    I'm looking for a little help with scrolling lists under OpenWindows 
(XView).  I'm using DevGuide to generate C code stubs of scrolling lists, 
I'm having trouble getting the information into the lists.

    Volume Seven of the XView Programming Manual gives two examples of how
to hard code these choices into the code on pages 155 and 157.  As shown
below:

    xv_create(panel, PANEL_LIST, 
	PANEL_LIST_STRINGS,  "One", "Two", "Three", NULL,
	NULL);

	This is fine if you know what you want in the list ahead of time, but
what if you want to read in a list of files from a directory?  I figured I
could just substitute a pointer to an array of strings in place of the
strings themselves as shown below:

    static char	*mylist[3] = { "One", "Two", "Three" };

    xv_create(panel, PANEL_LIST, 
	PANEL_LIST_STRINGS,  *mylist, NULL,
	NULL);

	This will give me the first string in the list, but not the rest.
And if I tack the NULL onto the list itself and remove it from after *mylist,
I get a segmentation fault and a core in my lap.

	If anyone out there has worked on this, Please, Please send me some
e-mail with an explaination of how you did this.  I'd really appreciate it.

	Thanks again,
				Steve.
