);
				OnInvertTracker(m_rectTracker);
			}
		}
		else if (m_htTrack == hSplitterBox ||
			m_htTrack >= hSplitterBar1 && m_htTrack <= hSplitterBar15)
		{
			if (m_rectTracker.left != pt.x)
			{
				OnInvertTracker(m_rectTracker);
				m_rectTracker.OffsetRect(pt.x - m_rectTracker.left, 0);
				OnInvertTracker(m_rectTracker);
			}
		}
		else if (m_htTrack == bothSplitterBox ||
		   (m_htTrack >= splitterIntersection1 &&
			m_htTrack <= splitterIntersection225))
		{
			if (m_rectTracker.top != pt.y)
			{
				OnInvertTracker(m_rectTracker);
				m_rectTracker.OffsetRect(0, pt.y - m_rectTracker.top);
				OnInvertTracker(m_rectTracker);
			}
			if (m_rectTracker2.left != pt.x)
			{
				OnInvertTracker(m_rectTracker2);
				m_rectTracker2.OffsetRect(pt.x - m_rectTracker2.left, 0);
				OnInvertTracker(m_rectTracker2);
			}
		}
	}
	else
	{
		// simply hit-test and set appropriate cursor

		int ht = HitTest(pt);
		SetSplitCursor(ht);
	}
}

4)重载OnLButtonUp函数

void CMySptWnd::OnLButtonUp(UINT nFlags, CPoint point) 
{
	CRect rc;
	GetWindowRect(&rc);
	if(point.x>rc.left && point.x<rc.right)//判断鼠标是否点在分割条上
	{

		if(m_bIs==false)
		{
			SetSpl(CPoint(0,(rc.bottom-rc.top)/2));
			m_bIs = !m_bIs;
		}
		else
		{
			SetSpl(CPoint(0,0));
			m_bIs = !m_bIs;
		}
	}
	
	CSplitterWnd::OnLButtonUp(nFlags, point);
}
