Flex :: Can (ArrayElementType) Metadata Tag Be Used On A Function Parameter
Jun 23, 2010
What language construction can be used to make a compile time checking of Array elements type when the Array is a function parameter?[code]Here we've marked the returned Array as one containing elements of type string.Is there a way to mark the parameter variable as an Array containing elements of certain type?I'm specially interested in the Array collection. I'm aware of the vector collection but I have reasons not to use it in my case.

Is there an easy way to validate that the type passed to the Constructor is one of the Static Constants of the Class, without having to check it against each value?

In as3, I am adding event listener and then attaching the anonymous function to it:[code]Now this whole piece of code is looped n times. Now, I have n myBoxes and whenever I roll my mouse over the box, it should alert the name. But, what I see is that the last value of count is used by each box. How can I pass parameter or value to the anonymous function? ( as roll over , I believe, expects only one variable)

I'm using FlashBuilder 4 beta2. My base class has a function foo():
protected function foo(s:String, z:String=null): void{}
Literally "foo" so that there's no chance I'm stepping on a built-in method. I am getting an
"Incompatible override" error when attempting to override the method in a subclass:
override protected function foo(s:String, z:String=null): void{}
Does the optional parameter do something "behind the scenes" that makes it illegal to override the method?

I want to use OnMetaData to get when a video.flv is done playing. I try different ways to do this even building a class but to no avail. For some reason I can't get inside the metaDataHandler function and trace a string (or bring metadata out) to let me know I'm inside.
import com.lynda.xml.*;
import com.lynda.php.*;

Forgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
I have tried things like
Code:
addToXML.addEventListener(Event.COMPLETE, loadList);
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."

I'm having some trouble passing parameters with a function that is itself being passed as a parameter.In my application code I'm instancing that class five times:they are buttons in a menu.In that class, I've got an onRelease handler that does a number of things when a button is released, one of which is to invoke a function that is defined in the application level of the code.My problem is that I don't know how to send the function parameters.In my StandardButton class I have:
class StandardButton extends MovieClip
{
/* define properties */[code]..........
The function is successfully being "sent" to the StandardButton class, but without any parameters.How can I send parameters to the class instance with the way I've got this architected.

overriding clone() while creating custom events?I read in the Flex cookbook that we need just in case we want to redispatch this event. Does this exactly means that when we want event to be bubbled up the display hierarchy , at that time our custom cloned event should be dispatched and not the Event object.
second - whats the need of metadata tag -
[Event(name="modelEvent", type="com.abc.data.model.ModelEvent")]
public class LoginModel extends EventDispatcher
I understand we need to extend EventDispatcher in case we want to dispatch evnet from class.. but In what cases i would need to specify the MetaData TAg
Third is.. If i write -- "dynamic customEventClass extends Event".. Is there any use of Dynamic i can make?

I know that it is possible to add swf metadata to the compile command as a command option, but I can't find any documentation on how to access these metadata within the actionscript during runtime. We're trying to add a version number to the swf during compile time and then somewhere in our app we would retrieve it during runtime, here is the command example to add the description metadata.
mxmlc -description "version 1.2.3"
I know the swf metadata is used by search engines and other utilities to gather information about the SWF file, but surely you should be able to retrieve them in the actionscript during runtime?

I'm trying to embed a font in Flex and the code I'm using looks the same as the example, but throws an error. This is the code I've written:
[Embed(source="data/posca_mad_thrasherz/posca_mad_thrasherz.ttf",
fontName = "fontGraffiti",
fontWeight = "bold",
mimeType="application/x-font")];
private var funFont:Class;
But I get the error, "Metadata requires an associated definition." I can't seem to get rid of it.

I have a situation where a simple query against a table is returning incorrect values in Flex, but not in other GUI front-ends to SQLite.
select title from ttl where ttl.ttl = 140 // ttl is also the column name of the PK column
is returning the title that belongs to the row whose PK = 1400.
ttl.ttl is defined as int datatype.
Again, the problem manifests itself only in Flex, not in other GUI front-ends to SQLite, which are returning the correct title value.

I saw that you can embed meta-data into images very much like you can in mp3s, here.
Can someone point me to a tutorial of how to embed and read this sort of information w/ photoshop and flex together? I really wouldn't know where to start... Tried googling but I'm not sure I have the right keywords down.

I have an actionscript, which makes a dynamic image wall. It gets parameters from FlashVar and changes the width and height dynamically.
When I use
[SWF(width="584",height="290")]
It's fully centered, but when I remove it, it's appear ~+50px from left. How can I set dynamically the SWF metadata or what I need to set for the correct view?
Top of the picture with SWF tag and the bottom is without SWF tag.

I am just just curious as to whether the [Bindable] metadata tag in ActionScript 3 can only be used within the Flex framework, or can it be used in "regular" ActionScript projects where Flex isn't used?

I am working over a program that needs to extract meta data from music files in different formats. It was easy for MP3 format, but there is nothing for other formats.I made a research, there is a lot of software for extracting meta data - but no source code or algorithm. There are open source projects, they use their own libraries, but I was not able to find something for Flex (Action Script)

we have following class
[Code]...
If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)

I'm designing a game that uses this function;
function moveBars(Bl:Number,Gr:Number,Or:Number,Ye:Number)
{
blueBar_mc.scaleX += Bl;
greenBar_mc.scaleX += Gr;
orangeBar_mc.scaleX += Or;
yellowBar_mc.scaleX += Ye;
}
When moveBars is called, the length of the 4 colored bars change to indicate how the player is doing in different areas of the game, like so; moveBars(.1,-.2,.3,-.1)
My problem; I need to store the moveBars parameter arguments in XML like so;
<myArgs> .1,-.2,.3,-.1 </myArgs>
But I can't find the way to get those 4 numbers into the moveBars parameters from the XML doc. Is there a way to do this?

Essentially, I have a function with three parameters, that works fine when I type in the parameter values. The function is tweens(MCname, targX, targY) and it runs properly when I use tweens(btn1, 150, 200) for instance. I need the function to move 6 different movie clips, one at a time, and I am using a variable (Counter) and an if statement to tell the function to run again after one of my tween classes finishes. The code all works, and it will run six times with the same clip if I just type in one of the movie clip's instance names as the MCname parameter.
BUT, if I try to use a variable (BTNname) to serve as the MCname parameter, it will not work, making it so I cannot apply the function to my 6 different movie clips. I put a trace on the MCname parameter, and it returns the correct value (btn1, btn2, btn3, etc) but it is not moving the corresponding movieclips. I've tried a number of different methods, but nothing will work.[code]...

I'm trying to program a race timer with OOP, and I've been adding more and morefunctionality to its class. Everything had been running well, until I had the idea to put a countdown() function, to make a cool countdown effect. Things got worse when I wanted to make the countdown function to call another function when the countdown effect has finished.The code runs well when I first pass a function parameter from the Main class to the Timer'scountdown() function. The problem begins when I want that function to be past again on other private function of the same class, because this time, the function becomes nullOn the Main class constructor, I 've written the following line:

timer.countdown(5, false, myFunc);

I am sending a name of a function via parameters to another function. This allows more usage of a single function. However, the button commands work every-so-often. The message appears everytime with no problem.
Code:
_root.msgReveal("This is just a random message. Click the ok button to close.", false, true, false, false, _level0.msgHide(), false);
Code:
function msgReveal(msgString:String, btn1B:Boolean, btn2B:Boolean, btn3B:Boolean, command1:Function, command2:Function, command3:Function) {
msg.messageBox._visible = true;
msg.messageBox.textF.htmlText = msgString;
