Allowing different styles in JAVA to work per line and per users choice

Allowing different styles in JAVA to work per line and per users choice

I run an online game that has been around for a while and I am doing some
revamping to the cosmetics to add some more functionality to the chat
area. I would like people when they click, Plain, Bold or Italic for the
game to update their individual line with their prefered Font.STYLE. Like
they do on those fancy Java based chat applications.
How would I set it to work like I want it to? via the "PrintLine" or
"TextArea"
This is my current code.
