Detailed Description

The QToolBar class provides a movable panel that contains a set of controls.

\inmodule QtWidgets

A toolbar is typically created by calling \l QMainWindow::addToolBar(const QString &title), but it can also be added as the first widget in a QVBoxLayout, for example.

Toolbar buttons are added by adding actions, using addAction() or insertAction(). Groups of buttons can be separated using addSeparator() or insertSeparator(). If a toolbar button is not appropriate, a widget can be inserted instead using addWidget() or insertWidget(). Examples of suitable widgets are QSpinBox, QDoubleSpinBox, and QComboBox. When a toolbar button is pressed, it emits the actionTriggered() signal.

A toolbar can be fixed in place in a particular area (e.g., at the top of the window), or it can be movable between toolbar areas; see setMovable(), isMovable(), allowedAreas() and isAreaAllowed().

When a toolbar is resized in such a way that it is too small to show all the items it contains, an extension button will appear as the last item in the toolbar. Pressing the extension button will pop up a menu containing the items that do not currently fit in the toolbar.

When a QToolBar is not a child of a QMainWindow, it loses the ability to populate the extension pop up with widgets added to the toolbar using addWidget(). Please use widget actions created by inheriting QWidgetAction and implementing QWidgetAction::createWidget() instead.

◆ addAction() [7/7]

void QWidget::addAction ( QAction * action )

Appends the action action to this widget's list of actions.

All QWidgets have a list of \l{QAction}s. However, they can be represented graphically in many different ways. The default use of the QAction list (as returned by actions()) is to create a context QMenu.

A QWidget should only have one of each action and adding an action it already has will not cause the same action to be in the widget twice.

The ownership of action is not transferred to this QWidget.

Property Documentation

◆ allowedAreas

QToolBar::allowedAreas

readwrite

areas where the toolbar may be placed

The default is Qt::AllToolBarAreas.

This property only makes sense if the toolbar is in a QMainWindow.

See also: movable

Definition at line 27 of file qtoolbar.h.

◆ floatable

QToolBar::floatable

readwrite

whether the toolbar can be dragged and dropped as an independent window.

The default is true.

Definition at line 35 of file qtoolbar.h.

Referenced by setFloatable().

◆ floating

QToolBar::floating

read

whether the toolbar is an independent window.

By default, this property is true.

See also: QWidget::isWindow()

Definition at line 34 of file qtoolbar.h.

◆ iconSize

QToolBar::iconSize

readwrite

size of icons in the toolbar.

The default size is determined by the application's style and is derived from the QStyle::PM_ToolBarIconSize pixel metric. It is the maximum size an icon can have. Icons of smaller size will not be scaled up.

Definition at line 31 of file qtoolbar.h.

Referenced by setIconSize().

◆ movable

QToolBar::movable

readwrite

whether the user can move the toolbar within the toolbar area, or between toolbar areas.

By default, this property is true.

This property only makes sense if the toolbar is in a QMainWindow.

See also: allowedAreas

Definition at line 26 of file qtoolbar.h.

Referenced by setMovable().

◆ orientation

QToolBar::orientation

readwrite

orientation of the toolbar

The default is Qt::Horizontal.

This function should not be used when the toolbar is managed by QMainWindow. You can use QMainWindow::addToolBar() or QMainWindow::insertToolBar() if you wish to move a toolbar that is already added to a main window to another Qt::ToolBarArea.

Definition at line 29 of file qtoolbar.h.

Referenced by initStyleOption(), and setOrientation().

◆ toolButtonStyle

QToolBar::toolButtonStyle

readwrite

the style of toolbar buttons

This property defines the style of all tool buttons that are added as \l{QAction}s. Note that if you add a QToolButton with the addWidget() method, it will not get this button style.

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

The default is Qt::ToolButtonIconOnly.
