java - Java JOptionPane

我正在用Java创建基于Tic Tac Toe GUI的游戏，并且正在努力将2D数组与JOptionPane结合使用。到目前为止，我已经能够创建按钮以供选择：

import java.awt.GridLayout;
import javax.swing.*;

public class YourHEad {

    public static void main(String[] args) {
    JFrame frame = new JFrame("GridLayout Test");
    frame.setLayout(new GridLayout(4, 4));

StringBuilder sb = new StringBuilder();
sb.append("<html>");

String[][] seats = new String [4][4];
String alpha = "ABCD";

for (int i=0; i<4; i++){

    String letter = Character.toString(alpha.charAt(i));

    for (int j=0; j<4; j++){

        String number = Integer.toString(j+1);
        seats [i][j]=letter+number+" ";

    }
}

for (int i = 0; i < 4; i++){
    for (int j = 0; j < 4; j++){
         frame.add(new JButton(seats[i][j]));
    }
}

frame.pack();
frame.setVisible(true);

if(new JButton(seats[0][0]).getModel().isPressed()){
    System.out.println("the button is pressed");
}

}}

从最后几行代码中您可以看到，我正在尝试弄清楚如何知道何时按下了按钮，例如，如果用户单击“ A1”（因此单击0,0），则该程序可以输出文本（我将其更改为JOptionPane格式）。

希望我已经解释清楚了。

最佳答案

希望，这会有所帮助

 public class YourHEad
{

    public static void main(String[] args)
    {
    final JFrame frame = new JFrame("GridLayout Test");
    frame.setLayout(new GridLayout(4, 4));

    StringBuilder sb = new StringBuilder();
    sb.append("<html>");

    String[][] seats = new String [4][4];
    String alpha = "ABCD";

    for (int i=0; i<4; i++){

        String letter = Character.toString(alpha.charAt(i));

        for (int j=0; j<4; j++){

            String number = Integer.toString(j+1);
            seats [i][j]=letter+number+" ";

        }
    }

for (int i = 0; i < 4; i++){
    for (int j = 0; j < 4; j++){
        JButton button= new JButton(seats[i][j]);
        button.addMouseListener(new MouseAdapter()
                {
                    public void mouseClicked(MouseEvent e)
                    {
                        JOptionPane.showMessageDialog(frame, ((JButton)(e.getSource())).getText()+" is Pressed");
                    }
                });
         frame.add(button);
    }
}

frame.pack();
frame.setVisible(true);

}
}
