Detailed Description

The QAction class stores information about a process or command which can be added to a menu or a toolbar. A QAction can have an icon, menu text, icon text, a shortcut, status text, "What's This?" text, and a tooltip. Most of these properties can be passed in the constructor. They can also be set by calling methods like setIcon(), setText(), setIconText(), setShortcut(), setStatusTip(), setWhatsThis(), and setToolTip().

Calling QAction::setFont() can be used to change the font for a specific action.

Menus and ToolBars

An action is added to a widget by calling methods like QMenu::addAction() or QGraphicsWidget::addAction().

Once a QAction has been created it can be added to any menu or toolbar. The action must be connected to the slot which will perform the required action. Actions should be created as children of the window they are used in. In most cases actions will be children of the application's main window.

If the same QAction is added to the menu and the toolbar and the action is checkable, then changing the status from menu will also change the status on the toolbar.

Example

QAction *openFile = new QAction(QIcon(":/images/open.png"), tr("&Open..."), this);
 
openFile->setShortcuts(QKeySequence::Open);
openFile->setStatusTip(tr("Open an existing file"));
 
connect(openFile, &QAction::triggered, this, &MyMainWIndow::open);
 
QMenu *fileMenu = menuBar()->addMenu(tr("File"));
fileMenu->addAction(openFile);
 
QToolBar *fileToolBar = addToolBar(tr("File"));
fileToolBar->addAction(openFile);

Member Enumeration Documentation

enum QAction::ActionEvent

This enum type is used when calling QAction::activate()

Constant	Value	Description
`QAction::Trigger`	`0`	Emits the QAction::triggered() signal
`QAction::Hover`	`1`	Emits the QAction::hovered() signal

enum QAction::MenuRole

This enum describes how an action should be moved into the application menu on Mac OS X.

Setting this value only has effect on items that are in the immediate menus of the menubar, not the submenus of those menus. For example, if you have File menu in your menubar and the File menu has a submenu, setting the MenuRole for the actions in that submenu have no effect. They will never be moved.

Constant	Value	Description
`QAction::NoRole`	`0`	This action should not be put into the application menu
`QAction::TextHeuristicRole`	`1`	Action should be put in the application menu based on the action's text as described in the QMenuBar documentation.
`QAction::ApplicationSpecificRole`	`2`	Action should be put in the application menu with an application specific role
`QAction::AboutCsRole`	`3`	Action matches handles the "About CopperSpice" menu item.
`QAction::AboutRole`	`4`	Action should be placed where the "About" menu item is in the application menu. The text of the menu item will be set to "About YourAppName". The Application name is obtained from the Info.plist file located in the application bundle.
`QAction::PreferencesRole`	`5`	Action should be placed where the "Preferences..." menu item is in the application menu.
`QAction::QuitRole`	`6`	Action should be placed where the Quit menu item is in the application menu.

enum QAction::Priority

This enum defines priorities for actions in user interface.

Constant	Value	Description
`QAction::LowPriority`	`0`	The action should not be prioritized in the user interface.
`QAction::NormalPriority`	`128`
`QAction::HighPriority`	`256`	The action should be prioritized in the user interface.

Constructor & Destructor Documentation

QAction::QAction ( QObject * parent )

explicit

Constructs an action with parent. If the parent is an action group the action will be automatically inserted into the group.

QAction::QAction	(	const QString &	text,
		QObject *	parent
	)

Constructs an action with some text and parent. If parent is an action group the action will be automatically inserted into the group.

The action uses a stripped version of text. For example, "&Menu Option..." becomes "Menu Option" as descriptive text for tool buttons. You can override this by setting a specific description with setText(). The same text will be used for tooltips unless you specify a different text using setToolTip().

QAction::QAction	(	const QIcon &	icon,
		const QString &	text,
		QObject *	parent
	)

Constructs an action with an icon and some text and parent. If parent is an action group the action will be automatically inserted into the group.

The action uses a stripped version of text. For example, "&Menu Option..." becomes "Menu Option" as descriptive text for tool buttons. You can override this by setting a specific description with setText(). The same text will be used for tooltips unless you specify a different text using setToolTip().

QAction::~QAction ( )

Property Documentation

QAction::autoRepeat

This property holds whether the action can auto repeat. If true the action will auto repeat when the keyboard shortcut combination is held down, provided that keyboard auto repeat is enabled on the system.

The default value is true.

Properties	Class Methods
read	autoRepeat
write	setAutoRepeat
notify	changed

QAction::checkable

This property holds whether the action is a checkable action.

A checkable action is one which has an on/off state. For example, in a word processor, a Bold toolbar button may be either on or off. An action which is not a toggle action is a command action. A command action is simply executed, e.g. file save. In some situations, the state of one toggle action should depend on the state of others. For example, "Left Align", "Center" and "Right Align" toggle actions are mutually exclusive. To achieve exclusive toggling, add the relevant toggle actions to a QActionGroup with the QActionGroup::exclusive property set to true.

By default, this property is false.

See also: QAction::setChecked()

Properties	Class Methods
read	isCheckable
write	setCheckable
notify	changed

QAction::checked

This property holds whether the action is checked. Only checkable actions can be checked. By default, this is false and the action is unchecked.

See also: checkable

Properties	Class Methods
read	isChecked
write	setChecked

QAction::enabled

This property holds whether the action is enabled.

Disabled actions can not be chosen by the user. They do not disappear from menus or toolbars, but they are displayed in a way which indicates that they are unavailable. For example, they might be displayed using only shades of gray. What's This? help on disabled actions is still available, provided that the QAction::whatsThis property is set. An action will be disabled when all widgets to which it is added (with QWidget::addAction()) are disabled or not visible. When an action is disabled, it is not possible to trigger it through its shortcut.

By default, this property is true and the action is enabled.

See also: text

Properties	Class Methods
read	isEnabled
write	setEnabled

QAction::font

This property holds the action's font. The font property is used to render the text set on the QAction. The font will can be considered a hint as it will not be consulted in all cases based upon application and style.

By default, this property contains the application's default font.

See also: QAction::setText(), QStyle

Properties	Class Methods
read	font
write	setFont
notify	changed

QAction::icon

This property holds the action's icon. In toolbars the icon is used as the tool button icon. In menus it is displayed to the left of the menu text. If a null icon is passed to this method the icon for the action is cleared.

There is no default icon.

Properties	Class Methods
read	icon
write	setIcon
notify	changed

QAction::iconText

This property holds the action's descriptive icon text.

If QToolBar::toolButtonStyle is set to a value that permits text to be displayed, the text defined held in this property appears as a label in the relevant tool button. It also serves as the default text in menus and tooltips if the action has not been defined with setText() or setToolTip(), and will also be used in toolbar buttons if no icon has been defined using setIcon(). If the icon text is not explicitly set, the action's normal text will be used for the icon text.

By default, this property contains an empty string.

See also: setToolTip(), setStatusTip()

Properties	Class Methods
read	iconText
write	setIconText
notify	changed

QAction::iconVisibleInMenu

This property holds whether or not an action should show an icon in a menu.

In some applications, it may make sense to have actions with icons in the toolbar, but not in menus. If true, the icon (if valid) is shown in the menu, when it is false, it is not shown. The default is to follow whether the Qt::AA_DontShowIconsInMenus attribute is set for the application. Explicitly settings this property overrides the presence (or absence) of the attribute.

QApplication app(argc, argv);
app.setAttribute(Qt::AA_DontShowIconsInMenus);   // Icons are *no longer shown* in menus
 
QAction *myAction = new QAction();
 
myAction->setIcon(SomeIcon);
myAction->setIconVisibleInMenu(true);            // Icon *will* be shown in menus for *this* action.

QAction::menuRole

This property holds the action's menu role.

This indicates what role the action serves in the application menu on Mac OS X. By default all action have the TextHeuristicRole, which means that the action is added based on its text . The menu role can only be changed before the actions are put into the menu bar in Mac OS X (usually just before the first application window is shown).

See also: QMenuBar

Properties	Class Methods
read	menuRole
write	setMenuRole
notify	changed

QAction::priority

This property holds the action's priority in the user interface. This property can be set to indicate how the action should be prioritized in the user interface. For instance, when toolbars have the Qt::ToolButtonTextBesideIcon mode set, then actions with LowPriority will not show the text labels.

Properties	Class Methods
read	priority
write	setPriority

QAction::shortcut

This property holds the action's primary shortcut key. Valid keycodes for this property can be found in Qt::Key and Qt::Modifier. There is no default shortcut key.

Properties	Class Methods

This property holds the action's status tip. The status tip is displayed on all status bars provided by the action's top level parent widget.

By default, this property contains an empty string.

See also: setToolTip(), showStatusText()

Properties	Class Methods
read	statusTip
write	setStatusTip
notify	changed

QAction::text

This property holds the action's descriptive text. If the action is added to a menu, the menu option will consist of the icon (if there is one), the text, and the shortcut (if there is one). If the text is not explicitly set in the constructor, or by using setText(), the action's description icon text will be used as text.

There is no default text.
