策略为王源代码扩展系列-分时图（3）-为分时图增加鼠标十字光标

step 1.未RealTimeView：添加鼠标移动事件消息处理 

添加

 src/Client/StkUI/View/RealTimeView.h

	afx_msg BOOL OnEraseBkgnd(CDC* pDC);
	afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
	afx_msg void OnLButtonUp(UINT nFlags, CPoint point);
	afx_msg void OnLButtonDblClk(UINT nFlags, CPoint point);
	afx_msg void OnLButtonDblClk(UINT nFlags, CPoint point);	
	/****extend 鼠标移动 by freeman****/
	afx_msg void OnMouseMove(UINT nFlags, CPoint point);
	/**************************************/
	afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);
	afx_msg void OnRealtimePrev();
	afx_msg void OnRealtimeNext();

添加ON_WM_MOUSEMOVE()消息和对应的处理函数OnMouseMove()

 src/Client/StkUI/View/RealTimeView.cpp
BEGIN_MESSAGE_MAP(CRealTimeView, CView)
	//{{AFX_MSG_MAP(CRealTimeView)

//处理键盘事件
void CRealTimeView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) 
{

step 2:在RealTime：添加鼠标移动事件处理函数，供RealTimeView调用 

定义函数

 src/Client/StkUI/View/RealTime.h

	void		Move( int nMove, BOOL bShiftPressed, BOOL bCtrlPressed );
	void		OnLButtonDown( UINT nFlags, CPoint point, BOOL bShiftPressed, BOOL bCtrlPressed );

	CPoint		m_ptLastMovingLine;	// 记录鼠标移动线位置

	if (CRealTime::modePriceLine == m_nDrawMode)
	{
		// Selection
		int	nIndexClick = -1;
		CRect	rect(m_rectPrice.left, m_rectPrice.top, m_rectPrice.right, m_rectAll.bottom - m_nMarginBottom);
		if (rect.PtInRect(point))
		{
			DWORD	dwSeconds = CSPTime::GetTradeSecondsOfOneDay();
			for (int nIndex = 0; nIndex < m_CurStock.GetMinute().GetSize(); nIndex++)
			{
				CRect	rectLine = rect;
				DWORD sec = CSPTime(m_CurStock.GetMinute()[nIndex].m_time).ToStockTimeSecOrder();
				DWORD secL = sec - 100, secR = sec + 100;
				if (nIndex > 0)
					secL = CSPTime(m_CurStock.GetMinute()[nIndex - 1].m_time).ToStockTimeSecOrder();
				if (nIndex < m_CurStock.GetMinute().GetSize() - 1)
					secR = CSPTime(m_CurStock.GetMinute()[nIndex + 1].m_time).ToStockTimeSecOrder();
				rectLine.left = (int)(rect.left + rect.Width() * (secL + sec) * 0.5 / dwSeconds);
				rectLine.right = (int)(rect.left + rect.Width() * (sec + secR) * 0.5 / dwSeconds);
				if (rectLine.PtInRect(point))
				{
					nIndexClick = nIndex;
					break;
				}
			}
		}
		MoveTo(nIndexClick, false, false);
	}
}

step 3：当鼠标在RealTimeView移动时，调用 RealTime类中的CRealTime::OnMouseMove(UINT nFlags, CPoint point)  函数显示光标

 src/Client/StkUI/View/RealTimeView.cpp

/**** extend 鼠标移动 by freeman ****/
void CRealTimeView::OnMouseMove(UINT nFlags, CPoint point)
{
	//m_graph.OnMouseMove(nFlags, point);
	m_realtime[0].OnMouseMove(nFlags, point);
	CView::OnMouseMove(nFlags, point);
}
