How to pass parameters using dispatchEvent.

Hello

I wrote a class imageLoader. I want to send an event to the end of the loading image in the document class where imageLoader has been initialized.

public void onLoaderProgress(e:ProgressEvent) {}

imgLoader.removeEventListener (ProgressEvent.PROGRESS, onLoaderProgress);

trace (e.bytesLoaded, e.bytesTotal);

}

public void onLoaderComplete(e:Event) {}

imgLoader.removeEventListener (Event.COMPLETE, onLoaderComplete);

dispatchEvent (new event ("loaded Image"));

imgContainer.addChild (imgLoader);

}

onLoaderComplete is the image of load complete event and onLoaderProgress is the image of loading progress event. Here, I sent an event in the inLoaderComplete event. I want to send parameters with the dispatchEvent. How can we do?

Kind regards

You can use the CustomeEvent class below to have attached to your dispatchEvent function parameters...

package

{

import flash.events.Event;

SerializableAttribute public class CustomEvent extends Event

{

public var params: Object;

public void CustomEvent (type: String, params: Object, bubbles: Boolean = false, cancelable: Boolean = false)

{

Super (type, bubbles, cancelable);

This.params = params;

}

Public Overrides function clone (): event

{

return new CustomEvent (type, params, bubbles, cancelable);

}

Public Overrides function toString (): String

{

Return formatToString ("CustomEvent", "params", "type", "bubbles", "cancelable", "eventPhase");

}

}

}

To send the event you just use something like the following, where the parameters are specified as an object...

dispatchEvent (new CustomEvent ("ImageLoaded", {param1: someValue, otherParam: otherValue}, true));

At the end of reception in the ImageLoaded handler, you can acquire the parameters to help...

evt.params.param1

evt.params.otherParam

where 'evt' is replaced by any name you assign to the argument passed to the event handler function

  • Passing parameters using ADR - 404 error

    Hi all

    I'm all new development APEX. We use the DEPT tables in the sample application oracle provided for practice.

    We currently use ADR to pass parameters, but it does not work as expected, or at all. We receive a 404 when you try to run the page.

    Objective: User enters number of Department for an article and a 'Change' event (or "lose focus", we have not yet decided) on a dynamic action fills the name field with the name of the service dept.

    Has anyone else got this error?

    If there is another method recommended, please let me know.

    Thanks for your time.

    Thanks for the answers, but we have understood the question.

    We have changed the JavaScript code as follows:

    $.getJSON ("https://apex.oracle.com/pls/apex/mfajertest1/department/"+ $x value ('P2_DEPT_NO'), function (json))

    {

    Console.log (JSON);

    $x('P2_DEPT_NAME').readOnly = false;

    $x('P2_DEPT_NAME').value = json.items [0] .dname;

    $x('P2_DEPT_NAME').readOnly = true;

    $x('P2_DEPT_LOC').readOnly = false;

    $x('P2_DEPT_LOC').value = json.items [0] .loc;

    $x('P2_DEPT_LOC').readOnly = true;

    });

    Thanks for the effort.

  • How to pass parameters to a Mac app?

    The open-a command will open a mac application, but when I try to pass parameters, it is interpreted as a file for this application to open instead of the application settings.

    If I try to open the application without using the command open, it fails.

    Any ideas?

    I think that the settings should follow the switch - args:

  • Pass parameters using SFWLoader

    I need to load a SWF (AS2/AS3) go in an AS3 SWF and pass parameters to the child. It works fine using FlashVars when loading a SWF from JavaScript. Now, I need to do the same thing with a Flex2 SWF file.

    I read several posts where people succeed in passing a flex application settings 2 to the SWF, using SWFLoader. I spend a day trying to get this to work but not luck. Read a lot of forum posts and some people claim that it works for them.

    The following code is an example. A swf file that loads again all showing the parameters in a label. If you run this in a browser with "test.swf? var1 = hello-world"then it shows well-Hello everyone in the label. Click the load button and it is supposed to load the same swf with another parameter var1. The SWF file loads well but CCET times that the label is empty. The query part of the URL that contains the settings seems to be ignored. What I'm doing wrong here?

  • How to pass parameters/field values from one screen to another screen in blackberry

    Hi all

    I have two screens in my Application UI that is, login screen and continue the screen.

    Login screen has some fields of seizure as a user name and password and default language (French or English) for the application (Group of radio buttons).

    There is a button for the next who directs the user to another screen.

    This second screen has an input field. This input field is mandatory. The user can only go further if it is entered in this field of entry with valid values (i.e. numbers only).

    This screen has continue button so that the user can go further is on the next screen after you have entered a valid value in the field.

    Now, when the user clicks the continue button on the second screen so I have to validate the credentials of the user, he has provided in the first screen. Also, I need set the locale for the language he has provided to the login screen.

    So, to summarize.

    (1) user enters user name, password and language on the first screen. The user clicks NEXT and goes to the second screen.

    (2) on the second screen, the user enters a name click continuous. ((3) user credentials are validated, defined locale and user is illustrated below third screen).

    So, my question is how do I access username, the password, the language of the first screen in the second screen fieldChanged method?

    fieldChanged second display method will be called when user enter a value class we second screen and clicks continue.

    Please advice

    Thanks in advance...

    Store text values in the fields in your application class, and then pass it as a reference to each form or retrieve your instance of UiApplication and cast to the name of your class.

    public class MyApp extends UiApplication {   public String username;   public String password;   public String language;
    
    }...
    
    // Your first screen
    
    public class MyFirstScreen extends MainScreen {   private MyApp _app;
    
       public MyFirstScreen()   {      _app = (MyApp) UiApplication.getUiApplication();
    
          // Set your fields      // AS AN EXAMPLE, you can use:      // _app.username = field1.getText();      // _app.password = field2.getText();      // _app.language = field3.getText();   }}...
    
    // Your second screen somewhere
    
    public class MySecondScreen extends MainScreen {   private MyApp _app;
    
       public MySecondScreen()   {      _app = (MyApp) UiApplication.getUiApplication();
    
          // Access your fields      // you can use:      // _app.username      // _app.password      // _app.language   }}
    

    Now, this is one of the many ways to do it, but it works in its simplest form.

    You do this using global variables.
    You set the global variable in the form of call.
    And then you use the global variable in the form called.

    All this can be done by using customizations.
