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 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 through 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? I use forms 6i.
Thank you in advance,
Vag

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

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...

go_block('block3');
EXECUTE_QUERY;
exception
     when e_child_rec then
          Message ('Go Kimi Go');
end;
Now when i double click the mouse its show tree icon
I want when i run my module its show me all node icon
Hope this time i clear my question

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.

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

Tree node edit

First, sorry for my English.
It is necessary to rename a treenode by selecting of a
menuitem from the contextual menu like to rename folder in Windows
explorer.
Did so:
1.) Last used treenode:
(- Tree in MXML)
<mx:Tree id="computerTree" width="100%" height="100%"
labelField="@label" showRoot="true"
dataProvider="{treeData}"
contextMenu="{treeMenu}"
itemRollOver="SetLastTreeItem(event)"
editable="false"
itemEditBeginning="Tree_itemEditBeginning(event)"/>
(- in ActionScript)
public function SetLastTreeItem(event:ListEvent):void
lastTreeItem = event.itemRenderer.data as XML;
2.) eventListener when ContextMenu item "rename" selected:
public function
ContextMenu_SelectItemRename(event:ContextMenuEvent):void
var y:int;
y=computerTree.getItemIndex(lastTreeItem);
tree.editedItemPosition={columnIndex:0, rowIndex:y};
tree.createItemEditor(0,y);
But that didn't work:
- itemEditor appears in necessary position, but empty.
- When itemEditor is closed there is an error in List.as.
(TypeError: Error #1009: Cannot access a property or method
of a null object reference.
at
mx.controls::List/endEdit()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\controls\Li st.as:2174]
at
mx.controls::List/editorKeyDownHandler()[E:\dev\3.0.x\frameworks\projects\framework\src\m x\controls\List.as:2444])
May be someone knows the ways to rename a treenode by
selecting of a menuitem from the contextual menu, not by
mouseClick?
In adobe manual I has read:
"To create an editor at other times, set the
editedItemPosition property to generate the itemEditBegin event"
But this event does not come.

Add/Edit/Delete Tree Nodes using CL_GUI_ALV_TREE

Hi All,
I am looking for an example of program with CL_GUI_ALV_TREE that have a functionality of add a tree node, edit a tree node, and delete a tree node.
I have already looked the BCALV_TREE* demo program but could not able to find a program to add/edit/delete node tree elements.
Any info on this.
Thanks
aRs

Hello aRs
Here is a sample report showing how to delete nodes in an ALV tree. The report was copied from BCALV_TREE_01. Search for added code:
*$ADDED: begin
*$ADDED: end[/code]
When you display the tree expand the first folder completely. When entering 'DELETE' into the command field directly the first flight date node will be deleted.
REPORT ZUS_SDN_BCALV_TREE_01_DELNODE.
based on: REPORT bcalv_tree_01.
Purpose:
~~~~~~~~
This report shows the essential steps to build up a hierarchy
using an ALV Tree Control (class CL_GUI_ALV_TREE).
Note that it is not possible to build up this hierarchy
using a simple ALV Tree Control (class CL_GUI_ALV_TREE_SIMPLE).
To check program behavior
~~~~~~~~~~~~~~~~~~~~~~~~~
Start this report. The hierarchy tree consists of nodes for each
month on top level (this level can not be build by a simple ALV Tree
because there is no field for months in our output table SFLIGHT.
Thus, you can not define this hierarchy by sorting).
Nor initial calculations neither a special layout has been applied
(the lines on the right do not show anything).
Note also that this example does not build up and change the
fieldcatalog of the output table. For this reason, all fields
of the output table are shown in the columns although the fields
CARRID and FLDATE are already placed in the tree on the left.
(Of course, this is not a good style. See BCALV_TREE_02 on how to
hide columns).

himself.

only be used for one ALV Tree Control.

How to make a node of a Hierarchical Tree BOLD

When we click the node of a Hierarchical Tree, we want to make the node BOLD. We tried using set item property but it's not working.

There aren't really any built-ins that will allow you to change the Font Weight of the Tree Node Label. You might be able to accomplish this with Java, but you would have to write your own Java Bean to implement. It might be easier to simply add an Asterisk (*) to the label programatically using the Set-Tree-Node-Property() built-in, but this presents problems with removing the asterisk when you leave the selected node or select a new node. It can be resolved, but you'll have to record all the information you'll need to reset the node - namly just the Node_ID.
Hope this helps,
Craig B-)

JTreeTable problem editing tree node

Hi,
Iam using the swing JTreeTable component and facing a problem. Iam displaying hierarchical data in the JTreeTable. Now I would like to provide the facility to edit a tree node. I have a TreeSelectionListener registered on the tree and a TreeModelListener registered on the DefaultTreeModel. Wheneve, I start editing a node by double clicking it the valueChanged method is called but I do not see the new value the user types in this method. I have another method setValueAt which is where I can see the new value the user has entered.
I can set this new value to the treenode using
node.setUserObject(newValue);However, if I do this, the next time I try to edit the same node, the editor component is painted over the tree node thus displaying an empty textfield that occupies the entire cell.
How can I make the editor appear above the tree node with the contents loaded in it always.
Any help is appreciated.
cheers,
vidyut

You bind a mouselistener to the tree, so it has to be handled there.
When clicking once (method should be "mouseReleased" or something, treenodes name (toString) should be .setText("");

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;
END;

How-to synchronize edit forms for a single View Object tree node entrie

Hi all,
I created a tree from a single View Object,
follow this [http://www.oracle.com/technetwork/developer-tools/adf/learnmore/32-tree-table-from-single-vo-169174.pdf]
then i want to create and synchronize edit forms for tree node entries,
follow this [http://www.oracle.com/technetwork/developer-tools/adf/learnmore/50-synchromize-form-treeselection-169192.pdf]
but it not working when i click child node!!
i found the latter tree from many View Object ,but the former tree from single View Object.
what should i do?
Thanks in advance

Hi,
say the tree is built from ViewObject1. In the AM model, create a second View Object instance for this. Say ViewObject2. Create the form from ViewObject2 and the tree from ViewObject1. When creating the tree, use the"Target Data Source" option at the bottom to reference the iterator of ViewObject2. Then create a PartialTrigger on the paneFormLayout that holds the synch form. In the partial trigger property, reference the tree so that when the tree selection changes, the form is updated. Then create a PartialTrigger property on the tree and point it to the submit button of the form so you can show updated values in the tree.
