How to generate event from a JTree node

I plan to move a vector list to a JTree and then make it possible to launch an even by double clicking a node in the tree, how can i quicly achieve that cuz i have being trying to overcome that since...any assistance?
Thanks

Since TreeNodes are no Components you have to add a MouseListener to your JTree and use the JTree.getPathForLocation(int x, int y) method to get the TreePath. something like this should work for you:
tree.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount != 2) return
JTree tree = (JTree)e.getSource();
TreePath path = tree.getPathForLocation(e.getX(), e.getY());
TreeNode node = (TreeNode)path.getLastPathComponent();
Do whatever you want here
Hope that helps, Mathias

How to move focus from one JTree node to another one and then back again?

Hi all!
Say I have a very simple JTree
package main;
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextField;
import javax.swing.JTree;
import javax.swing.event.TreeSelectionEvent;
import javax.swing.event.TreeSelectionListener;
import javax.swing.tree.DefaultMutableTreeNode;
public class SelectableTree extends JFrame implements TreeSelectionListener {
    public static void main(String[] args) {
        new SelectableTree();
    private JTree tree;
    private JTextField currentSelectionField;
    public SelectableTree() {
        super("JTree Selections");
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent event) {
                System.exit(0);
        Container content = getContentPane();
        DefaultMutableTreeNode root = new DefaultMutableTreeNode("Root");
        DefaultMutableTreeNode child;
        DefaultMutableTreeNode grandChild;
        for (int childIndex = 1; childIndex < 4; childIndex++) {
            child = new DefaultMutableTreeNode("Child " + childIndex);
            root.add(child);
            for (int grandChildIndex = 1; grandChildIndex < 4; grandChildIndex++) {
                grandChild = new DefaultMutableTreeNode("Grandchild "
                        + childIndex + "." + grandChildIndex);
                child.add(grandChild);
        tree = new JTree(root);
        tree.addTreeSelectionListener(this);
        content.add(new JScrollPane(tree), BorderLayout.CENTER);
        currentSelectionField = new JTextField("Current Selection: NONE");
        content.add(currentSelectionField, BorderLayout.SOUTH);
        setSize(250, 275);
        setVisible(true);
    public void valueChanged(TreeSelectionEvent event) {
        currentSelectionField.setText("Current Selection: "
                + tree.getLastSelectedPathComponent().toString());
}All I need is to move focus from currently selected node, to some other node (does not matter which one), then to "sleep" for a second and finally move it back to return selection to the previously selected node. The only question is how do I do this?

Use a Seperate Thread to do it:
Runnable r = new Runnable() {
    public void run() {
               int k=tree.getSelectionRows()[0];
               DefaultMutableTreeNode node = (DefaultMutableTreeNode)tree.getLastSelectedPathComponent();
                            if(node.getNextSibling()!=null)
                                 tree.setSelectionRow(k+1);
                            else
                                 tree.setSelectionRow(k-1);
                            sleepe(k);
public void sleepe(int i){
                     try{
                            Thread.sleep(1000);
                                 }catch(Exception e){
                                     e.printStackTrace();
                              tree.setSelectionRow(i);
    }Then start this thread in a mouse click event(or any other similar),but not in TableSelectionListener because >>if the current selected row is 1 then it will execute the valueChanged method of TableSe..li. and we set the selected row to 2 then again it will execute the valueChanged method of TableSe..li.It will repeat till something,or in error.
tree.addMouseListener( new MouseListener(){
public void mouseClicked(MouseEvent e) {
                   new Thread(r).start();
public void mouseEntered(MouseEvent e) {
public void mouseExited(MouseEvent e) {
public void mousePressed(MouseEvent e)     {
public void mouseReleased(MouseEvent e) {
});Note:it worked perfectly for me. So add all the above in the right place and import necessary.It will execute perfectly.

How I Generate Event from ADF to talk BPEL

Hi ,
I want to generate Event in ADF on click of button.
That Event suppose to send message to BPEL process.
Can anyone suggest me on this?
Thanks,
Ramit

You would need to use Mediator component in the SOA composite to listen to this event generated from the ADF layer.
The Mediator can route to the BPEL component where you could do the required processing.
ADF Developer's guide has all the required information with respect to this:

How to search data from a context node.

Hi Friends,
Thanks for ur help for previous problem . I am facing some other problem i.e how to
search data from a context node.
i have a context node :-
Car(main node) which consist of details, owners, engine and Brand as its sub node.
the value attibutes of difft nodes are:-
Car- category
Details- Mileage, Price, registration_no, miles_used
owner - name, phnno,addrs
Brand - main_brand, co_brand
Engine- Bhp,Rpm
Now i have to apply a search criteria on the basis of price, miles_used .
pls help to implement that .
Thanks & regards
Pravin jha

Hi PRAVIN,
What I can understand from your problem is that, you have a list with various properties and you want to display them and search them in your WD App. If I am correct, use the following approach:
Instead of using "details, owners, engine and Brand" Nodes, use the attributes inside the parent node. i.e in the node Car, add all the attributes viz. Mileage, Price, registration_no, miles_used, name, phnno,addr etc.
Now you can create a table of this node "Car" and can easily search on the basis of any criteria.
I hope this solves your issue. If you are looking for something else, please revert, I'll be happy to help you.
Cheers!!!

How to get event from message?

Hi,All:
I write a run-time interface by CVI, I use TS_EngineRegisterUIMessageCallback to register my callback function, but when message passed to the callback function, as the type is struct IDispatch but not CAObjHandle, I don't know how to read event from message.
Can you help me to solve it? Thanks
Chang Zhang

Hello Chang-
If your question is simply how to obtain an object handle from an object of type IDispatch, have you investigated the function "CA_CreateObjHandleFromIDispatch"? I would recommend you look over the testexec.prj that is installed along with the TestStand engine (the CVI Operator Interface) and inspect how we handle our callbacks, this may help you understand how to go about emulating the behavior in your own project. To see this particular function in use it may be most helpful to look in the file 'engine.c' and inside the function UIMessageDeferredCallback here you will see the IDispatch pointer being handled and decoded for use by the TS engine.

Generating events from a control inside an array of clusters

Hi, I have a question regarding UI events. I would like to capture a mouse down event generated in a string control inside of an array. Each element of the array is a cluster that has a Boolean control, a numeric control and a string control. When I try to add an event to handle the mouse down the only option available in the event structure is the one available for the entire array. If this is not possible to map event from the individual controls inside of the each cluster that are part of the array, could you provide with an alternate way of "knowing" when the string control is selected. The application has a touch screen without a keyboard and mouse. I need to display the touch screen graphic keyboard when the textbox is selected.
Thanks,
Diego F.

I'm not sure, but I think your only option may be to do some calculations. The mouse down on the array will give the coordinates of the click in VI coords. You can get the coords and size of the cluster and the coords and size of the string using their property nodes. Then, you have to calculate whether the click was on one of the visible strings using addition, subtraction and quotients. Once you make a subVI out of this, it should be easy to use.
You should watch out for the index display and the label, as they change the values of the coords. I'm sorry, I can't think of any easier way to do this.
Correction - I just thought of one. If you use the KeyFocus property on the string inside the mouse down event, it seems to work. I'm not sure whether this will work when bringing the keyboard to the front, which is why I left the other suggestion in place. Here's my test (7.0)
Try to take over the world!

Hi
Thanks for your help but I really didn;t found what I'm lookin for in this page.
This page explains how xslt transform xml in xhtml. I know this point, I want to know HOW could I make it from my application. I guess there are a transform class that could generate html from a xsl template, but I couldn't find the way to do it and couldn't find examples too.

How to pass events from subpanel(s) to the main VI ?

hi all,
I found a lot of solutions to pass the events from the main VI to the subpanel(s) but none about passing the events from subpanel(s) to the main VI. In the attached VIs, I just want to generate an event in the main_VI.vi when I click on the button positionned in the subPanel1.vi. How can I do that ?
thanks.
Cedric

Cedric,
You could use a queue to transfer the button data to your main vi.
See the attached files:
subPanel1mod - Detects a button change and Enqueues the state.
main_VI mod - uses the Timeout event to poll for data in the queue.
main_VI mod1 - gets the queue data without having to poll.
Like your orginals, these files are in LV2010.

How to generate XML from EBusiness suite ARXSGPO

Could someone tell me how I can generate XML from the EBusiness Suite Accounts Receivable report ARXSGPO.rdf I understand this report is called by a C program. I have tried changing the concurrent request to output format to XML the result does not resemble XML. Does anyone have any suggestions how I can generate XML from the ARXSGPO report?
Thanks,
Mark

Hi Mark
the next release of XMLP will have last page only support. The problem is that at the template layer you do not know how many lines are going to fit on the page, so you never know what is going to be the last page. The only way around it for now is to specify the number of lines to a page and then check when all the lines have been rendered and then render the remit portion.
I have a sample invoice that does the same, drop me a mail, you can work out the email from my name and the fact I work for XMLP Im sure.

How to generate report from two tables using DAO design pattern?

Hi,
Iam using struts with DAO pattern for my application. According to DAO design im creating model class for each table in my database with getter,setter methods. i have no problem when im generating report from one table. but if have i have to join two tables whatis the better way for doing that? is it good practise to create a new model contains properties from both the tables?
Please help me
Thanks in Advance
Rajesh

Dear Rajesh,
As per the pattern you are creating equivalent java objects for every database table under consideration in which each db field will become a private attribute and public getter and setter methods.
If you have to display data from one table the above approach is sufficient enough.
But in case your database is normalised ..lets take an example of Bank having Branch and Accounts tables. We dont need to repeat the whole information of the branch for every account in that branch. so we prefer to have a branch id in that table....this approach lot of insertion/deletion/updatation anomlies that may exists with the database...
now lets come back to our topic....we shall create two java objects 1) Branch 2) Account.....
When ever u just need to display simple report u can do it staright forward,,,,,now if u want to display branch information along with the account information....the two objects just created are not sufficient
So i suggest u the following approaches
1) Create an attribute of type Branch in the Accounts Object......
This shall serve the purpose of displaying the Btranch information
2) Create a collection object of type ( Vector or ArrayList) which can have objects of Account in the Branch Object,,,
Now its upto u how shall u fill up the objects with appropriate sql queries.
The method that i mentioned is followed by Oracle Toplink and Hibernate ....which provide Object to relation mapping layers.
Any queries ...revert back to me...

How to generate PDF from an IView

Hi all,
I have been reading a lot about generating PDF document, smart form, adobe LiveCycle Forms, BAPI's..etc. but I can not find anything more simple:
I just would like to show (and maybe save and print) in PDF format (maybe in a popup) an IView content.
I have read how to generate a pdf file from a binary attribute of the Context, but nothing about how to fill this binary attribute with the data of the current showed IView.
Is this possible?
Thanks in advance,

Hello, Lohitha.
Thanks for your post. You are right, the general way to create a PDF is like that, using Adobe Interactive Forms.
Using this, I must design a form and fill it with data binding. But, in fact, what I'm requested to do is just convert the current IView into a pdf file without using any forms, but keeping the IView design.
Let me explain myself, It could be something similar to convert a .doc file into .pdf.
I tried this code;
     IPrivatePDFComponentView.IContextElement contextElement = wdContext.currentContextElement();
     byte[] bytes = contextElement.getPdfSource(); //here I get bytes = null since PdfSource is empty if I do not use Interactive Forms!!
     try {
          File file = new File("C:\temp\example.pdf");
          FileOutputStream os = new FileOutputStream(file);
          os.write(bytes);
          os.close();
     } catch (IOException e) {
          // do something
          e.printStackTrace();
Do you know how could I do that?
Thanks
