Hi Wanger, Right now osgWidget is designed as a 2D interface, rather than a full 3D object so the objects can't be moved around as flexibly as normal 3D objects in the scene.
The author of osgWidget, Jeremy Moles, has discussed work that has been undertaking to refactor osgWidget to allow the widgets to be used in more flexible way - including in a full 3D scene. Please check through the osg-users archive for discussion on this. Robert.
