Question

我有一個GUI在我的主類文件

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

public class TicTac extends JFrame { 
TicTacEvent tictac = new TicTacEvent(this); 
JPanel row1 = new JPanel(); 
JButton[][] boxes = new JButton[4][4]; 
JButton play = new JButton("Play"); 
JButton restart = new JButton("Restart"); 
JTextField blank1 = new JTextField(); 
JTextField blank2 = new JTextField(); 
JOptionPane win = new JOptionPane("Winner"); 
ImageIcon back = new ImageIcon("cardback.jpg"); 

public TicTac() { 
    super ("Tic Tac Toe"); 
    setSize (800,650); 
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    FlowLayout layout = new FlowLayout(); 
    setLayout(layout); 
    int name = 0; 
    String newname; 

    GridLayout layout1 = new GridLayout(5, 4, 10, 10); 
    row1.setLayout(layout1); 
    for (int x=0; x<=3; x++){ 
     for (int y=0; y<=3; y++){ 
      name = name + 1; 
      newname = Integer.toString(name); 
      boxes[x][y] = new JButton(newname); 
      boxes[x][y].setIcon(back); 
      row1.add(boxes[x][y]); 
     } 
    } 
    row1.add(blank1); 
    row1.add(play); 
    row1.add(blank2); 
    row1.add(restart); 
    add (row1); 

    play.addActionListener(tictac); 
    for (int x=0; x<=3; x++){ 
     for (int y=0; y<=3; y++){ 
      boxes[x][y].addActionListener(tictac); 
     } 
    } 


    setVisible(true); 
} 

public static void main(String[] arguments){ 
    TicTac frame = new TicTac();

public void itemStateChanged(ItemEvent e) { 
// throw new UnsupportedOperationException("Not supported yet."); 
} 

public void run() { 
//restart(); 
    //throw new UnsupportedOperationException("Not supported yet."); 

} 


} 

但是我的問題是我怎麼會重置GUI，我有一些想法..

構造函數「Public TicTac」創建gui，但我不知道如何通過另一個類文件再次發生。我OOP的理解是，有一個構造函數，我可以通過這樣assumedly創建一個對象

TicTac restartok = new TicTac(); 

打電話，你會認爲我會創造另一個的JPanel/GUI每次我叫重啓（）;方法，不是？

我的OOP exirence是有限的，所以我沒有線索在哪裏開始或找出什麼邏輯是不正確的。謝謝。

Answer 1

就可以重置遊戲，只是重置clicks爲0和按鈕到其原始狀態，就像它們創建：

boxes[x][y] = new JButton(newname); 
boxes[x][y].setIcon(back); 

除此之外，你有許多的東西在你的代碼來解決。這裏有一些：

• 您的行boxes[x][y].addActionListener(tictac);是在它自己的循環中它應該在初始循環中。沒有理由在相同的數組上迭代兩次。
• 你的佈局決定可能會更好（取決於你想要得到的究竟是）。
• 從invokeLater方法中使用TicTac frame = new TicTac();啓動GUI。
• 爲每個具有獨特功能的按鈕創建一個ActionListener。在你的情況下，播放1，重啓1，所有板按鈕1。
• 您正在使用event.getActionCommand，但您沒有在任何按鈕上撥打setActionCommand。
• 當您檢查按鈕（動作命令名稱），使用if else或更好 - 使用switch語句時，不要使用多個if。
• 請勿爲每個按鈕使用單獨的功能。使用1個接收按鈕作爲參數的函數。
• 當您可以創建本地變量時，請勿創建字段。

如果您需要澄清請給我留言。

編輯：這是一些修改過的代碼，重置按鈕（我無法阻止自己糾正代碼的其他部分，雖然還有更多的事情要做）。

public class TicTac extends JFrame { 

    static JButton[][] boxes = new JButton[4][4];

     } 
    } 

    private class RestartActionListenr implements ActionListener { 

     public void actionPerformed(ActionEvent e) { 

      for (int x = 0; x<=3; x++) { 
       for (int y = 0; y<=3; y++) { 
        boxes[x][y].setText(""+x+y); 
        boxes[x][y].setIcon(back); 
       } 
      } 
     } 
    } 

    public static void main(String[] arguments) { 

     SwingUtilities.invokeLater(new Runnable() { 

      public void run() { 

       new TicTac(); 
      } 
     }); 
    } 
} 

Answer 2

您不需要一次又一次重新創建整個GUI。你需要做的是清除文本域以及用戶迄今爲止所做的任何選擇。因此，您需要創建一個單獨的方法，在其中您將重置GUI中每個按鈕/文本字段的狀態。

例如：要清除textfield您將撥打setText("")方法。

希望這會有所幫助。
