    \class QToolBar

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

    \ingroup application
    \mainclass

    Toolbar buttons are added by adding \e 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 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.
