Your interpretation is correct. Internally the item stores multiple
entries. It contains, pixmaps, fonts, strings, colors and also user data.
There is a setData():
http://doc.trolltech.com/qtjambi-4.4/html/com/trolltech/qt/gui/QListWidgetItem.html#setData(int,%20java.lang.Object)
You specify the role as an integer (values in
com.trolltech.qt.core.Qt.ItemDataRole) and the object to store.
