Question

我想让我的JFX应用程序模拟箭头键按下（当它们在TextField中注册时），但我无法弄清楚如何发送除字符串或字节之外的任何内容。

我想象这样的事情：

static EventHandler<KeyEvent> KEY() {
    E = new EventHandler<KeyEvent>() {
        @Override
        public void handle(KeyEvent ke) {
            if (ke.getCode().equals(KeyCode.UP)) {
                try {
                    //someObject.SimulateKeyPress(KeyCode.UP);

                    //OR

                    //coolObject.SendKey((char)KEY_UPKEY));
                } catch (Exception ex) {
                    //Teleport goats
                }
            }
        }
    };

    return E;
}

Answer 1

使用课程Robot

 try {
    Robot r = new Robot();
    //there are other methods such as positioning mouse and mouseclicks etc.
    r.keyPress(java.awt.event.KeyEvent.VK_UP);
    r.keyRelease(java.awt.event.KeyEvent.VK_UP);
 } catch (AWTException e) {
    //Teleport penguins  
 }

您无法实例化Robot类型。你应该做：

  Robot robot = com.sun.glass.ui.Application.GetApplication().createRobot();
