How do I easily edit the style of the selected text in a JTextPane? There doesn't seem to be many resources on this. Even if you can direct me to a good resource on this, I'd greatly appreciate it.

此外，如何获取所选文本的当前样式?我尝试了styledDoc.getLogicalStyle(textPane.getSelectionStart());，但似乎没有用.

Also, how do I get the current style of the selected text? I tried styledDoc.getLogicalStyle(textPane.getSelectionStart()); but it doesn't seem to be working.

推荐答案

在此pastebin中查看以下代码:

示例从这里:

您似乎可以在动作侦听器中使用以下命令来更改样式:

It looks like you can change the style using the following in an action listener:

final Style boldStyle = sc.addStyle("MainStyle", defaultStyle);
StyleConstants.setBold(boldStyle, true);   

doc.setCharacterAttributes(0, 10, boldStyle, true);

它将给定的偏移量和长度之间的文本样式设置为特定样式.

It sets the style of the text between the given offset and length to a specific style.

有关更多详细信息，请参见完整的pastebin.那样应该可以解决您的问题.

See the full pastebin for more details. That should fix your problem though.
