How to iterate among the QListWidgetItems of a QListWidget ?

I have an horizontal QListView that shows multiple thumbnails.
For different reasons, i must be able to move the selection from the currently selected item to the one immediately to his left or right.

In other words, i must find the previous or next QListViewItem in relation to the currently selected one.

ui->listWidget->currentItem()->nextItem()->selected(true);	// This of course, doesn't work !!!!


Thanks !
