Custom event

I need to communicate between two different controllers associated with different sections to FXML.

I create a custom even and put implement an event handler in one of my controllers.

I can't understand how to raise the custom of my other controller event. So far the documentation I've found don't fill empty on an event from a controller or even a class other than that already .fireEvent as a member of shooting.

I use the wrong design template here or there at - it an easy way to trigger an event?

Nickname
public class myEvent extends Event {

     private static final long serialVersionUID = 1261846397820142663L;
     
     public static final EventType<myEvent >MY_EVENT = new EventType<myEvent >(ANY, "MY_EVENT");

     public myEvent (EventType<? extends Event> arg0) {
          super(arg0);
          // TODO Auto-generated constructor stub
     }

     public myEvent () {
          this(MY_EVENT);
     }
}

public class myClass implements EventHandler<myEvent> {
     @Override
     public void handle(TimelineDropEvent arg0) {
          // TODO Auto-generated method stub
          System.out.println("MyEvent");
     }
}

public class myOtherClass {
//TODO what do I do here to fire an event
}
Of course the two of my examples of classes also implement Initializable since they are controllers.

In my case I absolutely need serialVersionUID or y at - it another way to avoid the warning associated with remove?

Sorry for the delay. I had to create a project in Google Code to host the example:

http://code.Google.com/p/sjmb/

The source code for the API message bus is here:

http://code.Google.com/p/sjmb/source/browse/#SVN%2Ftrunk%2Fsjmb%2Fsrc%2Fcom%2Foracle%2Fsjmb

Essentially, it allows callers to subscribe to "message subjects", which are simply the Java types. Any time that an instance of a given type is sent, subscribers listeners are notified. Any type of Java can be used, including enumerations, which provide a nice way and type-safe to set messages.

Here is an example that shows how to use the API:

http://code.Google.com/p/sjmb/source/browse/#SVN%2Ftrunk%2Fsjmb%2Ftest%2Fcom%2Foracle%2Fsjmb%2Ftest

The main application window has a tab pane that contains 3 identical legs. Each tab controller subscribes to a message of type com.oracle.sjmb.test.Message. Entering text in the text field and press the "Send Message" button sends a new message, causing the other two tabs update their own fields of text content.

The application of the example consists of the following files:

Message.Java - the message class
MessageBusTest.java - the main class JavaFX application
message_bus_test.fxml - document FXML containing the main stage
Tab.fxml - document FXML tab content pane
TabController.java - content tab controller

Javadoc and binary are available here:

http://code.Google.com/p/sjmb/downloads/list

  • 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.

    Post edited by: sfisher_sticky_kiwi

    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.

  • 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 are not heard or sent successfully

    Hey guys, I did experiments with the writing of my first custom event.  So I have a MovieClip class in the library called "curtains."  He plays an animation and at the end of the animation, I have the code:

    Stop();

    dispatchEvent (new Event ("closed"));

    Now, I create an instance of this MC curtains in my class below.  The custom event is not detected.  Did I put the event listener in the wrong place?  What I've done wrong?

    Add a track to your class TransitionTimer to confirm that it is used as the document class.

    Add a line to the last frame of your movieclip where your 'closed' event is dispatched.

    Copy and paste the instructions of tracing so that might not be obvious what is your problem.

  • Variables that may be related to custom events Vs

    Greetings to all...

    I'm working on an application that is too great, so whenever we can, we create custom components and classes to organize the entire procedure as good as possible.

    Today, I was working on a login form that is also a custom component.

    So, this component has a remote object to get the user to the server if the connection is successful.

    This user must be sent to other components too and also in the main application that is the parent of the connection.

    I created a custom event that is shipped to the component if the connection is successful.

    My main application is to listen to this event in order to get the logged in user.

    It's a way to do it.

    The other way would be to make two user objects can be bound and whenever the user inside the element object is ready it would change too.

    Which do you think is the best approach for what I'm doing?

    In my opinion (since I read a looooot on memory leaks with objects that can be linked) the best approach is to work with objects that can be linked only when its necessary.

    Your opinion about this?

    Binding is not prohibited, as it is a valuable element of Flex, but sometimes when you use the binding, you end up elements of hard wiring in your application, which limits your ability to code reuse more easily.

  • What is the point of having the function of the cloning in custom events?

    What is the point of having the function of the cloning in custom events? I do this, but never understood why lol

    The EventDispatcher call to clone the event when you return an event with dispatchEvent (event). It is also why you should implement it correctly (copy all properties), otherwise the listeners who handle the redispatched event will receive an event with incorrect values.

  • 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

    {
    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
    //

    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.

    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);

  • Create a custom event

    I use a class with an instance name of textParser1. After you create the instance, I want to be able to use a property of the class, but the value that is returned is appears to be back too early (i.e. before the class has finished processing completely).

    Here's what I want to do:

    textParser1 = new TextParser (content);

    trace (textParser1.someVal);

    I believe that the solution is to create a custom event, but don't know how to do this. Here's what I think I should do:

    textParser1 = new TextParser (content)
    textParser1.addEventListener(Event.???,completeListener)

    function completeListener (): void {}
    trace (textParser1.someVal)
    }

    Is that correct and can you point me to an example of the right way to do it.

  • Passing a parameter to a custom event?

    OK, I almost have this figured out, but there's always a part that escapes me.

    I have a component that will dispatch a custom event 'ImageClicked' (see code). The component instance has a string variable ' var link: String. I pass a string of binding to this element when it is created, such as the purpose, say that the value is "" http://www.adobe.com ". "

    I want to raise this event to the main application and not the value of 'link' with the event, so my request then go to the Adobe homepage (in this example).

    I then this event listener: mainStack.addEventListener (ImageClicked.CLICK, goLink);

    My goLink function expects a string parameter, the value of 'link' in the component, in this case, I wish it were " http://www.adobe.com".

    Can someone please clear this up for me? I feel like I'm so close, but it is missing a key ingredient

    Here is one approach. Let us know if this does not work in your situation.

    You must add an eventListener to listen for the event. First give an id to your custom component:

    Now you are calling a create1function that is not declared anywhere, then change the code of your application to this script:


    public void create1(): void
    {
    myForm.addEventListener ('stateChangeToEdit', stateChangeToEdit);
    }

    public void stateChangeToEdit(eventObj:Event):void {}
    currentState = "change"; I have to qualify the scope of application?
    }
    ]]>

    Try this and let me know if it worked
