888 \class QComboBox-
889 \brief The QComboBox widget is a combined button and popup list.-
890-
891 \ingroup basicwidgets-
892 \inmodule QtWidgets-
893-
894 A QComboBox provides a means of presenting a list of options to the user-
895 in a way that takes up the minimum amount of screen space.-
896-
897 A combobox is a selection widget that displays the current item,-
898 and can pop up a list of selectable items. A combobox may be editable,-
899 allowing the user to modify each item in the list.-
900-
901 Comboboxes can contain pixmaps as well as strings; the-
902 insertItem() and setItemText() functions are suitably overloaded.-
903 For editable comboboxes, the function clearEditText() is provided,-
904 to clear the displayed string without changing the combobox's-
905 contents.-
906-
907 There are two signals emitted if the current item of a combobox-
908 changes, currentIndexChanged() and activated().-
909 currentIndexChanged() is always emitted regardless if the change-
910 was done programmatically or by user interaction, while-
911 activated() is only emitted when the change is caused by user-
912 interaction. The highlighted() signal is emitted when the user-
913 highlights an item in the combobox popup list. All three signals-
914 exist in two versions, one with a QString argument and one with an-
915 \c int argument. If the user selects or highlights a pixmap, only-
916 the \c int signals are emitted. Whenever the text of an editable-
917 combobox is changed the editTextChanged() signal is emitted.-
918-
919 When the user enters a new string in an editable combobox, the-
920 widget may or may not insert it, and it can insert it in several-
921 locations. The default policy is \l InsertAtBottom but you can change-
922 this using setInsertPolicy().-
923-
924 It is possible to constrain the input to an editable combobox-
925 using QValidator; see setValidator(). By default, any input is-
926 accepted.-
927-
928 A combobox can be populated using the insert functions,-
929 insertItem() and insertItems() for example. Items can be-
930 changed with setItemText(). An item can be removed with-
931 removeItem() and all items can be removed with clear(). The text-
932 of the current item is returned by currentText(), and the text of-
933 a numbered item is returned with text(). The current item can be-
934 set with setCurrentIndex(). The number of items in the combobox is-
935 returned by count(); the maximum number of items can be set with-
936 setMaxCount(). You can allow editing using setEditable(). For-
937 editable comboboxes you can set auto-completion using-
938 setCompleter() and whether or not the user can add duplicates-
939 is set with setDuplicatesEnabled().-
940-
941 QComboBox uses the \l{Model/View Programming}{model/view-
942 framework} for its popup list and to store its items. By default-
943 a QStandardItemModel stores the items and a QListView subclass-
944 displays the popuplist. You can access the model and view directly-
945 (with model() and view()), but QComboBox also provides functions-
946 to set and get item data (e.g., setItemData() and itemText()). You-
947 can also set a new model and view (with setModel() and setView()).-
948 For the text and icon in the combobox label, the data in the model-
949 that has the Qt::DisplayRole and Qt::DecorationRole is used. Note-
950 that you cannot alter the \l{QAbstractItemView::}{SelectionMode}-
951 of the view(), e.g., by using-
952 \l{QAbstractItemView::}{setSelectionMode()}.-
