Multiple data in different columns

I have a QListWidget and am trying to put data into two different columns, for example:             QTreeWidgetItem *ItemId = new QTreeWidgetItem();               QTreeWidgetItem *ItemName = new QTreeWidgetItem();               ItemId->setText(0, "12");               ItemName->setText(1, "Hello World");               ui->MyTreeWidget->addTopLevelItem(ItemId);               ui->MyTreeWidget->addTopLevelItem(ItemName); But not getting it right.
