窗口类：

Window

?

它主要用来显示。

每一个Application可以设置一个主窗口比如：

Window mainWindow = new Window(messageSource.getMessage("main.window",null,Locale.CHINESE));//message为国际化，如果直接输入中文则会乱码。setMainWindow(mainWindow);

还可以向主窗口添加多个子窗口如：

Window window=new Window(messageSource.getMessage("child.window.helloworld", null, Locale.CHINESE));mainWindow.addWindow(window);

可以设置这个窗口的icon

mainWindow.setIcon(icon)//这里需要一个Resource对象来加载图片，Resource的子类中有一个FileResource他的构造需要两个参数，一个是File,一个Application这里如果本身就是在Application 内直接填入this即可如：

mainWindow.setIcon(new FileResource(new File(""),this));

是当前窗口显示后，背后的窗口变为不可使用。

window.setModal(true);

设置是否可以拖拉窗口大小
