我正在寻找从 ESC 和 F2 键识别两个击键。以下是我在按下转义键时的识别方式：

// Enable escape to close the window by first returning the rootPane object for this frame, then the InputMap that is usedduring condition i.e. JComponent.WHEN_IN_FOCUSED_WINDOW
    // and then use function put to add a binding for keyStroke to actionMapKey
    frame.getRootPane().getInputMap(JComponent. WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0), "Cancel");

    // Kill the AuotIt script when closing the window by first returning the rootPane object for this frame then the ActionMap used to determine what Action 
    // to fire for particular KeyStroke binding. The returned ActionMap, unless otherwise set, will have the ActionMap from the UI set as the parent.
    frame.getRootPane().getActionMap().put("Cancel", new AbstractAction(){
        public void actionPerformed(ActionEvent x) {
            // Undertake some action here
        }
    });

我尝试了完全相同的事情，但是将 keyevent 更改为 F2 但是当我按下 F2 按钮时没有任何反应。以下是我尝试识别 F2 的方式：

frame.getRootPane().getInputMap(JComponent.WHEN_FOCUSED).put(KeyStroke.getKeyStroke(KeyEvent.VK_F2, 0), "pressed");

    // 
    frame.getRootPane().getActionMap().put("pressed", new AbstractAction(){
        public void actionPerformed(ActionEvent x) {

            // Change the hasusersetcomport flag in hasusersetcomport.txt to 0
            notifyScriptThatUserNeedsCOMPorts("0");

            // Notify Script That User Pressed Allow Pairing (which is the default setting for wasallowpairingpressed.txt) 
            notifyScriptThatUserPressedAllowPairing("1");

            // Write menu Item Event Control ID
            RFC95.writeMenuItemEventControlID("8");

            // Write empty string into config file
            writeUserSelectedCOMportIntoConfigFile("");

            // Notify user that current pairing has been deleted
            notifMssgLabel.setText("<html><p>CURRENT PAIRING SETTING DELETED. WINDOW CLOSING</p></html>");
            notifMssgLabel.setForeground(officialSuccessFontColour);
            notifMssgLabel.setFont(officialFontBold);

            // Change the hasusersetcomport flag in hasusersetcomport.txt to 0
            notifyScriptThatUserNeedsCOMPorts("0");

            panelTimer.start();
        }
    });

关于我为什么遇到问题的任何想法。

谢谢。
