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?
View 1 RepliesI would like to have a spark datagrid that wordwraps all rows where relevant. At the moment it appears like the width of a cell is dependent on the contents of the first row and then subsequent rows are word wrapped. For example:

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?

Canvas.addChild() insists any DisplayObject added implements IUIComponent. But I don't want my core graphics engine dependent on Flex. Is there an obvious/common way around this, to have simple graphical objects like Sprites & Shapes in a Flex application?

Not sure if Canvas is the most appropriate container, perhaps Group or another class is optimal for a game-engine... example MXML & AS3 code showing a skeleton setup is most welcome. I'm targeting Flex4 & Flash 10, but Flex3/Flash9 solutions are still of interest.

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 am trying to create my first real world Flex application. I will have a lot of different data entry / data view screens so I thought I would create many different components to deal with each different type of data that was being returned. I have a MXML application called Layout, and have component called "Navigator" which controls the menu, as well as a ViewStack called "MainContent".
I want the Navigator component to change the ViewStack on the Layout application to that of another Component (each Component is embedded within the Canvas of each ViewStack). I have a click handler on my Navigator which looks like this: Layout.ContentFrame.selectedChild=event.itemRenderer.data.clickValue; However it shows the error "Access of possibly undefined property ContentFrame through a reference with a static type Class." Is my approach a good way of doing it? I have attempted referencing it using FlexGlobals.Layout and topLevelApplication.Layout... neither of which work?[URL]

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

How do I say an MXML component is inside some package? Well, it's in a different folder... I know how to do it ActionScript...

I am actually in the process of Architectural of our project. We have choosen Mate framework. The project is not so quite complex, but what advantages i would get over MXML when i choose Modules.
Main App - > Views - > Events - > Maps - > Services [PHP or Java]
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.
Main APP - > Modules - > Module Interface -> Events - > Maps - > Services
[PHP or Java]
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?
In our flex application we have tabs at the main level and under it we have subview.e.g
Home / Tasks / Admin etc...
In one condition we have to click on a button and open a new tab, on this tab we have to add an existing mxml component and show it in the tab.We are using parsley as the framework. Inside the mxml component test.mxml(that is shown in the tab) i am configuring it with parsley using the tag.Now when i add the instance of this test.mxml i am getting an exception. I am deriving this test.mxml instance using teh parsley context
as
context.getObject(id of component) as DisplayObject and adding it to the tabNavigator...
But i am getting exception when i try to grab an instance of a view using parsley context. How do i get an instance of a view or component that is configure through parsley using the parslye context.Also the problem is occuring becuase of the view injection..because i get a parsley excepiton on startup of the application stating that there is some problem in the context.
i want to implement this.archive/flex/tourdeflex/web/#docIndex=1;illustIndex=0;sampleId=0)type of structure in my application.how can i display different component in differentparts.

View 1 RepliesI'm using several custom MXML components in my Flex 4.5 application.They all use absolute coordinates to place Image, Label, Line, etc. components and are currently based on a spark.components.BorderContainer:
<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer
xmlns:fx="http://ns.adobe.com/mxml/2009" [code]....
Then I've realized, that I probably don't have to use BorderContainer, because I don't draw/need any borders around my custom components.But I don't know, what to take instead of it.I've tried taking <mx:UIComponent> (and removing <s:Layout> tag above), but then I get the error:
'Image' declaration must be contained within the <Declarations> tag since it does not implement 'mx.core.IUIComponent'.
'Label' declaration must be contained within the <Declarations> tag since it does not implement 'mx.core.IUIComponent'.
Is there some simplest possible spark "container"? And do I need a "container" at all if I use (and want to use) absolute coordinates?
I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.
