workflow::tree::sorter::sort_list_of_lists (public)

 workflow::tree::sorter::sort_list_of_lists -list list -sort_by sort_by \
    -object_id object_id -parent_object_id parent_object_id

Defined in packages/workflow/tcl/workflow-tree-procs.tcl

Sort the given list-of-lists. The list should have 3-4 columns:

• Display Name (should have any padding you want)
• Object ID
• Parent Object ID
• Object Name

The display name is the only column which is not critical for sorting the tree.

Example:

    # Get a list that can be used as the options of a 'select' widget in ad_form
    set directories [db_list_of_lists get_directories {
	select  lpad(' ', (level-1)*4*6 + 1, ' ') || directory_name as directory_name,
	                 directory_id,
	                 parent_directory_id,
	                 directory_name
	           from  directories
	         start   with parent_directory_id    is null
	         connect by prior directory_id       = parent_directory_id
    }]
     
    # Sort the options
    set directories [tree::sorter::sort_lists_of_lists -list $directories -sort_by 3 -object_id 1 -parent_object_id 2]
