I have displayed multi-line text in the WIDGET_TEXT using special
characters and/or creating a text array. I find it's important that the
XSIZE and YSIZE are set. See sample IDL code below.
Wish we could do color in the WIDGET_TEXT, but I haven't seen how,
yet.

Hello,
A couple of thoughts to share...
(1) You can specify the VALUE of the text widget as an array - the array
should appear on screen with one line per array element.
(2) If you want to append text string(s) to the the text already shown
you can use the APPEND keyword when using WIDGET_CONTROL to set the
VALUE. I use this in some applications with a scrolling text widget to
show a save-able output log.
Cheers,
Ben

Thanks, Jeff, for the answer, but this doesn't work, the text appears
simply as This!CText

If you want the string "This Text" to show up as
This
Text
I think you need to use "This!CText". I think that's right anyway, I'm
going from memory here.
