Subclassing

When subclassing QTableWidgetItem to provide custom items, it is possible to define new types for them so that they can be distinguished from standard items. The constructors for subclasses that require this feature need to call the base class constructor with a new type value equal to or greater than UserType.

See also QTableWidget, Model/View Programming, QListWidgetItem, and QTreeWidgetItem.

Member Type Documentation

enum QTableWidgetItem::ItemType

This enum describes the types that are used to describe table widget items.

You can define new user types in QTableWidgetItem subclasses to ensure that custom items are treated specially.

See also type().
