469 \class QListWidgetItem-
470 \brief The QListWidgetItem class provides an item for use with the-
471 QListWidget item view class.-
472-
473 \ingroup model-view-
474 \inmodule QtWidgets-
475-
476 A QListWidgetItem represents a single item in a QListWidget. Each item can-
477 hold several pieces of information, and will display them appropriately.-
478-
479 The item view convenience classes use a classic item-based interface rather-
480 than a pure model/view approach. For a more flexible list view widget,-
481 consider using the QListView class with a standard model.-
482-
483 List items can be inserted automatically into a list, when they are-
484 constructed, by specifying the list widget:-
485-
486 \snippet qlistwidget-using/mainwindow.cpp 2-
487-
488 Alternatively, list items can also be created without a parent widget, and-
489 later inserted into a list using QListWidget::insertItem().-
490-
491 List items are typically used to display text() and an icon(). These are-
492 set with the setText() and setIcon() functions. The appearance of the text-
493 can be customized with setFont(), setForeground(), and setBackground().-
494 Text in list items can be aligned using the setTextAlignment() function.-
495 Tooltips, status tips and "What's This?" help can be added to list items-
496 with setToolTip(), setStatusTip(), and setWhatsThis().-
497-
498 By default, items are enabled, selectable, checkable, and can be the source-
499 of drag and drop operations.-
500-
501 Each item's flags can be changed by calling setFlags() with the appropriate-
502 value (see Qt::ItemFlags). Checkable items can be checked, unchecked and-
503 partially checked with the setCheckState() function. The corresponding-
504 checkState() function indicates the item's current check state.-
505-
506 The isHidden() function can be used to determine whether the item is-
507 hidden. To hide an item, use setHidden().-
508-
509-
510 \section1 Subclassing-
511-
512 When subclassing QListWidgetItem to provide custom items, it is possible to-
513 define new types for them enabling them to be distinguished from standard-
514 items. For subclasses that require this feature, ensure that you call the-
515 base class constructor with a new type value equal to or greater than-
516 \l UserType, within \e your constructor.-

1146 \class QListWidget-
1147 \brief The QListWidget class provides an item-based list widget.-
1148-
1149 \ingroup model-view-
1150 \inmodule QtWidgets-
1151-
1152 QListWidget is a convenience class that provides a list view similar to the-
1153 one supplied by QListView, but with a classic item-based interface for-
1154 adding and removing items. QListWidget uses an internal model to manage-
1155 each QListWidgetItem in the list.-
1156-
1157 For a more flexible list view widget, use the QListView class with a-
1158 standard model.-
1159-
1160 List widgets are constructed in the same way as other widgets:-
1161-
1162 \snippet qlistwidget-using/mainwindow.cpp 0-
1163-
1164 The selectionMode() of a list widget determines how many of the items in-
1165 the list can be selected at the same time, and whether complex selections-
1166 of items can be created. This can be set with the setSelectionMode()-
1167 function.-
1168-
1169 There are two ways to add items to the list: they can be constructed with-
1170 the list widget as their parent widget, or they can be constructed with no-
1171 parent widget and added to the list later. If a list widget already exists-
1172 when the items are constructed, the first method is easier to use:-
1173-
1174 \snippet qlistwidget-using/mainwindow.cpp 1-
1175-
1176 If you need to insert a new item into the list at a particular position,-
1177 then it should be constructed without a parent widget. The insertItem()-
1178 function should then be used to place it within the list. The list widget-
1179 will take ownership of the item.-
1180-
1181 \snippet qlistwidget-using/mainwindow.cpp 6-
1182 \snippet qlistwidget-using/mainwindow.cpp 7-
1183-
1184 For multiple items, insertItems() can be used instead. The number of items-
1185 in the list is found with the count() function. To remove items from the-
1186 list, use takeItem().-
1187-
1188 The current item in the list can be found with currentItem(), and changed-
1189 with setCurrentItem(). The user can also change the current item by-
1190 navigating with the keyboard or clicking on a different item. When the-
1191 current item changes, the currentItemChanged() signal is emitted with the-
1192 new current item and the item that was previously current.-
