Netbeans 中 Swing 组件的变量名 [英] Variable name of Swing component in Netbeans

问题描述

我有一个应用程序，目前使用了 200 多个按钮，每个按钮都返回其变量名称的字符串.有没有办法做到这一点?为每一个设置 name 属性会非常耗时.

I have an application that is currently using over 200 buttons, each of which returns the String of their variable name. Is there any way to do this? Setting the name property for each of these would be far too time consuming.

推荐答案

使用按钮集合:

ActionListener theActionListener = new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println(((JButton) e.getSource()).getName());
    }
};

List<JButton> buttons = new ArrayList<JButton>();
for (int i = 0; i < 200; i++) {
    JButton button = new JButton("Button " + (i + 1));
    button.setName("Button " + (i + 1));
    button.addActionListener(theActionListener);
    buttons.add(button);
}
