策略为王源代码分析-浮动提示窗口（TitleTip.cpp）

G:\stock\TskingVS2019\src\Client\StkUI\TitleTip.h

定义了鼠标拖动窗口

class  CTitleTip : public CWnd
{
// Construction
public:
	CTitleTip();
	virtual ~CTitleTip();
	virtual BOOL Create( CWnd *pParentWnd);

// Attributes
public:

// Operations
public:
	void Show(CRect rectTitle, LPCTSTR lpszTitleText, 
              int xoffset = 0, LPRECT lpHoverRect = NULL, LPLOGFONT lpLogFont = NULL);
    void Hide();

// Overrides
	// ClassWizard generated virtual function overrides
	//{{AFX_VIRTUAL(CTitleTip)
	public:
	virtual BOOL PreTranslateMessage(MSG* pMsg);
	//}}AFX_VIRTUAL

// Implementation
public:

protected:
	CWnd *m_pParentWnd;
	CRect m_rectTitle;
    CRect m_rectHover;

	// Generated message map functions
protected:
	//{{AFX_MSG(CTitleTip)
	afx_msg void OnMouseMove(UINT nFlags, CPoint point);
	//}}AFX_MSG
	DECLARE_MESSAGE_MAP()
};

使用

经过查找，整个方案中只有GridCtrl用到。

G:\stock\TskingVS2019\src\Client\StkUI\GridCtrl.h

#ifndef GRIDCONTROL_NO_TITLETIPS
    CTitleTip   m_TitleTip;             // Title tips for cells  浮动提示窗 by freeman
#endif
