    Description

      It will be nice if we can create Q_GADGET objects in QML not only to use them.

      I'll paste Simon's reply here:

      No objection per-se, but we'd have to figure out some details. For example declarative instantiation is not an object, as the ownership rules do not comply with QObject. That would leave us with a JavaScript
      constructor function, replacing Qt.point(...) for example. But then we'd have to comply with the namespace rules, so we'd have

          qmlRegisterGadget<MyGadget>("MyModule", "ThatName", 1, 0);

      and then

          import MyModule 1.0

      and in expressions we'd have

          var g = new ThatName();

      and the same for a namespaced import:

          import MyModule 1.0 as Foo
    var g = new Foo.ThatName();

      It's a bit of work to do, but I don't see a problem in principle.

      I'm adding also :

          import MyModule 1.0 as Foo
    property Foo.ThatName name
