Tools fixed-width printf() output on an XmList on Solaris

This one is a bit of bugger and I'm not sure if it's entirely relevant to this board but here goes...

I'm trying to produce some fixed width output to a List widget (X11/Motif GUI) So, I use something similar to:

sprintf(Buffer, "%*d%*f", 20, some_integer, 20, some_float);

This gives me a nice fixed-width string, which I then have to convert to an XmString and then add that to the List widget.

My problem is, after adding multiple lines, the columns are not aligned. On some machines they are (for instance if I remote shell from a Windows box using ReflectX), but on the host the output does not align.

Most of my widgets use the system default font, through which in Motif (as I understand it) you specify by using XmFONTLIST_DEFAULT_TAG in most of your XmString updates. I have a feeling that the font the host uses is not fixed-width - but I wouldn't have a clue where to change the font or what font it is using. Is it quite possible for X to use non fixed-width fonts?

Perhaps this is better targeted to a Motif forum, but thought it was worth a shot....

Thx in advance Smilie

NAME
xlsfonts - server font list displayer for X SYNOPSIS
xlsfonts [-display host:dpy] [-l] [-ll] [-lll] [-m] [-C] [-1] [-w width] [-n columns] [-u] [-o] [-fn pattern] DESCRIPTION
xlsfonts lists the fonts that match the given pattern. The wildcard character "*" may be used to match any sequence of characters (includ- ing none), and "?" to match any single character. If no pattern is given, "*" is assumed. The "*" and "?" characters must be quoted to prevent them from being expanded by the shell. OPTIONS
-display host:dpy This option specifies the X server to contact. -d host:dpy Same as -display host:dpy. -l Lists some attributes of the font on one line in addition to its name. -ll Lists font properties in addition to -l output. -lll Lists character metrics in addition to -ll output. -m This option indicates that long listings should also print the minimum and maximum bounds of each font. -C This option indicates that listings should use multiple columns. This is the same as -n 0. -1 This option indicates that listings should use a single column. This is the same as -n 1. -w width This option specifies the width in characters that should be used in figuring out how many columns to print. The default is 79. -n columns This option specifies the number of columns to use in displaying the output. By default, it will attempt to fit as many columns of font names into the number of character specified by -w width. -u This option indicates that the output should be left unsorted. -o This option indicates that xlsfonts should do an OpenFont (and QueryFont, if appropriate) rather than a ListFonts. This is useful if ListFonts or ListFontsWithInfo fail to list a known font (as is the case with some scaled font systems). -fn pattern This option specifies the font name pattern to match. SEE ALSO
X(7), Xserver(1), xset(1), xfd(1), X Logical Font Description Conventions ENVIRONMENT
DISPLAY DISPLAY must be set to get the default host and display to use. BUGS
Doing ``xlsfonts -l'' can tie up your server for a very long time. This is really a bug with single-threaded non-preemptable servers, not with this program. AUTHOR
