> Hello:

> I came across a use case where I wanted to return a QAbstractListModel from
> a Q_INVOKABLE in a C++ QObject based class.

> The explicit constructor for QAbstractListModel requires a construction of

> Model instance.

> I imagine the explicit constructor suppresses a lot of careless bugs.

> Q_INVOKABLE MyQAbstractListModel* getmodel(void)

>    return (&gmodel) ;

> The QML engine is a bit confused by receiving a pointer to the model
> instead of the entire model itself.

> QML Output:
>
> qrc:/main.qml:48: Error: Unknown method return type: MyQAbstractListModel*

> Maybe someone on the dev list has an idea on how to return a pointer to a
> model from Q_INVOKABLE or maybe someone doing current builds can add a
> AbstractListModel pointer to the known set or method return types in the
> framework for Qt 5.5.x

> Anybody's comments appreciated...
