OgreNewt and pickingup objects

hi guys,

I want to do some collision detection and object picking in my application with Ogre. I used ray query but the problem is that RaySceneQuery just works on BoundingBox so I could not detect opened-doors or the like.
And I move to OgreNewt for these problems. But I'm just a newbie.

So could anyone give me some points please?

thanks in advance

OgreNewt comes with several demo examples, and several of those implement dragging objects with the mouse, which is done with OgreNewt::Raycast, look there for examples.
