QQuickDeliveryAgent delivers events to a tree of Qt Quick Items, beginning with the given root item, which is usually QQuickWindow::rootItem() but may alternatively be embedded into a Qt Quick 3D scene or something else.

Handle ev on behalf of this delivery agent's window or subscene.
This is the usual main entry point for every incoming event: QQuickWindow::event() and QQuick3DViewport::forwardEventToSubscenes() both call this function.
Reimplemented from QObject.

| QQuickDeliveryAgent::Transform * QQuickDeliveryAgent::sceneTransform | ( | ) | const |
Returns the object that was set in setSceneTransform(): a functor that transforms from scene coordinates in the parent scene to scene coordinates within this DA's subscene, or null if none was set.
