包路径：org.eclipse.swt.widgets.ScrollBar
类名称：ScrollBar
方法名：addSelectionListener

ScrollBar.addSelectionListener介绍

[英]Adds the listener to the collection of listeners who will be notified when the user changes the receiver's value, by sending it one of the messages defined in the SelectionListener interface.

When widgetSelected is called, the event object detail field contains one of the following values: SWT.NONE - for the end of a drag. SWT.DRAG. SWT.HOME. SWT.END. SWT.ARROW_DOWN. SWT.ARROW_UP. SWT.PAGE_DOWN. SWT.PAGE_UP. widgetDefaultSelected is not called.
[中]将侦听器添加到侦听器集合中，当用户更改接收方的值时，将通过向其发送SelectionListener界面中定义的消息之一来通知这些侦听器。
调用widgetSelected时，事件对象详细信息字段包含以下值之一：[$2$]-用于拖动结束。SWT.DRAG. SWT.HOME. SWT.END. SWT.ARROW_DOWN. SWT.ARROW_UP. SWT.PAGE_DOWN. SWT.PAGE_UP. 未调用widgetDefaultSelected。
