在项目的开发过程中，有些布局是固定的，为了布局的统一，通常会制定一定的模版，每个页面都继承这个模版，这样所有程序的实现都很固定，而且写法都大同小异，从而大大提高了代码的复用率。
1、定义模版的各个类
/** * * @功能:模版主类，做布局之用 * @创建人 gao_jie * @创建日期 Mar 3, 2009 * @版本 1.0 * */ public abstract class WindowTemplet extends Borderlayout implements AfterCompose { /** * 上面框架 */ private Div m_mainCenterNorthDiv;

this.getBorderlayout_navigate().appendChild( this.createNavigateComponent()); this.doWindowTempletInit(); } /** * 窗体返回操作 */ abstract protected void onReturn(); /** * 初始化 */ abstract protected void doWindowTempletInit(); /** * 调用各子窗口处理过程 * * @param command */ protected void processCommand(ConsoleCommand command) { for (Object child : divs) { try { ((ChildWindow) child).processCommand(command); } catch (Exception e) { e.getMessage();

return win; } }/** * * @功能：子窗体类 * @创建人 gao_jie * @创建日期 Mar 3, 2009 * @版本 1.0 * */ public abstract class ChildWindow extends Window { private static final long serialVersionUID = 1L; /** * 构造函数 */ @SuppressWarnings("unchecked") public ChildWindow() { WindowTemplet templet = getParentWindow();
