Unselectable Shape

I want to draw shapes that are not selectable at all. The solution I came up with is to derive UnselectableShape class from AIS_Shape and implement an empty ComputeSelection method. Is this an exceptable method?


class UnselectableShape : public AIS_Shape
{
public:
UnselectableShape(const TopoDS_Shape& shap) : AIS_Shape(shap) {}

protected:
void ComputeSelection(const Handle(SelectMgr_Selection)&, const Standard_Integer)
{
}
};
