摘要: 使用Eclipse进行SWT编程（5）
8.3. 组合窗口组件Composite Widgets
组合窗口组件可以容纳其他的组合窗口组件。Composite类是组合窗口组件的父类。
图 10. Composite可以容纳其他的组合类
组合类可以容纳其他的组合类。这种容纳关系是用一个组合窗口组件类的构造函数来建造的。与Swing相比，SWT没有add() 方法；作为代替，你必须使用构造函数来建立包容关系结构。
正如图10中所看到的，Shell类也是一个组合类。也就是说，Shell对象，可以容纳其他的组合类。
组合类是可以卷起的，也就是说可以使用SWT.H_SCROLL和SWT.V_SCROLL常量给组合窗口组件加上滚动条。
8.3.1. Table窗口组件
Table窗口组件可以显示一批字符串项或者图片。与其他的组合窗口组件相比，不能给table窗口组件增加组合控件。Table窗口组件的子构件必须是TableItem类型的。

Combo窗口组件允许用户从值列表中选择一个值或者随意输入一个新值。组合框（combo）类似于列表组件，却使用了有限的空间。
虽然组合框是组合性质的，但是对它增加子元素是没有意义的。它的元素必须是String类型。一元素可以使用Combo类中定义的add(String element)方法来添加到组合框中。
