Hierarchical Tree Node Attributes

Hi,
I know that Oracle' official answer to this is no, but is there a way to specify attributes for specific nodes in a hierarchical tree? I would like to display specific nodes in bold and specific nodes in a different color.
Any idea welcomed.
Monica

If this were possible then you would have to use the FTree package and probably the FTree.Set_Tree_Node_Property procedure, so check those in the help system. But I'm 99.99% sure you'd be wasting your time.
You might be able to do it with a JTree in a bean (it looks like it's not possible to extend an htree item in a pjc) but in forms the best you can do is assign icons to the nodes.

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.

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

Hierarchical tree node problem

Hi all --
Today's problem is (drum roll)............
My application uses a heirarichal tree where each tree node contains the name of a form within this system. The user can navigate from form to form by clicking the appropriatetly name tree node. This seems to work - sometimes. Some users click on a node for one form, but get transferred to another named form(usually the one above or below the one actually activated). I've also found out that this happens ONLY when the user has their screen resolution set to 800 x 600. This application was developed at screen resolution 1024 x 768 and it woks fine. Anybody know why??

Here is the code for both the tree node selected and tree node activated triggers

Hierarchical tree node editable

hi,
is there a property to make a tree node label editable? it would be kind to click on the label, change it and save to DB, instead of copying its value into a text field.
thanks

Not directly as Andreas said but alternately you can do by
You can set the label of NODE and update into the BASE table block and re-populate the tree
- on Double click the label call custom Stack canvas contains new label in text item and user will press OK
- Sets the Label of the Tree node
- Update the new label to the base table block
- Commit and re-populate the tree
if responses are helpful or correct please mark 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;

     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

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. : (

Problem when selecting child node in Hierarchical Tree

I have a hierarchical tree on a form populated thru a table query(form1). When I click on a child node, it opens form2 which contains a tab canvas. After closing forms, I return to the form1(containing Tree). At this point If I want to click on the same child node, I should be able to open form2 again. This doesn't happen.
I have the following code in my When-Tree-node_selected trigger:
Declare
htree item;
vnode_label varchar2(50);
node_clicked FTREE.NODE;
vnode_value number;
vnode_depth number;
v_type number;
v_value varchar2(100);
v_form_name varchar2(100);
v_alert_return number;
begin
-- Find the tree itself.
htree := FIND_ITEM('tree_block.tree');
node_clicked := :SYSTEM.TRIGGER_NODE;
vnode_value := FTREE.NODE_label;
-- Find the value of the node clicked on.
vnode_label := FTREE.GET_TREE_NODE_PROPERTY (htree,:SYSTEM.TRIGGER_NODE,FTREE.NODE_label);
vnode_depth := to_number(ftree.get_tree_node_property(htree,:SYSTEM.TRIGGER_NODE,ftree.Node_depth));
--Open form for node selected on tree and/or specific tab page
if vnode_depth <> 1 then
if :system.trigger_node_selected = 'TRUE' then CASE vnode_label
WHEN 'Personal' then
v_form_name :='HR_PERSONAL_INFO_UPDATE';
WHEN 'Citizenship' then
v_form_name :='HR_PERSONAL_INFO_UPDATE';

if id_null(Find_form(v_form_name)) then
open_form(:global.application_path || v_form_name,ACTIVATE,NO_SESSION,SHARE_LIBRARY_DATA);
else
go_form(v_form_name);
end if;
END IF;
elsif vnode_depth = 1 then
if :system.trigger_node_SELECTED = 'TRUE' then CASE vnode_label
WHEN 'EMPLOYEE INFO' then
v_form_name :='HR_PERSONAL_INFO_UPDATE';
vnode_label := 'Personal';
WHEN 'REPORTS' then
v_form_name :='HR_REPORTS';
vnode_label := '';
if id_null(Find_form(v_form_name)) then
v_form_name := :global.application_path || v_form_name;
open_form(v_form_name,ACTIVATE,NO_SESSION,SHARE_LIBRARY_DATA);--,p_list);
else
go_form(v_form_name);
end if;
end if;
end;
Can anyone please help me? I don't want the user to double click. They should only click once.
Thanks,
Mercedes

Right clicking does not change the current selection. The tree has no way to report what node was right clicked. Only work around is to left click the node you wish then right click it.

Hierarchical tree with iconic nodes

hi i'm using database - 10g, developer suite - 10g; created a hierarchical tree and the icons are displaying along side the nodes when they are being selected or activated.
problem - i've stored the icons in g:\ICONS (all gif icons). but when i run the form it is picking up the icons from the following location - C:\Documents and Settings\development\Oracle Jar Cache\frmall_jinit.jar-63ace618-1160d49b\oracle\forms\icons. I've a button in the same form and the icon showing on it is from the location G:\ICONS(as desired); but in case of tree it's from the location which is not desirable.
any help.

Hello,
You need to change the imagebase parameter to be documentbase instead of codebase.
When imagebase is set to codebase forms looks for Images in the jar files and then in the absolute path, otherwise it check direct path.
For details in deploying the Images please check:
http://docs.oracle.com/cd/B14099_19/web.1012/b14032/configure009.htm
Clear the Java cache and browser cache after the above changes!

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 :)
