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.
