1) create new canvas on top of ur application with height and width equals to application's height and width , also keep the alpha=0
now addchild your popup component on canvas.
while removing popup dont forget to remove canvas too :)

5) include following code in to ur .html file

       <script language=JavaScript>
          function refreshPage(){
          window.location.reload(true);
           }
      </script>

  and ur application will call

getURL("javascript:refreshPage()");

or you can simply use

navigateToURL(new URLRequest("your app url"),"_Self");

this will reopen the application too

Answer 2 :  Proof of Concept


Make a separate MyEvent class with the property "type" in it, you can also add more.

Make a singleton class, take an array or Dictionary variable (eventMap).

Define three functions.

dispatchEvent(obj:Object):void
{
     var handlers:Array = eventMap[obj.type];
     for each (var fn:Function in handlers )
     {
          fn();
     }
}

addListener(evenType:String, handler:Function):void
{
    if(eventMap[eventType])
    {
        eventMap[eventType].push(handler);
    }
    else
    {
        var tempArr:Array = new Array();
        tempArr.push(handler);
        eventMap[eventType] = tempArr;
    }
}

removeListener(evenType:String, handler:Function):void
{
     var tempArr:Array = eventMap[eventType];
     if(tempArr)
     {
        tempArr.remove(handler); // logically
     }
}


But for all the event handling you need to use the Singleton Object.
Eg.

singleObj.dispatchEvent(...);
singleObj.addListener(...);
singleObj.removeListener(...);

Answer 4:

I am not sure whether this is the correct answer or not, but Module can also be treated like a RSL.In one module you can make just common components and can refer them in other modules.
And each module is .swf in itself, so logically, it can be treated as a RUN time library.

5 ) call from anywhere in ActionScript:

flash.net.navigateToURL(ownReloadingUrl, “_self”);

4)

how to create a swf

a) get your swc , open it with your favorite zip extractor (may be winrar / 7zip.. or what ever you like) , extract library.swf

b) run the optimizer with flex command prompt on the extracted swf,
here
{FLEX_SDK}\bin\optimizer -keep-as3-metadata="Bindable,Managed,ChangeEvent,NonCommittingChangeEvent,Transient"
-input {PATH}\library.swf -output {PATH}\output.swf

c)get the output.swf if you need you can rename it to myNewlyCreated.swf :)

d)  run the digest tool to update the SWC digest information since the RSL has been modified. and you are ready to use.
note each update will need the whole process redone.

use

you can run  mxmlc main.mxml -runtime-shared-library-path={path} \ {swf}

where application would be able to load the library on runtime,

if you want you can add a fail over with cross-domain for give privileged o load the fail over one

mxmlc main.mxml -runtime-shared-library-path={path} \ {swf}
 -runtime-shared-library-path={swf},{path-this can be a url} ,
//next is the fail over url with cross-domain
http://a.com/path/crossdomain.xml,{swf}


3) beats ..me :-)

2) even all the

• spark.events.*

• mx.events.*

• flash.events.*

 extend the flash.events.Event class, so unless a POC like Vaibhav suggested [i must say that is good  sketch , and in oder to use it we may have to add bubbling, may be a way to inform all the parents and check weather they listen to that specific event  ],apart from that im not sure whether its  possible (*thinking..*)...

i would really love know if somebody knows how to do this....
any interviewers....who raised this question happens to be in the list ..anyone ;-)
[but this will be like reinventing the wheel]

1) most probably a method like manish's :)

Hi,

 

Answer-1 Use TitleWindow class instead of PopUp, and its done.

Answer-2 Create a local instance of the base-class(dont inherit the class, but make a instance of that in the active class), and than set the META-Data for that, and finally apply the dispatchEvent(), with the parameters....it done.

Answer-3 Use CrossDomain.xml to by pass Sandbox security.

Answer-4 --no idea--

Answer:5 this.refresh() (using AS-3)

 

I would like to thank you, for sharing some such good questions and i request all of the mates(community-friends), to share (if any) such good-experiences.

 

Regards
