[Development] Q_INVOKABLE QAbstractListModel

[mark diener]

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
these classes that forces the Q_INVOKABLE to return a pointer to the List
Model instance.

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

But this usage is not currently possible:

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...
