CXTTreeCtrl Context Menu : Hello, Sounds like you may...

Hello,

Sounds like you may be using a CXTTreeView? If so there is a bug in MFC that prevents WM_CONTEXTMENU from getting fired correctly for a CTreeView or CListView derived class.

Even if you are not using a CTreeView you should be able to use the following code as a work around, add a WM_RBUTTONDOWN handler in place of your WM_CONTEXTMENU handler, for example:

BEGIN_MESSAGE_MAP(CTestAppView, CTreeView)
    //{{AFX_MSG_MAP(CTestAppView)
    ON_WM_RBUTTONDOWN()
    //}}AFX_MSG_MAP
END_MESSAGE_MAP()
void CTestAppView::OnRButtonDown(UINT nFlags, CPoint point) 
{
    CPoint pt = point;
    ClientToScreen(&pt);
    
    if (pt.x == -1 && pt.y == -1)
    {
        // keystroke invocation
        CRect rect;
        GetClientRect(rect);
        ClientToScreen(rect);
        
        pt = rect.TopLeft();
        pt.Offset(5, 5);
    }
    
    CMenu menu;
    VERIFY(menu.LoadMenu(CG_IDR_POPUP_TEST_APP_VIEW));
    
    CMenu* pPopup = menu.GetSubMenu(0);
    ASSERT(pPopup != NULL);
    CWnd* pWndPopupOwner = this;
    
    while (pWndPopupOwner->GetStyle() & WS_CHILD)
        pWndPopupOwner = pWndPopupOwner->GetParent();
    
    pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, pt.x, pt.y,
        pWndPopupOwner);
    
    CTreeView::OnRButtonDown(nFlags, point);
}

Hope this helps.

CXTTreeCtrl Context Menu : I have a CXTTreeCtrl where I want...

I have a CXTTreeCtrl where I want to right click on a node and have functions listed on that node.

I added a function on the command "WM_CONTEXTMENU" and that works, except you need to double right-click. I can't seem to figure out why that is, nor do I see any other ways to bring up the context menu.

Any ideas why WM_CONTEXTMENU requires a double right click?

Thanks

Jeff
