@JavaBean(defaultProperty="UI", description="A component which displays commonly used controls or Actions.") public class JToolBar extends JComponent implements SwingConstants, Accessible
JToolBar
provides a component that is useful for
displaying commonly used Action
s 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: Swing is not thread safe. For more information see Swing's Threading Policy.
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
has been added to the java.beans
package.
