如何以编程方式将键事件发送到Java App中的任何窗口/进程？ [英] How to programmatically send a key event to any window/process in a Java App?

问题描述

使用Java应用程序，如何以编程方式将键事件（字母，数字，标点符号，箭头等）发送/触发到同一台机器上的窗口/进程？

Using a Java app, how can I programmatically send/trigger a key event (letters,numbers,punctuation, arrows, etc) to a window/process on the same machine?

推荐答案

假设您知道该窗口的位置，您可以使用 java.awt.Robot

Assuming you know a position that window will be you could use java.awt.Robot

这在屏幕上覆盖10,50的任何窗口中键入a。

This types a in whatever window is covering 10,50 on the screen.

Robot r = new Robot();
r.mouseMove(10, 50);
r.mousePress(InputEvent.BUTTON1_MASK);
r.mouseRelease(InputEvent.BUTTON1_MASK);
r.keyPress(KeyEvent.VK_A);
r.keyRelease(KeyEvent.VK_A);

如果您有一个窗口，您知道在10,400处覆盖10,50，另一个在400,400然后这将在不同的窗口中键入xy和z。在我的测试中，我还需要一些延迟才能使其更可靠。

If you had one window you know to cover 10,50 another at 10,400 and another at 400, 400 then this would type x y and z in the different windows. In my testing I also needed some delays before moving to make it more reliable.

Robot r = new Robot();
r.mouseMove(10, 50);
r.mousePress(InputEvent.BUTTON1_MASK);
r.mouseRelease(InputEvent.BUTTON1_MASK);
Thread.sleep(500);
r.keyPress(KeyEvent.VK_X);
r.keyRelease(KeyEvent.VK_X);
Thread.sleep(500);
r.mouseMove(10, 400);
Thread.sleep(500);
r.mousePress(InputEvent.BUTTON1_MASK);
r.mouseRelease(InputEvent.BUTTON1_MASK);
Thread.sleep(500);
r.keyPress(KeyEvent.VK_Y);
r.keyRelease(KeyEvent.VK_Y);
Thread.sleep(500);
r.mouseMove(400, 400);
Thread.sleep(500);
r.mousePress(InputEvent.BUTTON1_MASK);
r.mouseRelease(InputEvent.BUTTON1_MASK);
r.keyPress(KeyEvent.VK_Z);
r.keyRelease(KeyEvent.VK_Z);
