I'm trying to follow http://doc.qt.io/qtcreator/creator-using-qt-quick-designer.html#loading-placeholder-data by providing a dummydata directory in the root of my project. My project's QML files are in a .qrc file, and I've tried having someModel.qml both in and out of the .qrc file to no effect.

I also tried declaring the model at the same point that I assign it

        model: SomeModel {
            someProperty: foo
        }

and then creating SomeModel.qml, but that also didn't work.
