ALV TREE add node

can someone please help me ?
I can't find how the method add_node for a alv tree works:
CALL METHOD tree->add_node
    EXPORTING
      i_relat_node_key =
      i_relationship   =
      i_node_text      =
      is_outtab_line   =
    IMPORTING
      e_new_node_key   =
can someone please explain me the meaning of the parameters?
thanks in advance

Hi Gabriele,
Check out the below sample code to use of the method add_node.
data: l_relat_node_key type lvc_nkey,
         l_node_text type lvc_value,
         ls_node_layout type lvc_s_layn,
         ls_node_key like node_key,
         new_node_key type lvc_nkey.
    call method alv_tree_control->add_node
      exporting i_relat_node_key = l_relat_node_key
                i_relationship   = cl_gui_column_tree=>relat_last_child
                i_node_text      = l_node_text
                is_node_layout   = ls_node_layout
                is_outtab_line   = ls_tree
      importing e_new_node_key   = new_node_key.
*   ID und Node_key in Tabelle gt_node_key abspeichern
    ls_node_key-id       = ls_tree-klnodetext-id.
    ls_node_key-node_key = new_node_key.
    append ls_node_key to l_node_key_tbl.
This might helpful for you.
Thanks,
Chidanand

ALV tree - change node text

hello,
on a screen I have input fields such as year and below a container holding an ALV tree.
When I change the year value, that starts a new selection from a table and should result in changing many of the lines in the tree.
I was trying to use the methods "get_outtab_line" to retrieve the tree line data and then changing this data with method "change_node".
The problem is I cannot access the correct node-key. The node-key value is kept in memory somewhere and when I refresh the alv tree at PBO, the node-key is incremented from the stored value which means I cannot use get_outtab_line properly.
Any suggestions or example programs,
Thanks a lot,
Kevin

Hi Kevin,
Try using method update_calculations instead of directly using frontend_update.
So the sequence should be,
IF NOT ref_tree IS INITIAL.
CALL METHOD ref_tree->free.
ENDIF.
CREATE OBJECT ref_tree...
CALL METHOD ref_tree->set_table_for_first_display...
****Data fill in a loop
CALL METHOD ref_tree->add_node..
****Expand if needed
CALL METHOD ref_tree->expand_node..
****Toolbar Logic if needed..
****Events Registration
****Finally call to update calculations
CALL METHOD ref_tree->update_calculations..
Hope this helps..

Editing of a Column of ALV Tree(OOPS) node

is it possible to edit a column of node of ALV tree.
i am using ALV class "CL_GUI_ALV_TREE".
After searching existing threads, for the same issue..i found the following.
1) Editable Tree ALV
( displays pop up window where user can change values and then transfer these changes back to ALV tree)
2) Editable Field in ALV TREE Display Using OOPs
(this approach is not working for ALV Tree)
But i want to edit directly coulmn of a node of ALV tree.
is it possible in OOPS ALV Tree?
if it possible, can any one provide the sample code,

As you already noticed, this is not possible, but you may edit your fields outside the tree and bring your changes back to tree. I struggled with the same once but eventually used described alternative. If you use saplink you may check upgrade [chain and rename|http://code.google.com/p/saplink-chain-and-rename/downloads/list] where this approach is released. The code is free so you will be able to study and copy whatever you need from it.
Editing in a pop up is also an alternative here.

ALV Tree, Expanded node do not show data in certain column

Hi all,
I need your help regard to below problem.
I have an ALV grid in which one of the columns has F4 (search help). If search help is called by pressing a F4 button a dialog box will be shown with ALV tree on it.
The ALV Tree has 2 columns which are: hierarchy column and one other column called WBS column. At the first show, all expanded node show data contained in WBS column, but if I click to expand a collapsed node, data is not shown in WBS column for the new expanded rows, only shows data in hierarchy column. How to show data in WBS column for the new expanded rows..?
Basically if at the first show I expand all node, data in WBS column are shown for all rows. It seems that the Expand Node event doesn't update all column data to be shown.
Please share if anyone of you has faced this kind of problem. Thank you.

Ramses Hutahaean

Hi Fenja,
as the click-events only raise the node_key (at least I couldn't detect another information), I assume the only way is maintaining an internal helper table by yourself which you build up in parallel when creating the tree and its nodes.
The (hashed) table might contain 2 columns:
1. node_key (as table key)
2. reference to an object
When a click-event is raised, you look up the corresponding object reference in your table.

Drag and Drop between two ALV Tree.

Hi,
I am trying the drag and drop event between two ALV Tree.
After the occurence of drag and drop event , I am able to get the node key of the source tree node which is dragged . But when the node is dropped onto the target ALV Tree the target node does not gets selected, instead a plus mark appears focussing on the target node in the target ALV Tree. Can anyone suggest a way to get the node key of the focussed target node. Thanks.

Quick Info on ALV Tree node

Hi All,
I have this requirement.
On ALV Tree node, when user places cursor then i should display some text as quick info.
while create node i have used ICON <- left arrow, i cannot use other ICOn as functional person need this icon only.
During Add_Node, if I pass icon through node layout then its showing nothing, Instead if I pass icon through item layout, then its showing SAP standard ICON text left arrow , but i need custom text write text there.
I tried using Context_menu_req as well, even that didnt worked. Any ideas/views will be highly appreciated.
Thanks n Regards

Hi Mr A.
You can try the following:
DATA: l_node_text TYPE lvc_value.
DATA: ls_item_layo TYPE lvc_s_layi,
             lt_item_layo TYPE lvc_t_layi.
        l_node_text             = 'UR Text'
        ls_item_layo-style      = gs_detail-color_code.
        ls_item_layo-t_image    = gs_detail-icon.
        APPEND ls_item_layo TO lt_item_layo.
After the above mentioned statement, you may call 'Add Node' method of ALV Tree.

and set_techno is fk
and use
following code for view my tree:

Get Node Key Multiple Items Selected from ALV tree

Hello Experts,
I'm having a problem in getting Node keys for the items displayed as ALV tree.
I'm able to get Node key, when only ONE record (Item) is selected.
But, when I select multiple items under a Single node am not able to read(get) the node keys for all the selected items.
I'm using the classCL_GUI_ALV_TREE.
I have tried using the method GET_CHECKED_ITEMS, but not getting the keys.
method GET_SELECTED_ITEM is giving node for a single item. I need it for multiple items selected.
Thank you for your time.

Hi,
You need to use checkbox concept. and use method GET_CHECKED_ITEMS get selected items

Macking button to expand the tree and collapse tree and another to add node

macking button to expand the tree and collapse tree and another to add node and saving the changes in the database ( this is problem)
and finally delete node from database
so what is proper code for those buttons
thanks my mail is :

Hello,
Use the ftree package's functions
code to expand all nodes:
PROCEDURE explose_tree IS
node    ftree.node;
htree   ITEM;
state   varchar2(30);
BEGIN
   -- search the tree ID --
   htree := Find_Item('BL_TREE.TREE_1');
    -- search the root --
     node := Ftree.Find_Tree_Node(htree, '');
    -- expand all nodes --
   WHILE NOT Ftree.ID_NULL(node) LOOP
      state := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_STATE);
      IF state = Ftree.COLLAPSED_NODE THEN
        Ftree.Set_Tree_Node_Property(htree, node, Ftree.NODE_STATE, Ftree.EXPANDED_NODE);
      END IF;
      node := Ftree.Find_Tree_Node(htree, '', ftree.find_NEXT,Ftree.NODE_LABEL,'', node);
   END LOOP;
END;and to collapse all nodes:
PROCEDURE Implose_tree IS
   node   ftree.node;
   htree ITEM;
   state varchar2(30);
BEGIN
   -- search the root ID --
   htree := Find_Item('BL_TREE.TREE_1');
   -- search the root --
   node := Ftree.Find_Tree_Node(htree, '');
   -- Collapse all nodes --
   WHILE NOT ftree.ID_NULL(node) LOOP
     state := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_STATE);
     IF state = Ftree.EXPANDED_NODE THEN
      Ftree.Set_Tree_Node_Property(htree, node, Ftree.NODE_STATE, Ftree.COLLAPSED_NODE);

ALV Tree - how to put checkbox on the node level?

Hello everyone!
I have an AlvTree and I have special column named SEL. That column contains checkboxes. I want to put additional checkboxes at the node level, I need them to create select all option.
In other words I must somehow create something similar to do_sum option. DO_SUM works for numeric columns, the sum of all rows in current node appears at the top level. So I must do the same but checkbox.
Are there any ideas?
Here is my code of creating the tree.
DATA: g_tree9001 type ref to cl_gui_alv_tree_simple.
" Here I fill fieldcat...
create object g_tree9001
      EXPORTING

        i_item_selection            = 'X'
        i_no_html_header            = 'X'
        i_no_toolbar                = ''.
call method g_tree9001->set_table_for_first_display
      EXPORTING
        i_save              = 'A'
        is_variant          = ls_variant

        it_sort             = gt_sort9001
        it_outtab           = gt_tree9001
        it_fieldcatalog     = gt_treefcat9001.
My output table gt_tree9001 has sthe following structure:
BUKRS, KTEXT, SEL, SWERK.
My sort table gt_sort9001 has 2 rows. Sorting by BUKRS and KTEXT.
My tree looks like this:
BUKRS/KTEXT --- SEL --- SWERK
+bukrs1 ------------------------------
-- ktext1 --- X --- swerk1
-- ktext2 --- X --- swerk2
+bukrs2 ------------------------------
-- ktext3 --- X --- swerk3
I want to get:
BUKRS/KTEXT --- SEL --- SWERK
+bukrs1 ----------X----------------
-- ktext1 --- X --- swerk1
-- ktext2 --- X --- swerk2
+bukrs2 ----------X----------------
-- ktext3 --- X --- swerk3

Suppressing empty nodes in ALV tree grid

Hi, I'm writing an ALV tree report with financial data broken down by cost element hierarchy. We've determined that the maximum number of levels in our hierarchy is seven so have to build the program to accept seven node levels. Most times when it runs it will find fewer than seven nodes. Is there an easy to to suppress empty columns in the report so that the end user does not not see a bunch of empty nodes in the report?

Expand or Collapse Branches or Hide Areas
You are able to expand and collapse the branches of the tree structure individually or together. Beyond that you are able to make a node or an item completely invisible.
