public class CompoundBorder
extends AbstractBorder

A composite Border class used to compose two Border objects into a single border by nesting an inside Border object within the insets of an outside Border object. For example, this class may be used to add blank margin space to a component with an existing decorative border:

    Border border = comp.getBorder();
    Border margin = new EmptyBorder(10,10,10,10);
    comp.setBorder(new CompoundBorder(border, margin));
 

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 {@link java.beans.XMLEncoder}.

CompoundBorder

public CompoundBorder()

Creates a compound border with null outside and inside borders.

CompoundBorder

public CompoundBorder(Border outsideBorder,
                      Border insideBorder)

Creates a compound border with the specified outside and inside borders. Either border may be null.

Parameters:

outsideBorder - the outside border

insideBorder - the inside border to be nested

getBorderInsets

public Insets getBorderInsets(Component c)

Returns the insets of the composite border by adding the insets of the outside border to the insets of the inside border.

Overrides:

getBorderInsets in class AbstractBorder

Parameters:

c - the component for which this border insets value applies

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

getInsideBorder

public Border getInsideBorder()

Returns the inside border object.

getOutsideBorder

public Border getOutsideBorder()

Returns the outside border object.

isBorderOpaque

public boolean isBorderOpaque()

Returns whether or not this compound border is opaque. Returns true if both the inside and outside borders are non-null and opaque; returns false otherwise.

Overrides:

isBorderOpaque in class AbstractBorder

paintBorder

                        int height)

Paints the compound border by painting the outside border with the specified position and size and then painting the inside border at the specified position and size offset by the insets of the outside 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
