有没有办法让多行 JLabel 文本围绕图标流动？

Question

目前在我的项目中我有多个 JLabel，每个都有自己的文本和图标

我的问题是图标占据了整个左侧

我想要达到的效果是让文字围绕图标流动

JLabel 可以实现这种效果吗？如果不能，是否可以使用任何其他组件？

Answer 1

如果这是一个 JLabel 而不是文本可编辑的 JTextArea，我会使用 HTMLed JLabel 而不是 JEditorPane。

public static void main(String[] args) throws Exception {
    String imageUrl = "https://d1nhio0ox7pgb.cloudfront.net/_img/g_collection_png/standard/512x512/person.png";
    Image sourceImage = ImageIO.read(new URI(imageUrl).toURL()).getScaledInstance(25, 25,
            Image.SCALE_SMOOTH);

    //Write the image to disk locally
    File fileWithImage = File.createTempFile("myicon", ".png");
    fileWithImage.deleteOnExit();

    ImageIO.write(toBufferedImage(sourceImage), "png", fileWithImage);

    String lorem = "Lorem Ipsum is simply dummy text of the printing<br>"
            + " and typesetting industry. Lorem Ipsum has been the industry's<br>"
            + " standard dummy text ever since the 1500s, when an unknown printer<br>"
            + " took a galley of type and scrambled it to make a type specimen book.<br>"
            + " It has survived not only five centuries, but also the leap into electronic<br>"
            + " typesetting, remaining essentially unchanged. It was popularised in the 1960s<br>"
            + " with the release of Letraset sheets containing Lorem Ipsum passages ";
    String imgTag = "<img src=\"" + fileWithImage.toURI() + "\">";

    final String htmlText = "<html>" + imgTag + " " + lorem;

    JOptionPane.showMessageDialog(null, new JLabel(htmlText));
}

public static BufferedImage toBufferedImage(Image img) {
    if (img instanceof BufferedImage) {
        return (BufferedImage) img;
    }

    BufferedImage bimage = new BufferedImage(img.getWidth(null), img.getHeight(null),
            BufferedImage.TYPE_INT_ARGB);
    Graphics2D bGr = bimage.createGraphics();
    bGr.drawImage(img, 0, 0, null);
    bGr.dispose();

    return bimage;
}

运行如上例。您将得到以下图像：

图像转换取决于您如何拥有图标，但想法是这样的。将图像写入临时文件，将其设为 URI，并将其作为 HTML 文本添加到标签中。

Answer 2

is it possible with any other component?

您可以使用 JTextPane.

它支持 insertIcon(...) 方法，允许您在文本中的任意位置插入图标。

您可以将文本窗格设置为不可编辑和透明，使其外观和行为更像 JLabel。

Is there a way to make multiline JLabel text flow around the icon?
