包路径：org.eclipse.swt.widgets.Widget
类名称：Widget

Widget介绍

[英]This class is the abstract superclass of all user interface objects. Widgets are created, disposed and issue notification to listeners when events occur which affect them. Styles: (none) Events: Dispose

IMPORTANT: This class is intended to be subclassed only within the SWT implementation. However, it has not been marked final to allow those outside of the SWT development team to implement patched versions of the class in order to get around specific limitations in advance of when those limitations can be addressed by the team. Any class built using subclassing to access the internals of this class will likely fail to compile or run between releases and may be strongly platform specific. Subclassing should not be attempted without an intimate and detailed understanding of the workings of the hierarchy. No support is provided for user-written classes which are implemented as subclasses of this class.
[中]此类是所有用户界面对象的抽象超类。小部件被创建、处理，并在发生影响它们的事件时向侦听器发出通知。样式：（无）事件：Dispose
重要提示：该类仅在SWT实现中被子类化。然而，允许SWT开发团队之外的人实现类的补丁版本，以便在团队能够解决这些限制之前绕过特定的限制，这还没有被标记为最终版本。任何使用子类化来访问该类内部的类都可能无法编译或在不同版本之间运行，并且可能是非常特定于平台的。如果没有对层次结构的工作原理有深入而详细的了解，就不应该尝试子类化。不支持作为此类子类实现的用户编写的类。
