MFC CListCtrl类checkbox问题

Question

MFC项目用到CListCtrl控件，CListCtrl控件的view设置为list，而且style含有LVS_EX_CHECKBOXES，即每一行最前面都有一个checkbox，那么问题来了，我在勾选和取消checkbox时，怎么捕获checkbox的change消息

Answer 1

void CStatusBarDlg::OnClickStateList(NMHDR* pNMHDR, LRESULT* pResult) 
{
    DWORD dwPos = GetMessagePos();  
    CPoint point( LOWORD(dwPos), HIWORD(dwPos) );  

    m_StatusList.ScreenToClient(&point);  

    LVHITTESTINFO lvinfo;  
    lvinfo.pt = point;  
    lvinfo.flags = LVHT_ABOVE;  

    UINT nFlag;  
    int nItem = m_StatusList.HitTest(point, &nFlag);  
    //判断是否点在checkbox上  
    if(nFlag == LVHT_ONITEMSTATEICON)  
    {
        TRACE("You click CheckBox,Item will be Clicked!");
        }
    *pResult = 0;
}
