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.

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 ;-)))
Thanks for Help

That is not recommended. The new code editing features do not play well with an old workspace.
Please create a new workspace and import your projects into that.

How to use Oracle Help in developer 10g

Hi!
First i'm sorry for my bad english
I'm a student in computer science and i have a projet to make with Developer 10g. My teacher want us to make a Help file for the user but he don't know how to do it with developer 10g.
So i've made some research on internet and i found how to create my help file. I have downloaded Oracle Help and RoboHelp.
Using RoboHelp i've create my help file and then i generate it in Oracle Help format. I generate it in a compressed and a uncompressed version(because didn't know which one i need). So now i have two folder one who containt a .jar file and another who containt a lot of files.
What i want to know is how to execute my Oracle Help in a WHEN-BUTTON-PRESSED trigger with theses files.
Thank and sorry for my bad english

Hi Pierre,
Showing an appropriate help topic when a "Help" button is pressed in an application or when the user presses the F1 key is what we call "context-sensitive help".
In your Oracle Help help system there is an XML map file that contains topic-ids that map to help topics. You need to associate these topic-ids with your user interface (help button, etc).
Is your project an extension to JDeveloper 10g, or are you just creating a Java application using JDeveloper? If you are just using JDeveloper to create your own Java application, then you can use the CSHManager class distributed with Oracle Help for Java to enable context-sensitive help (see the Oracle Help Guide documentation). If you are creating an extension to JDeveloper, then let me know and I'll give you information on how to set up help in that context.

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.

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.

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,
Vag

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...

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).

Hierarchical Tree and keyboard navigation

Does anyone know how to use Hierarchical Trees with keyboards, or to disable keyboard actions? (forms 9.0.4)
My form has a tree which does processing in a When-Tree-Node-Selected trigger to populate some blocks depending on the selected node. If the user selects nodes with the mouse then all is fine, but if they move between nodes with the keyboard then the processing for each selected node is only run the next time a node is selected with the mouse. This means the data for each node will flash up in the blocks for a split second when the mouse is next used.
I've tried Key-Up/Key-Down triggers to prevent keyboard navigation, but they don't fire. Setting Keyboard Navigable to false doesn't fix it either.
Using the When-Tree-Node-Activated trigger doesn't help. The online help says this trigger fires when the user presses Enter or double-clicks a node. I find that each node for which Enter was pressed is processed only when the user next double-clicks a node, and the node they double-click is not processed.
Tree Query:select 1, level, ename, null, null

Hi James,
We have got the same problem, after searching Metalink I found that this is a known bug. See Metalink Bug no 4565623 (base bug 4509399).

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
saji daniel

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 control

Dear all,
Any body send me hints or sample codes about using Hierarchical tree control in forms

Type that into google and you should get some stuff. The biggest thing to remember is the query MUST have (presuming you are populating a tree from a db) certain values.
Check out this dicussion which I started when I was learning: Re: Creating a menu system (not a file menu)

Hierarchical Trees: Creating and populating

How would I go about it if was to have hierarchical trees and populate them with dynamic data that changes at runtime with the occurence of an event such as clicking of a button?
I use Forms version 6.0.8.8.0.

Did you read the documentation? It explains how to use hierarchical trees.
