Java的AWT机器人仍然在Windows着preSS非数字键盘箭头？ [英] Java awt Robot still cant press non-numpad arrows on windows?

问题描述

此错误是相识多年，但目前仍处于美元的Java p $ psent 1.7.0_25 这我使用的是Windows 8的下面的结果是版本一样的，不管阉羊的，我有NumLock键开启或不：

This bug is known for years, yet is is still present in Java 1.7.0_25 version which I'm using on Windows 8. The following result are same regardless of wether i have numlock turned on or not:

Robot bot = new Robot();

bot.keyPress(KeyEvent.VK_UP); //this in documentation is non-numpad up arrow key
bot.keyRelease(KeyEvent.VK_UP); //pressed the numpad up arrow key

//folowing line is line #43
bot.keyPress(KeyEvent.VK_KP_UP); //this in documentation is numpad up arrow key
bot.keyRelease(KeyEvent.VK_KP_UP); //causes folowing exception:

Exception in thread "main" java.lang.IllegalArgumentException: Invalid key code
at sun.awt.windows.WRobotPeer.keyPress(Native Method)
at java.awt.Robot.keyPress(Robot.java:358)
at test.RobotArrow.main(RobotArrow.java:43)

我知道这个问题已经被问<一个href=\"http://stackoverflow.com/questions/12565510/java-key$p$pss-arrow-keys-triggers-numpad-keys\">here但在一年前，那么有没有什么进展？我不能谷歌任何东西，甚至有一个 ofiicial bug报告

I know this question was already asked here but over a year ago, so is there any progress? I cant google anything, there is even an ofiicial bug report

那么，有没有一个finnaly溶液或不？

So, is there finnaly a solution or not?

推荐答案

// $ P $ WINDOWS干燥综合征+左箭头

//PRESS WINDOWS + ARROW LEFT

Robot divideWindow = new Robot();
divideWindow.keyPress(KeyEvent.VK_WINDOWS);
divideWindow.delay(100);
divideWindow.keyPress(KeyEvent.VK_LEFT);
divideWindow.delay(100);
divideWindow.keyRelease(KeyEvent.VK_LEFT);
divideWindow.delay(100);
divideWindow.keyRelease(KeyEvent.VK_WINDOWS);

Works fine for me :)
