    public class HelloWorld {

	public static void main(String args[]) {
		Shell shell = new Shell();
		shell.setText("Draw2d Hello World");
		shell.pack();	shell.open();
		
		// create content 4 shell.
		createContent4Shell(shell);
		
		while (!shell.isDisposed ()) {
			if (!Display.getDefault().readAndDispatch ())
				Display.getDefault().sleep ();
		}
	}

	private static void createContent4Shell(Shell shell) {
		IFigure panel = new Panel();
		panel.setLayoutManager(new FlowLayout());
		
		for(int i=0; i<100; i++) {
			panel.add(new Label("Label " + i));
		}
		
		LightweightSystem lws = new LightweightSystem(shell);
		lws.setContents(panel);
	}
}
  

FlowLayout布局管理器在swt中也有对应的布局管理器，应用起来也是比较的简单。可以根据外部的窗口大小的变化自动调整内部的布局。

/**
 * Lays out children in rows or columns, wrapping when the current row/column is filled.
 * The aligment and spacing of rows in the parent can be configured.  The aligment and
 * spacing of children within a row can be configured.
