[osg-users] About viewer.addEventHandler(new PickHandler())?

[小 杨]

Hi everyone:
   
  void PickHandler::pick(const osgGA::GUIEventAdapter& ea, osgViewer::Viewer* 
viewer)
 {
  osg::Node* scene = viewer->getSceneData();
  if (!scene) return;
   
     if(ea.getEventType() == osgGA::GUIEventAdapter::PUSH )
     {
             scene->setUpdateCallback(new RotateCallBack());
     }
   
  }
   
   
  My question is  when next  mouse PUSH , scene->setUpdateCallback(new 
RotateCallBack())  call  again and new a  RotateCallBack object.
  But can last time RotateCallBack  object is auto-delete?
   
  Thanks in advance!
