Java GUI Jpanel不适合内容

Question

有人可以帮我正确显示我的GUI吗？在我创建一个新实例时，GUI显示为一个小框，根本不适合内容。

我创建界面的方法是调用makeFrame方法：

    private void makeFrame()
    {
    frame = new JFrame("game");

    Container contentPane = frame.getContentPane();
    contentPane.setLayout(new BorderLayout());
    contentPane.add(menubar, BorderLayout.NORTH);


    JPanel gamePanel1 = new JPanel();


  buttons = new JButton[boardsize][boardsize];
    mineBoard = new int[9][9];
    for (int a = 0; a < boardsize; a++) 
        for (int b = 0; b < boardsize; b++) {
            buttons[a][b] = new JButton("");
           contentPane.add(buttons[a][b]);
            buttons[a][b].setBounds(30+gridsize*a,30+gridsize*b,gridsize,gridsize);
            buttons[a][b].addMouseListener(new MouseListener(a,b));
            setx(a);
            sety(b);
            settried(false);
            setmine(false);
    }



    assignmines();


   updateGamesPlayed() ;
   UpdateName();
   contentPane.add(gamePanel1, BorderLayout.CENTER);



   Box gamePanel = Box.createVerticalBox();
   add(gamePanel);

    gamePanel.add(nameEnter);
    gamePanel.add(saveName);
    gamePanel.add(namelabel);
    gamePanel.add(scorelabel);
    gamePanel.add(gamesPlayed);
    gamePanel.add(gamesWon);
    gamePanel.add(status);
    gamePanel.add(noMines);
    contentPane.add(gamePanel, BorderLayout.EAST);

    contentPane.add(status, BorderLayout.SOUTH);


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

    makeMenuBar();
}

如何让Jpanels适应内容？

Answer 1

尝试：

frame . setSize ( height , width ) ; 

或：

frame . setPreferredSize ( dimension ) ;
