Java JOptionPane.showConfirmDialog 热键

我正在使用 JOptionPane.showConfirmDialog 在 Java 中显示确认对话框。该对话框向用户显示是否确认。调用方式如下：

int result = JOptionPane.showConfirmDialog(sessionObjects.getActiveComponent(), 
                 "Are you sure you want to exit?", "My App", JOptionPane.YES_NO_OPTION);

问题是，这是一个简单的确认，用户是否可以按y表示是，按n表示否？目前用户必须点击按钮？

谢谢，

I am displaying a confirmation dialog in Java using JOptionPane.showConfirmDialog. The dialog shows a Yes No confirmation to the user. This is called as follows:

int result = JOptionPane.showConfirmDialog(sessionObjects.getActiveComponent(), 
                 "Are you sure you want to exit?", "My App", JOptionPane.YES_NO_OPTION);

The question is as this is a simple confirmation, can the user press y for yes and n for no? At present the user has to click on the buttons?

Thanks,

Andez

还有另一种更简单的可能性：您可以在程序中按 alt ，然后以相同的方式释放它：

public static void pressAlt(){
    try {
        Robot r = new Robot();
        r.keyPress(KeyEvent.VK_ALT);
    } catch (AWTException ex) {
        Logger.getLogger(ManualDetection.class.getName()).log(Level.SEVERE, null, ex);
    }
}

public static void releaseAlt(){
    try {
        Robot r = new Robot();
        r.keyRelease(KeyEvent.VK_ALT);
    } catch (AWTException ex) {
        Logger.getLogger(ManualDetection.class.getName()).log(Level.SEVERE, null, ex);
    }
}

然后当您调用时：

 pressAlt();
 int confirm = JOptionPane.showConfirmDialog(... bla bla bla ... 
                                                  ,JOptionPane.YES_NO_OPTION);
 releaseAlt();

行为完全相同，如您所愿......

There is another simpler possibility: you can press alt in a program and then release it in a same way:

public static void pressAlt(){
    try {
        Robot r = new Robot();
        r.keyPress(KeyEvent.VK_ALT);
    } catch (AWTException ex) {
        Logger.getLogger(ManualDetection.class.getName()).log(Level.SEVERE, null, ex);
    }
}

public static void releaseAlt(){
    try {
        Robot r = new Robot();
        r.keyRelease(KeyEvent.VK_ALT);
    } catch (AWTException ex) {
        Logger.getLogger(ManualDetection.class.getName()).log(Level.SEVERE, null, ex);
    }
}

then when you call:

 pressAlt();
 int confirm = JOptionPane.showConfirmDialog(... bla bla bla ... 
                                                  ,JOptionPane.YES_NO_OPTION);
 releaseAlt();

the behavior is exactly the same, as you desired...
