Question

我已经尝试了很多来创建以下布局，但我无法做到。我尝试使用各种约束，但我仍然无法做到。

我想要以下布局。

__________________________
| JLABEL          |  J   |
|_________________|  B   |
| JBUTTON         |  T   |
|_________________|__N___|

JBTN is JBUTTON.

我得到的结果是他们都只是在一条线上。或者有时候JBTN会出现在左下角，JLABEL＆amp; JBUTTON一行。

总的来说，我无法获得所需的布局。任何人都可以在这里帮忙或提供一些建议如何解决它？

这看起来像你想要的布局：

import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JLabel;
import javax.swing.JButton;
import java.awt.GridBagLayout;
import java.awt.GridBagConstraints;
import java.awt.Insets;

public class Answer extends JFrame {

    private JPanel contentPane;

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

    /**
     * Create the frame.
     */
    public Answer() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        GridBagLayout gbl_contentPane = new GridBagLayout();
        gbl_contentPane.columnWidths = new int[]{302, 89, 0};
        gbl_contentPane.rowHeights = new int[]{115, 128, 0};
        gbl_contentPane.columnWeights = new double[]{0.0, 0.0, Double.MIN_VALUE};
        gbl_contentPane.rowWeights = new double[]{0.0, 0.0, Double.MIN_VALUE};
        contentPane.setLayout(gbl_contentPane);

        JLabel lblNewLabel = new JLabel("New label");
        GridBagConstraints gbc_lblNewLabel = new GridBagConstraints();
        gbc_lblNewLabel.fill = GridBagConstraints.BOTH;
        gbc_lblNewLabel.insets = new Insets(0, 0, 5, 5);
        gbc_lblNewLabel.gridx = 0;
        gbc_lblNewLabel.gridy = 0;
        contentPane.add(lblNewLabel, gbc_lblNewLabel);

        JButton btnNewButton = new JButton("New button");
        GridBagConstraints gbc_btnNewButton = new GridBagConstraints();
        gbc_btnNewButton.anchor = GridBagConstraints.WEST;
        gbc_btnNewButton.fill = GridBagConstraints.VERTICAL;
        gbc_btnNewButton.gridheight = 2;
        gbc_btnNewButton.gridx = 1;
        gbc_btnNewButton.gridy = 0;
        contentPane.add(btnNewButton, gbc_btnNewButton);

        JButton btnNewButton_1 = new JButton("New button");
        GridBagConstraints gbc_btnNewButton_1 = new GridBagConstraints();
        gbc_btnNewButton_1.fill = GridBagConstraints.BOTH;
        gbc_btnNewButton_1.insets = new Insets(0, 0, 0, 5);
        gbc_btnNewButton_1.gridx = 0;
        gbc_btnNewButton_1.gridy = 1;
        contentPane.add(btnNewButton_1, gbc_btnNewButton_1);
    }

}

如何使用GridBagConstraints创建这种类型的布局？
