Sql Query with QTreeView - Advice

[johnnyturbo3]

Hi,

I currently have a program that use a QSqlQueryModel to populate a QTableView. I now want to change from QTableView to QTreeView.

I've done some searching for examples and quick fixes, but has left me more confused than anything. So, I understand that I have to build my own data structure using either QStandardItemModel or a proxymodel.

The query that is needed to populate the QTreeView is going to be very large.

Does anyone have advice on what route to take the achieve this?
Thanks
