How to call wp_list_comments() with callback outside the loop

by

the template function as a callback argument of wp_list_comments function, and the template function takes three args:$comment, $args, $depth, like the template function that defined in the theme twentyeleven‘s functions.php,

function twentyeleven_comment( $comment, $args, $depth ) {
$GLOBALS['comment'] = $comment;
switch ( $comment->comment_type ) :
    case 'pingback' :
    case 'trackback' :
?>
<li class="post pingback">
    <p><?php _e( 'Pingback:', 'twentyeleven' ); ?> <?php comment_author_link(); ?><?php edit_comment_link( __( 'Edit', 'twentyeleven' ), '<span class="edit-link">', '</span>' ); ?></p>
<?php
     /** and more ... **/

I want to invoke this function in another place, and I have the $comment reference to a comment, but I don’t know how to set the $args and $depth variables. I know the value of $depth or $args can be changed in the admin settings, so, I can’t just set $depth to 5 or whatever a number.

How can I get the $args and $depth ???

Thanks in advance.

Just go ahead and call it in the same way the tventyeleven does:

<?php
                /* Loop through and list the comments. Tell wp_list_comments()
                 * to use twentyeleven_comment() to format the comments.
                 * If you want to overload this in a child theme then you can
                 * define twentyeleven_comment() and that will be used instead.
                 * See twentyeleven_comment() in twentyeleven/functions.php for more.
                 */
                wp_list_comments( array( 'callback' => 'twentyeleven_comment' ) );
            ?>

wp_list_comments function will manage $depth and other $args itself (in walker). See source code of wp_list_comments and the walker using callback arg
