Easier way to find (visual) position of QModelIndex in QTreeView

I'm interested in calculating the physical position of a node in QTreeV开发者_StackOverflow中文版iew and can't find a way to do this (other than calculating it myself, which is cumbersome and error prone given the robustness of QTreeView).

There's a method in QAbstractItemView that does exactly what I needed:

The signature is:

virtual QRect visualRect ( const QModelIndex & index ) const
