Tree in WD ABAP - urgent

HI Experts,
I am working on WD for ABAP.
I am using a tree to display some data. Node1 points to Root and subnode1 point to node1.
node1-->root
subnode1--> node1
When we expand node1, it shows ">" (arrow) for child nodes.
and if we further expand chld node(sunbnode1) we can see "." (Dot)
As per my requirement IF the node1 does not have any value for subnode1 than node1 should not show ">" , istead of that it should how "." for that child node.
could anyone plz tell me ....
1)how can I solve this.
2)How to use recursive node. I have never used recursive nodes.
PLease reply ASAP. Its very urgent.
for helpfull answers full points would be rewarded.
Regards,
Vishal.

Hi,
When you work on Tree, you should remember 4 important attributes.
expanded, parent row key, row_key and is_leaf.
To add children to parent we will have to maintain the relationship between row_key of PARENT and parent_row_key of CHILD.
if row_key = 1, then parent_row_key shoud be eqaul to row_key of parent, so that the corresponding childs will get added to parent.
if u put is_leaf = 'X'., then it means that they bcome childs(no longer exapndable ".")
and when u expand a parent, then expand = 'X'.
Provide Reward points.

ALV Tree in WebDynpro ABAP

Hi,
In my present project we have requirement for developing ALV tree output using ALV configuration model in WD4A. Please provide sample code or tutorial related to ALV Tree development in WebDynpro ABAP.
Best regards,
Alleiah

There is no hierarchy of nodes when building an ALV or Table Tree in WDA. You still provide a flat structure of a single node. What you do is specify certain columns to be hierarchy columns. The framework then builds a sorting/grouping around these columns and turns them into the "pesudo nodes" of the tree.
This can be done via configuration or via coding:

For instanace, taking the same flat SFLIGHT structure I can just define certain columns and create two different hierarchies:

Program to add node / delete node in the tree control via abap object

Hi all,
i am new to abap objects.
Can anyone help me out to give program about add node , delete node at
a particular point in tree hierarchy.
folder1 -- level 1
subfolder1 -- level 2
*********subfolder1 -- level 3
*********subfolder2 -- level 3
subfolder2 -- level 2
folder2 -- level 1
if i select level3 and click on ADD button .....i get a facility to add new node
at level 3 and and same thing can happen at level1 and level2 ............ if i select
and folder at level3 and click on delete button ....it should delete that folder...
if you do not have such program ........then guide me how to achieve this target via object oriented because i have to split the screen also and have to show some alve display in that.
just guide me how to add and delete node at a particular level in tree structure....
thanks in advance........

Tree-Control in ABAP redifinieren

Hi there,
I would like to use my tree as navigation-menue. In this case, the alphabetical order of the entries is not used. I would like to specify the direction by myself. Is there any possibility to change or redefinate the abap class cl_wd_tree and how should I implement the changes into my application.
Kind regards,
Albert

Hi Albert,
Redefining the class won't make a difference, since there won't be a renderer for your new class - including a number of other required settings/objects/interfaces.
Well, nonetheless there is a way to achieve what you want. You could use a ContextualNavigationPanel and there inside a NavigationList.

A Binary Tree Implementation in ABAP

Hi,
Can any one explaine me how to create a binary tree of random numbers with dynamic objects.
Thanks,
Manjula.

Hi manjula,
This sample code uses dynamic objects to create a binary tree of random numbers as per your requirement ...pls go through It.
It stores numbers on the left node or right node depending on the value comparison with the current value. There are two recursive subrotines used for the building of the tree and printing through the tree.
For comparison purpose, the same random numbers are stored and sorted in an internal table and printed.
*& Report YBINTREE - Build/Print Binary Tree of numbers *
report ybintree .
types: begin of stree,
value type i,
left type ref to data,
right type ref to data,
end of stree.
data: tree type stree.
data: int type i.
data: begin of rnd occurs 0,
num type i,
end of rnd.
start-of-selection.
do 100 times.
generate random number between 0 and 100
call function 'RANDOM_I4'
exporting
rnd_min = 0
rnd_max = 100
importing
rnd_value = int.
store numbers
rnd-num = int.
append rnd.
build binary tree of random numbers
perform add_value using tree int.
enddo.
stored numbers are sorted for comparison
sort rnd by num.
print sorted random numbers
write: / 'Sorted Numbers'.
write: / '=============='.
skip.
loop at rnd.
write: rnd-num.
endloop.
skip.
print binary tree. This should give the same result
as the one listed from the internal table

skip.
perform print_value using tree.

Data retrieval from a loaded tree in WD ABAP

Hi All,
I have a node 'ENTRY' and have a recursive sub node called 'SUB_ENTRY' now assume that i have created a 10 level tree by creating 9 recursive nodes. Now i would like to fetch or retrieve all the data from this tree.
So can you pls tell me if there exists a method to do it in one go or will i have to use GET_TABLE_FROM_NODE for every node ..
Thanks for your help.
Regards,
Anoop

Yes Thomas you are right about the use of ByKey and NestingColumn but the thing is that as far as application development is concerned then i am done with that .. but it was to improve the performance of this application that i needed to know if i can retrieve the already available data from this tree instead of calling the FMs again which is very costly ...
anyways thanks for your response.
Regards,
Anoop

Expand tree in WebDynpro ABAP application

Hi,
Currently I am working on a WDA application which contains a UI ELEMENT TREE. The tree is generated dynamically at runtime.
I was guided by the example of SAP "WDT_TREE". After generating the tree looks like this:
TREE
   | __ NODE1
           | __ LEAF1
           | __ LEAF2
           | __ NODE2
                | __ LEAF3
           | __ Node3
                | __ LEAF4
                | __ LEAF5
                | __ LEAF6
Now I have bound the "expanded" property of the node to a context element and execute the following action in the WDDOINIT:
* Fill tables with the structure of the tree
fill_foldertable( ).
fill_filetable( ).
lr_current_node    = wd_context->get_child_node( 'FOLDER' ).
lr_current_element = lr_current_node->create_element( ).
lr_current_node->bind_element( lr_current_element ).
lr_current_node->set_lead_selection( lr_current_element ).
lr_current_element->set_attribute( name = 'TEXT' value = 'Products' ).
lr_current_element->set_attribute( name = 'IS_EXPANDED' value = 'X' ).
* Create the root node
create_node(
    EXPORTING
      cur_element = lr_current_element
      parent_key = 'Categories' ).
Now the tree is expanded, but i can't see EAF1 and LEAF2. I get them only by clicking again on node1.
Any ideas?
Regards.

Hi All,
I found the solution for my question. Expand tree in Webdynpro application
Soultion
In the context node i.e used as a source for tree, you create a attribute
Attribute Name: IS_BOOLEAN
Attribute type : WDY_BOOLEAN
Default Value : X
And in Context node Un check the Initialization lead selection.
Now bind the Expand property of TreeNodeType with 'IS_EXPAND' which you have created just now.
This way the whole tree will be expanded.

Implementation of Tree Strucure in ABAP

Hi,
I have to display a report in the tree structure.
 --->Node....
Root Node------>Node....
--->Node.....
>Node....
The report goes like this...Is there any way to implement the same. I have to display the report in ALV.
and it is interactive.
Thanks in advance,

hi sumanth,
you can use htmln:Tree tag for ur problem
u try this code,
<htmlb:tree id = "t1"
 title = "t1"
 tooltip = "Tooltip for t1"
 toggle = "X" >
 <htmlb:treeNode id = "n1"
 text = "n1"
 image = "@09@" />
 </htmlb:treeNode>
 <htmlb:treeNode id = "node3"
 link = "http://www.xyz.com"
 text = "Node3"
 isOpen = "true"
 image = "@A0@" />
 </htmlb:treeNode>
 </htmlb:tree>
u can similarly add any number of trees and their nodes.
and u can also define events in eventhandler corresponding to each child.
try this code in event handler
DATA: event TYPE REF TO CL_HTMLB_EVENT.
event = CL_HTMLB_MANAGER=>get_event( runtime->server->request ).
IF event IS NOT INITIAL AND event->name = 'tree'.
 DATA: tree_event TYPE REF TO CL_HTMLB_EVENT_TREE.
 tree_event ?= event.
ENDIF.

Sample ALV Tree in ABAP Wed Dynpro

Hi Guys,
I tried to create a ALV with TREE column in ABAP Web Dynpro.
Do you have any sample for this?
Thanks.
Tee

Following 2 things are the most important steps
"A) identify the table as hierarchy table:
wd_this->go_table->if_salv_wd_table_settings~set_display_type( if_salv_wd_c_table_settings=>display_type_hierarchy).
(wd_this->go_table is the reference to wd alv object:)
"B) mark the columns you want to have as nodes with following statement:
ls_col-r_column->if_salv_wd_column_hierarchy~set_hierarchy_column( value = abap_true ).
(ls_col is reference to the column)
Also you can check standard component salv_wd_demo_table_tree

WD Abap - Tree

hi folks,
i'm working with the Element TREE and now i'm wondering if it is possible to build a tree like that (similar to the tree in sapgui abap):
node
-subnode
-subnode Item1 Item2 Item3
Because all my Item-Fields are always in the next row after the subnode?
kind regards oliver

Hi Oliver,
>I guess the Nesting Tree in a Table could work, am i right?
Yes. Another option would be to use the *ByKey version of the hierarchy column. Using it, you don't need to have a recursive nodes in the context, but a only a single non-recursive one. The parent relationship needs to be expressed via two attributes of this node, one containing the id of the current item and the other one the id of the parent under which it will appear once rendered (there are corresponding attributes in the ui elements, which have to be bound). Btw. There is no need to order the elements concerning their parent relationship. The renderer does that automatically.
Kind regards,
Thomas
