本文整理了Java中org.eclipse.swt.widgets.Widget.getData()方法的一些代码示例，展示了Widget.getData()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Widget.getData()方法的具体详情如下：
包路径：org.eclipse.swt.widgets.Widget
类名称：Widget
方法名：getData

Widget.getData介绍

[英]Returns the application defined widget data associated with the receiver, or null if it has not been set. The widget data is a single, unnamed field that is stored with every widget.

Applications may put arbitrary objects in this field. If the object stored in the widget data needs to be notified when the widget is disposed of, it is the application's responsibility to hook the Dispose event on the widget and do so.
[中]返回与接收器关联的应用程序定义的小部件数据，如果尚未设置，则返回null。小部件数据是一个单独的未命名字段，与每个小部件一起存储。
应用程序可以在该字段中放置任意对象。如果在处理小部件时需要通知存储在小部件数据中的对象，则应用程序有责任将Dispose事件挂接到小部件上并执行此操作。
