895 \brief The QComboBox widget is a combined button and popup list.-
896-
897 \ingroup basicwidgets-
898 \inmodule QtWidgets-
899-
900 A QComboBox provides a means of presenting a list of options to the user-
901 in a way that takes up the minimum amount of screen space.-
902-
903 A combobox is a selection widget that displays the current item,-
904 and can pop up a list of selectable items. A combobox may be editable,-
905 allowing the user to modify each item in the list.-
906-
907 Comboboxes can contain pixmaps as well as strings; the-
908 insertItem() and setItemText() functions are suitably overloaded.-
909 For editable comboboxes, the function clearEditText() is provided,-
910 to clear the displayed string without changing the combobox's-
911 contents.-
912-
913 There are two signals emitted if the current item of a combobox-
914 changes, currentIndexChanged() and activated().-
915 currentIndexChanged() is always emitted regardless if the change-
916 was done programmatically or by user interaction, while-
917 activated() is only emitted when the change is caused by user-
918 interaction. The highlighted() signal is emitted when the user-
919 highlights an item in the combobox popup list. All three signals-
920 exist in two versions, one with a QString argument and one with an-
921 \c int argument. If the user selects or highlights a pixmap, only-
922 the \c int signals are emitted. Whenever the text of an editable-
923 combobox is changed the editTextChanged() signal is emitted.-
924-
925 When the user enters a new string in an editable combobox, the-
926 widget may or may not insert it, and it can insert it in several-
927 locations. The default policy is \l InsertAtBottom but you can change-
928 this using setInsertPolicy().-
929-
930 It is possible to constrain the input to an editable combobox-
931 using QValidator; see setValidator(). By default, any input is-
932 accepted.-
933-
934 A combobox can be populated using the insert functions,-
935 insertItem() and insertItems() for example. Items can be-
936 changed with setItemText(). An item can be removed with-
937 removeItem() and all items can be removed with clear(). The text-
938 of the current item is returned by currentText(), and the text of-
939 a numbered item is returned with text(). The current item can be-
940 set with setCurrentIndex(). The number of items in the combobox is-
941 returned by count(); the maximum number of items can be set with-
942 setMaxCount(). You can allow editing using setEditable(). For-
943 editable comboboxes you can set auto-completion using-
944 setCompleter() and whether or not the user can add duplicates-
945 is set with setDuplicatesEnabled().-
946-
947 QComboBox uses the \l{Model/View Programming}{model/view-
948 framework} for its popup list and to store its items. By default-
949 a QStandardItemModel stores the items and a QListView subclass-
950 displays the popuplist. You can access the model and view directly-
951 (with model() and view()), but QComboBox also provides functions-
952 to set and get item data (e.g., setItemData() and itemText()). You-
953 can also set a new model and view (with setModel() and setView()).-
954 For the text and icon in the combobox label, the data in the model-
955 that has the Qt::DisplayRole and Qt::DecorationRole is used. Note-
956 that you cannot alter the \l{QAbstractItemView::}{SelectionMode}-
957 of the view(), e.g., by using-
958 \l{QAbstractItemView::}{setSelectionMode()}.-
