BUG?: CXTTreeCtrl beeps when pressing VK_RETURN

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Hi;
This can be seen in toolkit TreeCtrl sample too:

When pressing the ENTER key (VK_RETURN) while a parent node is selected, the expansion state changes, but also a system beep occures (not handled SYSKEYS; e.g. accelerators lead to system sounds)!

I think that CXTTreeBase::PreTranslateMessage() should be changed as shown below (Oleg, could you apply this?):

BOOL CXTTreeBase::PreTranslateMessage(MSG* pMsg)
{
    if (pMsg->message == WM_KEYDOWN)
    {
        // ensure that keystrokes are handled by the edit control.
        if (HasEditLabels() && m_pTreeCtrl->GetEditControl())
        {
            ::TranslateMessage(pMsg);
            ::DispatchMessage(pMsg);

            return TRUE;
        }

        // toggle expand / contract when return key is hit.
        if (pMsg->wParam == VK_RETURN)
        {
            HTREEITEM htItem = m_pTreeCtrl->GetSelectedItem();
            if (htItem != NULL)
            {
                m_pTreeCtrl->Expand(htItem, TVE_TOGGLE);
                return TRUE;
            }
        }
    }

    return m_pTreeCtrl->CTreeCtrl::PreTranslateMessage(pMsg);
}

I'm using toolkit version 12.0.1, VC++ 7.1...
