SEARCH item in MULTI-SELECT LOV (Hierachical Tree)

I have created a multi-select LOV using a hierarchical tree; providing the query for the tree in the Functional/Data Query property.
The Multi-Select LOV works fine. As you would suspect some LOV's have long lists that one must scroll through.
I would like to implement a SEARCH field (as seen in Forms standard LOV functionality) that will search through my Tree Node values and highlight the item searched (again as the standard LOV functionality works). Thus, allowing the user to quickly find the values in the list.
How do I go about referencing the Tree Node values to the value in the search (field) item?

Hello,
Search, through the FTree package's functions, those that allows to navigate through the leaves.

Hierachical Tree node(help me please)

Hi experts,
JDEV 11.1.2.0.0
i hav 3 tables say category_1 ,category_2(FK - cat1_code), & category_3( FK - cat1_code&cat2_code)......
I created a BC from these tables and also created a view link from category_1 to category_2 & another view link from category_2 to category_3....
then i made a hirearchical tree stucture to display database items....i converted all node to a Command link....
My usecase is follows.......
when i click each hierarchical link(data fetched from table) it should navigate to its master form for creating a new master a record.....means , if i clicked a category_1 data , it should navigate to category_1 master form to create a new record.....
I almost done for my use case.....but i dnt knw how we can get corresponding iterator binds from tree definition ......this my page data binding definition

Hierachical tree - Highlight particular node's in Tree

Is there any way to bold or change the colour of particular nodes in a tree?
We know and use the node icon to distinguish between them but ideally would want to bold some to highlight areas
I can not see how to do this looking at the documentation but may be wrong.
Thanks

Thanks thats what i thought but hoped i was wrong.

Click on the searched hierachical tree node

Hi,
when i search the hierarchical tree for a string then all the matching nodes come selected.Then when i click on any of the search result nodes it does not work and otherwise i have to click on a non selected node and then click on the desired node .
For example i have created a tree for material used for manufacturing purpose.i want to display the related suppliers names in an adjacent grid by clicking on the node in the tree. how can i do that directly after getting the search node.??

i hope i get you
i think you have a form contain a block for tree and another block build on a database table and you want to execute query on the block when you select a node
and you have a search item to seach for a node and want to go to the block record when you clock on search without go to the node and select
try this in search button or when-validate-item of the search key
-- create a pkg specifiaction called tree_pkg and define the follwing variable
--node ftree.node;
PROCEDURE select_node IS
     node ftree.node;
     htree item;
     node_label varchar2(3000);
node_val varchar2(3000);
     state varchar2(3000);
begin
     htree := find_item('BLOCK.TREE_ITEM');
     node := Ftree.Find_Tree_Node(htree, '');
ftree.set_tree_selection(htree,node,ftree.select_on) ;
WHILE NOT Ftree.ID_NULL(node) LOOP
     state := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_STATE);
node_label := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_label);
node_val := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_value);
if upper(node_label) like <your search item> then
ftree.set_tree_selection(htree,node,ftree.select_on) ;
tree_pkg.node := node;
exit;
end if;
node := Ftree.Find_Tree_Node(htree, '', ftree.find_NEXT,Ftree.NODE_LABEL,'', node);
END LOOP;
---- now you have the node number that result from search
node_val := Ftree.Get_Tree_Node_Property(htree, tree_pkg.node, Ftree.NODE_value);
-- then use this value in execute query on the supplier block
END;

Using a Heiarchical Tree with data that can be grouped

Hello Forum
I have been tasked with coming up with a selector for one of our applications that uses a tree. I have built a mock-up using the example provided at Craigs Oracle Stuff (https://sites.google.com/site/craigsoraclestuff/oracle-forms---how-to-s/forms-how-to-create-a-hierachical-tree-form) that subsuitutes our data in the SQL for his, and I have successfully added another loop as the data is located in 3 tables, but have come across a few issues. I have been searching the forums and google, but cannot find anything to solve the issues that I am having. Any help is appreciated. This is being developed in 10g. The data is structured as follows.
Category(root)
ID, Name
1, A
2, B
3, C
SubCategory (Level 2)
ID, Name, CatID
1, A, 1
2, B, 1
3, C, 1
Codes (Level 3 and beyond?)
ID SubCatID Description
1, 1, 'The, quick'
2, 1, 'The, quick, brown'
3, 1, 'The, quick, brown, fox, jumps'
4, 1, 'The, quick, brown, fox, jumps, over, the lazy, dog'
5, 2, 'Wafting, zephyrs, quickly, vexed, Jumbo'
6, 2, 'Wafting, zephyrs, quickly'
As you can see the codes table has a lot of repeating values that are delimited by ',' (commas). I can produce a tree out of the 3 tables but...
Problem:
The description in the codes table can be as many as 255 characters. The tree seems to truncate the values around 60 characters. I am not sure what the maximum data lenghts in the tree are, or if the max lengths are limited by the node or the entire tree. Although the Category and Subcategory names can be as much as 120 characters, they are more typically around 25 characters.
Could this problem be remedied buy deepeing the levels of the tree by grouping the values in the codes table on the comma delimiters? The max number of commas in the description is 9, so that would make the tree up to 11 levels deep. I know how to get the text between the commas, but am unsure how to link the data back to the parent
Ex. The tree would be
A
->A
->->The
->->->quick
->->->->brown
Thanks for any Assistance
Mike
EDIT: I found the reason that the label of the node is being limited in length. The limit is actually 50char because of this line in Craig's code in the Create_RG function:
gc_id := Add_Group_Column(rg_id, 'label', CHAR_COLUMN,50);
I changed the limit to 255 and now all of the data displays.
Although working now, I would still like to know id there is a way of grouping the data into the tree view, as this would make the tree much more readable.

hi,
In BI CONTENT,, v can just install any Object,,for that, matter,,just to make that object Active. So by Default it vll nt have any data. Install any Query data flow before and after, then select some master characteristics, and transaction data,,schedule them, Load the data,, then Ur Report Data vll display.

Hi all,
I have 2 tables.

In a box there are several items.
I want to create a hierachical tree to display items that are present in each box.

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...

Error 7343 when delete a recordin database and hierarchical tree

I got this error after delete a record and call the procedure to refresh the hierarchical tree.
This is my code:
PROCEDURE LOAD_TREE IS
htree ITEM;
rg_id RecordGroup;
errcode number;
BEGIN
rg_id := find_group('RECORD_GROUP_POPULA_TREE');
errcode := populate_group(rg_id);
-- Find the tree itself.
htree := Find_Item('HIERARCHICAL_TREE.TREE');
-- Populate the tree with data.
Ftree.Set_Tree_Property(htree, Ftree.RECORD_GROUP, rg_id);
END;
I put a code at the trigger KEY-COMMIT to refresh the hierarchical tree always the button F10 is pressed. Look:
begin
commit;
LOAD_TREE;
end;
When I insert records that´s ok...the problem is when I delete records.
Thanks!

I found the solution after read this thread: Hierachical tree delete node

Hierarchical Tree Items question, in Oracle9i forms builder ^^;

Hi,I'm kind of new to using the Hierachical Tree item in Oracle9i Forms builder. so anyway,in the book it was explaining how it's done clearly,but, what I want to do using that item is kind of different;
in the book it has the way of making it like a navigator for the items/fields/tables in the database,either by creating a view for those fields by using Select Statements or using the whole table itself.
however,what I'm trying to do is to have that tree list the names of Forms I have already created and probably the list of Reports I got,so it would sort of like a Menu and I could add a trigger to open the form/report once an item in the tree is double clicked on
here's an example of what I'm talking about :
http://i7.photobucket.com/albums/y264/_Crzy_Chck_/Htree.jpg
sorry the screen shot isn't the best ^^;
that's from a company my friend works at,they have that tree as a menu for their forms and reports,once u double click on a form name or a report,it opens up ^^;
I tried google/yahoo,I got the same info I found on the book.

Or you may want to check out this code:
   PROCEDURE next_menu(
      menu_in                                        IN OUT   NUMBER

    , node_in                                        IN       ftree.node

   END next_menu;tree_item contains the name of the tree item you are using. the select statement is based on a table that is like EMP, where one EMP van be another EMP's manager. In this table a menu-option can be another menu-option's master.
this is a recursive function that keeps calling itself untill the query finds no more record.
Good Luck!
