将Java组件以相同的布局上方和并排放置在gridbaglayout上

Question

我有一个JSliders和JTextfields数组，我想在下面放置一个JTextfield然后是一个JSlider，向左移动并再次放置下一个JTextfield，即Jslider。

        setLayout(new GridBagLayout());

        JTextField[] textField = new JTextField[NUM_CHANNELS + 1];

        JSlider[] sliders = makeSliders(NUM_CHANNELS + 1);

        for (int i = 0; i < NUM_CHANNELS + 1; i++) {

            textField[i] = new JTextField();

            textField[i].setText("Channel " + (i + 1));

            add(textField[i]);

            add(sliders[i]);
        }

有了以上内容，我连续获得了JTextField-JSlider...。

添加组件时需要添加GridBagConstraints

   GridBagConstraints gbc = new GridBagConstraints();
   for (int i = 0; i < NUM_CHANNELS + 1; i++) {
        gbc.gridy = 0;
        textField[i] = new JTextField();

        textField[i].setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 0));

        textField[i].setText("Channel " + (i + 1));

        add(textField[i], gbc);
        gbc.gridy = 1;
        add(sliders[i], gbc);
        gbc.gridx++;
    }
