初始化双击MFC中的编辑控件

Question

I am trying to set an mouse click event on editbox and when I am double clicking on edit box it should bring up a message box.

ON_WM_LBUTTONDBLCLK(IDC_EDITItem, &MessageManage::OnItemDoubleClick)

void MessageManage::OnItemDoubleClick()
{
    MessageBox( m_strItemMsg, "Sample code", MB_OK | MB_ICONINFORMATION );
}

Answer 1

It's not taking double click event from edit box

One way to accomplish this is to derive your own class from CEdit and handle ON_WM_LBUTTONDBLCLK() . The following code responded to the double click on an edit control in a sample program.

BEGIN_MESSAGE_MAP(MyEdit, CEdit)
    ON_WM_LBUTTONDBLCLK()
END_MESSAGE_MAP()

// MyEdit message handlers

void MyEdit::OnLButtonDblClk(UINT nFlags, CPoint point)
{
    // TODO: Add your message handler code here and/or call default

    CEdit::OnLButtonDblClk(nFlags, point);
}

Answer 2

At alternative is to just use PreTranslateMessage on your dialog:

BOOL CMFCApplication1Dlg::PreTranslateMessage(MSG* pMsg)
{
    if (pMsg->message == WM_LBUTTONDBLCLK &&
        pMsg->hwnd == ::GetDlgItem(m_hWnd, IDC_EDIT1))
    {
        AfxMessageBox(_T("Run Code"));
        return TRUE; //Important!!! Message is handled
    }

    return CDialogEx::PreTranslateMessage(pMsg);
}
