Class java.awt.swing.border.AbstractBorder

java.lang.Object
    |
    +----java.awt.swing.border.AbstractBorder
Subclasses:
BevelBorder, CompoundBorder, EmptyBorder, EtchedBorder, LineBorder, TitledBorder

public abstract class AbstractBorder
extends Object
implements Border, Serializable
A class which implements an empty border with no size. This provides a convenient base class from which other border classes can be easily derived.

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

                                      int x,
                                      int y,
                                      int width,
                                      int height)
This is a convience method that calls the static method.

public static Rectangle getInteriorRectangle(Component c,
                                             Border b,
                                             int x,
                                             int y,
                                             int width,
                                             int height)
