You need to override the object's canDrag() method, and have it return 
false. If you want all objects of that class to be undraggable, you'd 
want to subclass, e.g.

	class Cone < Fox::FXGLCone
		def canDrag
			false
		end
	end

or if it's just one particular object that you don't want to be 
draggable:

	cone = FXGLCone.new(...)
	def cone.canDrag; false; end

Hope this helps,
