SWING设置快捷键

SWING设置快捷键,不难,看代码好了
关键就是这两行了:
---
        btn.registerKeyboardAction(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                JOptionPane.showMessageDialog(null, "hello world");
            }
        }, KeyStroke.getKeyStroke(KeyEvent.VK_F10, InputEvent.CTRL_DOWN_MASK), JComponent.WHEN_IN_FOCUSED_WINDOW);
---
红色是组合键,推荐用一下CTRL 或者 SHIFT,不用就用0代替[InputEvent.CTRL_DOWN_MASK],
蓝色一定要,说明本窗口激活时,这对快捷键才有用.
