* 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.

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

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.

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.

How to set the control-on hierarchical tree nodes

Hi,
I have created form in which at the left it has hierarchical tree structure(BOM) and towards the right it brings up the query results for selected node.
Now, I have a button upon clicking which I navigate to the root node by issuing
"Ftree.set_Tree_selection(htree, 1, Ftree.select_on);".
But, it cannot automatically run the ' when-tree-node-selected' trigger '.
any solution???
Its really urgent.I have a customer demo on monday.
Please help me asap.
regards,
Nagadeep.

Hello Nagadeep,
couldn't you just put the code from the trigger into a procedure
and run that after the navigation to the item?
Just a thought,
Bernd
The docs state that:
No programmatic action will cause the When-Tree-Node-Selected trigger to fire. Only end-user action will generate an event.
Probably due to performance reasons.

Hierarchical tree traversal..!!

Hi all,
I've populated a tree (Hierarchical tree - Ftree in Forms6i). Now I want to traverse it from the root node to the last nodes' last leaf....
How can i achieve this...
Please guide me through...
Very urgent
Thanx in advance...
RK Raju

a control block is one not based on a table/view/procedure . check the block's query data source name. its must be blank.
I suggest you create a procedure where you create the record_group using
CREATE_GROUP_FROM_QUERY,populate_group and ftree.set_tree_property
Here is my code that I i used to populate my tree .it works:
PROCEDURE populate_the_tree IS
grp recordgroup;
error_number number;
grpname varchar2(20) :='rg_group';
tree_id item :=find_item('ctrl.tree');
grp_qry2 varchar2(500) :='select -1,level,ename,null,empno from emp start with mgr is null connect by prior empno=mgr';
begin
     grp := find_group(grpname);
     if not id_null(grp)
          then delete_group(grp);
     end if;
--     grp := create_group_from_query(grpname,grp_qry1||grp_qry2);
     grp := create_group_from_query(grpname,grp_qry2);
     error_number:=populate_group(grpname);
     if error_number <> 0
          then message('Error while populating tree');
          raise form_trigger_failure;
     end if;
     ftree.set_tree_property(tree_id,ftree.record_group,grp);
END;

Need Simple Hierarchical Tree Example

Can someone e-mail me a simple, working hierarchical tree example, along with what tables i need to insert into the database? Like the car/airplane example, or employee/department example.
I tried following the instructions in the Introduction to Hierarchical Tree example from metalink, but the tree still does not display on my form, even though the data query is valid. Nothing happens when i click the button.
I need this pretty urgently, so any help will be appreciated! Thanks! My e-mail is [email protected]

Thats what i don't understand, you see. There is no query error. I know when there is, because when i type the query wrongly, the error prompts. However, when the query is correct, nothing happens. When i go through in debug mode, it does enter the statement to populate the tree. This is my record group/data query(i tried putting it in both) :
SELECT initial_level
,node_depth
,node_label
,node_icon
,node_data
FROM MyTreeData
START WITH node_parent IS NULL
CONNECT BY node_parent = prior node_data
This is my populate tree code :
DECLARE
     htree ITEM;
     top_node FTREE.NODE;
     find_node FTREE.NODE;
BEGIN
     -- Find the tree itself.
     htree := FIND_ITEM('mytreeblock.mytree');
     -- Populate the tree with data.
     ftree.Populate_Tree(htree);
END;
This is the format of data in the database :
initial_level node_depth node_label node_icon node_data node_parent
-1 2 Car Null CAR TRANSPORT
-1 2 Plane Null PLANE TRANSPORT
0 2 Bike NULL BIKE TRANSPORT
1 1 Transport NULL TRANSPORT
0 3 Honda NULL HONDA CAR
0 3 Boeing 747 NULL 747-400 PLANE
0 3 Mazda NULL MAZDA CAR
I hope its not a problem with my Forms program, so i'm hoping that someone can e-mail me a working one to see. I've been reading up on this for a few days already, but i do not know why its not working.
Thanks for your help again, Kevin! I really appreciate it.

How to go to a particular node in a hierarchical tree?

I want to do this simple thing with a Forms hierarchical tree.
Since tree has lots of levels and branches I want to give a search box.
User types the label and press a button. The form then has to query the tree node and expand ONLY the path where the node is (if found) and highlight it. If a node with a label is NOT found I give an error message to the user.
I got hold of a code segment to explode a tree and modified it, but it does not work. The entire tree is expanded and you don't know where you are.
Any help will be greatly appreciated?
PROCEDURE Expand_All_Nodes_in_Tree IS
     node ftree.node;
     htree ITEM;
     state varchar2(30);
BEGIN
     -- Search the tree identifiant --
     htree := Find_Item('menu.tree');
     -- 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);
IF Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_LABEL) = :ctrl.node_lable_to_search THEN
EXIT;
END IF;
     END LOOP;
END;

Hi Channa,
Try this code with you tree i am using the same situation and this code is working perfect with me.
PROCEDURE find_node_in_tree(search_string varchar2, find_type varchar2) IS
htree ITEM;
search_start_node ftree.node;
find_node ftree.node;
BEGIN
htree := Find_Item('blk_tree.main_tree');
     search_start_node := nvl(ftree.get_tree_selection(htree,1),ftree.root_node);
     find_node := ftree.find_tree_node(htree,upper(search_string)||'%',ftree.find_next,ftree.node_label,ftree.root_node,search_start_node-1);
     if find_node = 0 then
          find_node := 1;
end if;
Ftree.Set_Tree_selection(htree, find_node, Ftree.SELECT_ON);
exception
     when others then
          NULL;

Hierarchical Tree error - fighting for over a year

For over a year now, our Oracle forms have presented an elusive problem with Hierarchical Trees. First some core information:
We are running Developer 6i, patchset 8, on a Sun host and an Oracle 8i database. Our forms are deployed over the web on the
Oracle Application Server using J-Initiator 1.1.7.27.
Now, only on our Production platform, and only during busy times of the day, we randomly get the error "Invalid Query for Hierarchical
Tree" when one of our tree-based forms populates the tree. This error is sometimes followed by the infamous
FRM-92100 "connection has been terminated" error. This happens whether building the tree with a single Selec and Populate Treet,
or via a systematic series of Add Tree Node calls.
We have tried rebuilding the form logic to eliminate form corruption, (form corruption - happens if you open a large FMB in the
forms developer without first being connected to the database, manifests itself as random and odd form behaviour,
or FRM-92100 errors, Oracle product support denies it really happens), we have added debug code, we've even tried generating
the FMX on the Production platform as part of our deployment (normally we generate FMX files on our Integration platform
which mirrors Production).
We are not scheduled to upgrade for Forms 9i and the 9IAS for several more months, so upgrading isn't an immediate option for us.
Any and all ideas welcome.

Hi Nigel,
Two questions:
1. When the publisher sends the access permission to the subcriber by:
netStream.send("|RtmpSampleAccess", true, true)
, on the subscriber side, what event or function can handle the guaranteed receipt of the access permission? Currently it is possible to draw the incoming stream video upon receiving NetStream.Play.Star and waiting for 5 seconds or so:
public class MyWebcamSubscriber extends WebcamSubscriber {
override protected function layoutCameraStreams():void
// trying the event listener seems to work here.
_streamManager.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
override protected function onNetStatus(e:NetStatusEvent):void
super.onNetStatus(e);
case "NetStream.Play.Start":
setTimeout(function():void {
// draw the video from the incoming stream here.
}, 5000);
The questions is, which event can let the subscriber know that it has the access permission to the video stream?
2. In WebcamPublisher, why is that the access permission is sent 3 times?
a. Once on receiving NetStream.Connect.Success with 0.5 second delay, as in below.
b. Once immediately upon receiving NetStream.Connect.Success, as in below.
protected function onNetStatus(p_evt:NetStatusEvent):void
if (p_evt.info.code=="NetStream.Connect.Success") {
setTimeout(sendSnapShotPermission, 500);
_stream.send("|RtmpSampleAccess", true, true);
protected function sendSnapShotPermission():void
_stream.send("|RtmpSampleAccess", true, true);
c. Once in onConnectionTypeChange() with 2 seconds delay:
protected function onConnectionTypeChange(p_evt:StreamEvent):void
if ( _streamManager.isP2P) {
_stream= new NetStream(_connectSession.sessionInternals.session_internal::connection as NetConnection,NetStream.DIRECT_CONNECTIONS);
setTimeout(sendSnapShotPermission, 2000);

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.

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. : (

Can I use Hierarchical Tree from Forms6.0 in Forms5.0

Hello
The Oracle Custumer Support tell me that it should be possible to
use Hierarchical Trees also in Forms5.0
I look for a possibility to build a Navigator in Forms5.0
with Symbols. (look and feel like the Navigator in Forms6.0 if I
use Symbols in the Record Group).
I Description should be on
http://developer.us.oracle.com
but either i have no access to this side or
the URL is false.
Sure is that there is a description over this Problem.
And i have to get this description ;-)))

That is not recommended. The new code editing features do not play well with an old workspace.

Make an hierarchical Tree in oracle Forms 6i

Hi everybody,
I want to make an hierarchical tree. I work in Forms 6i
I create one non database block e.g. 'Bloc2' then
add hierarchical control item in that. e.g 'Menu'.
I create a record group named 'RG_DATA_TEST'
Before I use a table in this record_group.
I want a tree as this :
- Menu1
Menu1 option1
Menu1 option2
- Menu1 option3
Menu option3 Sub opt 3
+ Menu2
the table 'Menu_tree' is described' :
CREATE TABLE MENU_tree
ID NUMBER(5),
LABEL VARCHAR2(128 BYTE),
ICON VARCHAR2(40 BYTE),
MASTER NUMBER(5),
STATUS NUMBER(1) DEFAULT 1,
VALUE VARCHAR2(128 BYTE)
Here the data in the table :
INSERT INTO MENU_tree ( ID, LABEL, ICON, MASTER, STATUS, VALUE ) VALUES (1, 'Menu1', 'mainmenu', NULL, 1, NULL);
INSERT INTO MENU_tree ( ID, LABEL, ICON, MASTER, STATUS, VALUE ) VALUES (
2, 'Menu1 Option 1', 'optionmenu', 1, 1, 'Dialog11');
INSERT INTO MENU_tree ( ID, LABEL, ICON, MASTER, STATUS, VALUE ) VALUES ( 3, 'Menu1 Option 2', 'optionmenu', 1, 1, dialog12');
INSERT INTO MENU_tree ( ID, LABEL, ICON, MASTER, STATUS, VALUE ) VALUES (4, 'Menu1 Option 3', 'optionmenu', 1, 1, NULL);
INSERT INTO MENU_tree ( ID, LABEL, ICON, MASTER, STATUS, VALUE ) VALUES ( 5, 'Menu1 Opt 3 Sub Opt 3', 'suboptionmenu', 4, 1, 'Dialog131');
INSERT INTO MENU_tree ( ID, LABEL, ICON, MASTER, STATUS, VALUE ) VALUES ( 6, 'Menu2', 'mainmenu', NULL, -1, NULL);
INSERT INTO MENU_tree ( ID, LABEL, ICON, MASTER, STATUS, VALUE ) VALUES ( 7, 'Menu2 Option1', 'optionmenu', 6, 1,'Dialog21');
The record_group use this instruction SELECT :
SELECT STATUS, LEVEL, LABEL, ICON, VALUE
FROM MENU_tree
CONNECT BY PRIOR ID = MASTER
START WITH MASTER IS NULL
And At the trigger When_new_form_instance , i do this code :
DECLARE
htree ITEM;
V_IGNORE number;
BEGIN
HTREE := FIND_ITEM('BLOC2.MENU');
V_IGNORE := POPULATE_GROUP('RG_DATA_TEST');
FTREE.POPULATE_TREE(htree);
END;
When i run the forms, It don't give me a structure of node.
It give me only a icon with two arrows.
Where is the problem ?
Must I add code somewhere ?
Help me for your ideas.
Regards.

Ok Francois Thanks for your response.
Just I pricise i work with oracle forms version 9.0.4.0.19 .
But I am putting this code in trigger When_New_form_Instance but it didn't work.
When I execute it just shows a line with two arrows but not a real tree.
Then I do a block-non based and a elemnt with type hierarticall tree and a canevas.
and i create a record_group. and in a palette property of the element i precise the canevas and the record_group
I don't khnow where is the problem ?
Any other suggestion ? please

Hierarchical tree item - how to improve performance

I'm loading hierarchical tree item with query.
Problem is that it takes very long to load all the items(300, but can be more) to the hierarchical item.
Query takes 0.5 sec., but loading it into the item with Set_Tree_Property(htree, Ftree.RECORD_GROUP
the code:
PL1 := Create_Group_From_Query('pl1', query);
v_ignore := Populate_Group(PL1); -- 0.5 sec
Ftree.Set_Tree_Property(htree, Ftree.RECORD_GROUP, PL1); -- 3 sec.
Does anyone have any idea what to do to improve tree loading?

Hello,
try to play a little bit with the state-column of your query. If you only display the first hierarchy level
and set the state of the "hidden" nodes to open, I think ist is the state 1, then it works much faster.

Connect by prior working in sql but not in forms 10g hierarchical tree

Hello Friends,
I have the following connect by prior example which is working in sql command prompt but not in Forms 10g hierarchical tree item type. Can you please let me know why ?
configuration: Forms 10g patchset 10.1.2.0.2 and oracle 11g database on windows 7
SQL> SELECT 1 InitialState,
2 level Depth,
3 labeller NodeLabel,
4 NULL NodeIcon,
5 to_char(reportno) NodeValue
6 FROM reports where formname = 'billinin.fmx' or reportno > 9999
7 start with reportno > 9999
8 CONNECT BY PRIOR reportno = labelno
9 /
INITIALSTATE DEPTH NODELABEL N NODEVALUE

1 2 report1 UD Label 1
1 2 report2 UD Label 2
1 2 report3 UD Label 3
1 1 SECOND 10001
1 1 THIRD 10002
If I write this command in forms hierarchical tree, then it is working, why not the above code ?
SQL> SELECT 1 InitialState,
2 level Depth,
3 labeller NodeLabel,
4 NULL NodeIcon,
5 to_char(reportno) NodeValue
6 FROM reports
7 start with reportno > 9999
8 CONNECT BY PRIOR reportno = labelno

Thanks Room,
This command worked ! I will put the sample working code here. It will help you to filter the records in a tree in sql command prompt as well as in forms hierarchical tree 10g.
SELECT 1 InitialState,
level Depth,
labeller NodeLabel,
NULL NodeIcon,
to_char(reportno) NodeValue
FROM reports
start with reportno > 9999
CONNECT BY PRIOR reportno = labelno
AND FORMNAME = :reports.testitem
