    panelMain.add(new JButton("1,0"),c);

    c.gridx = 0;
    c.gridy = 1;
    panelMain.add(new JButton("0,1"),c);

我很高兴看到由此产生的UI:

我想JButton在一个未连接到现有单元格的单元格中添加一个.我希望它被一个空的空间分开.当我尝试这个时,新的东西JButton被压在其他的旁边.这是补充:

JPanel panelMain = new JPanel(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
    c.gridx = 0;

    panelMain.add(new JButton("0,0"),c);

    c.gridx = 1;
    c.gridy = 0;
    panelMain.add(new JButton("1,0"),c);

    c.gridy = 1;
    panelMain.add(new JButton("0,1"),c);

    c.gridx …
