 /**
  * @short Floatable toolbar with auto resize.
  *
  * A KDE-style toolbar.
  *
  * KToolBar can be dragged around in and between different docks.
  *
  * A KToolBar can contain all sorts of widgets.
  *
  * KToolBar can be used as a standalone widget, but KMainWindow
  * provides easy factories and management of one or more toolbars.
  * Once you have a KToolBar object, you can insert items into it with the
  * insert... methods, or remove them with the removeItem() method. This
  * can be done at any time; the toolbar will be automatically updated.
  * There are also many methods to set per-child properties like alignment
  * and toggle behavior.
  *
  * KToolBar uses a global config group to load toolbar settings on
  * construction. It will reread this config group on a
  * KApplication::appearanceChanged() signal.
