463 \class QListWidgetItem-
464 \brief The QListWidgetItem class provides an item for use with the-
465 QListWidget item view class.-
466-
467 \ingroup model-view-
468 \inmodule QtWidgets-
469-
470 A QListWidgetItem represents a single item in a QListWidget. Each item can-
471 hold several pieces of information, and will display them appropriately.-
472-
473 The item view convenience classes use a classic item-based interface rather-
474 than a pure model/view approach. For a more flexible list view widget,-
475 consider using the QListView class with a standard model.-
476-
477 List items can be inserted automatically into a list, when they are-
478 constructed, by specifying the list widget:-
479-
480 \snippet qlistwidget-using/mainwindow.cpp 2-
481-
482 Alternatively, list items can also be created without a parent widget, and-
483 later inserted into a list using QListWidget::insertItem().-
484-
485 List items are typically used to display text() and an icon(). These are-
486 set with the setText() and setIcon() functions. The appearance of the text-
487 can be customized with setFont(), setForeground(), and setBackground().-
488 Text in list items can be aligned using the setTextAlignment() function.-
489 Tooltips, status tips and "What's This?" help can be added to list items-
490 with setToolTip(), setStatusTip(), and setWhatsThis().-
491-
492 By default, items are enabled, selectable, checkable, and can be the source-
493 of drag and drop operations.-
494-
495 Each item's flags can be changed by calling setFlags() with the appropriate-
496 value (see Qt::ItemFlags). Checkable items can be checked, unchecked and-
497 partially checked with the setCheckState() function. The corresponding-
498 checkState() function indicates the item's current check state.-
499-
500 The isHidden() function can be used to determine whether the item is-
501 hidden. To hide an item, use setHidden().-
502-
503-
504 \section1 Subclassing-
505-
506 When subclassing QListWidgetItem to provide custom items, it is possible to-
507 define new types for them enabling them to be distinguished from standard-
508 items. For subclasses that require this feature, ensure that you call the-
509 base class constructor with a new type value equal to or greater than-
510 \l UserType, within \e your constructor.-

1144 \class QListWidget-
1145 \brief The QListWidget class provides an item-based list widget.-
1146-
1147 \ingroup model-view-
1148 \inmodule QtWidgets-
1149-
1150 QListWidget is a convenience class that provides a list view similar to the-
1151 one supplied by QListView, but with a classic item-based interface for-
1152 adding and removing items. QListWidget uses an internal model to manage-
1153 each QListWidgetItem in the list.-
1154-
1155 For a more flexible list view widget, use the QListView class with a-
1156 standard model.-
1157-
1158 List widgets are constructed in the same way as other widgets:-
1159-
1160 \snippet qlistwidget-using/mainwindow.cpp 0-
1161-
1162 The selectionMode() of a list widget determines how many of the items in-
1163 the list can be selected at the same time, and whether complex selections-
1164 of items can be created. This can be set with the setSelectionMode()-
1165 function.-
1166-
1167 There are two ways to add items to the list: they can be constructed with-
1168 the list widget as their parent widget, or they can be constructed with no-
1169 parent widget and added to the list later. If a list widget already exists-
1170 when the items are constructed, the first method is easier to use:-
1171-
1172 \snippet qlistwidget-using/mainwindow.cpp 1-
1173-
1174 If you need to insert a new item into the list at a particular position,-
1175 then it should be constructed without a parent widget. The insertItem()-
1176 function should then be used to place it within the list. The list widget-
1177 will take ownership of the item.-
1178-
1179 \snippet qlistwidget-using/mainwindow.cpp 6-
1180 \snippet qlistwidget-using/mainwindow.cpp 7-
1181-
1182 For multiple items, insertItems() can be used instead. The number of items-
1183 in the list is found with the count() function. To remove items from the-
1184 list, use takeItem().-
1185-
1186 The current item in the list can be found with currentItem(), and changed-
1187 with setCurrentItem(). The user can also change the current item by-
1188 navigating with the keyboard or clicking on a different item. When the-
1189 current item changes, the currentItemChanged() signal is emitted with the-
1190 new current item and the item that was previously current.-
