按钮单击应调用选项卡窗格（动态），其中包含文本面板

Question

我正在寻找一个例子，点击不同的按钮时应打开不同的标签，结果/输出应写入其中的文本面板。

文本面板应嵌入选项卡内。

我正在寻找示例而不是完整的解决方案

您应该在按钮侦听器中调用JTabbedPane.setSelectedIndex，请尝试以下示例：

import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTabbedPane;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

public class Main
{
    private static int numberOfTabs = 1;

    public static void main(String[] args)
    {
        SwingUtilities.invokeLater(new Runnable()
        {
            public void run()
            {
                try
                {
                    UIManager.setLookAndFeel(
                            "javax.swing.plaf.nimbus.NimbusLookAndFeel");
                }
                catch (ClassNotFoundException | InstantiationException
                        | IllegalAccessException
                        | UnsupportedLookAndFeelException e)
                {
                }
                JFrame frame = new JFrame();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setBounds(100, 100, 400, 500);

                JButton addNewTab = new JButton("Add new Tab");

                JTabbedPane tab = new JTabbedPane();

                addNewTab.addActionListener(e -> {
                    tab.add(new JLabel("new tab " + numberOfTabs + " created."),
                            "tab " + numberOfTabs);
                    tab.setSelectedIndex(numberOfTabs - 1);
                    numberOfTabs++;
                });
                frame.add(addNewTab, BorderLayout.NORTH);

                frame.add(tab, BorderLayout.CENTER);
                frame.setVisible(true);
            }
        });
    }
}
