Bill: I thought I would do a brain dump on what I learned.
If your data is bound by the roleNames() mechanism, then the dataChanged( ) function works greatl If your data is retrieved by INVOKABLE functions, then you need to call the following: QModelIndex gi = QModelIndex() ; beginInsertRows(gi,gnrow,gnrow); endInsertRows(); beginRemoveRows(gi,gnrow,gnrow); endRemoveRows(); This will force the listview to drop and re-create the component in the delegate. Thanks for your feedback.
