     CXTPDockingPaneInfoList& paneList = m_paneManager.GetPaneList();
    for (POSITION pos = paneList.GetHeadPosition(); pos;)
    {
        XTP_DOCKINGPANE_INFO& dpi = paneList.GetNext(pos);
        if (dpi.pPane != NULL && dpi.pPane->IsHidden())
        {
            CXTPDockingPaneAutoHidePanel* pPaneAuto = (CXTPDockingPaneAutoHidePanel*)dpi.pPane;
            XTPDockingPaneDirection direction = pPaneAuto->GetDirection();

            //if( pPaneBase->GetType() == xtpPaneTypeAutoHidePanel )
            {
