[C#]

ICommand cmd = new ControlsGlobeOrbitalFlyToolClass();

            cmd.OnCreate(axGlobeControl1.Object);
            if (cmd.Enabled) axGlobeControl1.CurrentTool = cmd as ITool;
            ITool tool = cmd as ITool;

            //显示指北针
            axGlobeControl1.GlobeViewer.NorthArrowEnabled = true;
            axGlobeControl1.GlobeDisplay.RefreshViewers();

[Qt C++]

    ICommandPtr cmd(CLSID_ControlsGlobeOrbitalFlyTool);
   IDispatchPtr disp;
   m_IpGlobeControl->get_Object(&disp);
   cmd->OnCreate(disp);
   VARIANT_BOOL bEnable;
   hr = cmd->get_Enabled(&bEnable);
   if(bEnable)
   {
       m_IpGlobeControl->putref_CurrentTool(IToolPtr(cmd));
   }

   //显示指北针
   m_IpGlobeViewer->put_NorthArrowEnabled(VARIANT_TRUE);
   M_IpGlobeDisplay->RefreshViewers();

指北针只有在当前工具是OrbitalFlyTool时才会显示
