GridBagLayout中的JTextArea竊取太多空間

我有一個GridBagLayout，出於某種原因，我的JTextArea已經決定它不想偵聽gridbag的比率，並且當創建包含佈局的面板時，我的文本框會長大到它佔用了屏幕的1/2。下面是一些代碼：GridBagLayout中的JTextArea竊取太多空間

 tp = new JTabbedPane(); 
     tp.setFont(Main.f); 
     //Adds tabs with several buttosn to my tabbed pane 
     for(Menu menu : FileManager.menus){ 
      JPanel tmp = new JPanel(); 
      int s = (int) Math.ceil(Math.sqrt(menu.products.size())); 
      tmp.setLayout(new GridLayout(s,s)); 
      for(Product p : menu.products){//Act as 
       p.setFont(Main.f); 
       p.addActionListener(this); 
       tmp.add(p); 
      } 
      tp.addTab(menu.name,null,tmp,null); 
     } 
     receipt.setBorder(BorderFactory.createEtchedBorder()); 

     //starting up with GridBag 
     setLayout(new GridBagLayout()); 
     GridBagConstraints gbc = new GridBagConstraints(); 
     gbc.fill = GridBagConstraints.BOTH; 
     gbc.ipadx = 0; 
     gbc.ipady = 0; 

     //sets up and adds the JTabbedPane 
     gbc.gridx = 0; 
     gbc.gridy = 0; 
     gbc.gridwidth = 1; 
     gbc.gridheight = 1; 
     gbc.weightx = 0.8; 
     gbc.weighty = 0.8; 
     add(tp,gbc); 

     //sets up and adds receipt - The one that takes up half the screen 
     gbc.fill = GridBagConstraints.BOTH; 
     gbc.gridx = 1; 
     gbc.gridy = 0; 
     gbc.weightx = 0.2; 
     receipt.setEditable(false); 
     receipt.setText("Ticket number: 0\n" + 
       "Transaction number: 0\n"); 
     receipt.setLineWrap(true); 
     add(receipt,gbc); 

     //sets up and adds a JPanel that has a bunch of buttons on it(Uses gridlayout) 
     gbc.fill = GridBagConstraints.BOTH; 
     gbc.gridx = 0; 
     gbc.gridy = 1; 
     gbc.gridwidth = 2; 
     gbc.gridheight = 1; 
     gbc.weightx = 1; 
     gbc.weighty = 0.2; 
     add(buttons,gbc); 

     buttons.setLayout(new GridLayout(1,8)); 
     createButton(newtable); 
     createButton(remove); 
     for(JButton a : quicks) 
      createButton(a); 
     createButton(pay); 
     createButton(exit); 

     revalidate(); 
     repaint();

當我將TextArea更改爲空白JButton時，它根本不佔用太多空間。基本上空間是由右側的物體填充的。我如何告訴gridbag，我希望我的左對象跨越屏幕的四分之五，並且正確的對象跨越最後的1/5？在這個版本中，我嘗試使用加權來實現，在我的原始版本中，我嘗試使用單元格進行操作，所以左側對象位於gridx = 0 gridwidth = 4，右側對象是gridx = 4 gridwidth = 1

這兩種方法都無效。我也開到備用的想法（比如更好的佈局，或者一個JTable？）
