Class EtchedBorder

java.lang.Object
  javax.swing.border.AbstractBorder
      javax.swing.border.EtchedBorder

All Implemented Interfaces:

Serializable, Border

Direct Known Subclasses:

BorderUIResource.EtchedBorderUIResource

public class EtchedBorder
extends AbstractBorder

A class which implements a simple etched border which can either be etched-in or etched-out. If no highlight/shadow colors are initialized when the border is created, then these colors will be dynamically derived from the background color of the component argument passed into the paintBorder() method.

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.

                        int width,
                        int height)

Paints the border for the specified component with the specified position and size.

Specified by:

paintBorder in interface Border

Overrides:

paintBorder in class AbstractBorder

Parameters:

c - the component for which this border is being painted

g - the paint graphics

x - the x position of the painted border

y - the y position of the painted border

width - the width of the painted border

height - the height of the painted border

getBorderInsets

public Insets getBorderInsets(Component c)

Returns the insets of the border.

Specified by:

getBorderInsets in interface Border

Overrides:

getBorderInsets in class AbstractBorder

Parameters:

c - the component for which this border insets value applies

Returns:

the new Insets object initialized to 0

getBorderInsets

public Insets getBorderInsets(Component c,
                              Insets insets)

Reinitialize the insets parameter with this Border's current Insets.

Overrides:
