問題jlabel /按鈕格式化

Question

類別標籤1,2,3,4和5似乎不與我分配給他們的行對齊。我不明白問題在哪裏; x值相等。如果有人能帶領我走向正確的方向，那將會非常棒。

這裏是我的代碼

Answer 1

的gridx應該是一個正值，像...

JFrame frame = new JFrame("Jepordy"); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    JPanel panel = new JPanel(new GridBagLayout()); 
    GridBagConstraints c = new GridBagConstraints(); 

    frame.getContentPane().add(panel, BorderLayout.PAGE_START); 

    c.gridx = 0; 

    for (int index = 0; index < 5; index++) { 

     c.gridy = 0; 
     JLabel label = new JLabel("Catagory " + index); 
     c.insets = new Insets(0, 0, 0, 0); 
     panel.add(label, c); 
     c.insets = new Insets(65, 65, 65, 65); 
     for (int cat = 1; cat < 6; cat++) { 
      c.gridy++; 
      panel.add(new JButton(Integer.toString(cat * 100)), c); 
     } 

     c.gridx++; 
    } 
    frame.setVisible(true); 
    frame.setSize(1300, 900); 

例如...

Answer 2

你得到x和y的混合向上。屏幕的左上角是0,0。隨着您向右移動，x增加，隨着您向下移動，y增加。因此，爲您的x座標系分配一個（ - ）值不是必需的，它可能會將您的按鈕從屏幕移動到左邊。每個按鈕，嘗試增加x的網格值，而不是y，你應該得到你想要的結果。

gridx = 10 .... gridx = 20 ..等等。

更好的是，實現某種循環遍歷每個按鈕並在每次迭代時增加x值。或者，查看flowlayout管理器，他們會自動處理這個問題。
