Detailed Description

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

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 (isMovable()) between toolbar areas; see 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 does 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.

Reimplemented from QWidget.

QRect QToolBar::actionGeometry ( QAction action) const

Returns the geometry of the toolbar item associated with the given action or an invalid QRect if no matching item is found.

void QToolBar::actionTriggered ( QAction action)
signal

This signal is emitted when an action in this toolbar is triggered. This happens when the action's tool button is pressed, or when the action is triggered in some other way outside the tool bar. The parameter holds the triggered action.

QAction * QToolBar::addAction ( const QIcon icon,
const QString text 
)

Creates a new action with the given icon and text. This action is added to the end of the toolbar.

template<typename Func1 >
QAction * QToolBar::addAction ( const QIcon icon,
const QString text,
const QObject context,
Func1  slot 
)

Creates a new action with the given icon and text. This action is added to the end of the toolbar. The action's triggered() signal is connected to the slot.

If context is destroyed, the slot will not be called.

QAction * QToolBar::addAction ( const QIcon icon,
const QString text,
const QObject receiver,
const QString member 
)

Creates a new action with the given icon and text. This action is added to the end of the toolbar. The QAction::triggered() signal is connected to member in receiver.

template<typename Func1 >
QAction * QToolBar::addAction ( const QIcon icon,

Creates a new action with the given text. This action is added to the end of the toolbar. The action's triggered() signal is connected to the slot.

using

Appends action to the list of existing actions available for this widget. A QAction list is typically used to create a context QMenu, however it can be represented in different ways depending on the widget.

A QWidget should only have one of each action. Adding an action which already exists will not cause the same action to be in the widget multiple times. The ownership of action is not transferred to this QWidget.

removeAction(), insertAction(), actions(), QMenu
QAction * QToolBar::addSeparator ( )

Adds a separator to the end of the toolbar.

See also
insertSeparator()
QAction * QToolBar::addWidget ( QWidget widget)

Adds the given widget to the toolbar as the toolbar's last item.

The toolbar takes ownership of widget.

If you add a QToolButton with this method, the tools bar's Qt::ToolButtonStyle will not be respected.

Note
You should use QAction::setVisible() to change the visibility of the widget. Using QWidget::setVisible(), QWidget::show() and QWidget::hide() does not work.

void QToolBar::paintEvent ( QPaintEvent event)
overrideprotectedvirtual

This event handler can be reimplemented in a subclass to receive paint events passed in event. A paint event is a request to repaint all or part of a widget. It can happen for one of the following reasons.

  • repaint() or update() was invoked
  • widget was obscured and has now been uncovered
  • some other reason

Many widgets can simply repaint their entire surface when asked to, but some slow widgets need to optimize by painting only the requested region: QPaintEvent::region(). This speed optimization does not change the result, as painting is clipped to that region during event processing. QListView and QTableView do this, for example.

CopperSpice also tries to speed up painting by merging multiple paint events into one. When update() is called several times or the window system sends several paint events, CopperSpice merges these events into one event with a larger region (see QRegion::united()). The repaint() function does not permit this optimization, so we suggest using update() whenever possible.

When the paint event occurs, the update region has normally been erased, so you are painting on the widget's background. The background can be set using setBackgroundRole() and setPalette().

QWidget automatically double-buffers its painting, so there is no need to write double-buffering code in paintEvent() to avoid flicker.

For the X11 platform it is possible to toggle global double buffering by calling qt_x11_set_global_double_buffer().

extern void qt_x11_set_global_double_buffer(bool);
qt_x11_set_global_double_buffer(false);

Generally you should refrain from calling update() or repaint() inside a paintEvent(). For example, calling update() or repaint() on children inside a paintevent() results in undefined behavior; the child may or may not get a paint event.

Warning
If you are using a custom paint engine without the CopperSpice backingstore, Qt::WA_PaintOnScreen must be set. Otherwise, QWidget::paintEngine() will never be called; the backingstore will be used instead.
