public class JToolBar

implements SwingConstants   , Accessible   

JToolBar provides a component that is useful for displaying commonly used Actions or controls. For examples and information on using tool bars see How to Use Tool Bars, a section in The Java Tutorial.

With most look and feels, the user can drag out a tool bar into a separate window (unless the floatable property is set to false). For drag-out to work correctly, it is recommended that you add JToolBar instances to one of the four "sides" of a container whose layout manager is a BorderLayout, and do not add children to any of the other four "sides".

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder .
