calling a popup by passing his name to a function

[Davide C]

Hi! I'm new to Flex.

I have created with Flex 2 popups (which are TitleWindows):

popup1.mxml and popup2.mxml

Is there a way to write a function like this:

PHP Code:
public function openPopup(myPopup:String){

//here the code to take the string myPopup (which can be popup1 or popup2) and
create the popup...
??? I really don't know how to do this

PopupManager.createPopup (this, ???, true);

}


Thanks in advance.

take a look at:
[url]http://www.onflex.org/ted/2007/11/creating-class-instances-dynamically.php[/url]

essentially you'll be using ApplicationDomain.currentDomain.getDefinition
method call as the second parameter to craetePopu method.

Thank you very much!

Just another question about this:

I implemented the popup as a mxml component in the drectory
src/popups/pop_login.mxml. And "hasDefinition" doesn't seem to work in that
case...Is there a way to do that WITHOUT implementing the popup as a class?

Thanks.

So you have it working now?

[Davide C]

Not yet.., I mean: what I have now is:

var login:pop_login=pop_login(PopUpManager.createPopUp ( this, pop_login ,
true));

where pop_login is a component. I don't know how, but Flex seem to find it and
use it as a class. But if I do the same thing this way:

var thePop:Class =
Class(ApplicationDomain.currentDomain.getDefinitio n(popUpName));

where popUpName is the filename (without extension) of the component
(pop_login.mxml , in the dir src/popups/) that I pass as string, the function
returns always false...

Sorry, I'm new to Flex, maybe it is a bit confused...

[Davide C]

No, I tried but it does not work. I don't know how to do this with mxml components. it seems that
ApplicationDomain.currentDomain.hasDefinition always returns false...

[Davide C]

What I need is just a sort of "Factory Pattern" where, according to what I pass as a string, it instantiates the class with that name.

[Davide C]

SOLVED!!!

The problem was this:
You have to specify the entire path to the MXML file:
hasDefinition("components.popups."+popUpName)
Now it works PERFECTLY!.

Thanks for sharing it back.

Just another NOTE:

The code above works ONLY if you reference the classes somewhere in the code.
I mean:

public var: popLogin:pop_login; and so on...

This is not good at all.

So my question is: how you can REFERENCE (not import) an entire set of classes
(components, actually) in a project?

Use modules.

Hi Tracy,
it does not work...maybe I'm missing something, but I have created a module
and tried to load (as popup) dinamically...but the result is the same. I have
to reference it before doing that:

public var myModule:TestModule; //This is what I would like to AVOID.

then I can use this:

var myClass:Class =
ApplicationDomain.currentDomain.getDefinition("pop ups.testModule") as Class;
var myPopup:TitleWindow =
TitleWindow(PopUpManager.createPopUp(this,myClass, true));
