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.

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.

*** URGENT *** Hierarchical Tree *** URGENT ***

Hi,
following situation:
I have a tree item (ht) in a block TB_FRM_NAME within a help form. This tree is filled with the Module Names within the entire application.
I fill this in the WNFI:
Fpr_Fill_Tree_Item
( 'TB_FRM_NAME.HT' -- pi_tree_item_name
, 'rgp_fwe' -- pi_record_group_name
, 'SELECT b_fu_id , ' -- pi_sql_statement
||'level , '
||'bemerkung, '
||' NULL, '
||' NULL '
||'FROM b_funk '
||'ORDER BY bemerkung
The Content of the forms-procedure is:
PROCEDURE Fpr_Fill_Tree_Item
-- In-Parameter
( pi_tree_item_name IN VARCHAR2
, pi_record_group_name IN VARCHAR2
, pi_sql_statement IN VARCHAR2
) IS
-- Variablendeklaration
v_tree_item Item; -- fÃ¼r das Baumverzeichnis
v_rgp_id RecordGroup;
BEGIN
-- Initialisierung der Variable, Itemname holen
v_tree_item := Find_Item (pi_tree_item_name);
v_rgp_id := Find_Group (pi_record_group_name);
IF NOT Id_Null (v_rgp_id) THEN
-- Record Group existiert bereits, also lÃ¶schen
Delete_Group (pi_record_group_name);
END IF;
-- SQL Statement fÃ¼r die Record Group (Bedeutungen)
-- 1. Element Initial State
-- 2. Element Depth
-- 3. Element Label
-- 4. Element Icon
-- 5. Element Data -- when I enter Column name here
-- filling the tree doesn't work!
v_rgp_id := Create_Group_From_Query
( pi_record_group_name
, pi_sql_statement
-- Wenn die Record Group erstellt werden kann, ...
IF Populate_Group (v_rgp_id) = 0 THEN -- Fehlerlos
-- Record Group mit Tree verknÃ¼pfen
Ftree.Set_Tree_Property
( v_tree_item
, Ftree.Record_Group
, pi_record_group_name
END IF;
END;
After filling I want to add the names of the tab_canvas pages, when the user clicks one of the Modules in the application.
To test this I added following code in the WTNS Trigger:
-- Hier muss die nÃ¤chste Ebene des Baumverzeichnisses gefÃ¼llt werden
DECLARE
v_node Ftree.Node;
v_tree_id Item;
v_tree_level NUMBER;
v_tree_label VARCHAR2 (30);
v_tree_value VARCHAR2 (30);
BEGIN
v_tree_id := Find_Item ('TB_FRM_NAME.HT');
v_tree_value := Ftree.Get_Tree_Node_Property
( v_tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Node_Value
v_tree_label := Ftree.Get_Tree_node_Property
( v_Tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Node_Label
v_tree_level := Ftree.Get_Tree_node_Property
( v_Tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Node_Depth
IF v_tree_level = 1 THEN
v_node := Ftree.Add_Tree_Node
( v_tree_id
, :SYSTEM.TRIGGER_NODE
, Ftree.Sibling_offset
, Ftree.Next_Node
, Ftree.EXPANDED_NODE
, 'M'
, NULL
, 'M'
v_node := Ftree.Add_Tree_Node
( v_tree_id
, v_node
, Ftree.Parent_Offset
, 1
, Ftree.LEAF_NODE
, 'SUB'
, NULL
, 'SUB'
END IF;
END;
Result of this is, that the newly added node is placed at the first level of the tree. I don't want this! I would like to know what to do, so the newly added node is being shown at the second level.
Result
+-module1
|-module2
|-module3
Then the user clicks on module2 and the result is
+-module1
|-module2
--M
||-SELECT bemerkung FROM b_kat*
|-module3
Desired Result
+-module1
--module2
||-tab_page1
||-tab_page2
||-tab_page3
|-module3
*) Here I want the contents of the column to be displayed and NOT THE select statement.

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
lahore,pakistan

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.

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...

Finding proper help on Hierarchical Trees

Have spent a couple of hours trying to navigate the sprawling website of oracle.com with the purpose finding and then downloading the appropriate help file. I downloaded
Oracle9i Developer Suite Release 2 Documentation Library
from
http://www.oracle.com/technology/documentation/ids.html
Its about 130Mb, installed it, but could i find comprehensive documentation on using Forms 9i (in particular Hierarchical Trees) no, but everything else it seemed yes. The original doc that pre-installed with the 9i DS 'online help' is reasonably helpful but like some others on this forum I could not find proper help on how to use Hierarchical Trees all i could find was few descriptive portions of text and believe me i have looked.
Others have said they found examples of Hierarchical Trees usage i can only assume they are using 10g. So this is a desperate plea to you. Can you point me to an online resource that deals with Hierarchical Trees in Forms 9i (intro, usage, examples, etc). If you can i would deeply appreciate it.
Mr Frustrated :)

Hi,
You have a lot of sample With the Forms Help.
If you search in the index with "htree."
The command hierarchical tree complete list appear.

Hierarchical trees

Dear Sir,
I need to know whether I can use hierarchical trees in Forms 6.0. If yes, please send me the instruction to do.
And I need to know Client-Server architecture Application deployment.

Colourful Hierarchical Tree

Hi,
This is the first thread am posting. I searched ur discussions for "How to show the hierarchical tree in forms 10g with different colours and in different fonts weigth for different nodes". But i found nothing.
Hopefully looking forward for your replies.

You should use a less specific search string if you don't find anything first time but in this case it won't have helped you.
You can set an icon for each node in the tree, which might be an acceptable alternative to writing lots of java.
The icon can be set as a property
http://www.oracle.com/webapps/online-help/forms/10g/topics/f1_help/builts/set_tree_node_property_built_in.html?tp=true
or it can be built into the select statement that creates the tree (if your tree is query-driven).

Compiling error in Hierarchical Tree !!!!! Urgent attention!!!

I have made the Hierarchical Tree as described in the resuable demo help as is but when ever i try to compile the form i gets error on the navigator."anything!". I guess the forms are not able to find the navigator package. I have attached the navigator.pll. I think there is nothing mroe to attach to a form
Till now i have searched every documentation on the net and the files ships wiht DEV 6.0.5.2. But not ablet o find any thing regarding the installation of navigator package :( Is there any one can tell me how u remover the compiling error from the form which is dur to the navigator package!!!!
null

If you are using DEV 6.0.5.2 you should use the FTREE built-in package. Look under the Built-In package node. The Navigator.pll was a demo used in Forms4.5 before there was a hierarchial tree item type.

Can i have a check box in the hierarchical tree in the icons place, urgent!!! please

Hi,
I'am working on the Hierarchical Tree structure which should have three levels, I need to have a check box in the place of the icon & if i select a node that node & the child nodes should get selected.
After this when i say move selected ( i'am trying to use picklist class also) the entire checked tree has to move to the display area to the right & should display as tree structure & after this if i save then the checked records which are moved to another text area should get saved!!
How to achieve this? I have the tree structure ready but the check box part is the worrying factor! & then moving the checked records to the right using picklist class is the second problem & finally saving records to database.
Any help in this regard will be deeply appreciated:)
If check box is not possible then i will have to look at other methods, will the tree structure allow checkboxes????
Thanks
Mahesh

No the tree will not allow checkboxes

Add checkbox on the nodes of Hierarchical tree in oracle forms 9i

Hi,
I am working on oracle forms 9i.I have to add checkbox at the place of node(+/-) in Hierarchical tree so,
that user can select or deselect the Tree.That can do in oracle forms but how i don't know.
can anybody help me.....
Regards,
Hemant

You can't change this aspect of the Tree Control in Oracle Forms using built-in functionality. You might be able to extend the Tree Control using Java, but you have to do this yourself. : (
