其他操作如下：

1、对字体的操作

    MutableAttributeSet attr = new SimpleAttributeSet();
    StyleConstants.setFontFamily(attr, family);
    setCharacterAttributes(editor, attr, false);

family为字体

2、对字体大小的操作

    MutableAttributeSet attr = new SimpleAttributeSet();
    StyleConstants.setFontSize(attr, size);
    setCharacterAttributes(editor, attr, false);

size为字号

3、是否是粗体的操作

   StyledEditorKit kit = getStyledEditorKit(editor);
   MutableAttributeSet attr = kit.getInputAttributes();
   boolean bold = (StyleConstants.isBold(attr)) ? false : true;
   SimpleAttributeSet sas = new SimpleAttributeSet();
   StyleConstants.setBold(sas, bold);
   setCharacterAttributes(editor, sas, false);

4、是否是斜体的操作

   StyledEditorKit kit = getStyledEditorKit(editor);
   MutableAttributeSet attr = kit.getInputAttributes();
   boolean italic = (StyleConstants.isItalic(attr)) ? false : true;
   SimpleAttributeSet sas = new SimpleAttributeSet();
   StyleConstants.setItalic(sas, italic);
   setCharacterAttributes(editor, sas, false);

5、是否有下划线的操作

   StyledEditorKit kit = getStyledEditorKit(editor);
   MutableAttributeSet attr = kit.getInputAttributes();
   boolean underline = (StyleConstants.isUnderline(attr)) ? false: true;
   SimpleAttributeSet sas = new SimpleAttributeSet();
   StyleConstants.setUnderline(sas, underline);
   setCharacterAttributes(editor, sas, false);

6、左中右对齐的处理

   MutableAttributeSet attr = new SimpleAttributeSet();
   StyleConstants.setAlignment(attr, a);
   setParagraphAttributes(editor, attr, false);
public static final void setParagraphAttributes(JEditorPane editor,
  AttributeSet attr, boolean replace) {
  int p0 = editor.getSelectionStart();
  int p1 = editor.getSelectionEnd();
  StyledDocument doc = getStyledDocument(editor);
  doc.setParagraphAttributes(p0, p1 - p0, attr, replace);
}

a:0：左，1：中，2：右

7、文本字体颜色的设置

    MutableAttributeSet attr = new SimpleAttributeSet();
    StyleConstants.setForeground(attr, fg);
    setCharacterAttributes(editor, attr, false);

fg：为color

8、文本背景颜色的设置

    MutableAttributeSet attr = new SimpleAttributeSet();
    StyleConstants.setBackground(attr, bg);
    setCharacterAttributes(editor, attr, false);
