Swing/Applet
使用eclipse的插件，首先設(shè)計(jì)form。然后可以把自己的code，后臺(tái)操作的代碼寫入到form的code中.
但是要注意:
/** *//** This method is called from within the constructor to
* initialize the form.
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.
*/提醒不能修改的地方是不能加入自己的code去修改界面的外觀, 即使加入，也不會(huì)有什么效果。因?yàn)閙atisse的編輯器回重新生成代碼。但可以加入控制代碼。而且event響應(yīng)事件的代碼是在這些代碼之前生成. 對(duì)于起始要調(diào)用的代碼可以加到form的init（）或constructor method中. 對(duì)于后臺(tái)要access到前臺(tái)界面的control時(shí)，可以用setter／getter方法調(diào)用屬性為private的controls
