842 \class QComboBox -
843 \brief The QComboBox widget is a combined button and popup list. -
844 -
845 \ingroup basicwidgets -
846 \inmodule QtWidgets -
847 -
848 A QComboBox provides a means of presenting a list of options to the user -
849 in a way that takes up the minimum amount of screen space. -
850 -
851 A combobox is a selection widget that displays the current item, -
852 and can pop up a list of selectable items. A combobox may be editable, -
853 allowing the user to modify each item in the list. -
854 -
855 Comboboxes can contain pixmaps as well as strings; the -
856 insertItem() and setItemText() functions are suitably overloaded. -
857 For editable comboboxes, the function clearEditText() is provided, -
858 to clear the displayed string without changing the combobox's -
859 contents. -
860 -
861 There are two signals emitted if the current item of a combobox -
862 changes, currentIndexChanged() and activated(). -
863 currentIndexChanged() is always emitted regardless if the change -
864 was done programmatically or by user interaction, while -
865 activated() is only emitted when the change is caused by user -
866 interaction. The highlighted() signal is emitted when the user -
867 highlights an item in the combobox popup list. All three signals -
868 exist in two versions, one with a QString argument and one with an -
869 \c int argument. If the user selects or highlights a pixmap, only -
870 the \c int signals are emitted. Whenever the text of an editable -
871 combobox is changed the editTextChanged() signal is emitted. -
872 -
873 When the user enters a new string in an editable combobox, the -
874 widget may or may not insert it, and it can insert it in several -
875 locations. The default policy is \l InsertAtBottom but you can change -
876 this using setInsertPolicy(). -
877 -
878 It is possible to constrain the input to an editable combobox -
879 using QValidator; see setValidator(). By default, any input is -
880 accepted. -
881 -
882 A combobox can be populated using the insert functions, -
883 insertItem() and insertItems() for example. Items can be -
884 changed with setItemText(). An item can be removed with -
885 removeItem() and all items can be removed with clear(). The text -
886 of the current item is returned by currentText(), and the text of -
887 a numbered item is returned with text(). The current item can be -
888 set with setCurrentIndex(). The number of items in the combobox is -
889 returned by count(); the maximum number of items can be set with -
890 setMaxCount(). You can allow editing using setEditable(). For -
891 editable comboboxes you can set auto-completion using -
892 setCompleter() and whether or not the user can add duplicates -
893 is set with setDuplicatesEnabled(). -
894 -
895 QComboBox uses the \l{Model/View Programming}{model/view -
896 framework} for its popup list and to store its items. By default -
897 a QStandardItemModel stores the items and a QListView subclass -
898 displays the popuplist. You can access the model and view directly -
899 (with model() and view()), but QComboBox also provides functions -
900 to set and get item data (e.g., setItemData() and itemText()). You -
901 can also set a new model and view (with setModel() and setView()). -
902 For the text and icon in the combobox label, the data in the model -
903 that has the Qt::DisplayRole and Qt::DecorationRole is used. Note -
904 that you cannot alter the \l{QAbstractItemView::}{SelectionMode} -
905 of the view(), e.g., by using -
906 \l{QAbstractItemView::}{setSelectionMode()}. -
