示例1: setEdit

    if (ModNum == ViewProvider::Default) {
        // get the properties from the mirror feature
        Part::Mirroring* mf = static_cast<Part::Mirroring*>(getObject());

        Base::Vector3f cbox((float)cent.x,(float)cent.y,(float)cent.z);
        base = cbox.ProjToPlane(base, norm);

        // setup the graph for editing the mirror plane
        SoTransform* trans = new SoTransform;

        // Now we replace the SoTransform node by a manipulator
        // Note: Even SoCenterballManip inherits from SoTransform
        // we cannot use it directly (in above code) because the
        // translation and center fields are overridden.
