I haven't been paying attention to the whole thread but how bout this (from the
online help):
ALIGNMENT
This keyword applies to widgets created with the WIDGET_TABLE function.
Set this keyword equal to a scalar or 2-D array specifying the alignment of the
text within each cell. An alignment of 0 (the default) aligns the left edge of
the text with the left edge of the cell. An alignment of 2 right-justifies the
text, while 1 results in text centered within the cell. If ALIGNMENT is set
equal to a scalar, all table cells are aligned as specified. If ALIGNMENT is
set equal to a 2-D array, the alignment of each table cell is governed by the
corresponding element of the array. If the USE_TABLE_SELECT keyword is set,
then the alignment is changed only for the selected cells.

I hate to keep harping on this, but sometimes the simple
answers are the hardest to implement. :-)
I would send a book (of your choice and my modest means)
to anyone who can reliably center text in a text widget
using *any* kind of text. :-)
Cheers,
David

If you really want to do this, the answer is simple. Just don't use a
proportionally spaced font. You can set a font to Courier fairly easily at
least in IDL 5.1. Mainly, I had to get into this thread as I noticed that it
was the 'David' thread, and I wanted to add a David at the other end of the name...

Alas, this didn't work for me, given that my default font
is a proportionally spaced font. In fact, the text got cut
off. Apparently the character that is used to count "spaces"
is much smaller than the actual characters in my string.
In any case, I think centering text in a text widget is
probably impossible with proportionally spaced fonts.
Cheers,
David

David -
I'm procrastinating, so here's a little procedure to do this...
;=========================================================== =
; CENTER_TEXT.PRO 10-02-98 DSFoster
;
; Procedure to center a message within a text widget.
PRO center_text, text_wid, message
if (widget_info(text_wid, /valid_id) eq 0) then begin
message, 'Invalid widget identifier: ' + strmid(text_wid,2), /info
endif else if (widget_info(text_wid, /name) ne 'TEXT') then begin
message, 'Widget ID not a text widget: ' + strmid(text_wid,2), /info
endif else if (n_params() lt 2) then begin
message, 'Missing required parameters', /info
endif else begin
geom = widget_info(text_wid, /geometry)
xsize = round(geom.xsize) ; Size of text widget in chars
ok = execute( "str = string(' ', format='(a" + $
strtrim(xsize,2) + ")')" )
start = 0 > round((xsize - strlen(message))/2)
strput, str, message, start
widget_control, text_wid, set_value=str
endelse
return
END

Can't be done as far as I know. When I need centered text
I put the text in a Label Widget and use the Align_Center
keyword. :-)
Cheers,
David
