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

Spinner.addSelectionListener介绍

[英]Adds the listener to the collection of listeners who will be notified when the control is selected by the user, by sending it one of the messages defined in the SelectionListener interface.

widgetSelected is not called for texts. widgetDefaultSelected is typically called when ENTER is pressed in a single-line text.
[中]通过发送SelectionListener界面中定义的消息之一，将侦听器添加到侦听器集合中，当用户选择控件时，将通知这些侦听器。
widgetSelected不需要短信。在单行文本中按ENTER键时通常会调用widgetDefaultSelected。
