I think I went on this same quest about a year ago and the answer is
no. If someone else knows better, please post your solution as I'm
sure a lot of people would like to know how to do this.
Perhaps (if applicable) there are some X-windows resources that could
be set to take care of this.
I believe your only solution is to use a column base and multiple
label widgets under that base. You can also use a text widget.
The downside of this is that certain widgets (widget_droplist and
widget_slider) and some compound widgets (i.e. cw_field) use the
title keyword. This is a single label and is already part of another
base. If one wants to have a multi-line title, the title keyword can't
be used, it has to be done as described above and (especially for
compound widgets) it may be hard to get the alignment that you desire.
It would be nice if the VALUE keyword to WIDGET_LABEL took a string
array and placed the strings in a column/row as specified by
ROW/COLUMN keywords to WIDGET_LABEL. On the other hand, it's not
too much of a problem to write a compound widget to do this.
I hope this helps.
