JEditorPane可以显示网页，图像等
他的子类JTextPane功能更强大

jacob can be used to access activex

awt中用TextArea
swing中用JTextArea

javax.swing.JTextPane
JTextPane是swing文本组件的卡迪拉克:)
---摘自java2 图形设计卷II Swing技术 p939

各位大狭您们说的都有道理，但是我最需要的是能够控制单个字符的颜色
如果abcd，如何控制a为黑色，b为红色，c为绿色d为蓝色等。请各们帮忙，告诉我属性，如果100分不够，我在另开帖子送分。
急呀，在线等待
！！！

比較簡單的方法是將單個字符都用jlabel來顯示~~~

將單個字符都用jlabel來顯示,非累死不可，来坐上swing文本组件的卡迪拉克
兜兜风吧
