How to draw line in JTextArea and change color of a specific words

Question

I'm currently developing JTextArea with a Notepad++ like function (currently indentation function finished).

Now I'm trying to add a function which in my JTextArea will show a dotted line for an indentation with same level, and change specific color of a word.

Thanks in advance :)

Answer 1

You will not able to achieve your target with JTextArea as it is a plain text support component.You have to use a Styled text supported JEditorPane or JTextPane.And try to use a HTML document and achieve it.Look at
