Hierachial Tree in Forms

Im populating a tree in forms.eg
Adminstration
Setup
Lookup
Now if i click on the Lookup i want to get the path that is "Administration/Lookup".
Is there any way to do this without using the sys connect by path function.Im storing the path in the table.

you can write a function with given pl/sql
declare
l_temp varchar2(200);
begin
for i in (
select empno, mgr
from emp
connect by prior mgr=empno
start with empno=7900
loop
l_temp := l_temp||'\'||i.mgr;
end loop;
dbms_output.put_line(rtrim(ltrim(l_temp, '\'), '\'));
end;
when the node is selected, pass the ID to this function and this returns the string for you.
this is bottom-up approach. you select the node and get all its ancestors.
good luck.

Problem creating a hierarchical tree in forms builder[issue with the query]

Hi all,
I have 2 tables.
box (box_id, box_name)
item(item_id, item_name, box_id)
In a box there are several items.
I want to create a hierachical tree to display items that are present in each box.
LIKE:
|---BOX1
| |----ITEM 1
| |----ITEM 2
|
|---BOX2
| |----ITEM 1
| |----ITEM 2
Currently i am trying this query:
SELECT -1 state, box_name, 'icon' icon, box_id val
from box b, item i;
I don't know what value to put for level, i don't know how to code the 'connect by prior' part.
Could you please advise me?
Michaël.
PS. Then i will eventually use this query in forms builder.

Hi MichaelR
i get the FRM - 47321 error in forms builder ..
Hence In order to populate a tree, the Select order must retrieve 5 columns:
STATUS, LEVEL, LABEL, ICON, VALUE u should notice this orders in ur Query this will solve the error and pls notice that the...
My advice is to use the On Line help in ur forms builder to help u in this ...
Initial state : number
Node tree depth : number
Label for the node : varchar2
Icon for the node : varchar2
Data : varchar2This should be in WHEN-NEW-FORM-INSTANCE-trigger in order to populate ur tree...
another thing why don't u think of building ur tree as i did here in the following example...Pls have a look here ....
Hope this helps...

Hierarchal tree in FORMS

Hi,
I have a hierarchal tree table that I want to represent using forms (insert and update data in the tree table).
Are there any LINKS or documentation that can help me with my little project :-)
Thanks,
Marc.

The help file has a fairly detailed description of how to manipulate the tree control.
Provided you have a table that can do this I would do "connect by prior" and "start with" SQL statement and use the pseudo column called "level" to determine when to create a new sub tree and when to end it.

Creating a Hierarchical Tree in Forma 6i

Hi Gurus,
We are using forms 6i and oracle 9i. In oracle forms i have one control block and another control block. When we click on one column repname ,the other control block displays the
corresponding info for the sales rep name. eg. Lets say i pick John the salesrep in the other
control block it displays its code,geography region etc.
I want to create a hierarchical tree in the other block where it is displaying the salesrep info.
So i want when i click on the sales rep name(the other control block measure)
then it should the code,geography region etc in the form of hierarchical tree in the other control
block. If the sales rep name is not clicked then the control block having the salesrep info should be hidden.
I would appreciate your help.
Thanks,
PSO

place your treeitem in the layout. The treeitem has to the only item in the block and property "Single record" has to be true.
To populate your tree with data you can either
- use a query to populate a treeitem have a look at this thread Tree Menu
- use the Ftree.Add_Tree_Node built-in and program your own logic.

Hierarchical trees in forms

in my oracle forms application i'm working with hierarchical
trees; every time the tree displays all the nodes are expanded,
but i want all of them to be collapsed, i tried to set the
properties of the tree with ftree.collapsed_node, but i only got
an error message that i didn't select any node.
Can somebody help me?

Dear Friend,
Try this piece of code this will solve your problem
tree_item:=find_item('your tree item');
find_node:=ftree.find_tree_node(tree_item,'your_Node_name',
ftree.find_next,ftree.node_label,
ftree.root_node,ftree.root_node);
ftree.SET_TREE_NODE_PROPERTY
(tree_item,find_node,ftree.node_state,ftree.collapsed_node);
do the neccessary changes and apply

How to call forms using Hierarchical Tree in Forms 10g?

I know how to call forms from menu that attached to a top form.
I would like to call forms using Hierarchical Tree. Does any one know how where I can find some instructions on using Hierarcical Tree to call other forms? Any discussion is welcome. Thanks.

Thanks to Francois.
The exampe with clear instructions and I can build tree that calls forms now.
I add a OPEN_FORM statement in WHEN-TREE-NODE-ACTIVATED trigger
Declare
     LN$I Pls_integer ;
Begin
:Ctrl.Node_Activated := Ftree.Get_Tree_Node_Property('BL_TREE.MENU', :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE) ;
If :Ctrl.Node_Activated IS NOT NULL Then
     Set_Alert_Property( 'AL_CALL_FORM', ALERT_MESSAGE_TEXT, 'Calling module : ' || :Ctrl.Node_Activated ) ;
     LN$I := Show_Alert( 'AL_CALL_FORM' ) ;
     open_form(:Ctrl.Node_Activated);
End if ;
End ;
Or call physical form path by:
     open_form('c:\tree\'||:Ctrl.Node_Activated ||'.fmx');
I enter the VALUE of MENU as the Form fmx name and it works very well.
Thanks so much.

Hierarchical tree in forms 10g

dear member.
i am a beginner. and want to know about that how to make hierarchical form
i am using developer suit 10g.
thanks

Mustafa,
the way u have marked the node_id and parent_node_id in the two tables, it is done at form level. or what... this is a little confusing to me, i have to apply that ht form at other schema.Yes, I create Record Group that populates the HT in the When-New-Form-Instance (WNFI) trigger. You can populate an HT from just about anywhere, but I use the WNFI to ensure the tree is populated when the form loads.
To add a "Grandchild" node to your tree, you simply need to modify the WNFI trigger and add a Loop for these nodes. Using your data as an example, the code in the WNFI would look something like this (not tested):
DECLARE
   CURSOR c_comp IS
      SELEC T compcode, name
        FRO M company;
   CURSOR c_div (p_comp NUMBER) IS
      SELEC T div_id, div_name, dept_id
        FRO M s_div
      WHER E compcode = p_comp;
   CURSOR c_dept (IS
      SELEC T dept_id, dept_name
       FRO M s_dept
     WHER E dept_id = p_dept;
   n_level NUMBER := 1;
   n_row NUMBER := 1;
   rg_id RECORDGROUP;
   node Ftree.Node;
BEGIN
   Tree_Control.v_item_name := 'MY_TREE_DATA.MY_TREE';
   rg_id := Tree_Control.Create_RG;
   <<parent>>
   FOR r_comp IN c_comp LOOP
      -- Add Parent Company
      Tree_Control.ADD_RG_ROW(rg_id, ftree.collapsed_node, n_row,
              n_level, r_comp.name, null, r_comp.compcode);
      n_row := n_row + 1;
      n_level := n_level + 1;
      -- Add any child Department records
      <<child>>
      FOR r_div IN c_div(r_comp.compcode) LOOP
         Tree_Control.ADD_RG_ROW(rg_id, ftree.collapsed_node, n_row,
              n_level, r_div.div_name, null, r_div.div_id);
         n_row := n_row+1;
         -- Now, add any Grandchildren
        <<grandchild>>
        FOR r_dept IN c_dept(r_div.dept_id) LOOP
           Tree_Control.ADD_RG_ROW(rg_id, ftree.collapsed_node, n_row,
               n_level, r_dept.dept_name, null, r_dept.dept_id);
        END LOOP grandchild;
      END LOOP child;
   END LOOP parent;
   ftree.Add_Tree_Data(Tree_Control.v_item_name, ftree.ROOT_NODE,
                   ftree.PARENT_OFFSET, ftree.LAST_CHILD,
                   ftree.RECORD_GROUD, rg_id);
END;You will still need to modify the Create_RG function in the Tree_Control package to support the above changes, but this code sample should get you started.

Download the Step By Step Guide to Create a Tree in Forms

hi,
I have developed a sample form for Tree Item. Anybody who doesn't know how to create a Tree Item in form can visit the page and download the step by step guide from there. There is a sample form, sample table data, one document describing the whole process and pictures which is a step by step guide.
Please Note: The document there is from Oracle. I didn't change anything in it. I just developed the form by going through the step from the document.
Please visit this site
http://www.saadatahmad.freeservers.com/tree.htm
Thank you

Thanks for your comment. I think it's always good to share the stuff this way instead of informing the people like "hey, I have this stuff. mail me if anybody wants", which I think is not the good way as you mentioned.

URGENT *** Hierarchical Tree in Forms 9i *** URGENT

Hello everybody,
for my company I need to build a hierarchical tree item, that will display static data over three levels. Let's say: departments, employees and employee projects.
How do I fill the Item?
When do I fill the Item?
Where do I fill the Item?
What are the elements of the SQL query, that fills the hierarchical tree?
Any help will be appreciated
[email protected]

Note:210663.1 helped a bit.
I used the database column as the third element in the select part and put NULL as the fifth element. Then it worked.
Now I am looking for the way to add the employees, when the user selects / activates a department node.

How to modify a tree component dinamically

Hi to everybody. I'm a problem with RichTree component when I try to run my application in jdeveloper 11g.
In jsp page I have a RichInputText and a button component. When you click on the button, it modifies one String type variable: it stores the same value of RichInputText component.
After that the applicatiion should show a tree that use the modified variable before, but when I click on the button an exception occurs:
