Hello,

Now i changed from 9.60 to 9.81.
But now OnContextMenu with CXTTreeCtrl doesn't work.

class CMyTreeCtrl: public CXTTreeCtrl
{
    DECLARE_MESSAGE_MAP()
    afx_msg void OnContextMenu(CWnd* /*pWnd*/, CPoint /*point*/);
}

BEGIN_MESSAGE_MAP(CMyTreeCtrl, CXTTreeCtrl)
    ON_WM_CONTEXTMENU()
END_MESSAGE_MAP()

void CMyTreeCtrl::OnContextMenu(CWnd* /*pWnd*/, CPoint /*point*/)
{
    ...
show menu
...
}

Any solution ???

Why it is a ms problem ?
With CodeJock 9.60 it work correct.
But not with 9.81.
We use VS 2003

Hello,

i see. In 9.81 there are changes in
void CXTTreeBase::OnRButtonDown(UINT /*nFlags*/, CPoint point)
{
....
    // get the owner of the tree control.
    //HWND hWnd = m_pTreeCtrl->GetOwner()->m_hWnd;

    //if (::IsWindow(hWnd))
    //{
        // construct a NMHDR struct...
        //NMHDR mHDR;
        //mHDR.hwndFrom = m_pTreeCtrl->m_hWnd;
        //mHDR.code = NM_RCLICK;
        //mHDR.idFrom = m_pTreeCtrl->GetDlgCtrlID();

        // and send a WM_NOTIFY message to our owner.
        //SendNotify(&mHDR);
    //}

was now comment out.
Why ?????

Hello,

Anyway it is Microsoft related.. You can see same problem using standard CTreeCtrl.
