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.

I'm using a JTextPane to edit HTML. When I enter newlines in the GUI component and call getText() on the JTextPane, I get a string with newline characters.

I'm trying to create a simple WYSIWYG editor that will allow users to select text and bold/underline/italicise it. Currently the user can select text, right-click it and select bold from a popup menu, which ends up applying the bold style to the selected text like so: this.getStyledDocument().setCharacterAttributes(this.getSelectionStar...
