I use the QSGNode API already. But this only works for nodes I instantiate
myself, right?


I'm looking for a way to manipulate a transform node so that any child item
instantiated in QML will be affected.


MyAnimatedNode {

   Text {

      ...

   }

   Image {

      ...

   }

}


If MyAnimatedNode was a spinner like in the "threadedanimation" example,
the text and image would not spin along.


I did find a way though, but it does abuse the API. I can use
QSGNode::parent to find the parent transform node (the "itemNode"?) of a
dummy node I create. I can then manipulate the itemNode's transform similar
to what the animator classes do. Not that I'll ship anything actually doing
that.


Cheers,

Ola
