public class WindowStyle {

public WindowStyle() {
final Display display = Display.getDefault();
final Shell shell = new Shell(SWT.MIN);
shell.setText("ExpandBar练习");
shell.setSize(200, 518);

new Label(comp1,SWT.NONE).setImage(new Image(display,"icons/main.gif"));
new Link(comp1,SWT.NONE).setText("<a>更改一个设置</a>");
ExpandItem item1 = new ExpandItem(expandBar, SWT.NONE);
item1.setText("系统任务");
item1.setHeight(75);// 设置Item的高度
item1.setControl(comp1);// setControl方法控制comp1的显现
}

{
Composite comp2 = new Composite(expandBar,SWT.NONE);

ExpandItem item1 = new ExpandItem(expandBar, SWT.NONE);
item1.setText("其他位置");
item1.setHeight(95);// 设置Item的高度
item1.setControl(comp2);// setControl方法控制comp1的显现
}

{
Composite comp3 = new Composite(expandBar,SWT.NONE);
comp3.setLayout(new GridLayout());

// setup bold font
Font boldFont = JFaceResources.getFontRegistry().getBold(JFaceResources.DEFAULT_FONT);
Label l = new Label(comp3,SWT.NONE);
l.setText("我的电脑");
l.setFont(boldFont);

new Label(comp3,SWT.NONE).setText("系统文件夹");

ExpandItem item1 = new ExpandItem(expandBar, SWT.NONE);
item1.setText("详细信息");
item1.setHeight(50);// 设置Item的高度
item1.setControl(comp3);// setControl方法控制comp1的显现
}

shell.layout();
shell.open();

while(!shell.isDisposed()) {
if(!display.readAndDispatch())
display.sleep();
}
display.dispose();
}

public static void main(String[] args) {
new WindowStyle();
}
}

以上程序中会用到7个icon小图片，把他们放置在工程根目录下的icons目录下

运行效果：
