cpp 复制代码

	void SetToolTipsMsgMap();                           //鼠标悬停提示
	BOOL PreTranslateMessage(MSG* pMsg);				//处理键盘和鼠标消息

cpp 复制代码

BOOL Settings::OnInitDialog()
{
	CDialogEx::OnInitDialog();

	EnableToolTips(true);     //使能悬停提示
	m_Ttc.Create(this);       //此窗口悬停提示
	SetToolTipsMsgMap();      //鼠标悬停提示
}
//处理键盘和鼠标消息
BOOL Settings::PreTranslateMessage(MSG* pMsg)
{
	CString cstrMessageOut;
	m_Ttc.RelayEvent(pMsg);     //鼠标悬停提示 
	return CDialog::PreTranslateMessage(pMsg);
}
//鼠标悬停提示
void Settings::DoDataExchange(CDataExchange* pDX)
{
	CDialogEx::DoDataExchange(pDX);
	m_Ttc.AddTool(GetDlgItem(IDC_STATIC), L"--");
	m_Ttc.AddTool(GetDlgItem(IDC_Combobox_sortMode), L"--");
	m_Ttc.AddTool(GetDlgItem(IDC_AllBuffer1),	  L"悬停提示1");
	m_Ttc.AddTool(GetDlgItem(IDC_Static_Number1), L"悬停提示2");
	m_Ttc.AddTool(GetDlgItem(IDC_Static_Number2), L"悬停提示3");
}
