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

xmcreatescrolledlist

XmCreateScrolledList(library call)										XmCreateScrolledList(library call)

NAME

       XmCreateScrolledList -- The List ScrolledList convenience creation function

SYNOPSIS

       #include <Xm/List.h>
       Widget XmCreateScrolledList(
       Widget parent,
       String name,
       ArgList arglist,
       Cardinal argcount);

DESCRIPTION

       XmCreateScrolledList  creates an instance of a List widget that is contained within a ScrolledWindow.  The ScrolledWindow parent is created
       managed.  All ScrolledWindow subarea widgets are automatically created by this function.  The ID returned by this function is that  of  the
       List widget (not the ScrolledWindow widget).  Use this widget ID for all operations on the List widget.	Use the widget ID of the List wid-
       get's parent for all operations on the ScrolledWindow.  To obtain the ID of the ScrolledWindow widget associated with the List widget,  use
       the Xt Intrinsics XtParent function.  The name of the ScrolledWindow created by this function is formed by concatenating SW onto the end of
       the name specified in the parameter list.

       All arguments to either the List or the ScrolledWindow widget can be specified at creation time using this function.   Changes  to  initial
       position  and size are sent only to the ScrolledWindow widget.  Other resources are sent to the List or the ScrolledWindow widget as appro-
       priate.	Note that the result of providing the XmNdestroyCallback resource in the creation arglist is unspecified. The  application  should
       use the XtAddCallback function to add callbacks to the appropriate widget (List or ScrolledWindow) after creating it.

       This function forces the following initial values for ScrolledWindow resources:

	  o  XmNscrollingPolicy is set to XmAPPLICATION_DEFINED.

	  o  XmNvisualPolicy is set to XmVARIABLE.

	  o  XmNscrollBarDisplayPolicy is set to XmSTATIC.  (No initial value is forced for the List's XmNscrollBarDisplayPolicy.)

	  o  XmNshadowThickness is set to 0 (zero).

       parent	 Specifies the parent widget ID

       name	 Specifies the name of the created widget

       arglist	 Specifies the argument list

       argcount  Specifies the number of attribute/value pairs in the argument list (arglist)

       For a complete definition of List and its associated resources, see XmList(3).

RETURN

       Returns the List widget ID.
