As I've almost finished term for my 6 week Christmas holiday (life's so
hard) then I would have been happy to give this a go. There is one major
problem which will stop it from working however. You can't create table
widgets that don't have scroll bars and so you can't create a single
standalone cell, which could look like a CW_Field. Try this code to see what
I mean:
base = Widget_Base()
table = Widget_Table(base, XSIZE=1, YSIZE=1, VALUE=[0], ROW_LABELS=[' '],
COLUMN_LABELS=[' '], SCROLL=0)
Widget_Control, base, /REALIZE
See what I mean - it just looks messy. Well it does on windows, at least,
I'm not sure about UNIX. So I', afraid this idea's a bit of a non starter (I
think).

Humm. Maybe if you have a non-proportionally spaced
font in the text widget, but I doubt otherwise. A
table widget allows you to justify text. Maybe
Phil Aldis will write us a nice CW_FIELD-like compound
widget object that uses a Table Widget rather than a text
widget. :-)
Cheers,
David

If you set the size of the text area explicitly, you
could do something like this:
xsize = 40
ysize = 1
base = WIDGET_BASE (/COLUMN)
text = WIDGET_TEXT (base, XSIZE = xsize, YSIZE = ysize, VALUE = '')
WIDGET_CONTROL, /REALIZE, base
num = 10.00
fmt = "(F" + STRTRIM (xsize, 2) + ".2)" ; F40.2
str = STRING (num, FORMAT = fmt)
WIDGET_CONTROL, text, SET_VALUE = str
You could make the number of digits after the decimal point a
parameter as well; here I just hardcoded it to 2.
