\class QToolBar
\brief The QToolBar class provides a movable panel that contains a
set of controls.
\ingroup mainwindow-classes
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.
