    AbstractFileDialog provides only the API for implementing a file dialog.
    The implementation (e.g. a Window or preferably an Item, in case it is
    shown on a device that doesn't support multiple windows) can be provided as
    \l implementation, which is the default property (the only allowed child
    element).

    The QQuickFileDialog class is a concrete subclass of
    \l QQuickAbstractFileDialog, but it is abstract from the QML perspective
    because it needs to enclose a graphical implementation. It exists in order
    to provide accessors and helper functions which the QML implementation will
    need.
