java - 如何使图标和文本在 JButton 上对齐左侧

Question

我只想让文本和图标对齐提升侧这是代码

import java.awt.Dimension;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class LeftSide
{
public LeftSide()
{
JFrame frame = new JFrame("Button");
JPanel panel = new JPanel();
JButton button = new JButton("Submit");
button.setPreferredSize(new Dimension(200, 30));
button.setIcon(new ImageIcon(this.getClass().getResource("submit.gif")));
panel.add(button);
frame.add(panel);
frame.setVisible(true);
}

public static void main(String[] args)
{
new LeftSide();
}

如果我运行此代码，我将在按钮中心的按钮上获得图标和文本，因此如何将它们置于左侧；

要将文本左对齐，请使用 button.setHorizo​​ntalAlignment(SwingConstants.LEFT);

import java.awt.Dimension;
import javax.swing.*;

public class LeftSide
{
    public LeftSide()
    {
        JFrame frame = new JFrame("Button");
        JPanel panel = new JPanel();
        JButton button = new JButton("Submit");
        button.setPreferredSize(new Dimension(200, 30));
        button.setIcon(new ImageIcon(this.getClass().getResource("submit.gif")));
        button.setHorizontalAlignment(SwingConstants.LEFT);
        panel.add(button);
        frame.add(panel);
        frame.setVisible(true);
    }

    public static void main(String[] args)
    {
        new LeftSide();
    }
}
