From QListViewItem Class Reference:
The QListViewItem class implements a list view item.
A list view item is a multi-column object capable of displaying itself in a QListView.
The easiest way to use QListViewItem is to construct one with a few constant strings, and either a QListView or another QListViewItem as parent.
(void) new QListViewItem( listView, "Column 1", "Column 2" );
(void) new QListViewItem( listView->firstChild(), "A", "B", "C" );

We've discarded the pointers to the items since we can still access them via their parent listView. By default, QListView sorts its items; this can be switched off with QListView::setSorting(-1).
The parent must be another QListViewItem or a QListView. If the parent is a QListView, the item becomes a top-level item within that QListView. If the parent is another QListViewItem, the item becomes a child of that list view item.

it is not working that means the childs are not added to the columns.
