Hierarchical Tree -- Forms 6i

Forms 6i patchset 18 c/s
I am having am issue with hierarchical tree misbehaving itself once the nodes get greater than 1600 or so.
The tree graphics get malformed and the vertical scrollbar, even when scrolled all the way down will not let you see all of the nodes.
1) does anyone know of a node limit in 6i or a workaround?
I did check Forms 11gR2 by recompiling my form in 11gR2 and everything behaves fine, so I know the issue has either been fixed or is only an issue on c/s versions of forms.
Thanks,
Chris

I am having am issue with hierarchical tree misbehaving itself once the nodes get greater than 1600 or so.Well, I'm sure you will admit that 1600 nodes is a lot of nodes! Forms 6i was de-supported a long time ago and as I recall, patchset 18 was the last released patch for Forms 6i (I could be wrong - it's been a while since I worked with Forms 6i so I could be wrong). The fact that you have the "latest" patchset available for Forms 6i suggests you have a support agreement with Oracle. If this assumption is correct, you could check My Oracle Support (MOS) to see if there were any one-off patches released after Patchset 18 and try them to see if they fix the issue.
If there are no one-offs or smaller patches after Patchset 18 then you will likely need to look into ways to alter how you display nodes to reduce the number of nodes or possibily upgrade to a supported version of Forms (Forms 11g R2).

Forms Builder-hierarchical tree(expanding and collapsing nodes)

hi friends,
can anyone help me with populating my hierarchical tree form by using codes for collapsing and expanding?
for instance when_button_pressed:
tree_control.expand_all(tree_control.v_item_name); //this is for expanding all the nodes in the tree structure
well, i have an sql statement in my record group which in turn defines the structure of the hierarchical tree.
Is it possible to just use the codes 'tree_control.expand_all(tree_control.v_item_name);' like that in the when-button-pressed trigger?
Thanks for any help :)

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

Hi,

that user can select or deselect the Tree.That can do in oracle forms but how i don't know.
can anybody help me.....

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. : (

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

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 1 FIRST 10000
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

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.

Hierarchical tree - Data Entry Form

I am trying to make a data entry form for hierarchical tree. Any one help me to send a sample .fmb file.
I created a table like
create table master_ACTIVITY
(INITIAL_LEVEL NUMBER (4) ,
NODE_DEPTH NUMBER (4) ,
NODE_LABEL VARCHAR2(160) ,
NODE_ICON VARCHAR2(60) ,
NODE_DATA VARCHAR2(160) ,
NODE_PARENT VARCHAR2(160)
1. How do i use hierarchical tree for adding and deleting item into it.
2. In my other form i use the item from hierarchical tree. so how to get the return value of the selected item in a hierarchical tree. and which of filed in this table i need in other forms to connect to this table and get values.
please send a sample form to [email protected]
thank you

Andreas,
It got worked.
I have another problem now. I have 2000 records in my tree. when i populate it is taking time to populate.
I want to display only parent trees ie Level 1 & 2 Items. But the Level 1 & 2 should have '+' symbol to display.
When the user click on any items in level 2, only then the child of the selected parent should populate.
By default all the items are displayed in collapsed mode (-1). But still it take time to populate.
Any solution ?.

Hierarchical tree not showing up while running the form

Hi Gurus,
I have a problem while running forms in 10g AS.
The hierarchical tree control is showing up when I run the form in my local development (win xp) system. But, when I run the same form through my 10g Application server(linux), the hierarchical tree control is not showing up.
Can anyone suggest some solutions ?
Thanks in advance.
Sundar K

Hi Andreas,
Thanks for the reply.
The form shows a blank square-box, instead hiearchical tree. I can see other controls like text-box, LOV, command button on the same form.
The java console shows,
Downloading http://test.abits.com:7778/forms/java/frmall_jinit.jar to JAR cache
Downloading http://test.abits.com:7778/forms/java/f60tree.jar to JAR cache
proxyHost=null
proxyPort=0
connectMode=HTTP, native.
Forms Applet version is : 10.1.2.0
The problem persist, even though I change the appsweb.cfg file to use frmall.jar instead of frmall_jinit.jar.
I'm using 10g application server (iAS 10.1.2.0.2).
Kindly advise. Thanks in advance.

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

Hierarchical tree in web forms 10g - form freezing

I have an application with an hierarchical tree on one of the forms - the application worked fine as client/server back in forms 6 but now that it is web enabled in 10g there are problems with the tree causing the form to freeze, then the entire application has to be closed. It doesn't seem to matter if you are selecting a node or creating a new node both have caused the form to freeze. It doesn't happen all of the time but it seems that the longer the application has been in use the more it starts to freeze. Any ideas? Is there a known problem with trees in web forms? Thanks

At the root of my tree is a patient (I work in the health care industry) and then for that patient there are clinic visits, surgeries, etc (there are 16 nodes at this level). and under each of these are dates when the visits occured (there can be an unlimited number of nodes at this level). This is some of my code for populating the tree:
if :GLOBAL.patient_seq is not null then
-- turn the tree on
set_item_property('tree_block.tree_item', ENABLED, PROPERTY_TRUE);
set_item_property('tree_block.tree_item', NAVIGABLE, PROPERTY_TRUE);
lv_tree_id := find_item('TREE_BLOCK.TREE_ITEM');
--refresh the tree back to it's original state from the database
Ftree.Set_Tree_Property(lv_tree_id,
     Ftree.RECORD_GROUP,
     FIND_GROUP('TREE_GROUP'));
-- create the clinic visits branch
wcchn_tree_items_pkg.get_visits(lv_visit_table, :global.patient_seq);
for lv_counter in 1.. lv_visit_table.count loop
lv_site := wcchn_locations_pkg.get_location_code(lv_visit_table(lv_counter).site);
create_visit_node( lv_visit_table(lv_counter).visit_date || ' - ' || lv_site,
     lv_tree_id,
lv_visit_table(lv_counter).seq_nr);
end loop;
Below is the procedure referred to in the above segment of code:

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.

Call forms and reports from a hierarchical tree node.

Hello,
I am new in pl/sql programming and I have some dificulties. I have created a hierarchical tree, in order to use it as a menu in an application that I am trying to develope. The problem is that I do not know how can I make the last nodes to be either a form or a report and when somebody double clicks on these nodes the form or the report will run. What is more, should I use the when-tree-node-selected trigger or the when-tree-node-activated?
Thank you in advance,

Hi ,
In Oracle Forms , a hierarchical tree is developed through the use of a sql statement and column which defines the order of leaves...
Visit the on-line help of Forms10g to find out the details , and the triggers as well...
Something else...post this question to Oracle Forms to get more detailed answer...

Thank you very much for your reply. I tried what you said and managed to create a when-tree-node-activated trigger that works fine. The only problem is that I do not know how to find the last 3 characters of every node in order to make the form understand if it is a form or a report. I mean that the name of each node maybe of different length so I do not know how exactly to use the substr().
Thank you
