I took Konrad Rosenbaums suggestion and used QStandardItemModel. From 
the docs I took something like this :

     QStandardItemModel *treeModel = new QStandardItemModel();
     QStandardItem *parentItem = treeModel->invisibleRootItem();

     for (int i = 0; i < 4; ++i) {
         QStandardItem *item = new QStandardItem(QString("item %0").arg(i));
         parentItem->appendRow(item);
         parentItem = item;
     }

which works. Then, because I wanted checkboxes, I did this, which also 
works, but does not create a tree:

     for (int i = 0; i < 4; ++i) {
         QList<QStandardItem *> items;
         items.append(new QStandardItem(QString("item %0").arg(i)));
         QStandardItem *itemX = new QStandardItem();
         itemX->setCheckable(true);
         items.append(itemX);

         parentItem->appendRow(items);
     }

For the life of me I can't figure out how to make it a hierarchy (the 
equivalent of "parentItem = item;") like the first example. Any one take 
pity?

Thanks for the previous replies and definitely no offence taken.
