Class EtchedBorder

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

All Implemented Interfaces:

Border, Serializable

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.

Method Detail

paintBorder

public void paintBorder(Component c,
                        Graphics g,
                        int x,
                        int y,
                        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:

getBorderInsets in class AbstractBorder

Parameters:

c - the component for which this border insets value applies

insets - the object to be reinitialized

Returns:

the insets object

isBorderOpaque

public boolean isBorderOpaque()

Returns whether or not the border is opaque.

Specified by:

isBorderOpaque in interface Border

Overrides:

isBorderOpaque in class AbstractBorder

Returns:

false

getEtchType

public int getEtchType()

Returns which etch-type is set on the etched border.

getHighlightColor

public Color getHighlightColor(Component c)

Returns the highlight color of the etched border when rendered on the specified component. If no highlight color was specified at instantiation, the highlight color is derived from the specified component's background color.

Parameters:

c - the component for which the highlight may be derived

getHighlightColor

public Color getHighlightColor()

Returns the highlight color of the etched border. Will return null if no highlight color was specified at instantiation.

getShadowColor

public Color getShadowColor(Component c)

Returns the shadow color of the etched border when rendered on the specified component. If no shadow color was specified at instantiation, the shadow color is derived from the specified component's background color.

Parameters:

c - the component for which the shadow may be derived

getShadowColor

public Color getShadowColor()

Returns the shadow color of the etched border. Will return null if no shadow color was specified at instantiation.
