You can't use the graphics systems with WIDGET_TEXT. I can think of
two alternatives (not for the faint of heart):

  * create a WIDGET_DRAW instead of a WIDGET_TEXT and output your text
into it. If this is the main editing window of your text editor, good
luck. But for a label or single line somewhere it is not too bad.
There are keywords to WIDGET_INFO to get the right background color,
font, width of a given string in pixels, etc.

  * if on Unix, use Xdefaults.

I don't see any reasonable "IDL only" solutions if you are trying to
chromo-code the code in your macro language text editor. Maybe there's
something you could use with WIDGET_ACTIVEX if you are on Windows?
