请看看这个问题
写了一个继承CStatic的CmStatic类,在对话框调用CmStatic为什么没有响应?

<<<<<<<<<CmStatic.h>>>>>>>>
#pragma once
class CmStatic :public CStatic
{
public:
DECLARE_MESSAGE_MAP()
afx_msg void OnLButtonDblClk(UINT nFlags, CPoint point);
};

<<<<<<<<CmStatic.Cpp>>>>>>
#include "stdafx.h"
#include "CmStatic.h"
BEGIN_MESSAGE_MAP(CmStatic, CStatic)
ON_WM_LBUTTONDBLCLK()
END_MESSAGE_MAP()

void CmStatic::OnLButtonDblClk(UINT nFlags, CPoint point)
{
AfxMessageBox(_T("rrr"));
CStatic::OnLButtonDblClk(nFlags, point);
}

******对话框中调用CmStatic********
<<<<<Dlg.h>>>>>>
CmStatic Str;

为什么Str双击鼠标没有响应呢?
请大家别笑,是不是很菜的问题

谢谢:)
