Hi Anthony,
Please confirm that I got correctly the problem.
You have a list ListA with the columns A1, A2, A3 and a list ListB with the columns A1, B1, B2, B3 and you want to combine these 2 lists and show them in QListView as follwings
A1 A2 A3 B1 B2 B3
The List B is a child of the List A and links to the lIst A through the column A1.
