[Interest] Non rectangular clipPath for QQuickItems

I'm porting our Quick 1 application to Quick 2.
In our application we had an triangle shaped item with a clipping path. 
All child Items in QML (e.g. our Buttons) will be clipped to that 
triangular shape

//in C'tor:
this->setFlag(QGraphicsItem::ItemHasNoContents, false);
this->setFlag(QGraphicsItem::ItemClipsChildrenToShape, true);

//in paint just drawing the triangle

but the most important thing was overriding the QGraphicsItem::shape() 
method which returned the triangular shape which Quick 1 would use for 

But how would I do that with a QQuickItem?
I've ported the drawing of the triangle by overriding 
There I'd return a QSGClipNode which would perform the nessesary 
clipping, but this will only clip the SG-children. But QML child Items
won't be scene graph children.

Does anyone have a solution?
