Change background of a specific line of JTextArea

Question

Is there any way to change the background of a specific line of JTextArea?

I see this post, but I would like to change the color of the entire line and not only where there is text (like eclipse editor) — pedrohreis, Feb 19 '15 at 22:29

@AndrewThompson, how does selecting it help? It only highlights the text, not the entire line. — camickr, Feb 20 '15 at 01:29

Really, what's wrong with a `Highlighter`? – MadProgrammer Feb 19 '15 at 23:18
@MadProgrammer, the default HIghlighter doesn't paint the entire line, unless you use the `setDrawsLayeredHighlights(false)` property of the Highlighter. This would probably be the solution for static highlighting. If you want dynamic highlighting based on the caret location you can use the LinePainter. – camickr Feb 20 '15 at 01:24
@camickr Still scratching my head over the requirements :P – MadProgrammer Feb 20 '15 at 01:28

@MadProgrammer, the requirement is to highlight the background of the entire line, not just the background of the text. – camickr Feb 20 '15 at 01:33
@camickr *"background of a specific line"* - Is open to interruption ;) – MadProgrammer Feb 20 '15 at 01:38
@camickr get the idea, I wanted highlight the background of the entire line. Maybe I didn't express myself very well. – pedrohreis Feb 20 '15 at 03:05
