不能使有权重的GridBagLayout位置工作

Question

我正在尝试制作一个3x2的网格。在网格中，我想要一张图片和一个相应的单选按钮。所以图片应该在(0,0)中，图片在(1,0)中。我不能让重量x和重量系统工作，所有的组件都在一条线上。我现在已经去掉了权重。代码如下所示：

    //the two numbers are corresponding with coordinates. For field00, x=0 and y=0
    GridBagConstraints field00 = new GridBagConstraints();
    field00.fill = GridBagConstraints.HORIZONTAL;
    field00.gridx = 0;
    field00.gridy = 0;
    this.add(nokiaPic, field00);
    GridBagConstraints field10 = new GridBagConstraints();
    field10.fill = GridBagConstraints.HORIZONTAL;
    field10.gridx = 1;
    field10.gridy = 0;
    this.add(nokiaButton, field10);

    GridBagConstraints field01 = new GridBagConstraints();
    field01.fill = GridBagConstraints.HORIZONTAL;
    field01.gridx = 0;
    this.add(princessPic, field01);
    GridBagConstraints field11 = new GridBagConstraints();
    field11.gridx = 1;
    field11.gridy = 1;
    this.add(princessButton, field11);

    To give you an idea:
    +--------+--------+
    |        |        |
    |   pic  | Button |
    |        |        |
    +--------+--------+
    |        |        |
    |   pic  | Button |
    |        |        |
    +--------+--------+
    |        |        |
    |   pic  | Button |
    |        |        |
    +--------+--------+

我知道我没有使用GridBagConstraints的常规约定，但我不明白为什么这个方法不能很好地工作。我希望你能帮我添加权重，让它看起来像是图片在左列，相应的单选按钮在右行。

在您的例子中，您可以简单地使用GridLayout，但是如果您仍然想使用GridBagLayout，那么就使用单个GridBagConstraints

    GridBagConstraints gbc = new GridBagConstraints();
    gbc.fill = GridBagConstraints.HORIZONTAL;
    gbc.gridx = 0;
    gbc.gridy = 0;
    this.add(nokiaPic, gbc);
    gbc.gridx = 1;
    this.add(nokiaButton, gbc);
    gbc.gridx = 0;
    gbc.gridy = 1;
    this.add(princessPic, gbc);
    gbc.gridx = 1;
    this.add(princessButton, gbc);
