JTree - Create nodes and expand

Hi there,
I have made a file-tree from the swing jtree, where My Computer is the root, then C:/ etc, Program Files, etc...
The problem I'm having is that I'm trying to open up a node if a link has been clicked. For example.. if A shortcut to C:/Program Files/Pictures/pic.jpg was clicked, then it should go the C:/ node, create it's children, and expand it, go to Program Files node, create it's children and expand it, etc until pic.jpg is visible.
TreePath x = new TreePath(ta);
TreePath y = x.pathByAddingChild(myComputer);
TreePath z = y.pathByAddingChild(programFiles);
tree.expandPath(y);
The above is the general idea of what I'm trying... I can't see why this doesn't work. (ta is empty root folder, then myComputer and programFiles are other treenodes).
Any ideas?
Thanks.
David

Create your TreeModel using the FileSystem as the underlying data store, as shown in this article:
http://java.sun.com/products/jfc/tsc/articles/jtree/
The use JTree#setAnchorSelectionPath when the user clicks on a file to select that item in the tree. Also look at JTree#scrollPathToVisible if your JTree is in a scroll pane.

Hi All,
i create a tree and implement a TreeSelectionListener:
my mission is whenever i select a node i need to change the icon of this node (for now.later i will have to find if it have childrens).

when i select a node the the method "getTreeCellRendererComponent"
start to run on the entire tree from buttom to top and than from top to buttom.
for me it waste of time because if has say 100 nodes it wont botthers me.
but i have 20000 nodes and more its take a time.
and for all this nodes i have to make compares.
is there a way to force the DefaultTreeCellRenderer to not run the entire tree???
Thanks

You need to make sure that your TreeModel interprets your group nodes to be non-leaf nodes (one of the methods in the TreeModel interface is called isLeaf). If you are using a DefaultTreeModel with DefaultMutableTreeNode objects, you can use the askAllowsChildren property of DefaultTreeModel and the allowsChildren property of DefaultMutableTreeNode to control this. See the API for more details:
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/tree/DefaultTreeModel.html

Collapse top node and expand below node

Hi,
In my Query, I have inserted a characteristic2 below an existing characteristic1(like a hierarchy). The problem I m facing is that if I set "Collapse node" property in the top characteristic(Characteristic1) it is also applied to the below characteristic(Characteristic 2). I want the characteristic 1 to be collapsed by default and characteristic 2 to be expanded by default. Is this possible?
Regards,
Krishna

Hi
I hope your requirement is not possible.Be coz char 2 will be dependent on Char1.When u collapse Char1 automaticall Char2 also collapsed.

Adding Node and Deleting Node in Tree

Hi,
I am building a tree dynamically.
I have a class which has set of properties.I am constructing as follows.
public class TreeNode
        public function TreeNode()
     public var friendlyName:String;
     public var icon:Class;
     [Bindable]
     public var children : Array;
     public var logicalName:String;
     public var neType:String;
     [Bindable]
     public var arrayColl:ArrayCollection = new ArrayCollection();
     public function addChild(node:TopoTreeNode):void
         if (this.children == null){
             this.children = new Array();
         children.push(node);
         arrayColl.source = children;
     public function clearChild():void
         children = null;
     public function removeChild(arrayIndex:int):void
         if(children != null)
         children.splice(arrayIndex,1);
         arrayColl.source = children;
Then I set the dataProvider as follows where treeModel is object that is injected.
<mx:Tree id="tree"
             dataProvider="{treeModel.rootNode.arrayColl}"
             labelFunction="{treeModel.getDisplayName}"
             iconFunction="{treeModel.setIcon}"
             width="100%"
             height="95%"
             rowCount="6"
             showScrollTips="true" showDataTips="true" dataTipFunction="{treeModel.getDisplayName}" allowMultipleSelection="true" click="treeModel.displayItemInWorkingView(tree.selectedItems);"/>
TreeModel has the following variables
        [Bindable]
        public var rootNode:TopoTreeNode = new TopoTreeNode(); // this is the rootNode.
        [Bindable]
        public var rootChild:TopoTreeNode = new TopoTreeNode(); // this is the child of the root node..
While constructing the tree, it is working fine.
But after this when i try to add a node (ie adding a node as child to rootNode), it is getting added to my rootNode object but it is not getting displayed
When i click on the items in the tree or click on the drop menu in the tree it is getting displayed.
But i want it to be shown in the tree without clicking anything.
Could anyone help on this?
Regards
Srini

Off the top of my head, you need to call a refresh of some sort, or executeBindings()... something like that.
You will also need to start at the root node and expand any parent branches down to the new leaf.
If you are still having trouble after looking into that, I can try and dig through some of old code and find my solution.

Hi ganesh,
you have two options to get it working.
The first one is using a CanonicalEditPolicy, which creates all Nodes and Edges for you based on your semantic model. This is easy to implement, but it has some drawbacks. Your editor will get dirty after opening it, because your Notation Model is changes and no layout information is available.
The better way is to create Nodes and Edges for each semantic element you created.
For your code snippet it might look like this:
XXX model = createInitialModel();
YYY yyy = XXXFactory.eINSTANCE.createYYY();
yyy.setAttribute1("2");
yyy.setAttribute2("name");
model.getYYYs().add(yyy);
attachModelToResource(model, modelResource);
Diagram diagram = ViewService.createDiagram(model, XXXEditPart.MODEL_ID,XXXEditorPlugin.DIAGRAM_PREFERENCES_HINT);
Node yyyView = ViewService.createNode(diagram, yyy, SemanticHints.YYY,
,XXXEditorPlugin.DIAGRAM_PREFERENCES_HINT);
//Set some layout information assuming you use a XYLayout
Bounds bounds = NotationFactory.eINSTANCE.createBounds();
bounds.setX(70);
bounds.setY(20);
yyyView.setLayoutConstraint(bounds);

Andreas

Creating Diagram and model file programmatically

Hi,
Am trying to create the Diagram and model file programmatically.
I used the code similar to what is there in XXDiagramEditorUtil.createDiagram().
In the normal case (when i have an empty domain ie nothing is set into the domain object), the diagram and the domain file gets created and works fine.
Assume my model is of type XX, and that has a list of YY.
i create YY and set it inside XX.
Now when i create the domain file, the <YY> is set correctly inside <XX>.
But in the diagram file, i dont see the <children/> tags corresponding to the YY.
How would the appropriate <children/> tags be generated ?
i tried diagram.createChild(yy.eClass()), but the diagram file does not get generated.
Pls help.
AbstractTransactionalCommand command = new AbstractTransactionalCommand(editingDomain,
Messages.XXXDiagramEditorUtil_CreateDiagramCommandLabel,
Collections.EMPTY_LIST) {
protected CommandResult doExecuteWithResult(IProgressMonitor monitor, IAdaptable info) throws ExecutionException {
XXX model = createInitialModel();
YYY yyy = XXXFactory.eINSTANCE.createYYY();
yyy.setAttribute1("2");
yyy.setAttribute2("name");
model.getYYYs().add(yyy);
attachModelToResource(model, modelResource);
Diagram diagram = ViewService.createDiagram(model, XXXEditPart.MODEL_ID,XXXEditorPlugin.DIAGRAM_PREFERENCES_HINT);
if (diagram != null) {
diagramResource.getContents().add(diagram);
diagram.setName(diagramName);
diagram.setElement(model);
//diagram.createChild(yyy.eClass());
//diagram.insertChild(arg0);
try {
modelResource.save(.getSaveOptions());
diagramResource.save(getSaveOptions());
} catch (IOException e) {
return CommandResult.newOKCommandResult();

Expanded node and children are seen only after second expansion

Hi,
I am using a simple JTree control. I am populating children of nodes dynamically when the node is expanded. For this, I first add a "dummy" item for each node under the root, so that the "+" sign appears next to the node. When a node is expanded, I delete the "dummy" node and add children to it. However, the first time I expand the node, the node actually doesn't expand, though treeExpanded() gets called and all children are added correctly (I verified by debugging). When I expand the tree the second time, I can see the expanded node.
I am using TreeModel's removeNodeFromParent(childNode) and insertNodeInto(childNode, parentNode, childIndex) method to remove and add children respectively.I believe we don't have to explicitly call TreeModel's nodeChanged(), nodesWereInserted() etc?
Could you please let me know if I am missing something fundamental here?
Thanks in advance,
Praneeth

Hi db,
I didn't realize that there was a response to my earlier thread. I added the thread to my watchlist. I was under the impression that I would be notified via email in case of a reply to the thread. However, I didn't receive any. Anyway, I did reply to that response there now.

Reloading JTree and expanding last selected rows

I'm working on an applet that loads the nodes of a JTree from a database. When a node is selected, its data are displayed in a different panel. When a "reload" button is clicked, all the nodes in the JTree are removed except for the root node, and the JTree is recreated from the database. I'm try to get the new JTree to expand and select the rows that were selected before reloading, but I can't get this to work.
Before removing the nodes, I save the currently selected row numbers using JTree.getSelectionRows(). After recreating the JTree, I re-select the previously selected rows and try to expand them:
// tree is the name of the JTree.
tree.setSelectionRows(selected);
for (int i= 0; i < Array.getLength(selected); i++) {
            System.out.println("selected row: " + selected);
tree.scrollRowToVisible(selected[i]);
tree.updateUI();
The previously selected rows do not automatically become visible in the resulting JTree. I also tried using tree.expandRow instead of scrollRowToVisible, with the same results.
Any help would be appreciated!

I think part of your problem is this...
When you repopulate your tree, and only the root node is visible, getRowCount() will return 1. When you call expandRow(x) where x > 1, the result is basically a no-op (nothing happens). This is the correct behavior for these methods.
In other words, I think you need to come up with a whole new algorithm.
Let's assume you have a tree that looks like...
Node 0
|__________Node 0.0
|               |__________Node 0.0.0
|
|__________Node 0.1
|__________Node 0.2
                 |__________Node 0.2.0
                 |__________Node 0.2.1Try this...
//save the current open/closed state of the tree and selection state
Vector<Integer> selectedRows = new Vector<Integer>();
Vector<Boolean> openClosed = new Vector<Boolean>(tree.getRowCount());
openClosed.setSize(tree.getRowCount());
for( int i = 0; i < tree.getRowCount(); ++i )
   if( tree.isExpanded(i) )
        openClosed.set(i,true);
   else
        openClosed.set(i,false);
   if( tree.isRowSelected(i) )
       selectedRows.add(i);
//at this point we have all the needed state information
// rebuild to tree from the database now
// then do this
int rowIndex = 0;
while( rowIndex < tree.getRowCount() )
    if( openClosed.getElementAt(rowIndex).booleanValue() == true )
         tree.expandRow(rowIndex);
         // note that if a row gets expanded, getRowCount() will increase
    ++rowIndex;
// at this point, your tree should be expanded exactly as it was before the reload
int[] rows = new int[selectedRows.size()];
int index = 0;
for( Integer i: selectedRows )
   rows[index++] = i;
tree.setSelectionRows(rows);
// at this point the tree should have the same selection as before the reload.I hope this helps. Please reward me the Duke Dollars if it does. Not awarding the Duke Dollars kills the system (which is an honor system). A dead system hurts us all.
P.S. I guess I never referenced the little tree I drew. Oh well. It looks great doesn't it?

Move node and its silings from one jtree to another

Hi,
I am trying to move JTree nodes and its siblings from one JTree to another. If anyone has the code, please post it on the website or mail to [email protected]
Thanks
Pavan

Pavan,
You may have to do a sanity check before adding it.
Better run the program in a debugger and have a break point at the clipBoard.put() line. Else system.out.println() lines will kill enormouse programming time rather than using debugger.
Also in following this thread, i found that you may have to be bit more thorough with the DefaultMutableTreeNode class first.
Thanks,
ananth
Thomas,
for (int p = 0; p < jtree.getSelectionCount(); p++) {
               System.out.println(".3.......p= "+p);
node =
=
(EuamDefaultMutableTreeNode)paths[p].getLastPathCompon
nt();
                    clipBoard.put(node.toString(), node);
               System.out.println(".4...........");
Giving error at clipBoard.put()
line....java.lang.NullPointerException
..Any idea why?
Thanks.

Hi Expets,
My requirement is to create a new node and subnodes(zreports) in the Transaction SRET.
Where as i am able to create a subnode(zreports) under the existing node but not able to create a New Node and
Subnodes(zreports) under it.
To create the subnodes(zreports) i used Transaction SERP and i was able to create the new node in SERP but not able to find it in SRET.
So please help me out.

How to Create Instances in the Transient Root Node and Sub Nodes from Root Node Query Method ?

Hi All,
I am Creating a BOPF BO with 3 Nodes,
Node 1) ROOT -- > contains a query,
using Root Node I have created Search UIBB Configuration in FBI.
In testing -- > when i enter Data in the Search Criteria Fields am able to get the details in to the query method

I am Unable to set data to the Node . I did not get any error message or Dump while executing . when i tried to retrive data I got the details from the node but am unable to view those details in the FBI UI and BOBT UI while testing .
Please provide your valuable Suggestions.
Thanks in Adv.
Thanks ,
Kranthi Kumar M.

Hi Kranthi,
For your requirement you need only two nodes. Root Node and Result node. Use the same structure for both.
To create Instance while search.
Create Query method with input type which has the required fields for selection criteria.
Fetch the data and create instance in the root node.
Pass the new instance key as exporting parameter form Query Method.
To Move data from ROOT to Result.
Create a action at root node.
Write a code to create new entries in Result node.
Then configure the Search UIBB and display result in List UIBB. Add button and assign the action MOVE_MAT_2_RESULT.
Create another List uibb to display data from Result node.
Connect the UIBBs using wire schema. SEARCH -> LIST(ROOT) ---> LIST(RESULT).
Give src node association for ROOT to RESULT Configuration.

Sunil

How to create a new Node and bind it to the wdContext root at run time

Hi experts,
Does anyone have sample code about 1) adding a new node to the root context, 2) give it a name and 3) referring to this newly created node with the conetxt path?
Thanks

Armin,
I am trying to do this and keep getting erro about incompatible class:
wdContext.getNodeInfo().addChild("DynamicNode",
              mymodel.class,
              true,
              CMICardinality.ONE,
              CMICardinality.ZERO_TO_ONE,
              true,
              wdContext.getContext().getStructure("com.my.structure") );
              IWDNode node = wdContext.getChildNode("DynamicNode", 0);
              IWDNodeElement e = node.createElement(an_instance_of mymodelObject());
              node.addElement(e);
Can I do it this way?

Lining up root node and child nodes in JTree

I have a JTree that has a root node and n child nodes. There are no sub-levels - it is structured just like AOL instant messenger. What I want to do is have the child node icons line up directly under the root nodes text. For example (if you can read this), where "-" denotes the icon:
- root
- child
- child
Currently it is something like this:
- root
- child
- child
I have been messing with the setLeftChildIndent( int ) and setRightChildIndent( int ), but they are not doing much...they seem to not want to only move the leaf nodes but all of the nodes, so its not doing exactly what I want.
Any ideas? In the meantime I'll be looking more into how exactly those indent mutators work.
Thanks!

What you want is to do a setRootVisible(false) on the JTree.
All your child nodes are then your "root level" folders.
tree.setRootVisible(true):
+root
+--child1
+--child2
+--child3
+----child3a
+----child3btree.setRootVisible(false):
+child1
+child2
+child3
+--child3a
+--child3b
