Question

I have a CFormView, and a child CListCtrl control. I can handle
accelerator events, like Ctrl+C, Ctrl+V … in CFormView without
problem, by defining below message handler:

    ON_COMMAND(ID_EDIT_COPY, &CMyFormView::OnEditCopy) 

Now I want my CListCtrl handle these commands differently. I want to
implement OnEditCopy in CListCtrl class, rather than implement logic
in the view class. How can I pass the accelerator events from CView to
child control, when CListCtrl is on focus? I tried like:

    ON_CONTROL_REFLECT(ID_EDIT_COPY, &CMyListCtrl::OnEditCopy) 

But it doesn’t work.

Use same ON_COMMAND macro in CMyListCtrl.

  ON_COMMAND(ID_EDIT_COPY, &CMyListCtrl::OnEditCopy)  

All you have to do is overriding OnCmdMsg method.

BOOL CMyFormView::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
    if (GetFocus() == m_myListCtrl
        && m_myListCtrl->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
        return TRUE;
    return CMyFormView::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}

(m_myListCtrl is the CMyListCtrl instance pointer.)

This make all WM_COMMAND message first handled in m_myListCtrl if its the focus window.
