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

FocusListener介绍

[英]The listener interface for receiving keyboard focus events on a component. The class that is interested in processing a focus event either implements this interface (and all the methods it contains) or extends the abstract FocusAdapter class (overriding only the methods of interest). The listener object created from that class is then registered with a component using the component's addFocusListener method. When the component gains or loses the keyboard focus, the relevant method in the listener object is invoked, and the FocusEvent is passed to it.
[中]用于接收组件上的键盘焦点事件的侦听器接口。对处理焦点事件感兴趣的类要么实现此接口（及其包含的所有方法），要么扩展抽象FocusAdapter类（仅覆盖感兴趣的方法）。然后使用组件的addFocusListener方法向组件注册从该类创建的侦听器对象。当组件获得或失去键盘焦点时，将调用侦听器对象中的相关方法，并将FocusEvent传递给它。
