In Web Inspector's console ,i input " QObject.all() ",but it return

QObject.all()
Error: cannot call all(): unknown type QObjectList' line: 2 message: "cannot call all(): unknown type QObjectList'"
stack: "all@[native code]↵eval code↵eval@[native code]↵evaluate@[native code]↵_evaluateOn↵_evaluateAndWrap↵evaluate"
proto: Error

I experience the same problem, maybe even worse, because if I open the Javascript console through the inspector and I try to access the method returning the QObjectList it works Perfectly!
Any idea?

Hi,

I'm not 100% sure, but try using QQmlListProperty instead of QObjectList: http://qt-project.org/doc/qt-5/qtqml-referenceexamples-properties-example.html
