求索阁

1》重载  virtual BOOL PreTranslateMessage(MSG* pMsg);

2》实现方法

<span style="font-size:16px;">BOOL Cpage1_listBox::PreTranslateMessage(MSG* pMsg)
{
    // TODO: 在此添加专用代码和/或调用基类
    if(WM_RBUTTONUP ==pMsg->message)
    {
        CPoint pt ;
        CRect rtClient;
        m_listBox.GetClientRect(&rtClient);
        m_listBox.ClientToScreen(&rtClient);
        INT iScrollPos= m_listBox.GetScrollPos(SB_VERT);
        GetCursorPos(&pt);
        int iSelect = (pt.y -rtClient.top+iScrollPos*m_listBox.GetItemHeight(0))/m_listBox.GetItemHeight(0);
        //CString st=_T("");
        //st.Format(_T("%d"),iSelect);
        //::AfxMessageBox(st);
        m_listBox.SetCurSel(iSelect);
        m_listBox.RedrawWindow();
        if(rtClient.PtInRect(pt)&&iSelect<m_listBox.GetCount())
        {
            CMenu MyMenu;
            MyMenu.LoadMenu(IDR_SYSTEMFILE_POPMENU);
            MyMenu.GetSubMenu(0)->TrackPopupMenu(TPM_RIGHTBUTTON,pt.x,pt.y,this,NULL);
            MyMenu.Detach();//Detaches a Windows menu from a CMenu object and returns the handle
        }
    }
    return CDialog::PreTranslateMessage(pMsg);
}</span>
