如何将JDialog链接到JButton单击

Question

我在eclipse上使用窗口构建器，我正在尝试使Button打开JDialog。我花了很多时间筛选帖子和谷歌搜索，我拉的任何东西都解决了我的问题。

JButton btnNewButton = new JButton("New button");
    btnNewButton.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
              ApiKeyEntryDialog.setVisible(true);
        }
    });

带按钮的主JFrame。

private JFrame frame;

/**
 * Launch the application.
 */
public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                FrontPage window = new FrontPage();
                window.frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

/**
 * Create the application.
 */
public FrontPage() {
    initialize();
}

/**
 * Initialize the contents of the frame.
 */
private void initialize() {
    frame = new JFrame();
    frame.setBounds(100, 100, 1377, 789);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.getContentPane().setLayout(null);

    JMenuBar menuBar = new JMenuBar();
    menuBar.setBounds(0, 0, 1361, 21);
    frame.getContentPane().add(menuBar);

    JMenu mnFile = new JMenu("File");
    menuBar.add(mnFile);

    JMenu mnTools = new JMenu("Tools");
    menuBar.add(mnTools);

    JMenu mnView = new JMenu("View");
    menuBar.add(mnView);

    JMenu mnHelp = new JMenu("Help");
    menuBar.add(mnHelp);

    JTabbedPane MainTabbedPane = new JTabbedPane(JTabbedPane.TOP);
    MainTabbedPane.setBounds(0, 21, 1361, 729);
    frame.getContentPane().add(MainTabbedPane);

    JPanel MainTab = new JPanel();
    MainTabbedPane.addTab("Main", null, MainTab, null);
    MainTab.setLayout(null);

    JButton btnNewButton = new JButton("New button");
    btnNewButton.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
              ApiKeyEntryDialog.setVisible(true);
        }
    });
    btnNewButton.setBounds(10, 11, 89, 23);
    MainTab.add(btnNewButton);

    JPanel AssetsTab = new JPanel();
    MainTabbedPane.addTab("Assets", null, AssetsTab, null);

    JPanel BuyOrdersTab = new JPanel();
    MainTabbedPane.addTab("Buy Orders", null, BuyOrdersTab, null);

    JPanel SellOrdersTab = new JPanel();
    MainTabbedPane.addTab("Sell Orders", null, SellOrdersTab, null);

    JPanel JitaTab = new JPanel();
    MainTabbedPane.addTab("Jita", null, JitaTab, null);


}

按下按钮时我想弹出的JDialog帧。

public static void showConfirmationDialog(boolean b) {

}

我习惯于剪切和粘贴宏的VB代码，但Java invirontment的行为不一样。尝试修改和插入示例中的不同代码并没有奏效。

请您替换FrontPage课程中的以下代码段：

btnNewButton.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
              ApiKeyEntryDialog.setVisible(true);
        }
    });

通过以下代码片段：

btnNewButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                ApiKeyEntryDialog dialog = new ApiKeyEntryDialog();
                dialog.setVisible(true);
            }
        });

并告诉我结果？
