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

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

XmListPosToBounds(library call) XmListPosToBounds(library call) NAME
XmListPosToBounds -- A List function that returns the bounding box of an item at a specified position in a list SYNOPSIS
#include <Xm/List.h> Boolean XmListPosToBounds( Widget widget, int position, Position *x, Position *y, Dimension *width, Dimension *height); DESCRIPTION
XmListPosToBounds returns the coordinates of an item within a list and the dimensions of its bounding box. The function returns the associ- ated x and y-coordinates of the upper left corner of the bounding box relative to the upper left corner of the List widget, as well as the width and the height of the box. The caller can pass a NULL value for the x, y, width, or height parameters to indicate that the return value for that parameter is not requested. widget Specifies the ID of the List widget. position Specifies the position of the specified item. A value of 1 indicates the first item in the list; a value of 2 indicates the sec- ond item; and so on. A value of 0 (zero) specifies the last item in the list. x Specifies a pointer to the returned x-coordinate of the item. y Specifies the pointer to the returned y-coordinate of the item. width Specifies the pointer to the returned width of the item. height Specifies the pointer to the returned height of the item. For a complete definition of List and its associated resources, see XmList(3). RETURN
If the item at the specified position is not visible, returns False, and the returned values (if any) are undefined. Otherwise, this func- tion returns True. RELATED
