Detailed Description¶

A QComboBox provides a means of presenting a list of options to the user in a way that takes up the minimum amount of screen space.

A combobox is a selection widget that displays the current item, and can pop up a list of selectable items. A combobox may be editable, allowing the user to modify each item in the list.

Comboboxes can contain pixmaps as well as strings; the insertItem() and setItemText() functions are suitably overloaded. For editable comboboxes, the function clearEditText() is provided, to clear the displayed string without changing the combobox’s contents.

There are three signals emitted if the current item of a combobox changes, currentIndexChanged() , currentTextChanged() and activated() . currentIndexChanged() and currentTextChanged() are always emitted regardless if the change was done programmatically or by user interaction, while activated() is only emitted when the change is caused by user interaction. The highlighted() signal is emitted when the user highlights an item in the combobox popup list. All three signals exist in two versions, one with a QString argument and one with an int argument. If the user selects or highlights a pixmap, only the int signals are emitted. Whenever the text of an editable combobox is changed the editTextChanged() signal is emitted.

When the user enters a new string in an editable combobox, the widget may or may not insert it, and it can insert it in several locations. The default policy is InsertAtBottom but you can change this using setInsertPolicy() .

It is possible to constrain the input to an editable combobox using QValidator ; see setValidator() . By default, any input is accepted.

A combobox can be populated using the insert functions, insertItem() and insertItems() for example. Items can be changed with setItemText() . An item can be removed with removeItem() and all items can be removed with clear() . The text of the current item is returned by currentText() , and the text of a numbered item is returned with text(). The current item can be set with setCurrentIndex() . The number of items in the combobox is returned by count() ; the maximum number of items can be set with setMaxCount() . You can allow editing using setEditable() . For editable comboboxes you can set auto-completion using setCompleter() and whether or not the user can add duplicates is set with setDuplicatesEnabled() .

QComboBox uses the model/view framework for its popup list and to store its items. By default a QStandardItemModel stores the items and a QListView subclass displays the popuplist. You can access the model and view directly (with model() and view() ), but QComboBox also provides functions to set and get item data (e.g., setItemData() and itemText() ). You can also set a new model and view (with setModel() and setView() ). For the text and icon in the combobox label, the data in the model that has the DisplayRole and DecorationRole is used. Note that you cannot alter the SelectionMode of the view() , e.g., by using setSelectionMode() .
