JFrame上的JPanel位置

我在JPanel的位置有問題。我開始創建一個小遊戲......我在設計中創建了2個面板（在JFrame上）。所有的工作都很好，面板都放在正確的地方。在我的遊戲中，我必須使用2個圖形表，所以我使用2個面板，並將其中的每個面板集佈局（new Grid Layout(10,10)）都添加進去。JFrame上的JPanel位置

之後，我運行該項目以瞭解它是如何工作的，並且在其他地方以另一種尺寸發現了我的面板。我發現的方式，可以幫助我改變大小，但我找不到方法來改變位置或給我自己的位置的方式...

我試圖添加圖片，可以告訴你我看到的東西但該網站堵塞的照片...

的代碼是：

public class GameFrame extends javax.swing.JFrame { 
int [][]p1; 
int [][]p1Attac; 
int [][]p2; 
int [][]p2Attac;

@AndrewThompson我認爲[這]（http://i.stack.imgur.com/TiIad.png）是預期的佈局。我只是改變了垂直差距，並將'setVisible（true）'放在構造函數的末尾。我不確定它是否真的是預期的樣子，所以我不想編輯這個問題。 –

一個問題是，在Netbeans的GUI Builder生成的的initComponents（）已經正在由以後運行的代碼搞砸了佈局在構造函數中。解決此問題的方法是使用設計器中的自定義代碼..右鍵單擊菜單選項。將代碼放在那裏將允許您保持由Gui Builder設置的外部設計並添加內部自定義組件。之後，您可以註釋掉構造函數中的所有代碼。

非常感謝！有用！！ – anton

_{感謝@AndrewThompson給了重要的思想對於這個問題（網格佈局，標題的邊框）。我等了大約30分鐘，看看他是否會發布自己的答案。他沒有，所以我決定張貼我自己的 - 我希望沒有人生我的氣。}

不要使用的GroupLayout對於這一點，IMO它只是使事情變得複雜和用戶不友好的（至少在這種情況下）。相反，你可以用簡單的GridLayouts實現一切。（用更少的代碼，可調整大小的）我創建了一個例子，告訴您如何：

import java.awt.Color; 
import java.awt.Font; 
import java.awt.GridLayout; 

import javax.swing.BorderFactory; 
import javax.swing.JFrame; 
import javax.swing.JPanel; 
import javax.swing.border.EmptyBorder; 
import javax.swing.border.LineBorder; 
import javax.swing.border.TitledBorder; 

public class GameFrame { 

    JPanel[][] arrayL = new JPanel[10][10]; 
    JPanel[][] arrayR = new JPanel[10][10]; 

    public GameFrame() { 

     JFrame frame = new JFrame(); 
     frame.getContentPane().setLayout(new GridLayout(1, 2)); 

     JPanel left = new JPanel(new GridLayout(10, 10, 1, 1)); 
     left.setBorder(BorderFactory.createTitledBorder(new EmptyBorder(0, 0, 
       0, 0), "Enemy")); 
     ((TitledBorder) left.getBorder()).setTitleFont(new Font("Arial", Font.BOLD, 20)); 
     addCells(left, arrayL, Color.RED); 

     JPanel right = new JPanel(new GridLayout(10, 10, 1, 1)); 
     right.setBorder(BorderFactory.createTitledBorder(new EmptyBorder(0, 0, 
       0, 0), "You")); 
     ((TitledBorder) right.getBorder()).setTitleFont(new Font("Arial", Font.BOLD, 20)); 
     addCells(right, arrayR, Color.BLUE); 

     JPanel leftPanel = new JPanel(); 
     leftPanel.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20)); 
     leftPanel.setLayout(new GridLayout(1, 1)); 
     leftPanel.add(left); 

     JPanel rightPanel = new JPanel(); 
     rightPanel.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20)); 
     rightPanel.setLayout(new GridLayout(1, 1)); 
     rightPanel.add(right); 

     frame.getContentPane().add(leftPanel); 
     frame.getContentPane().add(rightPanel); 

     frame.setSize(500, 300); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.setVisible(true); 

    } 

    public void addCells(JPanel panel, JPanel[][] array, Color color) { 

     for (int i = 0; i < 10; i++) { 
      for (int j = 0; j < 10; j++) { 

       JPanel p = new JPanel(); 
       p.setBackground(color); 
       p.setBorder(BorderFactory.createLineBorder(Color.BLACK)); 

       array[j][i] = p; 

       panel.add(p); 

      } 
     } 

    } 

    public static void main(String[] args) { 

     new GameFrame(); 

    } 

}
