How i diplay the bodies wireframe?

What code i have to write to display the bodies wireframe?

once:

OgreNewt::Debugger::getSingleton().init( mSceneManager );

and whenever you want to see the bodies (maybe each frame?)

OgreNewt::Debugger::getSingleton().drawLines( mOgreNewtWorld );



and to hide the last lines drawn:

OgreNewt::Debugger::getSingleton().hideLines();


Thanks man you rock!
