If you want a simple list then use a QListWidget or QListView.
If you want a multi-column table then use a QTableWidget or QTableView.
If you want a tree structure then use a QTreeWidget or QTreeView.

Each xWidget includes an internal data model and the xView classes need an external model. Each xWidget is-a xView and all can respond to users clicking, double clicking etc. All follow the Model/View Programming approach.

The documentation describes how to use theses classes and even link to examples like the Config Dialog Example
