在JLabel中以不同方式对齐文本和图标

imageicon jlabel alignment swing java

BackSlash · 技术社区 · 13 年前

我试图创建一个文本向左对齐、图标向右对齐的JLabel,我尝试了以下代码:

_ip = new JLabel(ip);
_ip.setFont(boldFont);
_ip.setBounds(5, 0, 100, 50);
_ip.setIcon(images.ipBan);
_ip.setBorder(BorderFactory.createLineBorder(Color.black, 1));
_ip.setHorizontalTextPosition(SwingConstants.LEFT);
add(_ip);

这就是我得到的:

Alignment preview

红色的图像显示实际的图像对齐,灰色的图像显示我想要的图像所在的位置。

如果我加上

_ip.setAlignmentX(JLabel.RIGHT_ALIGNMENT);

什么都没发生,如果我加上

_ip.setHorizontalAlignment(JLabel.RIGHT);

图标向右对齐,但文本也向右对齐,我希望它向左对齐

有办法做到这一点吗?

或者,您可以使用 JPanel 具有合适的布局,如图所示 here .

enter image description here

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

public class CenteredJLabel {

    private JFrame frame = new JFrame("Test");
    private JPanel panel = new JPanel();
    private JLabel label = new JLabel("CenteredJLabel");
    private Icon errorIcon = UIManager.getIcon("OptionPane.errorIcon");

    public CenteredJLabel() {
        panel.setLayout(new GridBagLayout());
        panel.add(label);
        label.setHorizontalAlignment(SwingConstants.LEFT);
        label.setVerticalAlignment(SwingConstants.CENTER);
        label.setIcon(errorIcon);
        label.setIconTextGap(20);
        label.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
        panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.add(panel);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                CenteredJLabel centeredJLabel = new CenteredJLabel();
            }
        });
    }
}
