public abstract class AbstractBorder
extends Object
implements Border, Serializable

A class that 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 applications running the same version of Swing. A future release of Swing will provide support for long term persistence.

                        int height)
This default implementation does no painting.
Specified by:
paintBorder in interface Border
Following copied from interface: javax.swing.border.Border
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)
This default implementation returns the value of getBorderMargins.
Specified by:
getBorderInsets in interface Border
Following copied from interface: javax.swing.border.Border
Parameters:
c - the component for which this border insets value applies

getBorderInsets

public Insets getBorderInsets(Component c,
                              Insets insets)
Reinitializes the insets parameter with this Border's current Insets.
Parameters:
c - the component for which this border insets value applies
insets - the object to be reinitialized

isBorderOpaque

public boolean isBorderOpaque()
This default implementation returns false.
Specified by:
isBorderOpaque in interface Border

getInteriorRectangle

public Rectangle getInteriorRectangle(Component c,
                                      int x,
                                      int y,
                                      int width,
                                      int height)
This convenience method calls the static method.

getInteriorRectangle

public static Rectangle getInteriorRectangle(Component c,
                                             Border b,
                                             int x,
                                             int y,
                                             int width,
                                             int height)
Returns a rectangle using the arguments minus the insets of the border. This is useful for determining the area that components should draw in that will not intersect the border.
