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 looses 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. This is a known issue which will be fixed in a future release. \sa QToolButton, QMenu, QAction, {Application Example} */ /*! \fn bool QToolBar::isAreaAllowed(Qt::ToolBarArea area) const Returns true if this toolbar is dockable in the given \a area; otherwise returns false. */ /*! \fn void QToolBar::addAction(QAction *action) \overload Appends the action \a action to the toolbar's list of actions. \sa QMenu::addAction(), QWidget::addAction() */ /*! \fn void QToolBar::actionTriggered(QAction *action) This signal is emitted when an action in this toolbar is triggered.
