import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class GridBagLayoutExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("GridBagLayout Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel panel = new JPanel();
        panel.setLayout(new GridBagLayout());

        // 创建一个按钮并设置其大小
        JButton button = new JButton("Button");
        button.setSize(100, 50);

        // 创建一个GridBagConstraints对象，并设置fill属性为NONE
        GridBagConstraints constraints = new GridBagConstraints();
        constraints.fill = GridBagConstraints.NONE;

        // 将按钮添加到面板中，并应用GridBagConstraints
        panel.add(button, constraints);

        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
