将HTML从JEditorPane复制到外部应用程序时出现问题 [英] Problem copying HTML from JEditorPane to external applications
问题描述
我无法将HTML从JEditorPane复制到系统剪贴板，然后再粘贴到其他应用程序中:
I'm having trouble copying HTML from JEditorPane to system clipboard and then pasting into other applications:
- OpenOffice 3.2-说请求的剪贴板格式不可用"
- 雷鸟3.13-在粘贴时不执行任何操作
- Firefox 3.6.9-接受纯文本，但是例如在GMail中，撰写邮件"在粘贴时不起作用
顺便说一句，我正在运行WinXP.在其他应用程序(如文本编辑器，MS Outlook，MS Word等)中，它可以按预期工作，即，根据应用程序需要的模仿类型，我得到带有HTML标签的纯文本或带格式的文本.
I'm running WinXP by the way. In other applications like text-editors, MS Outlook, MS Word etc. it works as expected, ie I get plain text with HTML tags stripped or formatted text according to which mimetype the application wants.
任何人都知道怎么了?在Swing或OpenOffice/Mozilla中有问题吗?
Anyone has an idea what's wrong? Is it a problem in Swing or in OpenOffice/Mozilla?
请参阅下面的测试应用程序并尝试.我也尝试过使用自定义的 Transferable ，但是一旦我为 DataFlavor 提供了mimetype ="text/html"，它就会在上述应用程序中停止工作.
See test application below and try out. I've also tried with a custom Transferable but as soon as I provide a DataFlavor with mimetype="text/html" it stops to work in applications mentioned above.

推荐答案
这很可能是接收方的问题. (因为我没有您的环境，所以我不能100％地确定.)
It's most likely a problem on the receiver end. (I can't be 100% sure since I don't have your environment.)
将Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();添加到按钮的actionPerformed中，我可以看到剪贴板具有正确的HTML内容:
Add Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard(); to your button's actionPerformed and I can see the clipboard has the right stuff with full html:
<html>
<head>
</head>
<body>
Here's some <b>formatted</b> <i>text</i>
</body>
</html>
正确粘贴到Word 2007中.
Pasting into Word 2007 works correctly.
