Hello, Alejandro. I suggest switching to QListView with a model derived from QAbstractListModel. In your case this method should be quite similar to QListWidget-based one in terms of code complexity, but is somewhat more flexible and, probably, a bit faster because of removing an abstraction layer formed by QListWidget stuff around QListView&Co.
