Java 在JEditorPane/JTextArea上显示并附加图标，每个图标都显示在换行符中？

我正在尝试显示JEditorpane文件扩展名的系统图标，但只能显示最后一个图标？我想在换行符上追加并显示每个图标

String fileList[] = {".pdf", ".txt", ".doc", ".exe"}
JLabel label;
FileSystemView fsv = FileSystemView.getFileSystemView();
icon = fsv.getSystemIcon(File.createTempFile("file.", "." + filetype[i]));
label = new JLabel(icon);
StyleContext context = new StyleContext();
StyledDocument document = new DefaultStyledDocument(context);
Style labelStyle = context.getStyle(StyleContext.DEFAULT_STYLE);
StyleConstants.setComponent(labelStyle, label);
try {
    document.insertString(document.getLength(), "\n", labelStyle);
} catch (BadLocationException badLocationException) {
    System.err.println("Oops");
}
myjEditorPane.setDocument(document);

标签样式一次只能有一个图标的样式。将样式添加到文档时，不会保存样式

String fileList[] = {".pdf", ".txt", ".doc", ".exe"}
JLabel label;
FileSystemView fsv = FileSystemView.getFileSystemView();
icon = fsv.getSystemIcon(File.createTempFile("file.", "." + filetype[i]));
label = new JLabel(icon);
StyleContext context = new StyleContext();
StyledDocument document = new DefaultStyledDocument(context);
Style labelStyle = context.getStyle(StyleContext.DEFAULT_STYLE);
StyleConstants.setComponent(labelStyle, label);
try {
    document.insertString(document.getLength(), "\n", labelStyle);
} catch (BadLocationException badLocationException) {
    System.err.println("Oops");
}
myjEditorPane.setDocument(document);

如果要使用不同的图标，请使用：

String fileList[] = {".pdf", ".txt", ".doc", ".exe"}
JLabel label;
FileSystemView fsv = FileSystemView.getFileSystemView();
icon = fsv.getSystemIcon(File.createTempFile("file.", "." + filetype[i]));
label = new JLabel(icon);
StyleContext context = new StyleContext();
StyledDocument document = new DefaultStyledDocument(context);
Style labelStyle = context.getStyle(StyleContext.DEFAULT_STYLE);
StyleConstants.setComponent(labelStyle, label);
try {
    document.insertString(document.getLength(), "\n", labelStyle);
} catch (BadLocationException badLocationException) {
    System.err.println("Oops");
}
myjEditorPane.setDocument(document);

textPane.insertIcon(...);

在这种情况下，执行语句时会在文档中插入一个唯一的图标。

try{
String fileList[] = {".pdf", ".txt", ".doc", ".exe"}
JLabel label;
FileSystemView fsv = FileSystemView.getFileSystemView();
icon = fsv.getSystemIcon(File.createTempFile("file.", "." + filetype[i]));
label = new JLabel(icon);
StyleContext context = new StyleContext();
StyledDocument document = new DefaultStyledDocument(context);
Style labelStyle = context.getStyle(StyleContext.DEFAULT_STYLE);
StyleConstants.setComponent(labelStyle, label);
try {
    document.insertString(document.getLength(), "\n", labelStyle);
} catch (BadLocationException badLocationException) {
    System.err.println("Oops");
}
myjEditorPane.setDocument(document);

   try{

        StyledDocument doc = jTextPane1.getStyledDocument();
            Style def =  StyleContext.getDefaultStyleContext().getStyle(StyleContext.DEFAULT_STYLE );
        Style regular = doc.addStyle( "regular", def );
        Icon icon ;
        FileSystemView fsv = FileSystemView.getFileSystemView();
        for(int i=0;i<3;i++ ){
        icon = fsv.getSystemIcon(File.createTempFile("myfile.",".pdf"));
        jTextPane1.insertIcon(icon);
        doc.insertString( doc.getLength(),"pdfBook"+i+"\n", regular );
        }

  }catch(Exception excep){
         System.out.println("Exception");
      }

StyledDocument doc=jTextPane1.getStyledDocument（）；
Style def=StyleContext.getDefaultStyleContext（）.getStyle（StyleContext.DEFAULT_Style）；
常规样式=doc.addStyle（“常规”，def）；

FileSystemView fsv=FileSystemView.getFileSystemView（）；
