Pointers are not converted to QVariant for method call

Arguments for methods are not accepted if you try to pass the pointer to QObject/QGraphicsItem-derived class. For example:

>>
function setModel(aModel)

{ lv.model = aModel; }

ListModel

{ id: lm }

ListView

{ id: lv }

Component.onCompleted: lv.setModel(lm);
>>

will cause

>>
test.qml:15: TypeError: incompatible type of argument(s) in call to setModel(); candidates were
setModel(QVariant)
