post a custom event to trigger the listener

• Using the simple custom event

  I try to get a better understanding of the events and to create my own custom events and calling dispatchevent. This is in reference to a previous post here: http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=60 & catid = 585 & threadid = 1329712 & enterthread = y
  
  Initially, I tried to get this working in the middle of a bunch of other things going on but could not get my disptachevent to trigger the listener that I had put in place. After messing around for a while, I decided to just pull this part out and try to get the basics of this work (I always have problems with). While I can find a lot of examples, listeners in action out of events predefined (such as mouse clicks) can't get a lot about what I'm trying to do. I don't know I am missing a simple property of the events and making a call wrong here but I can't understand what it is.

• What is the custom event that fires?

  Hello
  
  What is customized event triggered in the OPA.
  
  I heard that, at the time of the training online OPA in last week.

  A custom event is a way to write a rule that will send a signal. When executing time event listeners can be attached to the motor of the OPA, and a custom event can be used as a way to signal that something should happen.

  For Documentation on writing a raiseevent rule see rules of use to trigger external software applications in modeling of political Oracle Help.

  For Documentation on the event listeners, see events and event handlers and example: handle the events of modules with an inference event listener in Oracle policy Automation Developer Help.

• Custom events

  Hello

  I want to trigger an event to a class and listening to the other.  There are several examples on the net but I don't really understand them.  Can someone explain please how can I get the value of newTextInput in the lower class on the evolution and pick it up in another class.

            public function changeHandler(event:Event):void{
                 
            }
            
            //  Creates a text input 
            public function setText(label:String, type:String, id:String):void{
                 var newFormItem:FormItem = new FormItem;
                 var newTextInput:TextInput = new TextInput;
                                
                 newFormItem.label = label;
                 newTextInput.id = type;
                 newTextInput.text = id;
                 newTextInput.addEventListener(Event.CHANGE, changeHandler);
                                
                 this.addChild(newFormItem);
                 newFormItem.addChild(newTextInput);                                   
            }
  

  This is the class I want to get the value of newTextInput:

  package components{
       
       import mx.controls.TextArea;
            
       public class KamTextArea extends TextArea{
            
            public var label:String;
            public var required:Boolean;
            
            public function KamTextArea(){
                 label = "Null";
                 required = false;           
                                
            }
  
            public function setupProperties(propertyInstance:PropertiesForm):void{
                 
                 propertyInstance.setText('Label','label',this.id);
                 propertyInstance.setBool('Required', 'required');

  Thank you

  You need to understand the basics of the custom events, please read the Adobe LiveDocs page:

  Ching http://www.google.com/search?hl=en&q=Flex+3+dispatching+Custom+Events&AQ=1&OQ=Flex+3+dispa & AQI = g2

  So create a custom event and make the event type 'myEvent '.

  Can have a property of the custom event to the value of newTextInput.

  Your other class listens for the event and accessing the property of the event object that contains the value ofnewTextInput.

  You may need to add the event listener to systemManager:

  systemManager.addEventListener (MyCustomEvent.MY_EVENT, myHandler);

  My post Cookboo Flex deals with custom events. It's a bit long, but if operate you locally, it can clarify certain points.

• Several components are listening to the same custom event?

  I tried to make the transition from Flash to Flex and I've been struggling with this one for the last two days. I used to do a lot of SEO _root.moviecontainer.mylable.text, but I'm trying to get the idea of demonstrations, dispatchevents, etc. down and get SEO for Flex to manage. The simple explanation of what I'm trying to do is to have a component triggers an event and either dynamic broadcast to all components that subscribes to this event (the number of components listen to will change during execution and so I don't want to directly refer to these objects). I would like to be able to generate other objects during execution and to associate them with this event dynamically. I tried to add an addListener (customEvent) to listen to the dispatchevent(), but I had no luck with this method until now. Raises the event, but I can't understand how to associate other components with it. I guess that having only three parts to it: the component that triggers the event, the event itself (custom) and the component that is listening for the event. And none of the components know anything of the any of the other components that exist. The trigger could be raising an event 3, 10, or 100, other components are listening, but he doesn't know how many elements are tuned, nor she cares & maybe even wait for one component which is capable of raising the event, he is listening the listening component, or there could be a total of 10 components capable of triggering this event. If you did it at the end of the present, thank you. This has been a headache for me, and I'd appreciate any help offered. Thank you.

  iTextArea is a brother of iButton and isn't in its parent chain, so it will not be a propagated event.

  Perhaps you could put a Manager in the Application that redistributes events and listen for them in iTextArea.

• Custom event is not captured by the Task Scheduler and unable to trigger by e-mail for the event

  Hello world

  We have installed the 9.0 table in our windows 2008 R2 server and Scheduler tasks to send if you find error occurred for the application in it. That's why we created SMTP inside. First, we have implemented the Task Scheduler and generate an error in the application of the table and run the task manually and we receive by e-mail. But when we go for automation by the custom event. The steps below that I follow:

  1. click the Start button, and then select administrative tools > Task Scheduler.

  2. click on the task of creating in the Actions pane on the right.

  3. in the dialog box create a task in the name text box, type a name for the task and provide a description if you want.

  4. in the section security options, select run whether user is logged in or not.

  5. click on the triggers tab, and then click the new button.

  6 to start the task drop-down list, select an event.

  7. in the settings section, select custom and click the new event filter.

  8. for the event level, select the error box.

  9. selection of the Source, in the event source drop-down list, select the table server checkbox.

  10. click OK to close the new dialog box even filter and then click OK again to close the new trigger dialog box. The event trigger is now configured.

  11. in the dialog box create a new task, click the Actions tab and click the new button.

  12. in the Action new dialog box, in the drop Action, select send e-mail.

  13. under the settings section, fill in the form as required, including the SMTP server.

  Note: It is necessary to enter the valid e-mail addresses in the From and to text boxes.

  14. click OK to close the new dialog Action.

  15. click OK to close the dialog box create a task and finish configuring e-mail alert.

• Custom event listener callback fails

  Hello

  I have a mobile project Flex 4.6 and I created a custom event, I can see different tracks that the event is currently distributed as planned, but no matter what I do I cannot get a listener to the work that they just sit there and nothing ever happen, please take a look and tell me what might be wrong.

  Custom event:

  package classes.events

  {

  import flash.events.Event;

  SerializableAttribute public class cartLoaded extends Event

  {

  public static const = "cartLoadSuccess" CART_LOAD_SUCCESS:String

  public void cartLoaded (type: String, bubbles: Boolean = false, cancelable: Boolean = false)

  {

  trace ("event_dispatched");

  Super (type, bubbles, cancelable);

  }

  override public function clone (): event

  {

  trace ("event_cloned");

  return new cartLoaded (type, bubbles, cancelable);

  }

  }

  }

  The event is dispatched to a class, after a ResultEvent returned by a Web service call, so in the ResultEvent reminder I have:

  var cl: cartLoaded = new cartLoaded (cartLoaded.CART_LOAD_SUCCESS);

  e.currentTarget.dispatchEvent (cl);

  And I see "event_dispatched" in the console when my results come back. So, I know that the event is triggered. Now on the file of main Application in the ViewInit on a list, on a view that I add, I have almost tried this anywhere.

  lst_cart.addEventListener (cartLoaded.CART_LOAD_SUCCESS, LoadData);

  function loadData(e:cartLoaded):void

  {

  trace ("data set provider");

  }

  I never see "set the data provider, now I understand that the listener must be saved before the event is dispatched, and in my case, it certainly is:

  I have a vision (tried to addEventListener here in an initialization handler)

  the view contains a list with a custom converter (tried here)

  the itemrenderer contains a button (have tried here)

  the button calls a method in a class that raises a web service call (this is where the event to send)

  the web service call triggers a result event

  the result event is triggered my custom event

  Please help, because it is seriously holding me back, I have to be able to capture this event, and I've tried everything.

  Pauleta is true that there is a loss in the case of the chain, like the wrapper it cannot listen on the list because the list itself is not part of the hierarchy of the event.

  I think you can get around this in two ways.

  1. Have your Cart class extend the EventDispatcher class. If this is not possible at least implement IEventDispatcher interface and have a composite object that is the event dispatcher. Anyway, given the class cart is a form of an event dispatcher.
  2. Have your item converter listen directly to the event on the Cart class.
  3. Your event handler converters, to ship another event that spreads to the top of the display object hierarchy.

  Something like this:

  public class Cart extends EventDispatcher
  {
       public function doStuff() : void
       {
            ...
            dispatchEvent(...);
       }
  }
  
  OR if you can't extend it
  
  public class Cart implements IEventDispatcher
  {
       private var _eventDispatcher:EventDispatcher;
       //contains all the methods of the IEventDispatcher interface but uses a facade layer
       public function Cart()
       {
            _eventDispatcher = new EventDispatcher();
       }
  
       public function addEventListener(params...) : void
       {
            _eventDispatcher.addEventListener(params...);
       }
  
       public function doStuff() : void
       {
            ...
            _eventDispatcher.dispatchEvent(...);
       }
  }
  
  public class MyItemRenderer
  {
       public function buttonClick() : void
       {
            var cart:Cart = new Cart();
            cart.addEventListenerer(...);
            cart.doStuff();
       }
  
       public function doStuffEventListener(event:Event) : void
       {
            //Make sure the bubbles property is set to true
            dispatchEvent(event.clone());
       }
  }
  

  This should ensure that the event now on the queue from the list view... If she is probably not a good idea to constantly be adding some that this event listeners, it is probably better just to have a callback function and pass it to point converters to pass based on the cart process.

• Components customized QML: management of the events of the child controls

  The tutorial here:

  https://developer.BlackBerry.com/Cascades/documentation/UI/custom_components/custom_components_tutor...

  Shows how to use the alias so that you can read the values of the properties of the child controls.

  It would be good to have a code example that shows how to hang children change events. For example, if your custom control has a control segment, how to make the custom control user be notified when there is a click on segment control event or when the value of this control is changed.

  Signals can be easily created in QML and exposed from a QML file that is customized to be listend to another. The following article explains the basic process:

  https://developer.BlackBerry.com/Cascades/documentation/UI/signals_slots/index.html

  In its simplest form, a signal is created in QML using the following format:

  signal signalName (variableType variable1,...)

  In the QML implementation of this custom control file, you will now have a manager of signal onSignalName created automatically for you.

  I covered this topic in my last webcast and created a sample file that looks like this:

  https://developer.BlackBerry.com/Cascades/documentation/videos/index.html

  Beta 1: Astonishing UIS using the new framework of BlackBerry 10 - part 2

  The sample was created against the Beta 1 of the NDK for BlackBerry 10 but the QML (TaskControl.qml) file should work fine in the beta 2 release. If you are having trouble please post it here and I will consider.

• Custom with the custom event handling/propagation class

  Hello

  I m trying to figure out, how we could extend a custom class so that other classes could enter the headphones to this custom class

  and will be informed by raising an event in this custom class.

  I can´t find any documentation about it. The post of oracle on the management of the event to

  http://docs.Oracle.com/JavaFX/2/events/jfxpub-events.htm

  doing business only about the event target and the string of events.

  But to my understanding, I need to know how this custom class could be extended to be an EventSource?

  I could extend my node, scene or window class to get all the things in the event by legacy, but I think that

  that is not the right way? Not everything is a node

  As indicated in the article

  If your control or element of your control is not a subclass of Window , Scene , or Node , you need to implement the EventTarget interface for this control or element.

  I must apply EventTarget and its method

  @Override
      public EventDispatchChain buildEventDispatchChain(EventDispatchChain edc) {
          throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
      }
  

  But it is a target? And the source?

  I m a bit confused.

  Help would be great for a beginner, some shooting events

  THX

  Inge

  Would what type of event you like fire? Perhaps using the framework of the event in javafx.event is more you need. What if all you want to do is to inform listeners that some State has changed, you should consider using javafx.beans.Observable or one of the classes implementing this interface.

• Management of the custom event sent by loading SWF fails

  I loaded and SWF using SWFLoader. Not a component, but just a regular Flash AS3 SWF. I can access its properties and functions but when I listen to a custom, event distributes, I get the error:

  Error #1034: Type coercion failed: cannot convert com.subhumanmedia.classes::SoundCueEvent@911ad61 to com.subhumanmedia.classes.SoundCueEvent.

  Here's the event:
  package com.subhumanmedia.classes
  {
  import flash.events.Event;
  SerializableAttribute public class SoundCueEvent extends Event
  {
  public static const = "cueSound" CUE_SOUND:String
  
  private var soundCueObjectInstance:Object;
  
  public void SoundCueEvent (type: String, bubbles: Boolean, cancelable: Boolean, soundCueObject:Object)
  {
  parameter soundCueObject:
  soundCueObject.cueSoundURL is the string with the name of file to play
  soundCueObject.cueSoundStartTime is the number giving the millisecond offset to read from
  //
  Super (type, bubbles, cancelable);
  soundCueObjectInstance = soundCueObject;
  }
  public function get soundCueObject (): Object
  {
  Return soundCueObjectInstance;
  }
  override public function clone (): event
  {
  return new SoundCueEvent (type, bubbles, cancelable, soundCueObjectInstance);
  }
  }
  }

  Here is the statement in the loaded SWF, the event:
  dispatchEvent (new SoundCueEvent (SoundCueEvent.CUE_SOUND, true, false, soundCues [cueCounter]));

  
  soundCues is an attay soundCueObjects.

  Here is the definition of the listener in my main class:
  slide.slideGraphic.swfObject.content.addEventListener (SoundCueEvent.CUE_SOUND, cueSoundHandler);

  And here's the Manager:
  private void cueSoundHandler(e:SoundCueEvent):void
  {
  trace (e);
  }

  If I change the type of parameter of the event Manager, it does not take a mistake, but I can't yet ride a SoundCueEvent event in order to obtain tracking information.

  Now both the right loaded SWF and main class get the definition of the event from a compiled SWC, but I tried several other ways to do it without any better result.

  I don't know even what causes the error and am totally baffled by how to solve it. Can anyone help?

  It is equivalent to the problem of shared code described in the presentation of the modules on my blog.

• Event Bubbling: Relay of the custom events

  Background:
  The bubbling in the action script 3 event causes an event to travel from the responsible subject through all its objects from parent to the root application. The event then moves back down to the original object.
  
  Goal: keep the data, the controller and the loosely coupled views
  1. When display objects are instantiated, they send an event by saying that they need certain information. The event has the type of information they need.
  2. the purpose of data capture this event, determines if it it has in memory. If it isn't, it retrieves information from a web service and pushes the result in a table.
  3. once the result in memory, it takes an event that contains the index of the result table.
  4. the view captures the result, out of the index and use it to link to the correct array element
  
  Result: The display is automatically updated every time that the data object is called by the web service with an update.
  
  In this scenario, nor the view or the data can be parents of each other, but each must be able to respond to the events of each and other. The reason is so that I can have multiple views generated dynamically, using the same data.
  
  Question:
  If the data (model) and the views are children of the same application, how does one maintain loose coupling between them?
  
  Current solution:
  The only thing I could get to is having the object application or controller catch all custom events and then their reconsignment to the children. The problem is that it is messy.
  
  I could also design a handler class that would have the forwarding of events to the right of the child hierarchy. I could include a private string variable that would capture the name of the object responsible for when my custom event was known as the class handler could do dynamic mapping.
  
  Is there a better solution?

  Thanks - I posted the question on something awful and someone suggested that I use a microwave recommended architecture on Adobe Labs called Cairngorm , I'll go through the documentation and give it a test drive this week.

• Is it OK to trigger 2 loops of event out of the same control?

  I have two circuits of event that will trigger when the user click on the Exit button. Is this ok to trigger the two loops off the coast of the same order? It works fine, but I don't know if there could be a problem. Please see below. Thank you!

  Perhaps another point I have wired 50ms to the timer of the event MENU structure and want any delay in the structure of the MAIN Event. Not sure if it is a valid argument.

  I recommend spending your menu commands in your main event loop.  You'll thank yourself later.

• How to trigger the value change in the structure of the event

  HII everyone, like the title, how should I trigger the value change event to display a message... Here is my connection... I want to trigger structure of the event to bring up the subvi, when the flame and the led are TRUE State... I have using the node property, but still not able to run event structure... How should I connect? Thank you very much...

  There are several ways you can do. First of all, you need to configure your sub - vi while he does everything you want when you run (in the properties of vi, top most window for example) and to make sure that it closes completely when you're done (when you click on the 'OK' button, for example).

  Spend you need an asynchronous call to the subvi. There are several ways to do so. My favorite one below. You go in the palette under 'Application control' and select a static reference VI. I like this approach because it keeps track of the way subvi for you, as long as the subvi is in the same project. Then, drag the sub - vi on the empty square which will be changes to your sub - vi icon. Then, you connect to an invoke node in the same palette under and select run VI. "Wait, that 's" set to false and the main VI will continue to function after the start of the vi of Sub. Together "Auto Ref" is the best way to go. Otherwise, you will need to follow the sub - vi reference and shut up yourself when you are finished.

  

• How can I remove selected Custom view (s) of the event viewer Console tree?

  I looked at the MMC Help on create and manage custom views.

  I can't find a way to remove the custom filter views in the Console tree, which can be found on the left side of the event viewer.

  How can I remove selected Custom view (s) when they serve no more values?

  Problem solved

  I asked this question because I was unable to see what was going on in the event viewer and I couldn't find help in mmc HTML Help. However, now I see what's happening and I can give you a solution to my own question.

  Cause

  If I connect to the computer as a user with administrator privileges, I am able to use the event viewer to create a custom view filter that can be used by all users who have access to the event viewer. If I fix remove a view filter custom Console tree, I can't delete it unless I'm logged in as the user who created it.

  Solution

  1. Log the computer as the user who created the custom view.
  2. Start Event Viewer
  3. Use the right-click of the mouse on a custom view filter selected in the Console tree, open the drop down menu.
  4. Delete appears fourth in the bottom of the menu if and only if you are logged on as the user who created this view.
  5. Select Remove to remove the filter to custom view.

  If Delete does not appear in the drop-down menu, then it may not possible you connect as the user who created the custom view.

• Box state to read option after another event of the listener

  I know that it is something very simple, but I'm still a little fuzzy on the scope of the fields & methods.  I want to read the State of a radio button after another event to the listener.  I did a work around, but I don't know that there is a much better way.

  Code:

  / public final class SelectionScreen extends screen
  {
  public boolean selected;
   
  public SelectionScreen()
  {
  Initialize and configure the title bar
  Super (MainScreen.VERTICAL_SCROLL |) MainScreen.VERTICAL_SCROLLBAR);
  setTitle ("choice screen");
              
  create and add radio buttons for the selection of the screen
  RadioButtonGroup screenGroup = new RadioButtonGroup();
  RadioButtonField screen1Field is new RadioButtonField (Goto screen '1', screenGroup, true, RadioButtonField.FIELD_RIGHT);.
  RadioButtonField screen2Field = new RadioButtonField ("Gogo screen 2", screenGroup, false, RadioButtonField.FIELD_RIGHT);
  Add (screen1Field);
  Add (screen2Field);
      
  I would like to remove this code...
  selected = screen1Field.isSelected ();
      
  screen1Field.setChangeListener (new FieldChangeListener() {}
  {} public fieldChanged no (field arg0, int arg1)
  selected =! selected;
  }
  } );
  down here and use the isSelected inside the button1Press() method
             
  ButtonField buttonField_1 = new ButtonField ('Next', ButtonField.CONSUME_CLICK |) ButtonField.FIELD_HCENTER);
  Add (buttonField_1);
                    
  buttonField_1.setChangeListener (new FieldChangeListener() {}
  {} public fieldChanged no (field arg0, int arg1)
  button1Press();
  }
  } );
  }
    
  private void button1Press() {}
  I would use the next line here
  If {(screen1Field.isSelected ())}
  If {(selected)
  Dialog.Alert ("goes to screen 1");
  } else {}
  Dialog.Alert ("goes to screen 2");
  }
  }
  }

  Just make your RadioButtonFields of the private members of your class so that you can access them from anywhere within the class. That is to say:

  private RadioButtonField screen1Field;

  public SelectionScreen()
  {
  Initialize and configure the title bar
  Super (MainScreen.VERTICAL_SCROLL |) MainScreen.VERTICAL_SCROLLBAR);
  setTitle ("choice screen");
              
  create and add radio buttons for the selection of the screen
  RadioButtonGroup screenGroup = new RadioButtonGroup();
    screen1Field is new RadioButtonField (Goto screen '1', screenGroup, true, RadioButtonField.FIELD_RIGHT);.
