Java GridBagConstraints问题向左移动，大小为'；不一样

我在Java中有两个面板，它们需要有相同的布局，还有我的初始化面板的函数

private void InitializePanelCom(){
        pnlCom=new JPanel();
        pnlCom.setSize(300,160);
        pnlCom.setLocation(10, 60);
        add(pnlCom);
        GridBagLayout gb=new GridBagLayout();
        GridBagConstraints gc=new GridBagConstraints();
        pnlCom.setLayout(gb);

        jLabelcommPort = setJLabel("Com Port : ");
        jLabelbaudRate = setJLabel("Baud Rate : ");
        jLabelplcAddress = setJLabel("Plc Address : ");
        jLabelsendTime = setJLabel("Send Time : ");
        jLabelx50 = setJLabel(" x 50 ms (2 - 99)");
        jComboBoxcommPort = setJComboBox(commPortList);
        jComboBoxbaudRate = setJComboBox(bitRateList);
        jTextAreaPlcAddress = setJTextField("");
        jTextAreaSendTime = setJTextField("");

        gc.insets = new Insets(10,0,0,0);
        gc.ipadx = 120; 
        gc.weightx = 1;

问题是第一个面板（初始化为Cp，图片看起来不一样，标签移到左边，文本框又小又难看，这是不同的）。有人能帮忙吗，我对GridBagContsraints一点都不熟悉？

快速浏览一下，有问题的面板上的所有ipadx值声明都是作为注释进行的。看起来不错的面板没有。删除//标记并查看是否有帮助：）

通常，当我使用weightx或weighty时，我也使用填充约束：gc.fill=GridBagConstraint.Horizontal

例如，以下代码将使组件占用50%的可用水平空间

gc.weightx = 0.5;
gc.fill = GridBagConstraint.Horizontal;

实际上我不能测试你的代码，但是试试看，它会解决你的问题。您还应该尝试调用pack（）在父构造函数的末尾（我想是JFrame）。

谢谢您的快速回复。我试过了，在我把论坛（我试图改变面板的大小，我混合，但并没有thelp），标签再次在左边。如何在良好面板中定位标签？这是什么标签？谢谢你的快速回复。我试过了，在我把论坛（我试图改变面板的大小，我混合，但并没有thelp），标签再次在左边。如何在良好面板中定位标签？标签是什么？设置填充和设置重量。完全正确。设置填充，设置重量。确切地
