Question

类别标签1,2,3,4和5似乎与第I行对齐，而不是分配给它们。我不明白问题所在; x值相等。如果有人能引导我朝着正确的方向发展，那将会非常棒。

这是我的代码

Answer 1

gridx应为正值，例如......

    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);

Answer 2

你得x和y混淆了。屏幕的左上角是0,0。当你向右移动时，x增加，当你向下移动时，y增加。因此，不需要为x坐标系指定（ - ）值，它可能会开始移动屏幕左侧的按钮。每个按钮，尝试增加x网格值，而不是y，你应该得到你想要的结果。

gridx = 10 .... gridx = 20 ..依此类推。

更好的是，实现某种循环来迭代每个按钮并在每次迭代时增加x值。

或者，查看flowlayout经理，他们会自动处理。
