发布一个KeyEvent到关注的组件 [英] Post a KeyEvent to the focused component

问题描述

发布按钮的最佳方式是按组件？我尝试使用机器人类，它正常工作。然而，这个类在一些Linux平台下有一些问题，所以我想知道什么是最好的Java唯一的方式来发布事件到一个组件。

What is the best way to post a Button Press to a component? I tried using the Robot class and it works, normally. However, this class has some problems under some Linux platforms, so I wonder what is the best Java-only way to post an event to a component.

在这种情况下当我按下一个按钮时，我想将退格事件发送到JTextField。

In this particular case, I want to post backspace events to a JTextField when I press a button.

编辑：我已经使用了Robot类。我解决了阻止这个类在Linux下正常工作的问题

推荐答案

我最终使用了机器人类，这是最简单的方法。问题是在我正在使用的特定Linux发行版中，Robot类的实例化将挂起虚拟机。查看日志文件，我发现java正在尝试加载一个不可用的DLL：

I ended up using the robot class, which was the easiest way after all. The problem is that in the specific Linux distro I was using, the instantiation of the Robot class would hang the Virtual Machine. Looking at the log files I found out that java was trying to load a DLL that wasn't available:

libXi.so.6

libXi.so.6

将该库添加到发行版后，我可以继续

After adding this library to the distro I was able to continue
