How to get the selected subshapes

Hello

I can change the selection mode and select subshapes, but how do I get the selected subshapes, e.g. faces or vertices?

I've tried this approach below, but now I'm stuck.

Any help much appreciated :)

int previousSelMode = 0;
void SetSelectionMode(int selectionMode)
{
myAISContext()->CloseAllContexts();
myAISContext()->OpenLocalContext(Standard_False);
//myAISContext()->OpenLocalContext();
switch (selectionMode)
{
case 0:
myAISContext()->ActivateStandardMode(TopAbs_SOLID);
break;
case 1:
myAISContext()->ActivateStandardMode(TopAbs_VERTEX);
break;
case 2:
myAISContext()->ActivateStandardMode(TopAbs_EDGE);
break;
case 3:
myAISContext()->ActivateStandardMode(TopAbs_WIRE);
break;
case 4:
myAISContext()->ActivateStandardMode(TopAbs_FACE);
break;
case 5:
myAISContext()->ActivateStandardMode(TopAbs_SHELL);
break;
case 6:
myAISContext()->ActivateStandardMode(TopAbs_SOLID);
break;
case 7:
myAISContext()->ActivateStandardMode(TopAbs_COMPSOLID);
break;
case 8:
myAISContext()->ActivateStandardMode(TopAbs_COMPOUND);
break;
}

AIS_ListOfInteractive objects;
myAISContext()->DisplayedObjects (objects);
AIS_ListIteratorOfListOfInteractive iobject (objects);
while (iobject.More ())
{
myAISContext()->Deactivate(iobject.Value(), previousSelMode);
myAISContext()->Activate(iobject.Value(), selectionMode);

myAISContext()->SetHilightColor(Quantity_NameOfColor::Quantity_NOC_WHITE);
myAISContext()->SetTransparency(iobject.Value(), 0.3);
//myAISContext()->Redisplay(iobject.Value());

myAISContext()->Display(iobject.Value(), 1, -1, Standard_True, Standard_True);
Handle(StdSelect_FaceFilter) Fil1 = new StdSelect_FaceFilter(StdSelect_Revol);
Handle(StdSelect_FaceFilter) Fil2 = new StdSelect_FaceFilter(StdSelect_Plane);
myAISContext()->AddFilter(Fil1);
myAISContext()->AddFilter(Fil2);

iobject.Next ();
}
previousSelMode = selectionMode;
}

void Select(void)
{
if (!myAISContext().IsNull())
{
AIS_StatusOfPick s = myAISContext()->Select();
}
}

NativeWrapper^ GetSelectedShape()
{
NativeWrapper ^f;
if (!myAISContext().IsNull())
{
for (myAISContext()->InitSelected(); myAISContext()->MoreSelected(); myAISContext()->NextSelected())
{
if (myAISContext()->HasSelectedShape())
{
const TopoDS_Shape& shape = myAISContext()->SelectedShape();
TopoDS_Shape* retVal = new TopoDS_Shape(shape);
f = gcnew NativeWrapper(retVal);
}
else
{
Handle_AIS_InteractiveObject aniobj = myAISContext()->Interactive();
// to be able to use the picked interactive object

}
}
}
return f;
}
