Java JTextPane更改所选文本的字体

Question

I have a JTextPane (or JEditorPane, I can use either no problem). How can I change the font of a selected area to a specific font?

textpane.getSelectedText().setFont() won't work. (Even with font-family)

Answer 1

You can change JTextPane's font only as a whole, it doesn't do rich text.

There's a Document underneath JEditorPane (and apparently JTextPane too), which you get a hold of with getDocument() . You want to cast that to a StyledDocument if you can, and then you can do things like setCharacterAttributes to a given run of characters.

There are some (hopefully) helpful examples in the Java tutorial at http://java.sun.com/docs/books/tutorial/uiswing/components/editorpane.html .

Answer 2

You can do this by using JTextPane. It is impossible to do this using JTextArea. . Here is a best example on how to use JTextPane.
