How can I sort nodes of a CL_GUI_SIMPLE_TREE tree?

[Former Member]

Hi,

after a lot of unsatisfying searching I´ll take the chance to open a new thread. I have already implemented a tree by using the CL_GUI_SIMPLE_TREE class. The main nodes of the tree represent material-numbers.

Every material-number has some sub-nodes. My concern is to sort the main nodes ascending. But how can I realize that.

- Material1

|-Subkategorie1

|-Subkategorie2

- Material2

...

I hope i described my problem understandable enought. If anyone has an idea please let me know.

Thanks a lot

Check this sample code

  create object g_tree
    exporting
      parent              = g_custom_container
      node_selection_mode = cl_gui_simple_tree=>node_sel_mode_single
    exceptions
      lifetime_error              = 1
      cntl_system_error           = 2
      create_error                = 3
      failed                      = 4
      illegal_node_selection_mode = 5.
  if sy-subrc <> 0.
    message a000.
  endif.

* define the events which will be passed to the backend
  ....
  ....
  ....
  call method g_tree->set_registered_events
  ....
  ....

* assign event handlers in the application class to each desired event
  set handler g_application->handle_node_double_click for g_tree.


* Sort Nodes

  sort g_prog_table by komp_name.

  node-node_key = 'Root'.              

  clear node-relatkey.      " Special case: A root node has no parent
  clear node-relatship.                " node.

  node-hidden = ' '.                   " The node is visible,
  node-disabled = ' '.                 " selectable,
  node-isfolder = 'X'.                 " a folder.
  clear node-n_image.       " Folder-/ Leaf-Symbol in state "closed":
                                       " use default.
  clear node-exp_image.     " Folder-/ Leaf-Symbol in state "open":
                                       " use default
  clear node-expander.                 " see below.
  node-text = text-001.
  append node to g_node_table.

  loop at g_prog_table into g_wa_prog_table.

*   Insert nodes
    clear node.
    node-node_key = g_wa_prog_table-key.
    node-relatkey = 'Root'.
    node-relatship = cl_gui_simple_tree=>relat_last_child.
    node-n_image = '@GV@'.
    node-expander = ' '.
    node-text = g_wa_prog_table-komp_name.
    append node to node_table.

  endloop.
