How to generate selection change event through code in JTree?

I am developing an application which downloads the file from other system and adds it into the tree. On selecting any file in the tree I m displaying it's contents. But now i am trying to display the contents of downloaded file as soon as it's download completes. Here i am not getting the way to how to generate the event as the download completes, because i tried that setSelectionPath(TreePath path), but it also don't generates the selection change event. Is there any other way to do so?

Put null in place of oldLeadSelectionPath. From the API for TreeSelectionEvent:
protected TreePath oldLeadSelectionPath:
leadSelectionPath before the paths changed, may be null.
I'm at the office and can't try out anything, so please let me know whether that works for you.

Gridview SelectedItems property. How can i change the images of respected selected items?
Please reply me asap.
Thanks in advance.

Hi, Sorry for late reply,
Please change the class :
public class ImageCollection : INotifyPropertyChanged
private string source;
public string Source
get { return source; }
set { SetProperty(ref source, value); }
public int MyProperty { get; set; }
protected void SetProperty<T>(ref T storage, T value, [System.Runtime.CompilerServices.CallerMemberName] String propertyName = null)
if (!object.Equals(storage, value))
storage = value;
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

How to Generate a ReportError Event

I'm sure I'm just missing something here. Our LabVIEW GUI has a registered event Callback for ReportError. In TestStand I handle errors with SequenceFilePostStepRuntimeError and ProcessModelPostStepRuntimeError callbacks. I used the error handling example and modified to basically just show a popup with the error message. My problem is how to generate the ReportError event so our GUI can take the appropriate action.
I don't see it listed under the given UIMessage event codes. I can't find it anywhere. So the questions is where do I generate the ReportError event within TestStand?
Thanks.

Hi Sir Mutt,
If my understanding is correct, you are using LabVIEW as your operator interface to start the Teststand Application and you want to do Teststand Error Handling in LabVIEW. The most common way that this is achieved is through ActiveX Invoke and Property nodes as well as ReportError events. I have attached two screenshot examples of this. Does this sufficiently address your question or did I misinterpret your question?

How to handle tab change event in UI shell main area

Hi,
I have two tabs(two taskflows) in UI shell main area. one is department tab and another is employee tab. My department tab shows employees department wise. On employee tab I have emplyee table which shows employees jobwise. This employee table has the functionality of adding new record to employee vo as well.
Now i follow these steps.
1. by defualt department tab is open.
2. by clickinng on Tasks menu link i open Employee tab in to main area. Now i have both tabs in main area.
3. at Employee tab I search all employees job = accountant. It shows the search result well.
4. Now i add a new record to it and without saving/deleting this record i move to department tab.
5. at Department tab i search employees where department =20, here no relation b/w job and department.
6. Now i return to employee tab. my newly added record got disappeared. It is there but does not show in table.
How to resolve it??
I have one solution in my mind while changing the tab i can prompt to user "you can not leave the newly added record..either save it or delete it". But how to catch tab change event here? where i can write code to prompt msg to user?
Pls help.

With apologies for the slow reply, I'm currently travelling.
Two things to note:
1) The af:document uncommittedDataWarning flag was designed to stop users navigating away from half entered records. More about this flag can be found here:
http://docs.oracle.com/cd/E23943_01/web.1111/b31973/af_orgpage.htm#CACDDDFH (see point 4)
http://www.oracle.com/technetwork/developer-tools/adf/unsaveddatawarning-096556.html
....please note our documentation from time to time spells this flag wrong with only one "t" in the word committed, so if you're attempting a bulk search check for this (and I'll raise document bugs to get this fixed in the future).
2) On addressing the ADF UI Shell, if you're switching between "pages" in the UI Shell, as separate to switching between dynamic tabs within a single page using the UI Shell, the UI Shell will actually restart the currently running task flow in the page you're returning too. You can verify this by implementing an initializer on your task flow with a log message, and watching when the initializer is called.
In addressing your last question, at this stage I think you need to assess my first answer then come back if you think you sill need to execute the code on the tab click. I also need to know are you talking about the primary level of tabs that represent each page in the UI Shell, or are you referring to the dynamic tabs within a single UI Shell page that hold your task flows?

JSpinner generates multiple change events

Having problem with JSpinner generating two change events when using double values in the model. It looks like the number editor formatter is causing an event to be generated before it rounds and after it rounds.
          final JSpinner s = new JSpinner(
               new SpinnerNumberModel(20.0, 0.0, 100.0, 0.0025));
          s.setEditor(new JSpinner.NumberEditor(s, "###0.000"));
          // When value is changed, need to process certain events.
          s.addChangeListener(new ChangeListener() {
               public void stateChanged(ChangeEvent event) {
                    System.out.println("New Value:" + s.getValue());
          JFrame f = new JFrame("Test Spinner");
          f.getContentPane().setLayout(new java.awt.BorderLayout());
          f.getContentPane().add(s, java.awt.BorderLayout.CENTER);
          f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          f.setSize(331, 254);
          f.setVisible(true);If you modify the editor to use the following format, you can see that the two events are not generated because the formatter does not need to round:
"###0.000##############"I have to actually modify the model to round the incremented or decremented value to a precision where the formatter will not round the value, which is a pretty messy solution.
Are there any other workarounds (or solutions) that are a little more elegant?
Thanks.

Thanks for the reply.
This workaround reduces the amount of duplicate events, but I still see double change events that make it through the filter.
You have to filter events to get the relevant one.

CFDebug says, "widget: Firing selection change event for tree id: t1"

How do I capture this event and code against it. Previously used this code to trap click event:
YAHOO.example.onTreeViewAvailble = function() {
var curTree=ColdFusion.Tree.getTreeObject('t1');
curTree.subscribe("labelClick", function(node) {
TreeItemClick(1,node.data.id)
When the tree becomes available (ie. after the page loads),
this code will run the code above this.
"t1"- tree name in the cftree tag
YAHOO.util.Event.onAvailable("t1", YAHOO.example.onTreeViewAvailble);
I am obviously not an expert with the Yahoo widgets, but I'm learning.
This stopped working for some reason. However the CFDebug consistently shows the subject event happening on every mouse click. I'd rather just use that. Any ideas?

Roy, have you tried to reduce the complexity of your user case?
Try your use case with a simple page without a region in it first and see if you get the eating them. If yes add a region to your page and verify you get the result you expect. Only then add the portal stuff.
This will help to narrow down the error.

How to handle Iviews and UWL through Code?

Hi All,
I want to know
1)Is it possible to assign a iview to a user as a UWL task.
2)If yes how to do it through code?
Please reply soon!
Points will surely be given to helpful answers.
Sumit

Hi Sumit,
Can you elaborate on this ? Do you mean that a user should be given access to an iview only through UWL ? Or is it that if he clicks on a UWL item, he sees the iview there ?
You can surely open an iview on the click of an item in UWL. The configuration has to be made in SWF_VISU by selecting type as portal application, giving the pcd location of the iview (portal object).

How do I select current Event in Applescript?

I'm trying to create an Applescript that will act on the actively selected Event in iCal. The equivalent functionality in Mail is accomplished by setting your variable to "selection".
However, in iCal, selection is not a property, and I can't find anything similar. The only way appears to be to get all events in a calendar, then prompt to choose which one you want.
Any help would be appreciated.
MacBook Pro Mac OS X (10.4.8) iCal 2.0.4

John, thanks for your answer. However, I was hoping for a programmatic way, just by having the Event selected, instead of having to type in begin and end dates each time I want to select an Event.
Actually, I think I did figure out a way to do it last night, through a round-about way. I found someone else's script that copies the selected Event to the clipboard, then pulls out the first 2 lines of text, which are the Summary and Date. I then have my script repeat through all Events looking for the Event that has the same Summary. Once it finds it, I then have the reference to my selected Event.
I patched it together with another script I found, so I can now manually change the Attendee status for Events, since iCal won't automatically process replies from MS Outlook users. If anyone's interested in my finished applescript, let me know, and I can post it here.

How to trap Selection change

Hi All,
I need to observer selection change. How do i go about it. In basicpersistinterface the kBPISelectionObserverImpl is bound with the panel. Similarly I want to call a method on selection change and not update some UI, so where do i need to put my ActiveSelectionObserver.
It can be just displaying an alert of selection change, but how do we trap it.
Please contribute your valuable suggestions.
Thanks in advance.
Jasmine Shaikh

You can aggregate your observer to any easily accessed boss that's permanently around. For example kSessionBoss already has 15 observers, kAppBoss has 7 observers. You would use a private IID, though. Invoke AutoAttach from a StartupShutdown service.
Given that, you're probably wrong architecture-wise by watching the selection without UI involved. There are plenty other notifications, besides there are also different mechanisms to watch the selection from closer on (e.g. SelectionExt). Can you give more details on your intent?

Spark Datagrid Selection change Event

starting to work with the spark datagrid.
I want to send off a web service using the values of a row right after they get done editing the row and leave it.
No more change event that I can see like MX and gridItemEditorSessionSaveHandler kicks on every tab between cells
if I use event.currentTarget.selectedItem
Selection Change gives me the new row.
Selection Changing only kicks with mouse row changes not tabs
Suggestions?
I want to register the row with both mouse (on a numeric stepper) and tab(for text fields) events.
Thanks
Dan Pride

Hi Dan,
Try valueCommit event handler, but I'm not 100% sure that is triggered upon dataProvider data changes.
Another way is to listen for changes in the dataProvider variable.

How do I select multiple events in iCal 8.0?

In OSX Mavericks, I used to be able to select multiple events in iCal in the event list view. I could select the initial event in the span of events to be selected. Then hold Shift while selecting the final even in the span of events. As a result, all of the events in that span would be selected.
in OSX Yosemite, this is no longer possible. There appears to be no list view, and holding the Shift button does not allow me to select a span of events.
What is the best way to select a span of events, say as much as 30 events?
Thank you.
