我已经使用 JTextPane 和 AdvancedRTFEditorKit 在 java/swing 中创建了一个编辑器，我从这里找到了它（使用它而不是 RTFEditorKit，因为它已经过时了），但是如果你可以说这是一个问题，我有一个“问题” ，使用 AdvancedRTFEditorKit 我只能打开我用它创建的文件，例如我无法打开 .txt、.java、.cpp、.c，我只能打开我使用编辑器创建的文件。所以是正常吗？或者我做错了什么？还有其他人使用 AdvancedRTFEditorKit 吗？
谢谢大家，很高兴很快看到答案！
我用过这个 RTF 编辑器工具包：点击这里！
这是SSCCE...
