Synopsis

Functions

Virtual functions

Detailed Description

A QListWidgetItem represents a single item in a QListWidget . Each item can hold several pieces of information, and will display them appropriately.

The item view convenience classes use a classic item-based interface rather than a pure model/view approach. For a more flexible list view widget, consider using the QListView class with a standard model.

List items can be inserted automatically into a list, when they are constructed, by specifying the list widget:

new QListWidgetItem(tr("Hazel"), listWidget);

Alternatively, list items can also be created without a parent widget, and later inserted into a list using insertItem() .

List items are typically used to display text() and an icon() . These are set with the setText() and setIcon() functions. The appearance of the text can be customized with setFont() , setForeground() , and setBackground() . Text in list items can be aligned using the setTextAlignment() function. Tooltips, status tips and “What’s This?” help can be added to list items with setToolTip() , setStatusTip() , and setWhatsThis() .

By default, items are enabled, selectable, checkable, and can be the source of drag and drop operations.

Each item’s flags can be changed by calling setFlags() with the appropriate value (see ItemFlags ). Checkable items can be checked, unchecked and partially checked with the setCheckState() function. The corresponding checkState() function indicates the item’s current check state.

The isHidden() function can be used to determine whether the item is hidden. To hide an item, use setHidden() .

Subclassing

When subclassing QListWidgetItem to provide custom items, it is possible to define new types for them enabling them to be distinguished from standard items. For subclasses that require this feature, ensure that you call the base class constructor with a new type value equal to or greater than UserType , within your constructor.

class QListWidgetItem([listview=None[, type=Type]])

QListWidgetItem(icon, text[, listview=None[, type=Type]])

Constructs an empty list widget item of the specified type with the given parent . If parent is not specified, the item will need to be inserted into a list widget with insertItem() .

This constructor inserts the item into the model of the parent that is passed to the constructor. If the model is sorted then the behavior of the insert is undetermined since the model will call the '<' operator method on the item which, at this point, is not yet constructed. To avoid the undetermined behavior, we recommend not to specify the parent and use insertItem() instead.

type()

Constructs an empty list widget item of the specified type with the given icon , text and parent . If the parent is not specified, the item will need to be inserted into a list widget with insertItem() .

This constructor inserts the item into the model of the parent that is passed to the constructor. If the model is sorted then the behavior of the insert is undetermined since the model will call the '<' operator method on the item which, at this point, is not yet constructed. To avoid the undetermined behavior, we recommend not to specify the parent and use insertItem() instead.

type()

Constructs a copy of other . Note that type() and listWidget() are not copied.

This function is useful when reimplementing clone() .
