I tried by best and I found a way to solve thi problem.
The idea is:
First see the scene structure:

SceneRoot
Teapot01 Box01

Teapot01 and Box01 are the children of SceneRoot.
When I select Teapot01, the osgManipulator::selection (I call it in my
program Selection) set Teapot01 as one if its children.
Then I find all the parents of Teapot01, in this example, is SceneRoot and
Selection.
Then I replace the Teapot01 child of SceneRoot with Selection. Now the scene
structure is:

SceneRoot
Selection  Box01
Teapot01

And then I connect the dragger with Selection. All things go right.
When Box01 is selected, I replace the Selection child of SceneRoot with
Teapot01 and calculate the matrix of Teapot01.
The matrix of Selection is also reset. Then repeat the above steps to make
Box01 dragable.

My demo program and test scene is attached. If you have better ideas, please
tell me! Thanks in advanced!

 Hi,


 Can you send the osgmanipulator.cpp modified and your scene to test?

  I know why. root should add an Child include the scene.
 
  But another question. I can drag the Teapot01, but the whole scene now
  has two Teapot. Then how can I fix it?

   Hi, Robert

   I tried to modify it as I want to move one object in the scene but the
   whole scene. I tried to do this in addDraggerToScene function:
  
   osg::Node* addDraggerToScene(osg::Node* scene,

   {

  selection-addChild(selectedObject);
  
  osgManipulator::Dragger* dragger = createDragger(name);
  
  osg::Group* root = new osg::Group;
  root-addChild(dragger);
  root-addChild(selection);
  root-addChild(createHUD());
  
  float scale = selectedObject-getBound().radius() * 1.6;
  dragger-setMatrix(osg::Matrix::scale(scale, scale, scale) *
  
   osg::Matrix::translate(selectedObject-getBound().center()));
  cmdMgr-connect(*dragger, *selection);
  
  return root;
   }
  
  
   And here my scene has two objects, one teapot, one box. But when I run
 
   the program, I see only the Teapot01 which really can drag and move,
   but the box is lost!
   I don't know how to only move one object in the scene. Please give me
   some ideas. Thanks.
