Custom events for custom classes

So what I'm trying to build is a custom class wich connects
to a php socket server using an XML socket.
I don't know how I can broadcast an event so I can write
something like the code below. Anyone can help ?

To be more specific my class looks something like this

Hello Uwe,
Each of them- "Dynpro" and "Programs" has 2 entries:
Dynpro     0100 Müller
               0200 Harryhirsch
Programs SAPTROX1

if you want to call any static attribute or method just do
CL_DOPR_WRITER=>method or parameter
but if you want to access pubic method or att

Hi
"At the beginning, i am using the Receiver Function module is SWW_WI_CREATE_VIA_EVENT.
after i change to "SAP_WAPI_CREATE_EVENT" but got error too."
Can you tell us where are you calling this FM (is it via Enhancement option or badi or exit) to trigger the event?
Just leave the Receiver FM as same as in SWE2 and make sure Linkage Actiavted check box is checked
"i can't do the buiding between &EVT_OBJECT& and &WI_OBJECT_ID&. because it is not same business object.
for our workflow object, it references to class is developed by me.
As suggested by Rick, you could make use of FM or as per blog, you could use class to trigger your custom class's event. Then you need to have binding at task level (PFTC)
&EVT_OBJECT& --> &WI_OBJECT_ID&.

Need help with custom event from Main class to an unrelated class.

Hey guys,
I'm new to Flash and not great with OOP. I've made it pretty far with google and lurking, but I've been pulling my hair out on this problem for a day and everything I try throws an error or simply doesn't hit the listener.
I'm trying to get my Main class to send a custom event to an unrelated class called BigIcon. The rest of the code works fine, it's just the addEventListener and dispatchEvent that isn't working.
I've put in the relevant code in below. Let me know if anything else is needed to troubleshoot. Thank you!

Alright, this compiles, gives me no errors, shows my 'book' and 'flowers' icons perfectly when ran, and prints 'addEventListener' to the output window as expected. I get no errors when I press the button, 'dispatchEvent' is output (good), but the 'twitchUp' function is never called and 'EventTriggered' is never output.

Creating event dispatching in custom class

I have been trying to create an event dispatcher in a custom
data transfer object class. It's a simple class and I don't know
how to make it dispatch an event. I tried extending the
EventDispatcher class but that doesn't appear to work either. Any
help would be greatly appreciated.

I have attached the code for the application and the custom
class. This should work from what I have read, but I can not get
the application to catch the event.
APPLICATION
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
creationComplete="initThis()" layout="absolute">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
private var _tester:TestClass = new TestClass();
private function initThis():void{
addEventListener(TestClass.TEST_ACTION, onTestHandler);
private function onTestHandler(event:Event):void{
Alert.show("Event Dispatched");
]]>
</mx:Script>
<mx:Button x="312" y="150" label="Button"
click="{_tester.testEvents()}"/>
</mx:Application>
CLASS
package
import flash.events.EventDispatcher;

public function testEvents():void{
dispatchEvent(new Event(TestClass.TEST_ACTION));

Listening to event within custom class

I've created a custom class that posts to a web page to authorize a user. How can I listen for an event within the custom class?
This is my code within my main class.
var customClass:CustomClass = new CustomClass();
var testingString = customClass.authorize("[email protected]", "password");
the fuction "authorize" within the customClass looks like this:
public function authorize(user:String, password:String):void
jSession = new URLVariables();
                              j_Loader = new URLLoader();
                              jSession.j_username = user;
                              jSession.j_password = password;
                              jSend.method = URLRequestMethod.POST;
                              jSend.data = jSession
                              j_Loader.load(jSend)
How can I fire an event within my main class once the j_Loader triggers Event.COMPLETE?

You can fire an event using the dispatchEvent() function.
In your main class you assign a listener for the event the CustomClass dispatches after it exists.

How to register mouselistener for custom class?

i m trying to create a custom class (extending java.awt.Rectangle)which responds to mouse gestures.
i m using it as an object on my drawpad which responds to mouse behavior
like rollover.
the rollover color change is achieved using canvas' graphics object triggerd by my cutom class
i m not able to register a mouseevent for the custom class.
can someone help me in achieving this?
thanks in advance
z_idane

Something like this? Don't think I'd be likely to extend Rectangle, myself, but anyway...
public class HotSpot extends Rectangle implements MouseMotionListener
    private boolean hover = false;
    // add constructors to taste
    public void mouseMoved(MouseEvent e)
        if (this.hover != (contains(e.getX(), e.getY())
            this.hover = ! this.hover;
            if (this.hover)
                // "mouse enter" code here
            else
                // "mouse exit" code here
    public void mouseDragged(MouseEvent e)
}Obviously you'd need something like this elsewhere,
myDrawingPad.addMouseMotionListener(new HotSpot(...));

Adding info blocks in a custom class for Factsheet

Hi Experts,
I need to create a custom class by copying the standard class 'CL_CRM_CCKPT_PROCESS_OPEN' which should accept input as Activity Types. At present this class only accepts Number of months as Input. This added input field should accept individual multiple values & Ranges and F4 help also needs to be attached for the field.
I would like to know how to add this new input field to the class 'CL_CRM_CCKPT_PROCESS_OPEN' .
Any valuable help would be appreciated & points would be rewarded generously for the same.
Regards,
Sangeeta.

Hi,
You can copy and include your fields in the class using transaction SE24.
According to your subject line you are trying to modify an existing factsheet display you own data. I would suggest instead of creating a modifying an existing class, implement your own function module and call this function module directly from the smartform used to for factsheet. This is an easier way to implement modification of factsheets instead of using the classes and displaying the data.
Reward with points if this helps.

Putting Loader in a custom class: events, returning to main ... asynch challenges

I'm creating a custom class to retrieve some data using URLoader.
My code is below, doing this from memory, plz ignore any minor typos.
The challenge I'm encountering: when my custom class calls the loader, the event handler takes over. At which point the context of my code leaves the function and it's not clear to me how I then return the data retrieved by the loader. I sense that I'm breaking the rules of how ActionScript really runs by putting a loader in a separate class; at least, that's my primitive understanding based upon the reading I've done on this.
So can I do this? I am trying to create a clean separation of concerns in my program so that my main program doesn't get clogged up with code concerned with retrieving remote data.
Thanks!
Main program;
import bethesda.myLoader;
var ldr:myLoader = new myLoader;
var data:String = myLoader.getData("someurl");
My custom class:
package bethesda {
     public class myLoader {
          function myLoader(url:String):String {
               var loader:URLLoader = new URLLoader();
               var request:URLRequest = new URLRequest(url);
               loader.addEventListener(Event.COMPLETE, completeHandler);
     function completeHandler(event:Event):void {
          var ld:URLLoader = new URLLoader(event.target);
          data = loader.load(); // here's where I don't know what to do to get the data back to my main program

I think you are on the right track in abstracting loading from other code.
Your class may be like that:
package
     import flash.events.Event;
     import flash.events.EventDispatcher;
     import flash.net.URLLoader;
     import flash.net.URLRequest;
     public class myLoader extends EventDispatcher
          // declare varaibles in the header
          private var loader:URLLoader;
          private var url:String;
          public function myLoader(url:String)
              this.url = url;
          public function load():void {
              var loader:URLLoader = new URLLoader();
              var request:URLRequest = new URLRequest(url);
              loader.addEventListener(Event.COMPLETE, completeHandler);
              loader.load(request);
          private function completeHandler(e:Event):void
              dispatchEvent(new Event(Event.COMPLETE));
          public function get data():*{
              return loader.data;
Although, perhaps the best thing to do would be to make this class extend URLLoader. With the example above you can use the class as following:
import bethesda.myLoader;
import flash.events.Event;
var ldr:myLoader = new myLoader("someurl");
ldr.addEventListener(Event.COMPLETE, onLoadComplete);
ldr.load();
function onLoadComplete(e:Event):void {
     var data:String = ldr.data;

Terminating Event for BUS2017 Custom Method

Dear Experts,
I have an issue with the Terminating Event of the Workflow for BO : BUS2017. The event is getting triggered but receiver is not being picked.
I have created two events GR_103 and POST_105 in the Custom BO ZBUS2017 by delegating it to BUS2017. GR_103 is the triggering event for my workflow which I have triggered in the POST_DOCUMENT Method of the Implmentation for BADI : MB_MIGO_BADI.
GR_103 is triggered while doing MIGO (Goods Receipt) for Movement Type 103. My Workflow is triggered perfectly and then I have used a Dialog Asynchronous Task in which I have called the MIGO Transaction for Releasing the GR Blokced Stock using the Movement Type 105. I have created a Custom Method POST in the BO ZBUS2017 and I have used the FM: MIGO_DIALOG to call the MIGO. I am trying to raise the POST_105 event in the Method MB_DOCUMENT_BEFORE_UPDATE of the Interface IF_EX_MB_DOCUMENT_BADI. I have defined the Terminating Event for the asynchronous Task as POST_105.
Now the event POST_105 is triggered, but SWEL says 'No receiver entered'. Even the SWEINST shows the object data as the current Work Item along with Object Key, but still receiver not picked. When I try to trigger the same event in a test report by using call transaction, then the event triggers and work item gets completed without any issues.
Please advise.
Below is my terminating event code.
READ TABLE xmseg INTO wa_mseg INDEX 1.
CONCATENATE wa_mseg-mblnr wa_mseg-mjahr INTO l_objkey.
IF wa_mseg-bwart = '105' .
    CALL FUNCTION 'SWE_EVENT_CREATE'
      EXPORTING
        objtype           = 'BUS2017'
        objkey            = l_objkey
        event             = 'POST_105'
      EXCEPTIONS
        objtype_not_found = 1
        OTHERS            = 2.
ENDIF.
Regards,
Raju.

Have a COMMIT WORK after the function call. (At least test it - I am not sure if it will have some effects in your BADI - at least you will know whether the issue is about missing commit).
And please use SAP_WAPI_CREATE_EVENT instead of the old function you are using.
Also, make sure that the events will look exactly the same in event monitor SWEL when triggered from your code and when using test tool. Maybe there is some minor difference/mistake (object key, etc.) that you haven't noticed.

Karri

Unicode issue for custom CLASS

Hi Experts,
we have a custom CLASS 'Z_ADD_INN_SALES' as part of unicode conversion i have corrected all the unicode compliants found in the UCCHECK transaction associated with the CLASS and also marked unicode check in the properties of the class. But still it is saying it is not compatible for unicode. I am not able to activate the object because of this error. Kindly let me know whether i need to do any thing else which i have missed for unicode check.
Regards,
Ram

Hello Ram
Apparently there is a coding-related Unicode error in the class. Check it with UCCHECK and analyze the error message.
For more details refer to:

Creating custom class instances for XML nodes

Hi guys,
I'm trying to load an external XML document in my application
and create an instance of a custom class for each node in the XML
based on the value of some of their elements. The instances created
will eventually end up in a DataGrid by the way. The problem I'm
having is there seems to be many ways of doing small parts of this
and I have no idea how to make them all gel. Initially I'm using
HTTPService to load the XML file but I've seen people just use an
XML object. Then, after that, I initially set the loaded XML to an
ArrayCollection but others have used XMLList or XMLListCollection.
I've no idea what's the best way to do this.
Eventually, when I've created all of these instances by
looping over the XML and creating them how will I make them
bindable to the data grid? I'm guessing I'll have to group them
somehow...
Any help would be greatly appreciated. Thanks

Hey Tracy,
That is exactly what I was talking about in a previous post
you replied to
http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?catid=585&threadid=1344350
Anyhow, Below is some code I created to do what your saying
somewhat dynamically. The idea being you can have many different
object types that you may want to populate with data from XML. In
my case I am using e4x as the result type from my web services. At
present I have about 6 different classes that call this function.
I'd love to get some opinions on the function. Good bad or
???? Any improvements etc????

Custom class type for Plant material

Is there any way to create a custom class type for plant and material? Any other way to use standard functionality to use classification in material master for specific plan will also work.
thanks,

Hi Rahul,
The Classification data in material master can only be maintianed at Client level and not at plant level.
The standard Class type 001 can be used to create your own classes. Create a class for each applicable plant. Add the applicable characterstics under every class. That way you will be able to maintain plant spceific details when you are adding Objects for the material master.

Creating a Custom event for my Component

Hi All,
im currently working in a swing component, and i would like to know how to give to my component the ability to react to some user changes.
Basically im creating a DateTime Picker using NetBeans, im able to see any new property justed created on the Property Editor but i would like to know how to add my custom events on the Event Editor as well, i.e:
monthChanged - (when the user just change the month dropdown)
yearChanged - (when the user just change the year box)
dayChanged - (when the user just change the selection day)
Thanks in advance

Thanks, i just found it also here:
http://www.exampledepot.com/egs/java.util/CustEvent.html
i need to define the following class:
- Custom Listener extending the EventListener interface
- Custom Event extending EventObject class
and then finally add the corresponding:
addXXXListener
removeXXXListener
fireXXXEvent
in my component.
This work Great in the NetBeans GUI Builder.
Thanks,
