使用Java Robot的Alt + Tab [英] Alt+Tab using Java Robot

问题描述

我正在尝试使用Java Robot弹出 alt + tab 菜单.当我调用alt_tab()方法时，我想调出 alt + tab 菜单并保持菜单不变.我知道可以使用 alt + ctrl + tab 来实现.

I am trying to bring up the alt+tab menu with a Java Robot. When I call the alt_tab() method, I want to bring up the alt+tab menu and keep the menu up. I know this can be achieved using alt+ctrl+tab.

到目前为止，我已经尝试了下面的代码，并且只尝试了 alt + tab ，而没有控制键.我不确定为什么不显示菜单.它所做的只是模拟按Alt键.

So far I have tried the code below, and also just alt+tab without the control key. I am not sure why it's not bringing up the menu. All it does is emulate pressing the alt key.

public void alt_tab() {
    Robot robot = new Robot();
    robot.keyPress(KeyEvent.VK_ALT);
    robot.keyPress(KeyEvent.VK_CONTROL);
    robot.keyPress(KeyEvent.VK_TAB);
    robot.delay(100);
    robot.keyRelease(KeyEvent.VK_TAB);
    robot.keyRelease(KeyEvent.VK_CONTROL);
    robot.keyRelease(KeyEvent.VK_ALT);
}

我正在使用Windows 8 Pro和JDK7.不胜感激！
