There are lots of examples of how to create skinnable components in AS3 using the new Spark component architecture, however I've yet to find any such examples using MXML.What I'm mainly referring to is defining the skin parts and skin states. It seems as though the SkinPart metadata is supposed to be associated with properties and as such can't be used in MXML, is this correct?

When i come up with Modules based Architecture, it seems to be good but i doubt it should not end up with tight coupling and unwanted issues which may break the head later to solve.

What advantages i do get if i choose Modules over MXML Component? What is the prefered and the best way to Architect an FlexApplication? Since the Application is going to communicate with Backend, do we need to make the frontend more complex?

I am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
What I'd like to do: create an MXML component with some children, then extend it via MXML to create a new component with more children, without losing the original set.In other words

<s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009"

I'm trying to create simple custom component with two labels with this MXML:
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="250" height="30">
<mx:String id="result" />
<mx:Label x="5" y="7" id="titleLabel" text="{label}" width="120"/>
<mx:Label x="125" y="7" id="resultLabel" text="{result}" width="120" textAlign="right" color="#A41D00"/>
</mx:Canvas>
It is working well at runtime, bud I have troubles making it working at design-time. How can I make databinding work at the design time? If it is impossible, how should I code the label text assignments?

View 1 RepliesI'm working on an AIR project in Flash Builder 4. My question has apparently been asked a lot (according to Google), but I haven't found a satisfactory answer so I'll be very detailed in what I'm looking for:Is there any way to create an AIR project in pure ActionScript that:Is truly object-oriented (i.e. the entry point is an ActionScript class with instance variables and methods)?Can instantiate mx and spark controls without MXML?I was able to accomplish #2 in fairly different ways by following these two sets of instructions (with only a tiny bit of initial MXML):
[URL]
However, neither of those allows me to accomplish #1. If I declare a private member variable outside the entry point function, I get an error from the compiler that the keyword 'private' can only be used in a class.If you like MXML, feel free to post your viewpoint as well. My reservations revolve mostly around these perceived notions:The learning curve of MXML seems steep.The time it will take to become good at MXML will not be worth the investment since its main purpose is to ease GUI development (which I'm already good at anyway).Like I said previously, I don't want to be an "XML programmer". I'd like to maintain the power and flexibility of OOP.
I have several mxml components in an app, all of which need the same variable called genericX. I've included that variable in the main mxml and made it public
[Bindable] public var genericX:Number = 102;
But I still can't access it from other mxml components. If I try to do this for example, it doesn't recognize the variable.
<s:Button x="{genericX}" label="Click" />
When I define custom propertie in my MXML component, I also want to define a set of possible values of that property to make Flex Builder show then (possible values of the custom property) when I invoke code completion function.

View 2 Repliesim trying to figure out what is better for run-time, creating components in MXML or by SCRIPT?. I built an app that recieves data from a server without knowing how much data exactly. In worst case scenerio , ill need 10 LABELS and 2 DATAGROUPS.But i usually need something like 3 LABELS and 1 datagroup. what is better? creating all components in advance and than not include in layout the ones i dont need, or make some checks and then create only the components i need by script? I made some tests , but it wasnt really decisive, run-time was pretty much simillar.Im guessing it must be stated somewhere what is better. Does anyone have an answer for me?
View 1 RepliesI have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
View 4 RepliesI would like my spark ItemRenderer to be able to render a varying number of graphical objects that depends on the user input. As an example, let's say that I want to render a set of ellipses on a line.I've been using MXML for my most recent batch of ItemRenderers and have loved every minute of it, but I'm not sure how to accomplish the above goal with an MXML IR. In Actionscript I can acquire the list of ellipses locations and draw them programmatically in the updateDisplayList method. Is there an equivalent in MXML?
View 1 RepliesI'm using Flash Builder and created a spark-application Flex project that will stream video from the local camera. If I use mx.controls.VideoDisplay; there is no problem since it has attachCamera(camera) method. But Spark's VideoDisplay component does not have that method. I know I can use mx controls inside a Spark app but I want to know:
What is the real difference between spark.components.VideoDisplay and mx.controls.VideoDisplay?How do I attach camera to spark. components.VideoDisplay?Is there any advantages if I go with spark (since it's newer to mx library)?
EDIT: In the documentation this is mentioned: "Starting with Flex 4.0, Adobe recommends that you use the spark.components.VideoPlayer class as an alternative to this class. (mx.controls.VideoDisplay)"

How can Application's ControlBar be moved to its bottom in Flex 4.5 ?
The Adobe doc says only:
By default, the ApplicationSkin class defines the control bar area to appear at the top of the content area of the Application container with a grey background. Create a custom skin to change the default appearance of the control bar.
So I look at spark.skins.spark.ApplicationSkin and there is a controlBarGroup (does it hold the ControlBar contents?), but I don't know how to move it from top to the bottom.
I'm creating a log-in box for my Flex application. However, I'm required to apply a specific design to this box that I have to change the title bar height.
