Progress Event in class

Hi, I'm trying to get a grip on writing classes. I have a
simple preloader class which sort of works. When I trace
_percentLoaded from within the class the percentages are output
when I add the class to an fla. But, if I trace _percentLoaded from
the fla I get NaN. Is there a way to pass the progress event data
into the fla? Thanks

right, it's a little tricky. Offhand, you could choose from:
- place the event handler function on the main timeline (it
doesn't have to be in the same class)
- from within your class, create a dynamic handler function
on the timeline (which might be a pain)
- callback to the timeline with the data
- from within the present handler, broadcast a custom event
that gets handled in the main timeline
the communication might require instantiating like so:
new SimpleLoader(this)
from the main timeline so that your instance could then refer
back to the main timeline
which is the reverse of what you'd normally think of:
var loader:SimpleLoader = new SimpleLoader()
so that the loader can be accessed from the main timeline via
the var "loader".

Events in classes LabVIEW 8.6

i have class with some member (counter of something)
and i want to generate a user event when this member has specific values.
currently i manage to generate the event only if i register the event of the class
in the Top Vi that use this class
can i register the event inside the class itself, let say inside the initilize vi that i ave for the this class ?
thanks
Solved!
Go to Solution.

The question is a little confusing. You can register for the event anywhere you like, but somewhere you pretty much need to have an Event Structure in a running VI waiting for that event to occur.
What should be aware of these events? Class members
P.S. On second reading, it seems you might just be asking if you can register the event in a class VI, instead of having to register it in the top-level VI. If that's the case, then yes you can. Just have the Register for Events function inside the Initialize VI of your class and have it output the Event Registration Refnum corresponding to your event.

Creating a singleton Event Listener class

A typical singleton OO design pattern involved a protected (or private)
no-arg
constructor and a public instance() method that manages a private static
variable
referencing the single instance, internally invoking the no-arg constructor.
A class designated in web.xml as a <listener> must have a public no-arg
constructor.
(from http://e-docs.bea.com/wls/docs61/webapp/app_events.html#178593)
Anyone thoughts on how to accomplish both goals?
What I want to do: I'd like to set up a singleton to listen for session
events.
Other code will query this one-and-only-one session event listener for
various
information. Some of this info I can currently get from the runtime via
MBeans but
some I can't, hence my investigation into session event listeners.
TIA, matt.

Hi Matt,
This sounds like a case where you will need to have two classes -- your
singleton class, and then your session event listener class, which would use
the singleton class.

JTabbedPane single event handling class.

I have a list of proxyNames which are stored in a Vector.
These proxy names are then displayed as Tabs accordingly.
For every tab there is a specific action to be performed.
I want to write a single event handling class for handling all events.
What I have is this:
while(eNum.hasMoreElements()){
Object proxyName = eNum.nextElement();
tabbedPane.addTab(proxyName.toString(), null, null, "Proxy");
tabbedPane.addChangeListener(itemHandler);
panel4.add(tabbedPane2);
class ItemHandler implements ChangeListener{
public void stateChanged(ChangeEvent e){
for(int i=0; i < v.size(); i++){
// Perform action on choosing the concerned tab...
How do I have a single event listener?

Yikes! Is that a minimal program? When I am trying to do something new, or facing a problem that causes me to get stuck for more than an hour, I create a short program to solve just that problem. In time, you create a directory of test programs that's useful, and with practice, solving a problem in isolation is a faster (and generally better) way to go about things that doing it all in a larger application.
Any way, here is your code, with a change listener added in method makeSubpanel. If you don't want the listener called the very first time, add it at the end of this method. I also fixed some bugs in createProxyList.

How to use the PROGRESS Event?

Can someone explain to me how to use the PROGRESS event, i looked at the docs but it never helped me?
I want to use it to display the prgress of downloading data from a API, its a URL event. But i was told i can do this via a PROGREE Event

copy and paste the trace output from:
import flash.events.ProgressEvent;
//var facebookAPI:String = "https://graph.facebook.com/ginorea1/feed?access_token=277830088900615|2.AQDUBMBocIw_QcqE.3600.1313856000.0-100001000396080|5bXT8Cj0OUxNpr7y NeqTsJfwADg";//

var loader:URLLoader = new URLLoader(new URLRequest(facebookAPI));
loader.addEventListener(Event.COMPLETE, loadComplete);
loader.addEventListener(ProgresEvent.PROGRESS,loadProgress);
function loadProgress(e:ProgressEvent):void
trace(e.bytesLoaded,e.bytesTotal);
progress_txt.text = String(Math.floor((e.bytesLoaded/e.bytesTotal)*100));
function loadComplete(e:Event):void{
processData(e.target.data);
function processData(data:String):void

SwingWorker, setting progress from other classes

Hi.
I'm interested in SwingWorker. It's very good tool for long running task in GUI applications. I want to use progress feature, but I don't want to code the logic of my long running task into its doInBackground() method. I have some class (which creates some other classes) which reflects my problem in reality. I want to use this classes for other problems too. So I would like to update progress from this class. Ideal case would be if the method setProgress() in SwingWorker was public, so I can create optional constructor with additional parameter for SwingWorker class (and its subclasses) and call method setProgress from this class. Does anybody know about some solution? I'm still thinking over, but I cannot find ideal solution.
Thx for help

Your configuration remains incomprehensible.
From the other thread you mention a Listener which gets asynchronous messages. Are we talking about a context listener which handles JMS messages or the like? From these message you get a value and set it in a bean property.
Then we get lost. You say you want to pass this value to a Servlet, presumably by passing a reference to the bean. But how is a particular incoming message associated with a transaction going through the Servlet? How do you imagine the bean reference being passed. A ContextListener doesn't see the web transactions. Should these bean values affect all subsequent transactions? Is there some kind of key in the web transaction that makes it look for data from a particular JMS message?
In general the way for a ContextListener to pass data to a Servlet is by setting attributes in the ServletContext, but you really haven't made clear what you're trying to achieve.
Try explaining in a more general way what your project is trying to achieve. You're concentrating on details which almost certainly don't contain the problem.

Broadcast events between classes (objects)

Hello,
I'm can't figure out how to broadcast an event to another
class.
In actionscript 2 I created 2 classes. The first class called
the second class to load a file from an url. When the file was
loaded I used dispatchEvent({type: "fileLoaded", target: this,
filename: sFilename})
In the first I simply wrote addEventListener("fileLoaded",
handleFile)
But with AS3 this no longer works.
Can anyone tell me how to accomplish this? Because I can't
find a clear example and I don't know how to do this.

In the defintion of your custom event I miss the isEnabled
part (don't know if that has anything to do with the issue though).
Below a custom event that works for me
package Components {
import flash.events.Event;
public class ZoomEvent extends Event
public var isEnabled:Boolean;
public static const ZOOM:String = 'zoom';
public var vertical:Boolean = true;
public var minvalue:Number = 0;
public var maxvalue:Number = 0;
public var zoomfactor:Number = 0;
public function ZoomEvent(type:String,
isEnabled:Boolean=false) {
super(type);
this.isEnabled = isEnabled;
public override function clone():Event {
return new ZoomEvent(type, isEnabled);
Furthermore I have somewhere read in the documentation that
using custom event should go together with adding an embedded
statement like: [Event(name="update",
type="Components.UpdateEvent")] in the class where you use the
event, but for me it also works without this embedding code (???)
And is your class XMLData a subclass from a class that
supports dispatchEvent. I do not know what classes support
dispatchEvent, maybe all. Then this remark makes no sense.

Hi all
Can any one explain me the functionality about events and event handlers in ABAP OO??
Thanks and Regards,

Hi there
Whilst the SENDER doesn't know about the RECEIVER the reverse is not true. Some people might (wrongly) infer from the comment about the sender that the receiver doesn't know either. I'm only adding the comment below hopefully to clear this up for some people who perhaps a new to OO programming and OO ABAP in particular.
By using the parameter SENDER the receiver can know what object triggered the event. This is of course useful where you have say multiple grid displays on the screen and an action needs to be performed depending on what object triggered it.
class lcl_event_handler definition.
* CLASS     cl_event_receiver
* DEFINITION
public section.
    methods:
*--To add new functional buttons to the ALV toolbar
handle_toolbar for event toolbar of cl_gui_alv_grid
importing e_object e_interactive
          sender,
*--To implement user commands
handle_user_command
for event user_command of cl_gui_alv_grid
importing e_ucomm
          sender,
class lcl_event_handler implementation.
*--Handle Toolbar
method handle_toolbar.
*    PERFORM handle_toolbar USING e_object e_interactive .
endmethod .
*--Handle Hotspot Click
method handle_hotspot_click .
*    PERFORM handle_hotspot_click USING e_row_id e_column_id es_row_no .
create object go_handler.
    set handler go_handler->handle_user_command
    for go_grid1.
set handler go_handler->handle_user_command
    for go_grid2.
form handle_toolbar
case g_sender
when go_grid1
etc
sorry if this info is a case of "stating the obvious" but reading the forums there's quite a bit of confustion surronding event generation and handling in OO ABAP.

Could i use page unload event in Class Library (Web part)?

Hi,
I am creating Web Part using visual studio class library. I am going to deploy it in SharePoint environment.
I want to do some functionality while page unload. Is there anything like that?
Could anyone tell about it?
Thanks & Regards
Poomani Sankaran

Hi,
According to your description, my understanding is that you want to create a web part programmatically and then do some functionality in the page unload event.
There is a web part method called WebPart.OnUnload method, you can override this method and add the custom code to the override method.
Here are some detailed articles for your reference:

Configure event of class to trigger workflow...

Hi,
When a material is created, the standard event CREATED gets triggered of BO 'BUS1001006'.
But my client wants everything to be handled based on classes.
So i have created a custom class and its custom event 'CREATED' which needs to be triggered once a material is created.
So my question is how will i trigger this custom event of custom class. Is there any configuration that needs to be done for the same?
For now, i am planning to trigger the custom event in a BADI or user exit using standard FM 'SAP_WAPI_CREATE_EVENT'.
Kindly suggest your ideas.
Regards,
Guddan

Hi- My suggestion is, let the WF be triggered using std BO and event. For additional custom methods, you create a new WF based class
Also you need to decide, is it required to create an instance for the class (for instance method)

Events in Class Constructors

Hi All,
I would like to know if events (instance/static) can be raised within class constructors. My understanding is that events can be raised but not of the same class as the class constructor belongs to.

About events of class cl_gui_alv_grid

When the following two event gets trigger in execution.
I mean by clicking what they get trigger or how we can triger them and how to use them.
menu_button
data_changed
In general how one can understand that which event will be triigered when from the class event.

Hello Amit
In order to understand the event DATA_CHANGED in more detail you may have a look at Get edited data ou of grid back into internal tabel
and the links provided therein (in particular my discussion with David Halitsky).

Controlling events between classes

hello
i know i'm asking a lot, but i couldn't find anything. the problem is i've got a jframe and some panels with buttons.
eg:
class A extends JFrame
getContentPane().add( B ) ;
getContentPane().add( C ) ;
class B extends JPanel
add( button1 ) ;
add( button2 ) ;
class C extends JPanel
add( button3 ) ;
add( button4 ) ;
where do i add ActionListeners? how do i pass information between classes? if button1 is clicked -> class A should know it.
i tried to do this in class A: objectOfB.button1 (access button1 directly) - didn't work - why?
if a button1 is clicked i want to remove the jpanel and replace it with another one. how should i do this?
Thank You All

Check out the java tutorials. There are great examples that show you how to do what you want to do

Interlaced render/export of Progressive event

Footage shot in SD 30fps Progressive loaded into timeline.
If rendered Progressive and exported, edges look jagged, lines striated.
If rendered Interlaced and exported, looks good (both on computer screen via Quicktime, and on LED via BrightSign).
What sense might this make, considering it was shot Progressive?
Thanks.

FAQ: What information should I provide when asking a question on this forum?

Remoting, LiveCycle & Progress Events

So, one of the examples that Adobe provides is titled "Generating a PDF file from a Word file using LiveCycle Remoting". I am using variants of this and it works pretty well.
When you upload a file to LC, you can of course set up some event handlers for the ProgressEvents so you can show status of the file upload.
In a similar way, my question is, what happens when a person wants to convert a 450 page Word document. That could take a while. How do I inform the user of the status other than "Complete"?
Is it possible to provide a % complete? Am I limited simply having a status field with 2 states, "Running" and "Complete"?
