There are no interface to control size of handles , only change the source code and rebuild vtk .  
But in python wrappers, it provide  
// plane\_widget-\>SetTubing(false);  
// plane\_widget-\>SetOutlineTranslation(true);  
// plane\_widget-\>SetOriginTranslation(true);  
// plane\_widget-\>SetDrawPlane(false);  
I don’t know why . I am finding it out.
