I'm not sure if there's a better way but I do it like this:

* My app has an empty page stack

* There's a

Connection {
  target: ContentHub
  onExportRequested: pageStack.push(SomePage.qml, {shareMode: true})
}

* And a

Timer {
  interval: 1
  running: true
  repeat: false
  onTriggered: {
    if (pageStack.depth == 0)
      pageStack.push(SomePage.qml, {shareMode: false})
  }
}

This is everything else but elegant, but seems to do. I've talked to
Ken about this already some time back. IMO there should be a property
on the ContentHub object that indicates the state.

Anyhow, this above solution words reasonably well for me.

Here's the code:

Hope this helps,
