Toolbox Item Widgets (Item-Based)

The Item Widgets (Item-Based) toolbox contains the following items:

List Widget: drag and drop this item onto your form to create a list widget. The ListWidget class provides an item-based list widget. ListWidget is a convenience class that provides a list view similar to the one supplied by ListView, but with a classic item-based interface for adding and removing items.
Tree Widget: drag and drop this item onto your form to create a tree widget. The TreeWidget class provides a tree view that uses a predefined tree model.
Table Widget: drag and drop this item onto your form to create a table widget. The TableWidget class provides an item-based table view with a default model. Table widgets provide standard table display facilities for applications. If you want a table that uses your own data model you should use TableView rather than this class.
