The documentation for VisualDataModel is not very clear about how to use rootIndex statically.

In my case, I wanted to expose a QAbstractListModel to QML. This requires that you set rootIndex, but it was not readily apparent how I should do so.

It seems like I should set it as follows, but I am still not quite sure.

ListView {
model: VisualDataModel {
model: myExposedQAbstractListModel
rootIndex: modelIndex(0)
}
}
