Hello Graham, You can use the contextMenuPolicy Qt::CustomContextMenu. In that case, when your QTreeView receives a right-click, it sends a signal contextMenuRequested(QPoint) that you can connect to a slot. In that slot, you are able to know which item has been clicked through QTreeView::indexAt(QPoint). You can then compose your context menu (use QMenu) as needed, and show it with QMenu::exec().
If you already subclassed QTreeView for a reason or another, there is another way: leave the contextMenuPolicy as is and reimplement the contextMenuEvent method. From there on it's the same as with the 1st method (retrieve clicked index, compose menu and execute it).
