Detailed Description#

A tool button is a special button that provides quick-access to specific commands or options. As opposed to a normal command button, a tool button usually doesn’t show a text label, but shows an icon instead.

Tool buttons are normally created when new QAction instances are created with addAction() or existing actions are added to a toolbar with addAction() . It is also possible to construct tool buttons in the same way as any other widget, and arrange them alongside other widgets in layouts.

One classic use of a tool button is to select tools; for example, the “pen” tool in a drawing program. This would be implemented by using a QToolButton as a toggle button (see setCheckable() ).

QToolButton supports auto-raising. In auto-raise mode, the button draws a 3D frame only when the mouse points at it. The feature is automatically turned on when a button is used inside a QToolBar . Change it with setAutoRaise() .

A tool button’s icon is set as QIcon . This makes it possible to specify different pixmaps for the disabled and active state. The disabled pixmap is used when the button’s functionality is not available. The active pixmap is displayed when the button is auto-raised because the mouse pointer is hovering over it.

The button’s look and dimension is adjustable with setToolButtonStyle() and setIconSize() . When used inside a QToolBar in a QMainWindow , the button automatically adjusts to QMainWindow ‘s settings (see setToolButtonStyle() and setIconSize() ). Instead of an icon, a tool button can also display an arrow symbol, specified with arrowType .

A tool button can offer additional choices in a popup menu. The popup menu can be set using setMenu() . Use setPopupMode() to configure the different modes available for tool buttons with a menu set. The default mode is DelayedPopupMode which is sometimes used with the “Back” button in a web browser. After pressing and holding the button down for a while, a menu pops up showing a list of possible pages to jump to. The timeout is style dependent, see SH_ToolButton_PopupDelay .

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

parent – PySide6.QtWidgets.QWidget

Constructs an empty tool button with parent parent.

Note

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

property PᅟySide6.QtWidgets.QToolButton.arrowType: ArrowType#

This property holds whether the button displays an arrow instead of a normal icon.

This displays an arrow as the icon for the QToolButton .

By default, this property is set to NoArrow .

Access functions:
property PᅟySide6.QtWidgets.QToolButton.autoRaise: bool#

This property holds whether auto-raising is enabled or not..

The default is disabled (i.e. false).

This property is currently ignored on macOS when using QMacStyle.

Access functions:
property PᅟySide6.QtWidgets.QToolButton.popupMode: ToolButtonPopupMode#

This property describes the way that popup menus are used with tool buttons.

By default, this property is set to DelayedPopup .

Access functions:
property PᅟySide6.QtWidgets.QToolButton.toolButtonStyle: ToolButtonStyle#

This property holds whether the tool button displays an icon only, text only, or text beside/below the icon..

The default is ToolButtonIconOnly .

To have the style of toolbuttons follow the system settings, set this property to ToolButtonFollowStyle . On Unix, the user settings from the desktop environment will be used. On other platforms, ToolButtonFollowStyle means icon only.

QToolButton automatically connects this slot to the relevant signal in the QMainWindow in which is resides.

Access functions:
PySide6.QtWidgets.QToolButton.ToolButtonPopupMode#

Describes how a menu should be popped up for tool buttons that has a menu set or contains a list of actions.

Description

QToolButton.DelayedPopup

After pressing and holding the tool button down for a certain amount of time (the timeout is style dependent, see SH_ToolButton_PopupDelay ), the menu is displayed. A typical application example is the “back” button in some web browsers’s tool bars. If the user clicks it, the browser simply browses back to the previous page. If the user presses and holds the button down for a while, the tool button shows a menu containing the current history list

QToolButton.MenuButtonPopup

In this mode the tool button displays a special arrow to indicate that a menu is present. The menu is displayed when the arrow part of the button is pressed.

QToolButton.InstantPopup

The menu is displayed, without delay, when the tool button is pressed. In this mode, the button’s own action is not triggered.
