Detailed Description#

Collapsed QCombobox

Expanded QCombobox

Display Features#

A QComboBox is a compact way to present a list of options to the user.

A combobox is a selection widget that shows the current item, and pops up a list of selectable items when clicked. Comboboxes can contain pixmaps as well as strings if the insertItem() and setItemText() functions are suitably overloaded.

Editing Features#

A combobox may be editable, allowing the user to modify each item in the list. For editable comboboxes, the function clearEditText() is provided, to clear the displayed string without changing the combobox’s contents.

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() .

Signals#

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.

Model/View Framework#

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, for example, 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 Qt::DisplayRole and Qt::DecorationRole is used.

Note

You cannot alter the SelectionMode of the view() , for example, by using setSelectionMode() .

class PySide6.QtWidgets.QComboBox([parent=None])#
Parameters:

parent – PySide6.QtWidgets.QWidget

Constructs a combobox with the given parent, using the default model QStandardItemModel.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.QtWidgets.QComboBox.count: int#

This property holds the number of items in the combobox..

By default, for an empty combo box, this property has a value of 0.

Access functions:
property PᅟySide6.QtWidgets.QComboBox.currentData: object#

This property holds the data for the current item.

By default, for an empty combo box or a combo box in which no current item is set, this property contains an invalid QVariant.

Access functions:
property PᅟySide6.QtWidgets.QComboBox.currentIndex: int#

This property holds the index of the current item in the combobox..

The current index can change when inserting or removing items.

By default, for an empty combo box or a combo box in which no current item is set, this property has a value of -1.

Access functions:
property PᅟySide6.QtWidgets.QComboBox.currentText: str#

This property holds the current text.

If the combo box is editable, the current text is the value displayed by the line edit. Otherwise, it is the value of the current item or an empty string if the combo box is empty or no current item is set.

The setter setCurrentText() simply calls setEditText() if the combo box is editable. Otherwise, if there is a matching text in the list, currentIndex is set to the corresponding index.

editable setEditText()

Access functions:
property PᅟySide6.QtWidgets.QComboBox.duplicatesEnabled: bool#

This property holds whether the user can enter duplicate items into the combobox..

Note that it is always possible to programmatically insert duplicate items into the combobox.

By default, this property is false (duplicates are not allowed).

Access functions:
property PᅟySide6.QtWidgets.QComboBox.editable: bool#

This property holds whether the combo box can be edited by the user..

By default, this property is false. The effect of editing depends on the insert policy.

Note

When disabling the editable state, the validator and completer are removed.

See also

InsertPolicy

Access functions:
property PᅟySide6.QtWidgets.QComboBox.frame: bool#

This property holds whether the combo box draws itself with a frame..

If enabled (the default) the combo box draws itself inside a frame, otherwise the combo box draws itself without any frame.

Access functions:
property PᅟySide6.QtWidgets.QComboBox.iconSize: PySide6.QtCore.QSize#

This property holds the size of the icons shown in the combobox..

Unless explicitly set this returns the default value of the current style. This size is the maximum size that icons can have; icons of smaller size are not scaled up.

Access functions:
property PᅟySide6.QtWidgets.QComboBox.insertPolicy: InsertPolicy#

This property holds the policy used to determine where user-inserted items should appear in the combobox..

The default value is InsertAtBottom , indicating that new items will appear at the bottom of the list of items.

See also

InsertPolicy

Access functions:
property PᅟySide6.QtWidgets.QComboBox.maxCount: int#

This property holds the maximum number of items allowed in the combobox..

Note

If you set the maximum number to be less then the current amount of items in the combobox, the extra items will be truncated. This also applies if you have set an external model on the combobox.

By default, this property’s value is derived from the highest signed integer available (typically 2147483647).

Access functions:
property PᅟySide6.QtWidgets.QComboBox.maxVisibleItems: int#

This property holds the maximum allowed size on screen of the combo box, measured in items.

By default, this property has a value of 10.

Note

This property is ignored for non-editable comboboxes in styles that returns true for SH_ComboBox_Popup such as the Mac style or the Gtk+ Style.

Access functions:
property PᅟySide6.QtWidgets.QComboBox.minimumContentsLength: int#

This property holds the minimum number of characters that should fit into the combobox..

The default value is 0.

If this property is set to a positive value, the minimumSizeHint() and sizeHint() take it into account.

See also

sizeAdjustPolicy

Access functions:
property PᅟySide6.QtWidgets.QComboBox.modelColumn: int#

This property holds the column in the model that is visible..

If set prior to populating the combo box, the pop-up view will not be affected and will show the first column (using this property’s default value).

By default, this property has a value of 0.

Note

In an editable combobox, the visible column will also become the completion column .

Access functions:
property PᅟySide6.QtWidgets.QComboBox.placeholderText: str#

This property holds Sets a placeholderText text shown when no valid index is set..

The placeholderText will be shown when an invalid index is set. The text is not accessible in the dropdown list. When this function is called before items are added the placeholder text will be shown, otherwise you have to call setCurrentIndex (-1) programmatically if you want to show the placeholder text. Set an empty placeholder text to reset the setting.

When the QComboBox is editable, use setPlaceholderText() instead.

Access functions:
property PᅟySide6.QtWidgets.QComboBox.sizeAdjustPolicy: SizeAdjustPolicy#

This property holds the policy describing how the size of the combobox changes when the content changes..

The default value is AdjustToContentsOnFirstShow .
