Detailed Description

This proxy model will display only the portion of a tree model with the common ancestor rootIndex.

The functionality is similar to QAbstractItemView::setRootIndex but on the model side

Property Documentation

rootIndex

RootIndexProxyModel::rootIndex

readwrite

This property holds the root index of the model.

Access functions: rootIndex(), setRootIndex()

Notifier signal: rootIndexChanged()

The root index is an index of the source model used as root by all elements of the proxy model
