    Shell shell = new Shell(display);
    CoolBar coolBar = new CoolBar(shell, SWT.BORDER);
    coolBar.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

    final CoolItem item = new CoolItem(coolBar, SWT.DROP_DOWN);

    Composite c = new Composite(coolBar, SWT.NONE);
    c.setLayout(new GridLayout(1, false));
    new Button(c, SWT.PUSH).setText("Button One");
    new Button(c, SWT.PUSH).setText("Button Two");


    Control control = item.getControl();
    Point pt = control.computeSize(SWT.DEFAULT, SWT.DEFAULT);
    pt = item.computeSize(pt.x, pt.y);

    while (!shell.isDisposed()) {
      if (!display.readAndDispatch())
