Help on adding a node to a tree

Hi All,
I need help on hierarchical trees.
I am running forms 6i on oracle 9i. I am trying to create an organizational chart using the hierarchical tree.
I create an initial tree based on a record group, with two . I want to add a node to the last node but I cant see it anytime I try. I mean if my tree looks like
+ (Parent_1)
|
(Child_1_of_Parent_1)
As indicated, I want to add a node which will be a child of Child_1_of_Parent_1, but I have not been able to. I can add a node as a child of Parent_1 using the Add_Tree_Node but not Child_1_of_Parent_1.
Can any one help, I want to build the chart on the screen so I will prefer the use of the Ftree built-in to add nodes as opposed to populating the tree from a record group.
I will appreciate any help.
Thanks in advance.

Hi All,
Could some one please help me out on this, its urgent.
Pls help.

Help on adding adding a node to a tree

Hi all,
I am compelled to re-post this thread because I still haven't received any help yet.
Could someone please help me out, its urgent.
I am developing in Forms 6i with Oracle 9i.
I am trying to build an organizational chart. I use a non-query record group to populate the first two nodes of the tree. The other nodes I want to add from the screen. I am able to add to the parent node with the Add_Tree_Node function of the Ftree package, but I am not able to add to the second node. To illustrate I have something in the form shown below:
- Parent
|
|_ Child1
I can add Child2 to Parent, but I want to add GrandChild1 to Child1 so I get something in the form below:
- Parent
|
|_ Child1
|
|_ GrandChild1
Please help.

Could you please post your code?
Below code is working fine for me....
declare
     rg_id recordgroup;
     col_id1 groupcolumn;

Adding JTree nodes from worker threads

I'm trying to add a large number of nodes (> 1700) to a JTree, and I'm looking for a way to do this while allowing the user to continue working in the meantime.
The nodes are retrieved from a database, which may be geographically distant and therefore possibly slow to access. I would like to have the process of processing the result-set and creating the Nodes run separately.
I have considered processing the result-set in a separate Thread and creating the Nodes before then returning to the EDT to add them to the tree. This would cause the GUI to pause when adding the Nodes to the tree, but does at least separate the DB access out of the EDT.
I would prefer to update the tree node by node as the result-set is processed, but I'm not sure whether this would incur too much overhead.
I would appreciate any advice.

I'm not sure overhead is the problemimport java.awt.*;

Adding 2 icons for a single node on a tree

Hi,
I am trying to create a tree to represent objects. These objects can be of different types, and different states. I intend to use two icons for each node in the tree, one signifying the type and the other the status. I am a bit stuck though.
At present each node has a single icon, and uses a JLabel to add to the tree (with a custom renderer). Is it possible to manipulate the icons so instead of adding 2 16x16icons I can simplify it by adding a 32x16 icon?
Alternativley is it possible to customise JLabel (or something) to allow two icons to be added and alligned?
Cheers in advance
Chris

Just write your own composite Icon class:
public class CompositeIcon implements Icon
private Icon icon1;
private Icon icon2;
public CompositeIcon(Icon icon1, Icon icon2)
    this.icon1 = icon1;
    this.icon2 = icon2;
public int getIconHeight()
    return Math.max(icon1.getIconHeight(), icon2.getIconHeight());
public int getIconWidth()
    return icon1.getIconWidth() + icon2.getIconWidth();
public void paintIcon(Component c, Graphics g, int x, int y)
    icon1.paintIcon(c, g, x, y);
    icon2.paintIcon(c, g, x + icon1.getIconWidth, y);
}Hopefully a slightly more reusable solution. You could write all sorts of different layouts in this way.
Hope this helps.

Get All Nodes in a tree

Can somebody tell me how to get all the node objects (DefaultMutableTreeNode) that are there in JTree?
Suppose I have created a tree and added 4 nodes to the same, and if I want to get dynamically all the nodes that are there in the tree, what should I do?
Please help me..as it is urgent
Thanx in Advance
Novi

If you check the documentation to DefaultMutableTreeNode you see that some methods return enumerations, for example postorderEnumeration. You can use these to traverse the tree,
DefaultMutableTreeNode root = ....;         // start node.
Enumeration e = root.postorderEnumeration(); // get wanted enumeration
while (e.hasMoreElements()) {                // all nodes
   DefaultMutableTreeNode node =
      (DefaultMutableTreeNode)e.nextElement(); // get node
   // do something with the node
}PS. The code compiles but I havent actually run it :(

Select the multiple nodes in a tree

Hi Experts,
We need to select the multiple nodes in a tree.Whatever we are selecting,that has to be added in the table as a tree structure itself.
For ex:
A
|--A1
|--B1
If We select the A then A,A1 and B1 has to be added in a table.Please help me out for this.

Adding image for the selected Tree leaf???

Hi All,
         I am working with flex tree component in which i have to add
an arrow image for the selected leaf node. I tried to do this using itemclick event
but cant make it. can you help me out in doing this???
Note: I have written custom Tree and TreeItemRenderer...
-Sundar

Thanks for ur reply Grizzzzzzzzz,
                                                is there a way to identify the selected leaf from within MyTreeItemRenderer(Extends TreeItemRenderer)?
                                               If this is possible,i can add the image to the selected leaf of the tree.
Right now i am assigning images to all the leaf nodes of the tree as follows:
public
class MyTreeItemRenderer extends TreeItemRenderer
* Override to draw a line in case current item is a leaf.
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):
void{
// Call super method
super.updateDisplayList(unscaledWidth, unscaledHeight);
if(super.data){
if(TreeListData(super.listData).hasChildren){
// logic for parent node comes here
else{
//Adding leaf Image
//Logic to add images to leaf
myImage.source = leafImage;
myImage.x =
super.label.x;
//The above code adds images to all leaf nodes. CAN I ADD THIS IMAGE ONLY TO THE SELECTED LEAF NODE???
//HOW TO FIND THE SELECTED LEAF NODE FROM HERE??? SO THAT SELECTED LEAF WILL BE ADDED WITH THE IMAGE???
//The above code adds images to all leaf nodes. CAN I ADD THIS IMAGE ONLY TO THE SELECTED LEAF NODE???

Need help to read model node input field attribute present in view - first time developer.

Hello Experts,
I am new to CRM Web UI development.
Presently, I am trying to develop a Guided Activity Page having 2 views.
First view has the field Business Partner Number, I have added model Node BuilHeader and the attribute BP_NUMBER while creation of the view.
The Second View consists of 2 fields from the Model Node BuilHeader, namely First Name and Last Name.
The requirement is to enter the BP Number on the first screen then click on the NEXT button from the Guided Activity buttons, on navigating to the Second View, the Names should auto-populate.
I have Created both views and the GP page, the GP navigation is also happening. Initially the fields were showing Not Bound text in value, so I commented the line in GET_I and GET methods to enable the field and remove the Not Bound text. I have created a custom controller with BuilHeader
I have tried doing this but facing the below problems :
1) When I enter the BP number on the first view and press Enter, the value disappears. How to solve this ?
2) Does clicking on the NEXT button on the GP Navigation trigger a Server Roundtrip ?
3) How to read the context node value of BP Number entered on the first view and populate the Name fields on the second view.
Please help.........

you can take reference from from below code as in above case we use BuilHeaderAdvancedSearch search object, to get current entity.
data: query TYPE REF TO cl_crm_bol_dquery_service,.
query ?= me->typed_context->BuilHeaderAdvancedSearch->collection_wrapper->get_current( ).
Do not remove code from getter setter of fields , it will not clear.
Check with http://scn.sap.com/thread/3391203 , for basic understanding of UI.

How to not display nodes in a tree if Oracle roles are NOT used?

How to not display nodes in a tree if Oracle roles are NOT used?
We don't use Oracle DB roles to grant users access to Forms from the menu. We use a template and role system of our own. Basically a few tables with templates and roles.
We want to convert our normal Forms menu to a tree menu and one of our key requirements is that when the tree is populated ONLY nodes with programs (i.e. forms) he has been granted to execute is shown.
Since we don't use Oracle Roles how to do this in a tree?
I created a function to show/hide LEAF nodes, BUT problem is that there are sub-menu nodes showing even if the leaf-nodes under it has not being displayed. My function has suppressed it.
My tree query is like this:
SELECT
     t.status, LEVEL, t.label, t.icon, t.node VALUE
FROM
     tma_tree_menu t
WHERE
tma_authenticate_sys_chk_role(USER, t.node) = 1
CONNECT BY
     PRIOR t.node = t.master
START WITH
     t.MASTER IS NULL
ORDER SIBLINGS BY
t.position
The tma_authenticate_sys_chk_role will return 1 only if the user has access to the form under that node.
I tried the FTree functions in Forms but even that has nothing.
Any help would be greatly appreciated.

Would you share the source code? I guess what I need is how exactly you retreive the user credentials from the DB table and set that boolean variable.
and then how to condition it in UIX?

The document references posted already are very good ones. However, I would say that on personal experience (on Solaris and 10gR2) that the addnode tools gave me nothing but problems. Luckily, I was able to build a parallel cluster (with three nodes) on other hardware and then move the databases across via DataGuard. It was quicker and cleaner (and easier!) that way...
Good luck!

How can I get the previous clicked node in a Tree?

I have a JTree. If a node is selected, before the user select another, I need to make a question if he have sure about the new selection.
If the user answers not, I need to select the previous node.
I have in my class a variable, type of DefaultMutableTreeNode, that makes reference to the last node selected.
How can I turn this node selected again, if the user select "No"?
Thanks for any help.
Renato de Melo

You don't want to maintain a reference to the last selected node, but to the last selected path. Nodes within a tree are addressed using a TreePath, with contains references to each node from the root, down to a specific node. Look at the JavaDocs of javax.swing.tree.TreePath for more info.
Also, JTree has getter/setter methods for the selectionPath.
