传入的是html代码,JEditorPane怎样显示网页?

[IEQQ]

已知JEditorPane.setPage(URL ); 可以显示一个网页.

如果传入的参数不是url 而是 "<font colro='#ff0000'>abc</font>",
怎样达到类似的效果?

谢谢先.

自己搞定了. 下面是方法.

方法一
這是比較基本的方法

JEditPane XD = new JEditPane();
XD.setEditorKit(new HTMLEditorKit());
XD.setText("<h1>zz</h1>");

[編輯]方法二
方法一最大的缺點在於說，如果你有一狗票的 html 內容，要這麼傻傻地用 setText() 的方式去輸入嗎？當然有別的方法。首先我們另外寫一個 html 檔，暫且稱之為「sample.html」，接著用 InputStreamer 去讀取它。

JEditPane XD = new JEditPane();
XD.setContentType("text/html");
HTMLEditorKit kit = new HTMLEditorKit();
XD.setEditorKit(kit);

HTMLDocument doc = (HTMLDocument)XD.getDocument();
File f = new File("sample.html");
try {
FileInputStream reader = new FileInputStream(f);
kit.read(reader,doc,0);
}catch(Exception e) {
e.printStackTrace();
}

应该说自己找到了, 其实还是人家帮忙搞定的.
