    • Resolution: Unresolved
    • P2: Important
    • None
    • 5.0.0
    • Quick: Core Declarative QML
    • None

    Description

      This would be useful not only for Qt Quick's own items (e.g. views) to take advantage of, but also user code. I don't know what the solution would look like, but this can be brainstormed here.
