[Qt-qml] reparent on destruction

[Pekka.E.Jokela at nokia.com]

Hi,
Is there a way to re-parent a child item on the destruction?

I would like to re-use a QML item in several views, because the item consumes a lot of memory and takes time to initialize. When a view becomes active, the item is re-parented to that view. This way, the  transformations and z-order of the re-cycled item matches the view. Now the problem arises when the active view is destroyed at run-time. We would need to re-parent the recycled item to the next visible view on the view stack. How this can be done?

View {
    Component.onDestruction {
       recycledChild.parent = newView
    }
}

Problem with this approach is that the recycledChild is, at the time of the deletion, a child of the deleted view and the destruction order is undefined i.e. the child items are most likely destroyed already.

One option is implement the View in c++ and re-parent in the destructor, but then we cannot "derive" from QML items like Page element from qt-components.

-Pekka
