Field Detail

color

protected java.awt.Color color

A non-null Color, giving the color of the bortder.

width

protected int width

A non-negative integer giving the width of the border in pixels.

Constructor Detail

DrawBorder

public DrawBorder()

Create a black border that is one pixel thick.

DrawBorder

public DrawBorder(java.awt.Color color,
                  int width)

Create a border with the spcified color and width. If the color is null, black is used. If the width is less than zero, a width of 1 is used. A border of width zero is invisible.

Parameters:

color - border color

width - border width

Method Detail

getColor

public java.awt.Color getColor()

Get the color of the border.

Returns:

border color

setColor

public void setColor(java.awt.Color c)

Set the color of the border to the specified color. If the color is null, nothing is done.

Parameters:

c - border color

getWidth

public int getWidth()

Get the width of the border, in pixels.

Overrides:

getWidth in class java.awt.Component

Returns:

border width

setWidth

public void setWidth(int w)

Set the width of the border to be w pixels. If w is negative, this is ignored. A border of witdth 0 is invisible.

Parameters:

w - the desired width for the border.

draw

public void draw(java.awt.Graphics g,
                 boolean changed)

Draw the border in the given graphics context. This is not ordinarily called directly.

Specified by:

draw in class Drawable

Parameters:

g - graphics context

changed - true or false
