I want to fix the Trihedron.

HI :) I am developing in .net.

1. Trihedron continues to move. I want to fix it.

2. I'd like to change the location of Trihedron.

3. I want to change the location of the ViewCube.

code

//ViewCube 
        Handle(AIS_ViewCube) aisViewCube = new AIS_ViewCube;
        aisViewCube->SetBoxColor(Quantity_NOC_GRAY75);
        //aisViewCube->SetFixedAnimationLoop(false);
        aisViewCube->SetDrawAxes(false);
        aisViewCube->SetSize(55);
        aisViewCube->SetFontHeight(12);
        aisViewCube->SetTransformPersistence(
            new Graphic3d_TransformPers(
                Graphic3d_TMF_TriedronPers,
                Aspect_TOTP_LEFT_UPPER,
                Graphic3d_Vec2i(45, 85)));
        myAISContext()->Display(aisViewCube, false);

//aisTrihedron
        Handle(Geom_Axis2Placement) axis = new Geom_Axis2Placement(gp::XOY());
        Handle(AIS_Trihedron) aisTrihedron = new AIS_Trihedron(axis);
        aisTrihedron->SetDatumDisplayMode(Prs3d_DM_WireFrame);
        aisTrihedron->SetDrawArrows(true);

        aisTrihedron->Attributes()->DatumAspect()->LineAspect(Prs3d_DP_XAxis)->SetWidth(2.5);
        aisTrihedron->Attributes()->DatumAspect()->LineAspect(Prs3d_DP_YAxis)->SetWidth(2.5);
        aisTrihedron->Attributes()->DatumAspect()->LineAspect(Prs3d_DP_ZAxis)->SetWidth(2.5);
        aisTrihedron->SetDatumPartColor(Prs3d_DP_XAxis, Quantity_NOC_RED2);
        aisTrihedron->SetDatumPartColor(Prs3d_DP_YAxis, Quantity_NOC_GREEN2);
        aisTrihedron->SetDatumPartColor(Prs3d_DP_ZAxis, Quantity_NOC_BLUE2);
        aisTrihedron->SetLabel(Prs3d_DP_XAxis, "");
        aisTrihedron->SetLabel(Prs3d_DP_YAxis, "");
        aisTrihedron->SetLabel(Prs3d_DP_ZAxis, "");

        aisTrihedron->SetTransformPersistence(
            new Graphic3d_TransformPers(Graphic3d_TMF_ZoomPers, axis->Ax2().Location()));
        aisTrihedron->Attributes()->SetZLayer(Graphic3d_ZLayerId_Topmost);
        aisTrihedron->SetInfiniteState(true);
        myAISContext()->Display(aisTrihedron, Standard_False);

This is the current screen.
