The typical toolbar is a collection of butcons (icons that serve as buttons), usually without text labels, in a horizontal slab positioned directly below the menu bar or in a vertical slab attached to the side of the main window (see Figure 23-1).

• 典型的工具栏是图标按钮（也就是具有按钮功能的图标）的集合，通常没有文本标签。 它以水平板的方式置于菜单栏的下方，或者以垂直板的形式紧贴在主窗口的一边（参见图23-1）。
