本文整理了Java中java.awt.event.ActionEvent类的一些代码示例，展示了ActionEvent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。ActionEvent类的具体详情如下：
包路径：java.awt.event.ActionEvent
类名称：ActionEvent

ActionEvent介绍

[英]A semantic event which indicates that a component-defined action occured. This high-level event is generated by a component (such as a Button) when the component-specific action occurs (such as being pressed). The event is passed to every every ActionListener object that registered to receive such events using the component's addActionListener method.

The object that implements the ActionListener interface gets this ActionEvent when the event occurs. The listener is therefore spared the details of processing individual mouse movements and mouse clicks, and can instead process a "meaningful" (semantic) event like "button pressed".

Note: The timestamps used by this class report the difference, measured in milliseconds, between the time of the event and midnight, January 1, 1970 UTC (similar to java.lang.System.currentTimeMillis).
[中]一个语义事件，指示发生了组件定义的操作。此高级事件由组件（如按钮）在特定于组件的操作发生（如被按下）时生成。该事件将传递给使用组件的addActionListener方法注册以接收此类事件的每个ActionListener对象。
当事件发生时，实现ActionListener接口的对象将获得此ActionEvent。因此，监听器不需要处理单个鼠标移动和鼠标单击的细节，而是可以处理“有意义”（语义）事件，如“按下按钮”。
注意：此类使用的时间戳报告事件时间与UTC 1970年1月1日午夜之间的差异（以毫秒为单位）（类似于java.lang.System.currentTimeMillis）
