public class JToolBar
extends JComponent
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.
A tool bar can be dragged out into a separate window by the user (unless the floatable property is set to false). In order 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'.
For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JToolBar key assignments.
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. A future release of Swing will provide support for long term persistence.
