java - 网格布局列和行不起作用

Question

基本上我试图将两个面板连接到我的框架上，我的框架使用 BorderLayout 并且两个面板将放置在南北方向。我完成了顶部面板，但对于底部面板，我无法正确处理。我在底部使用了 GridLayout，它应该看起来像这样。

这是网格布局的代码

public class WeaponComp extends JPanel{


protected JPanel first = new JPanel();

public WeaponComp(){

    setLayout(new GridBagLayout());
    setPreferredSize(new Dimension(800,550));
    GridBagConstraints c = new GridBagConstraints();
    JLabel ntg = new JLabel("");
    JLabel oldweap = new JLabel("OLD WEAPON");
            JLabel newweap = new JLabel("NEW WEAPON");

    JLabel onetwohand = new JLabel ("1H / 2H");
    JLabel offhand = new JLabel ("Off Hand");
    JLabel dps = new JLabel ("DPS :");
    JLabel str = new JLabel ("Str :");
    JLabel dex = new JLabel ("Dex :");
    JLabel vit = new JLabel ("Vit :");
    JLabel intel = new JLabel ("Int :");
    JLabel manareg = new JLabel ("Mana Regen :");
    JLabel aspd = new JLabel ("Attack Speed:");
    JLabel critch = new JLabel ("Crit chance:");
    JLabel critdmg = new JLabel ("Crit damage:");

    JTextField dpstf = new JTextField(12);
    JTextField strtf = new JTextField(5);
    JTextField dextf = new JTextField(5);
    JTextField vittf = new JTextField(5);
    JTextField inteltf = new JTextField(5);
    JTextField manaregtf = new JTextField(3);
    JTextField aspdtf = new JTextField(3);
    JTextField critchtf = new JTextField(3);
    JTextField critdmgtf = new JTextField(3);
    JTextField offdpstf = new JTextField(12);
    JTextField offstrtf = new JTextField(5);
    JTextField offdextf = new JTextField(5);
    JTextField offvittf = new JTextField(5);
    JTextField offinteltf = new JTextField(5);
    JTextField offmanaregtf = new JTextField(3);
    JTextField offaspdtf = new JTextField(3);
    JTextField offcritchtf = new JTextField(3);
    JTextField offcritdmgtf = new JTextField(3);

    first.setLayout(new GridLayout(3,4));
    first.setPreferredSize(new Dimension(750,150));

    first.add(oldweap); first.add(ntg); first.add(newweap); first.add(ntg);
    first.add(onetwohand); first.add(ntg); first.add(offhand); first.add(ntg);
    first.add(dps); first.add(dpstf); first.add(dps); first.add(offdpstf);


    c.fill = GridBagConstraints.HORIZONTAL;
    c.gridx = 0; c.gridy = 0;
    add (first,c); 

}
}

这是我程序的当前结果

预先感谢您的时间和答复

PS:如果你想知道，是的，它与暗黑破坏神 3 有关但我没有那么雄心勃勃，这是为了学习目的，不会有很多功能。

GridLayout 是一个糟糕的选择，因为所有单元格自动具有相同的大小。我建议改用 MigLayout:http://miglayout.com

布局代码如下所示:

first.setLayout(new MigLayout("wrap 2, fill"));
first.add(oldweap);
first.add(newweap);
first.add(onetwohand);
first.add(offhand);
first.add(dps);
first.add(dpstf);
first.add(dps);
first.add(offdpstf);
