本文整理了Java中org.eclipse.jface.util.PropertyChangeEvent类的一些代码示例，展示了PropertyChangeEvent类的具体用法。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。PropertyChangeEvent类的具体详情如下：
包路径：org.eclipse.jface.util.PropertyChangeEvent
类名称：PropertyChangeEvent

PropertyChangeEvent介绍

[英]An event object describing a change to a named property.

This concrete class was designed to be instantiated, but may also be subclassed if required.

The JFace frameworks contain classes that report property change events for internal state changes that may be of interest to external parties. A special listener interface (IPropertyChangeListener) is defined for this purpose, and a typical class allow listeners to be registered via an addPropertyChangeListener method.
[中]描述命名属性更改的事件对象。
这个具体的类是为了实例化而设计的，但是如果需要的话也可以被子类化。
JFace框架包含一些类，这些类报告外部各方可能感兴趣的内部状态更改的属性更改事件。为此定义了一个特殊的侦听器接口（IPropertyChangeListener），典型的类允许通过addPropertyChangeListener方法注册侦听器。
