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
<?xml version="1.0" encoding="UTF-8" ?>
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel" version="11.1.2.60.17" id="categoryPageDef"

Drop on a Tree Node - Help!

On a drop on a tree node, I'd like to get the item that is
being dropped on.
Tree object being dropped on: event.currentTarget
Index of node in tree being dropped on:
event.currentTarget..calculateDropIndex(event); where event is the
DragEvent
dropTarget is a great name for a method that would do this,
but it returns a display object.
Some ideas:
1. Use the index to somehow go through the XML data provider.
I don't think this is the right way - the XML structure is not list
based.
2. The Tree creates a list from the XML. How can I leverage
that and get the item for a given node index? dropTarget seems like
the right term, but it returns a display object.
3. tree.selectedItem and tree.Selected Items return null and
an array of null, so I can't use that either.

Hello Brian,
thanks for your reply.
The benefit of focusing a node in the tree is the following:
If a person only uses the keyboard to navigate (e.g. because of him/her being blind) expands a tree node, he expects the focus still being on the expanded tree node afterwards. But if a roundtrip to the server happens (because of a executed onClick-event) the focus after the reload is at the beginning of the page again. Thus the blind person hast to TAB through the whole page again until he reaches the tree node he has expanded.
I use the com.sapportals.htmlb.* package for the htmlb-elements.
Almost all elements are underclasses of com.sapportals.htmlb.Component, but Treenode is not.
I use a model to create tree nodes. TreeNodes are created like this in the Model:
mComponentsNode = new TreeNode(COMP_NODE_ID);
mComponentsNode.setComponent(new TextView(COMP_NODE_TEXT));
mComponentsNode.setOnNodeClick(MODE_ON_CLICK_EVENT);
mComponentsNode.setOnNodeExpand(TREE_NODE_EXPAND_EVENT);
mComponentsNode.setOnNodeClose(TREE_NODE_CLOSE_EVENT);
mComponentsNode.setTooltip(COMP_NODE_TOOLTIP);
mComponentsNode.setOpen(true);
mHomeNode.addChildNode(mComponentsNode);
In the JSP the tree is created like this:
<hbj:tree id="configTree"
    title=""
    rootNode="configTree"
    rootNodeIsVisible="false">
</tree>
Do you have any idea?
Thanks!

Bastian

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;

Help with building a JTree using tree node and node renderers

Hi,
I am having a few problems with JTree's. basically I want to build JTree from a web spider. The webspide searches a website checking links and stores the current url that is being processed as a string in the variable msg. I wan to use this variable to build a JTree in a new class and then add it to my GUI. I have created a tree node class and a renderer node class, these classes are built fine. can someone point me in the direction for actually using these to build my tree in a seperate class and then displaying it in a GUI class?

I beleive that this line of code is required:
treeText.addObject(msgInfo);
I have placed it where the action events start the spider, but i keep getting this error:
cannot resolve symbol
symbol : method addObject (java.lang.String)
location: class javax.swing.JTextArea
treeText.addObject(msgInfo);
Also the jtree is not showing the window that I want it to and I am not too sure why. could you have a look to see why? i think it needs a fresh pair of eyes.
Many thanks

Help w/ clicking on leaves of tree node

Hello,
I am fairly new to Flex and coding in general, so please bare
with me if my problems seems like a trivial one.
I am trying to create a tree list, where the contents of the
tree are actually links. For example, the top level of the tree
node would be a category (companies), and the leaves of the tree
would be the company names. In addition, I would like the user to
be taken, in a new browser window, to a URL specified in the XML
list when clicking on a company name.
I am having problems resolving the click actions in the app.
I can get the app to open and close the nodes of the tree cleanly,
but when I try to add some code to take the user to a URL when
clicking on a company name (leaf), I get errors.
I am really stuck on how to read the click event in the tree
list, run to the associated XML file to find the URL, then open up
a new browser page to that URL.
Can someone help me please? I've added a snippet of code to
review.
Thank you in advance!

Two things:
1) I'm thinking the currentTarget of the itemClick event will
be the tree
itself, not the node. So you need to look at the selectedItem
property to
get the node. See the example under Handling Tree control
events:
http://livedocs.adobe.com/flex/3/html/help.html?content=dpcontrols_8.html
2) To answer your question, you just need to reference it
properly for
however you set up the xml:

SAP has provided a lot of sample programs for developing tree structures. Just go to SE38, type BCALVTREE and hit F4. You'll get different sample programs with a range of operations on trees
Go through the link,

I recently used an external hard drive to back up photos etc from my mac, I didn't do a full system back up. Since then a finder window titled 'client node' keeps popping up every time i hit the spacebar. Can anyone help me please stop this happening?

I recently used an external hard drive to back up photos etc from my mac, I didn't do a full system back up. Since then a finder window titled 'client node' keeps popping up every time i hit the spacebar. Can anyone help me please stop this happening?

Click on it, choose Get Info from the File menu, and check the format.
If it's formatted as NTFS, reformat it as MS-DOS, exFAT, or Mac OS Extended (Journaled) as desired, or install software such as Paragon NTFS on the computer.
If it's formatted as FAT32 or exFAT, use the Disk Utility's Repair Disk command on it; this may also happen for a flash drive which is about to fail.
If it's formatted as Mac OS Extended, click Authenticate and provide your administrator password, or change the permissions on that specific folder in its Get Info window.

Creation of a Popup Menu for a Tree Node

Hi Ppl,
I need to create a Pop-up Menu for a tree node in WebDynpro Application, please give me a "How to .." sort of material or a link which would have same sort of information...
Also, My requirement is to call the pop-up on the right click of mouse on the tree node, please let me know on which event handler I can call it ? Do I require a custom event handler for it ?
Thanks in advance
Anish

Hi Anish,
You simply add a Tree UI element, and then right-click the tree UI element and insert a TreeNode element.
To the TreeNode element you can add a menu, and then to this menu you can add menu items. When the user right click the tree node, the menu item is displayed. If the user clicks the menu item, the action for the menuitem is run.
Hope that helps.

But
If i create .jspx page From
Web Tier->Jsp->page Then it is working fine
when i create .jspx page From
Web Tier->JSF\Facelets->page Then it is not working
i need to get value from "Web Tier->JSF\Facelets->page"
is there any help please?

You should try Franks generic selectionListener http://www.oracle.com/technetwork/developer-tools/adf/learnmore/25-generic-tree-selection-listener-169164.pdf. For help on hoe to get the selected tree node data check http://www.oracle.com/technetwork/developer-tools/adf/learnmore/26-get-selected-tree-node-data-169165.pdf

Custom tree node and DefaultTreeModel

Hello,
I would like to know if it's possible to use the following custom tree node with the DefaultTreeModel:
class MyTreeNode extends DefaultMutableTreeNode{
private String _argument = null;
public MyTreeNode(){}
public MyTreeNode(Object node, String argument){
     super(node);
      _argument = argument;
}I have tried it and it's not working but I think in theory it should work. Please correct me if I'm wrong.
The problem is that the tree won't display or insert the custom node when the insertNodeAt(...) method of
the DefaultTreeModel is called. I also tried using a custom tree listener and calling the .reload() method directly.
Any help will be very appreciated.
Thanks in advanced.

Are you sure it's not being inserted into the model,
and just not being displayed?
Are you calling nodesWereInserted() after your
insertion?Thanks for your reply.
I've modified my app. so that the following method will populate the tree for testing only:
public void populateTree()
    MyTreeNode root = new MyTreeNode("Root Node", "test");
    DefaultTreeModel treeModel = new DefaultTreeModel(root);
    JTree tree = new JTree(treeModel);
    tree.setEditable(true);
    tree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
    tree.setShowsRootHandles(true);
    JScrollPane scrollPane = new JScrollPane(tree);
    setLayout(new GridLayout(1,0));
    add(scrollPane);
    int childIdx[] = {0,1};
    String p1Name = new String("Parent 1");
    String p2Name = new String("Parent 2");
    String c1Name = new String("Child 1");
    String c2Name = new String("Child 2");
    MyTreeNode p1 = new MyTreeNode(p1Name, "test");
    MyTreeNode p2 = new MyTreeNode(p2Name, "test");
    MyTreeNode c1 = new MyTreeNode(c1Name, "test");
    MyTreeNode c2 = new MyTreeNode(c2Name, "test");
    treeModel.insertNodeInto(p1, root, 0);
    treeModel.insertNodeInto(p2, root, 1);
    treeModel.nodesWereInserted(root, childIdx);
    treeModel.insertNodeInto(c1, p1, 0);
    treeModel.insertNodeInto(c2, p1, 1);
    treeModel.nodesWereInserted(p1, childIdx);
    treeModel.reload();
}And the result is that the "Root Node" will be displayed with "Parent1" and "Parent2" but "Parent1" won't have any children. Furthermore, if I try to remove "Parent1" using:
treeModel.removeNodeFromParent(p1);I will get an exception saying that node p1 has no parent, which suggests that the parent/child relation
is not being assigned by the model, even though the nodes (p1, p2) are displayed in the tree showing "Root node" as the parent. This is very strange.
Please help.

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.

TRY.
          lv_child = me->node_factory->get_proxy(
                    iv_bo = lv_value_node
                    iv_parent_proxy = me
                    iv_proxy_type = 'ZL_CLASS_CN02' ).
          lv_child->is_leaf = 'X'.
          APPEND lv_child TO rt_children.
        CATCH cx_sy_move_cast_error cx_sy_ref_is_initial.
      ENDTRY.
In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data. After/before this, you would need to build table and refresh in do-prepare_output of IMPL class.In the above code iv_bo , lv_value_node will be the actual object of the second node or leaf node here, which will have the same structure of parent node along with data.

ztyped_context->resultlist->build_table( ).
IF ztyped_context->resultlist->node_tab IS INITIAL.
    ztyped_context->resultlist->refresh( ).
ENDIF.
Also the EH_ONEXPAND has to be implemented and event handled in DO_HANDLE_EVENT. But this expand event has to be delegated to context node directly as CL_BSP_WD_CONTEXT_NODE_TREE will already have the implementation.
ztyped_context->resultlist->expand_node( lv_event->row_key ).
Where in result list is the node ZL_CLASS_CN00.
After typing the whole content , i found this blog :). There are few things i have written more that in the blog. /people/poonam.assudani/blog/2009/06/24/create-a-tree-view-display-in-crm-web-ui

Tree node icon from XML

Is there a way to define a linkage id to set the icon for the
tree component in external XML? This is what I tried and it does
not work.
<node label="Test" data="SomeID" icon="SomeLinkageID">
The tree node is using the default folder icon. I know I
could set the icon after it is loaded but why cann't I just throw
in something to define the icon in the XML?
Thanks
