使用Java，如何在不使用GUI组件的情况下检测按键？ [英] Using Java, How to detect keypresses without using GUI components?

问题描述

使用Java，可以在不使用GUI元素的情况下检测用户操作，例如按键，鼠标按钮和/或鼠标的屏幕位置？

Using Java, is it possible to detect user actions, such as key-presses, mouse-button-presses, and/or mouse's screen location, without the use of GUI elements?

如果是，我该如何实现？

If it is, how could I implement it?

否则有哪些替代方案？

我在这个问题上发现的唯一StackOverflow源是这个问题，这是未得到答复的。

The only StackOverflow source i found on this matter is this question, which is unanswered.

StackOverflow在这个问题上指向一个不可见的GUI解决方案，希望是我真的想避免的东西。

And the only sources I found outside StackOverflow on this matter point to an "Invisible GUI" solution, wish is something i really want to avoid.

推荐答案

它可以实现使用JNI和/或JNA，但这不能真正被称为java实现，因为您必须编写平台特定的本机代码。

It can be implemented using JNI and/or JNA but this cannot be really called "java implementation" because you will have to write platform specific native code.

我尝试的替代解决方案是使用全屏透明寡居，正在监听鼠标和键盘的所有事件，并使用类<$ c将其转发到真实的应用程序$ C>机器人。我试过这种方法它适用于一个限制：支持应用程序的鼠标悬停事件有问题：鼠标不会移动到真正的应用程序。它正在移动透明的java窗口。

Alternative solution I tried is to use full screen transparent widow that is listening to all events of mouse and keyboard and "forwards" them to the real application using class Robot. I tried this approach. It works well with one limitation: there is a problem to support "mouse over" events of applications: the mouse is not moving over the real application. It is moving over the transparent java window.
