如何在Jpanel中的JLabel旁边添加JSeparator？

Question

如何使用JPanel在MigLayout中添加所有这些组件，并实现上图所述的其他条件？

Answer 1

使用MigLayout，您只需向相邻的单元格添加JSeparator，即可为其提供growx属性。例如：

JLabel lblPersonal = new JLabel("Personal");
contentPane.add(lblPersonal, "cell 0 0");
contentPane.add(new JSeparator(), "cell 1 0,growx");

或者，也许更好的方法是在面板上使用边框，同时为面板提供标题：

import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
import net.miginfocom.swing.MigLayout;

public class TitledPanel extends JFrame {
    private static final long serialVersionUID = 1L;
    private JPanel contentPane;
    private JTextField textField;

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    TitledPanel frame = new TitledPanel();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    public TitledPanel() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(new MigLayout("", "[grow]", "[grow]"));

        JPanel panel = new JPanel();
        panel.setBorder(new TitledBorder(BorderFactory.createLineBorder(Color.LIGHT_GRAY), "Personal"));
        contentPane.add(panel, "cell 0 0,grow");

        JLabel lblLabel = new JLabel("Label 1");
        panel.add(lblLabel);

        textField = new JTextField();
        panel.add(textField);
        textField.setColumns(10);

        pack();
    }

}

现在，如果要在传递字符串参数时创建一个返回此类面板的函数，可以扩展JPanel或创建自己的类，返回自定义创建的JPanel给出标题标签和分隔符。
