Class MatrixBorder

java.lang.Object
  javax.swing.border.AbstractBorder
      com.jstatcom.component.MatrixBorder

All Implemented Interfaces:

java.io.Serializable, javax.swing.border.Border

public final class MatrixBorder
extends javax.swing.border.AbstractBorder

This border puts angular brackets [ ] around a component. It can be used to visualize a matrix or a range object. The appearance of the brackets can be configured via the constructor, but reasonable defaults are provided by static factory methods as well.

Constructor Summary

MatrixBorder()
Creates the default MatrixBorder instance.

MatrixBorder(int thick, int width, int outerTop, int innerTop, int outerLeft, int innerLeft)
Creates a MatrixBorder instance according to spacing and size parameters.

Method Summary

java.awt.Insets	getBorderInsets(java.awt.Component c) Overrides super method.
java.awt.Insets	getBorderInsets(java.awt.Component c, java.awt.Insets insets) Reinitialize the insets parameter with this border's current insets.
static MatrixBorder	getInstanceSmall() Gets a MatrixBorder that is smaller than the default, for example to be used with default sized text fields.
static MatrixBorder	getInstanceThick() Gets a MatrixBorder that is thicker than the default.
boolean	isBorderOpaque() This default implementation returns false.
void	paintBorder(java.awt.Component c, java.awt.Graphics g, int x, int y, int width, int height) Called by the repaint manager to paint this border.

Constructor Detail

MatrixBorder

public MatrixBorder()

Creates the default MatrixBorder instance.

MatrixBorder

public MatrixBorder(int thick,
                    int width,
                    int outerTop,
                    int innerTop,
                    int outerLeft,
                    int innerLeft)

Creates a MatrixBorder instance according to spacing and size parameters. Instead of this constructor, the static factory methods can be called for some reasonable variations of the default MatrixBorder.

Parameters:

thick - border thickness, default is 1

width - width of the brackets, default is 8

outerTop - space between outer top and bracket, default is 1

innerTop - space between bracket and top of component, default is 3

outerLeft - space between outer left and bracket, default is 1

innerLeft - space between bracket and left of component, default is 3

Method Detail

getBorderInsets

public java.awt.Insets getBorderInsets(java.awt.Component c)

Overrides super method.

Specified by:

getBorderInsets in interface javax.swing.border.Border

Overrides:

getBorderInsets in class javax.swing.border.AbstractBorder

Parameters:

c - the component for which this border insets value applies

Returns:

the insets

getBorderInsets

public java.awt.Insets getBorderInsets(java.awt.Component c,
                                       java.awt.Insets insets)

Reinitialize the insets parameter with this border's current insets. Overrides super method.

Overrides:

getBorderInsets in class javax.swing.border.AbstractBorder

Parameters:

c - the component for which this border insets value applies

insets - the object to be reinitialized

Returns:

the insets

getInstanceSmall

public static MatrixBorder getInstanceSmall()

Gets a MatrixBorder that is smaller than the default, for example to be used with default sized text fields.

Returns:

a new border instance

getInstanceThick

public static MatrixBorder getInstanceThick()

Gets a MatrixBorder that is thicker than the default.

Returns:

a new border instance

isBorderOpaque

public boolean isBorderOpaque()

This default implementation returns false. Overrides super method.

Specified by:

                        int width,
                        int height)

Called by the repaint manager to paint this border.

Specified by:

paintBorder in interface javax.swing.border.Border

Overrides:

paintBorder in class javax.swing.border.AbstractBorder
