ActionScript 3.0 :: Scope In MXML In Flash Builder 4.5
Sep 16, 2011
I've got years of experience with AS3 but am very new to MXML. I've downloaded Flash Builder 4.5 in the hope of building some mobile applications and am stumbling over the integration of Actionscript with MXML. I need to dynamically build an elaborate game interface by drawing shapes. For some reason, Flash Builder tells me I have an error in the Actionscript here:
I have a text box that receives data from XML. Has activated the service. Everything works fine if i use "taurus" instead myVar in {}. Now I want to change the field and depending on the button is pressed to receive different data. But nothing comes out.
I'm looking to create a flashBuilder document which uses seperate MXML files as "views" which are controlled by states - I believe it's a design pattern of sorts but I'm relatively new to FlashBuilder. I was wondering if anyone knew what design pattern it was and if I can be pointed in the direction of some good references! FYI I'm looking into using FlashBuilder to design Android apps
How do I load XML from a local file into a List component in MXML Flash Builder 4?
I tried using Actionscript to create a loader, but I can't seem to add an event listener to the loader. I've tried to create a local service but I couldn't get that to work either.
I'm making an XML driven AIR app. I plan on having multiple XML files being used - some for content and some for storing settings, state etc.
I imported an .fxp project into a Flash Builder and then observed there are 5 .mxml files in the src/(default package) directory. Silly question -- how to run each of these five files?
Since I've named the project differently than any of the .mxml files, whenever I try to run something it uses the default (empty) .mxml file named after the project. Deleting that empty mxml file didn't help anything. I also tried to clean the project, but nothing changes (although I see the directories refresh with the same contents). There are no html files in the bin-debug directory.
There must be some simple way to run those .mxml files that I'm missing.
So yahoo astra has grate compohent for saving inputed data. They show examples of how to use it. But I had not found one capable to solve my current problem. For example user inputed his name. It is saved, but when he comes again he always needs to input at least first latter of his name. so I wonder - how to make Yahoo astra autocompletemanager component to pop up last inputed into it value on application creation complete?
I am using progressive streaming with VideoDisplay, the HTTP URL provided gets buffered completely even if I have configured it to start playing the video when the buffering reaches 20%, the trace message shows that the playing started(using mozilla /Flashbug+Firebug), but it doesnot show the video till the buffercounter reaches 100% How can I get the video stream to play at the 20% of stream.Code Segment where the check takes place
I have to work with a .fla file. I would like to rewrite this file in AS3. Is it possible? I mean, I would get a .swf file as result of compilation of mxml file in Flash Builder 4 IDE, not Flash CS5 (I don't know CS5, I'm a newbie) . Main target is getting a .swf file by compilation of mxml file, not fla file. Could you explain in detail how this code works? For example what's TXT ? Is it a inputText? Where is this variable defined? Now I 'm linking .fla file ....
I am trying to create a flex app but facing a weird problem I have created a package to keep my mxml file separately and action script file separately. But the problem I am facing is when I am trying to import one of the .mxml component in my actionscript of main file of mxml application then I am not able to do so .can some one help me in importing one mxml file into other mxml file. my flash builder is not recognizing the package in which i have kept my other mxmk file
I have a Debug class I've written, and I'd like to include a static trace() method in there, unfortunately I have no idea how to then access global / top level trace as effectively I've blocked it with the local static scope.[code]
Does MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?
Does anyone know if there is a way to make the new Package Explorer window in Flash Builder emulate Flex Builders 'Flex navigator' window?
Bottom line is I don't always need to peer into SWC's, and I don't like having a 'default package' automatically created for me. Not sure why the interface wasn't made simpler, allowing access to more power and complexity only if necessary. I want to focus on the code, not on how to navigate and use the bells and whistles in the coding environment.
I have an AIR project that I was working on Flash Builder 4.5 which now I'm trying to import to my updated Flash Builder 4.5.1 and it is prompting me to fix some paths before the import is completed. I'm kinda clueless what I should put in those fields.

The project access a web server to retrieve data using JSON.
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:
I am trying to override a Button class, i have a few properties which i wish directly initialise with the mxml description of the component, like :[code]which function is triggered ( in order to override it ) when all properties with mxml description is fully initialised with their values ?
I am trying to migrate a project from Flash Builder 4.0 to Flash Builder 4.5. After Flash Builder prompts me to choose my new SDK, I choose 4.5, Then I get the following error:" error "The required skin state 'disabledWithPrompt' is missing".
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
create a component bc.mxml <?xml version="1.0" encoding="utf-8"?> <s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009"
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.
I was writing some stuff today and i realized that variables inside a class are not constrained to the constructor or method scope. In my opinion this is utter lazynes. Scopes need to be fully enforced to force programmers to comply with correct OOP styles and organization.
to force yourslef to comply with the standards, when reffering to the consturctor always use the 'this' prefix and use 'var' for all temporary variables that should be inside the method scope.
I have 3 mxml components. In Component 1, I let the users fill in some data. In Component 3 I want to use the data, but I can't find a way to make it work.
What is the scope of a class created in Flash? If you create a class on the main timeline, can you use it anywhere in your project? If you use your class in a a movieclip, can you use that class outside of the movie clip?
I'm working on writing a tweening class in as2 that has a callback variable and I can't seem to find a good way to get the scope without specifically passing in a scope variable as well. This tweening class needs to work in classes as well as on the timeline. Here's what my codes looks like right now.params.scope[ params.onComplete ]( params.onCompleteParams );params is an object passed into the class. This works but I don't want to have params.scope in there.
know if the index effect the scope of an object because I am creating a game and for some reason, I get an error like below
TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.objects::Torret/updateObject() at com.objects::EngineApi/loop()
[Code].....
updateObject is the loop for all my objects. I have one centralized loop and in that loop it calls on an array of objects that have been placed on the stage. all of them containing the method updateObject. to update the status of the object. addGameChild() is a encapsulated addChild() , that not only adds the object to the stage, but places it in a array so it's updateObject() method can be called on. it is also used to make it easier for garbage collection.
