Is there a way of setting the selection of a file browser widget from
my program?  On module initialization, I want to set the directory to
the current working directory.  I have tried this code:

store_frames_init ()
        {
        char curr_dir[256];

        if ( getcwd (curr_dir, 256) == NULL)
                {
                return -1;
                }

        strcat (curr_dir, "/*");

        cxInWdgtStrSet ("Frame File", curr_dir);

        return 0;
        }       /* end of store_frames_init */


(Where "Frame File" is the name of the input port assiated with the
file browser.)

I find that this code properly sets the "Selection" string and
the "Contents" window shows the contents of the current directory,
but the directory menu is not updated to show the current 
directory.

Is this a bug in cxInWdgtStrSet, or should I not be trying to use
it for this purpose?  Is there another way to achieve this?

Thanks.

: 
:         strcat (curr_dir, "/*");

I think the problem is adding the * to the end of the directory.  The
explorer widget doesn't know how to deal with the wildcard.  I have
successfully set the directory by using "./".

Hope this helps,

Jim
