Class LineBorder

java.lang.Object

javax.swing.border.AbstractBorder

javax.swing.border.LineBorder

All Implemented Interfaces:

Serializable, Border

Direct Known Subclasses:

BorderUIResource.LineBorderUIResource

public class LineBorder
extends AbstractBorder

A class which implements a line border of arbitrary thickness and of a single color.

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. Please see XMLEncoder.
