“选项窗格”对话框错误

Question

我收到以下错误消息:

The method showMessageDialog(Component, Object, String, int, Icon) in the type 
   JOptionPane is not applicable for the arguments (JFrame, String, String, int, int, ImageIcon, String) 

当我将鼠标悬停在JOptionPane.showMessageDialog上时。我学习了java教程，不知道问题出在哪里。知道吗？

Java 教程：http://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html#button

String option = "Restart";
JFrame frame = new JFrame();
ImageIcon ic = new ImageIcon("hangmanIcon.png");
JOptionPane.showMessageDialog(frame,
        "He's dead, game over. The word was " + wordList[level],
        "You Lost",
        JOptionPane.OK_OPTION,
        JOptionPane.INFORMATION_MESSAGE,
        ic,
        option);

适用于 JOptionPane 的 Java API 将告诉您哪些方法签名可用/允许，而该方法签名不是一个。您可能希望改用这个：

public static void showMessageDialog(Component parentComponent,
                 Object message,
                 String title,
                 int messageType,
                 Icon icon)
                          throws HeadlessException

也许你想使用的不是显示消息对话框，而是显示选项对话框，它确实允许更多参数。

String[] options = {"Restart", "Exit"};
String option = options[0];
JFrame frame = new JFrame();
ImageIcon ic = new ImageIcon("hangmanIcon.png");
JOptionPane.showMessageDialog(frame,
        "He's dead, game over. The word was " + wordList[level],
        "You Lost",
        JOptionPane.OK_OPTION,
        JOptionPane.INFORMATION_MESSAGE,
        ic,
        options,
        option);
