我有一个JFrame，我需要添加面板到它我喜欢的地方，但我不知道该怎么做。我试过所有的布局，但我不能得到我想要的。麻烦简单JPanels

基本上程序化是主框架，我需要在那个框架上的3个其他面板。我需要一个在中间/右边。我需要一个面板在左边，一个在底部，在框架的1/3左右。尝试不同的布局管理器后，我不知道如何去这样做（也对不起，我似乎无法给两个班分开，第一个现在缺少{）

回答：

您可以让您的主框架成为BorderLayout。

将您ConsolePanel如下：

frame.add(consolePanel, BorderLayout.WEST); 
consolePanel.setPreferredSize(100, 400);

我猜你就可以把它从那里。

回答：

你可以尝试这样的事情：

public class Test { 
public static void main(String[] args) { 
    SwingUtilities.invokeLater(new Runnable() { 
     @Override 
     public void run() { 
      JFrame f = new JFrame(); 
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
      MBar mBar = new MBar(); 
      TextAreaPanel scrPan = new TextAreaPanel(); 
      BottomPan pan = new BottomPan(); 
      ButtonsPanel buttsCon = new ButtonsPanel(); 
      f.setJMenuBar(mBar); 
      f.getContentPane().add(buttsCon, BorderLayout.LINE_START); 
      f.getContentPane().add(scrPan, BorderLayout.CENTER); 
      f.getContentPane().add(pan, BorderLayout.PAGE_END); 
      f.pack(); 
      f.setVisible(true); 
     } 
    }); 
    } 
}

ButtonsPanel.java

public class ButtonsPanel extends JPanel { 
    public ButtonsPanel() { 
     setLayout(new BoxLayout(this, BoxLayout.X_AXIS)); 
     add(Box.createHorizontalStrut(50)); 
     JPanel butts = new JPanel(); 
     butts.setLayout(new BoxLayout(butts, BoxLayout.Y_AXIS)); 
     butts.add(Box.createVerticalStrut(30)); 
     for (int i = 0; i < 5; i++) { 
      JButton butt = new JButton("Button " + String.valueOf(i)); 
      butts.add(butt); 
      butts.add(Box.createVerticalStrut(10)); 
     } 
     butts.setAlignmentY(JPanel.TOP_ALIGNMENT); 
     butts.add(Box.createVerticalStrut(40)); 
     add(butts); 
     add(Box.createHorizontalStrut(50)); 
    } 
}

TextAreaPanel.java

public class TextAreaPanel extends JScrollPane { 
    public TextAreaPanel() { 
     JTextArea jtxtArea = new JTextArea(); 
     setViewportView(jtxtArea); 
    } 
}

BottomPan.java

public class BottomPan extends JPanel { 
    public BottomPan() { 
     setBackground(Color.black); 
     setPreferredSize(new Dimension(100, 100)); 
    } 
}

MBar.java

public class MBar extends JMenuBar { 
    public MBar() { 
     for (int i = 0; i < 5; i++) { 
      JMenuItem mi = new JMenuItem("Menu Item " + String.valueOf(i)); 
      add(mi); 
     } 
    } 
}
