So I'm using a custom auto suggest component that I found online at [url]... The background color for the item is set within the following folder[code]...
I use this component from within a component I created called "position.mxml" that is located in a folder named "modules". Is there any way that from the position module, I can change the background color of the autosuggest box?

I would like to send variables or parameters from Component to Main (MXML) Application. Like my component is FileUpload.mxml and would like to forward the uploaded file details from FileUpload.mxml to Main.mxml.
I tried the following procedure :
com:FileUpload id="fp"
to get the reference for the FileUpload component, however, I am unable to get the variables from the FileUpload.mxml file.
I need to be able to call a method from a component located under the main application in Flex 4. Can anyone tell me please how to do this without using FlexGlobals please?[code]
View 3 RepliesIn my main application I have a viewstack with 3 child views. In the viewstack change handler, I programmatically change the selectedchild property.
I understand that the initialize method for the view is not called every time I change the selectedChild Property. So I tried to invoke the init method programmatically too..

I am creating a Flex application with a component that displays various dynamically loaded SWFs, one at a time (kind of like a kiosk). These loaded SWFs are created in Flash IDE, not Flex. They will not be created by us (we will provide a .fla template but that's it), so I am loading them into a separate SecurityDomain.
My Questions:
I want the application to be able to call methods inside the loaded SWF. To do this, would I just call Security.allowDomain("domain original app was loaded from") in the startup process for the loaded SWF? I want the loaded SWF to be able to throw events that are caught by the application. Can I accomplish this through the SWFLoader.swfBridge property? I am defining an interface for the methods inside the loaded SWF. But, I don't want to leave the implementation up to the customer. Instead, I want to provide another SWF that contains the interface implementation and have it be a constraint that the customer includes it in their SWF. I am not very familiar with the Flash authoring environment, how would it work so that the interface implementation SWF exposes its methods in such a way to be accessible to Flex? Is there a way to sign the SWF so that the Flex application knows that it is dealing with the original, not a spoof? How would the Flex code pass in arguments, since it is across SecurityDomain boundary -- is there marshalling involved (say if I want to pass in a Dictionary or some kind of object graph)? The Flex application may load hundreds of these smaller other SWFs during its lifetime. How do I make sure it doesn't keep using up more memory? I plan on using SWFLoader.unloadAndStop() and clearing all references in the Flex object that refers to it. Is this enough? Will the AppDomain for the loaded SWF be torn down automatically so that the class definitions are no longer in memory?
i used systemManager.addEventListener in sub application...... it is working well....but when i load sub application into main application through swfloader it doesnot working..
View 1 RepliesIs there a way to tell at runtime if a flex UIComponent is in the user's view or not.For example, if I have a tabNavigator with a combobox on each tab, is there a property of the comboBox that will tell me if it is visible to the user or not when I switch from one tab to another?I know it is not the comboBox.visible property. That is set to "true" for both comboboxes. I want a property that will change when I switch from one tab to another making the comboBox visible to the user. I don't know what that property is.

I have an application with a SWF loader. From the loaded SWF file, I'm accessing public variables from the main application with this:
[Bindable] public var global:Object = FlexGlobals.topLevelApplication;
Alert.show(global.myvar);
This all works perfect. I have a MXML skin file (for buttons) in a directory called 'skins' in the main application. Is it possible to use this skin in the child applications?
I've already tried this, unfortunately not working:
[Bindable] public var global:Object = FlexGlobals.topLevelApplication;
<s:Button label="My Text" skinClass="{global.skins.menuButtons}" />
And this, but then it can't compile anymore:
[Bindable] public var global:Object = FlexGlobals.topLevelApplication;
<s:Button label="Button 1" skinClass="global.skins.menuButtons" />
<s:Button label="Button 2" skinClass="FlexGlobals.topLevelApplication.skins.menuButtons" />
Is it possible what I want in another way or do I have to copy the skin to the all the projects where I want to use the skin?

View 1 RepliesI'm making a UI for a component in Flash. I wanted to use Flex and have had no luck getting the onUpdate exernalInterface call to fire properly. I'm referencing the functionality described here: [URL]. First off, I can't embed the SWF in the FLA. It just won't start the Flex SWF. Even using the external swf, it seems that the onUpdate function is either called too early or not at all. Here's what I've tried:
Tying the externalInterfce declaration to the initialize, preinitialize, applicationComplete, and creationComplete events. Sub-classing my application and putting the externalInterface in the constructor. Neither of these options work. When I create a basic AS3 project in Eclipse and put the externalInferface in the constructor, it works as expected.
How do I get "close" button to run runFunction() from within component to outside declaration? FxGlobals.topLevelApplication doesn't seem to be working for this.

Im a complete beginner in Flex programming. I have an application with a main .mxml file, and a certain class Foo that I call from the .mxml. In Foo, I make a URLRequest and listen for the Complete event. Then I found myself with the returned data in a Foo function, but I have no idea how to communicate it to the .mxml part of the application ! I looked into ArrayCollections but I can't seem to understand how they work. Isn't there a way to modify, from inside the class, a variable with a global scope ?

I have an event, which I have dispatched in my main.mxml:

this.dispatchEvent(evt);
I can listen for it while in my navigation.mxml file, by using
this.parentApplication.addEventListener(UserEvent.USERINFORMATION, onInfo);
But in other component, I can not listen for it, even trying the same as I did in navigation.mxml.
tracing it back gives me an undefined.
the second component is in a viewstack in navigation.
