Introduction

This composite displays a brushed metal texture "à la mac". It is based on the article Creating a Brushed Metal Texture (http://www.jhlabs.com/ip/brushed_metal.html) by Jerry Huxtable.

Usage

You can use this control like a SWT composite :

// Displays the composite
final BrushedMetalComposite bmc = new BrushedMetalComposite(shell, SWT.NONE);

// And the content
final RowLayout layout2 = new RowLayout(SWT.VERTICAL);
layout2.marginWidth = layout2.marginHeight = layout2.spacing = 10;
bmc.setLayout(layout2);
for (int i = 0; i < 8; i++) {
    final Button button = new Button(bmc, SWT.RADIO);
    button.setText("Button " + i);
}

Parameters

You can play with 5 parameters :

Radius - the "radius" of the blur.
Amount - the amount of noise to add (range 0-1)
Color - the color of the metal
Shine - the amount of shine to add (range 0-1)
Monochrome - true if the noise should be monochrome

For a better understanding of the influence of these parameters, you can play with the application"BrushedMetalCompositePlayer" (file src/test/java/org/mihalis/opal/brushedMetalComposite/BrushedMetalCompositePlayer.java).
