Detailed Description

The QToolButton class provides a quick-access button to commands or options, usually used inside a QToolBar. 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 does not show a text label, but shows an icon instead. Tool buttons are normally created when new QAction instances are created with QToolBar::addAction() or existing actions are added to a toolbar with QToolBar::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 setToggleButton()). 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 QMainWindow::setToolButtonStyle() and QMainWindow::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. The default delay is 600 ms, which can be adjusted with setPopupDelay().

Member Enumeration Documentation

enum QToolButton::ToolButtonPopupMode

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

Constant	Value	Description
`QToolButton::DelayedPopup`	`0`	After pressing the mouse button for a certain amount of time a menu is displayed
`QToolButton::MenuButtonPopup`	`1`	Displays an arrow to indicate that a menu is present, the menu is displayed when the arrow is pressed.
`QToolButton::InstantPopup`	`2`	The menu is displayed immediately when the tool button is pressed, the button's action is not triggered.

Constructor & Destructor Documentation

QToolButton::QToolButton ( QWidget * parent = nullptr )

explicit

Constructs an empty tool button with the given parent.

QToolButton::~QToolButton ( )

Destroys the object and frees any allocated resources.

Method Documentation

void QToolButton::actionEvent ( QActionEvent * event )

overrideprotectedvirtual

Reimplemented from QWidget::actionEvent()

Qt::ArrowType QToolButton::arrowType ( ) const

Returns the value of the property.

bool QToolButton::autoRaise ( ) const

Returns the value of the property.

void QToolButton::changeEvent ( QEvent * event )

overrideprotectedvirtual

Reimplemented from QAbstractButton::changeEvent()

QAction * QToolButton::defaultAction ( ) const

Returns the default action.

See also: setDefaultAction()

void QToolButton::enterEvent ( QEvent * event )

bool QToolButton::hitButton ( const QPoint & pos ) const

overrideprotectedvirtual

Reimplemented from QAbstractButton::hitButton()

void QToolButton::initStyleOption ( QStyleOptionToolButton * option ) const

protected

Initialize option with the values from this QToolButton. This method is useful for subclasses when they need a QStyleOptionToolButton, but do not want to fill in all the information themselves.

See also: QStyleOption::initFrom()

void QToolButton::leaveEvent ( QEvent * event )

overrideprotectedvirtual

Reimplemented from QWidget::leaveEvent()

QMenu * QToolButton::menu ( ) const

Returns the associated menu or a nullptr if no menu has been defined.

Reimplemented from QAbstractButton::mouseReleaseEvent()

void QToolButton::nextCheckState ( )

overrideprotectedvirtual

Reimplemented from QAbstractButton::nextCheckState()

void QToolButton::paintEvent ( QPaintEvent * event )

overrideprotectedvirtual

Paints the button in response to the paint event.

Implements QAbstractButton::paintEvent()

ToolButtonPopupMode QToolButton::popupMode ( ) const

Returns the value of the property.

void QToolButton::setArrowType ( Qt::ArrowType type )

Sets the value of the property to type.

void QToolButton::setAutoRaise ( bool enable )

Sets the value of the property to enable.

void QToolButton::setDefaultAction ( QAction * action )

slot

Sets the default action to action.

If a tool button has a default action, the action defines the button's properties like text, icon, tool tip, etc.

See also: defaultAction()

void QToolButton::setMenu ( QMenu * menu )

Associates the given menu with this tool button. The menu will be shown according to the button's popupMode. Ownership of the menu is not transferred to the tool button.

See also: menu()

void QToolButton::setPopupMode ( ToolButtonPopupMode mode )

Sets the value of the property to mode.

void QToolButton::setToolButtonStyle ( Qt::ToolButtonStyle style )

slot

Sets the value of the property to style.

void QToolButton::showMenu ( )

slot

Displays the associated popup menu. If there is no such menu, this function does nothing. This function does not return until the popup menu has been closed by the user.

QSize QToolButton::sizeHint ( ) const

overridevirtual

Reimplemented from QWidget::sizeHint()

void QToolButton::timerEvent ( QTimerEvent * event )

overrideprotected

Reimplemented from QAbstractButton::timerEvent()

Qt::ToolButtonStyle QToolButton::toolButtonStyle ( ) const

Returns the value of the property.

void QToolButton::triggered ( QAction * action )

signal

This signal is emitted when the given action is triggered.

The action may also be associated with other parts of the user interface, such as menu items and keyboard shortcuts. Sharing actions in this way helps make the user interface more consistent and is often less work to implement.

Property Documentation

QToolButton::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 Qt::NoArrow.

Properties	Class Methods
read	arrowType
write	setArrowType

QToolButton::autoRaise

This property holds whether auto-raising is enabled or not. The default is disabled (i.e. false).

This property is currently ignored on Mac OS X when using QMacStyle.

Properties	Class Methods
read	autoRaise
write	setAutoRaise

QToolButton::popupMode

This property describes the way that popup menus are used with tool buttons. By default, this property is set to DelayedPopup.

Properties	Class Methods
read	popupMode
write	setPopupMode

QToolButton::toolButtonStyle

This property holds whether the tool button displays an icon only, text only, or text beside/below the icon. The default is Qt::ToolButtonIconOnly.

To have the style of toolbuttons follow the system settings (as available in GNOME and KDE desktop environments), set this property to Qt::ToolButtonFollowStyle. QToolButton automatically connects this slot to the relevant signal in the QMainWindow in which is resides.
