JTextPane：在底部插入文本

Question

我在JTextPane底部添加文本时遇到一些问题。在我做的所有研究中，我找到的唯一解决方案是将JTextPane添加到JPanel中。我的问题是我还有一个代码来包装文本行。文本换行和将JTextPane添加到JPanel中的组合不起作用。目前我的代码上有文本换行的东西，这里是：

package com.models;

import java.awt.Color;
import java.awt.Font;

import javax.swing.JTextPane;
import javax.swing.text.AbstractDocument;
import javax.swing.text.BadLocationException;
import javax.swing.text.BoxView;
import javax.swing.text.ComponentView;
import javax.swing.text.DefaultCaret;
import javax.swing.text.Element;
import javax.swing.text.IconView;
import javax.swing.text.LabelView;
import javax.swing.text.ParagraphView;
import javax.swing.text.Style;
import javax.swing.text.StyleConstants;
import javax.swing.text.StyledDocument;
import javax.swing.text.StyledEditorKit;
import javax.swing.text.View;
import javax.swing.text.ViewFactory;

import com.Config;

public class TextPane extends JTextPane
{
    private static final long serialVersionUID = -8251523472372069488L;

    private StyledDocument doc;
    private Style style;

    public TextPane()
    {
        DefaultCaret caret = (DefaultCaret) getCaret();
        caret.setUpdatePolicy(DefaultCaret.ALWAYS_UPDATE);

        setEditable(false);
        setFont(new Font("Lucida Console", Font.PLAIN, 12));
        setBackground(Color.LIGHT_GRAY);
        setCaret(caret);
        setEditorKit(new WrapEditorKit());

        doc = getStyledDocument();
        style = addStyle("Style", null);
    }

    public void append(Color color, String text)
    {
        StyleConstants.setForeground(style, color);

        try
        {
            doc.insertString(doc.getLength(), Config.LINE_SEPARATOR + text, style);
        }
        catch (BadLocationException e)
        {}
    }

    private class WrapEditorKit extends StyledEditorKit
    {
        private static final long serialVersionUID = -8173946569665645524L;

        final ViewFactory defaultFactory = new WrapColumnFactory();

        public ViewFactory getViewFactory()
        {
            return defaultFactory;
        }
    }

    private class WrapColumnFactory implements ViewFactory
    {
        public View create(Element elem)
        {
            final String kind = elem.getName();
            if (kind != null)
            {
                switch (kind)
                {
                case AbstractDocument.ContentElementName:
                    return new WrapLabelView(elem);
                case AbstractDocument.ParagraphElementName:
                    return new ParagraphView(elem);
                case AbstractDocument.SectionElementName:
                    return new BoxView(elem, View.Y_AXIS);
                case StyleConstants.ComponentElementName:
                    return new ComponentView(elem);
                case StyleConstants.IconElementName:
                    return new IconView(elem);
                default:
                    return new LabelView(elem);
                }
            }

            return new LabelView(elem);
        }
    }

    private class WrapLabelView extends LabelView
    {
        public WrapLabelView(Element elem)
        {
            super(elem);
        }

        public float getMinimumSpan(int axis)
        {
            switch (axis)
            {
            case View.X_AXIS:
                return 0;
            case View.Y_AXIS:
                return super.getMinimumSpan(axis);
            default:
                throw new IllegalArgumentException("Invalid axis: " + axis);
            }
        }
    }
}

我的问题是：如何进行文本换行并在JTextPane的底部插入文本
