I'm trying to create a class that contains an array. However i want to require that the items in the array are themselves of a specific class. Im told there is some sort of tag you can add to do this, but for the life of me i cannot find what it is.What i hope for is something like:
public class myClass{
public var foo:String;
[ArrayType(class="BarClass")]

I'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...
public class HierachyTree extends Tree
public function HierachyTree()
{[code].....
I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:
public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor
{
private var filter:Function[code]..........
The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.
Which code should I give to my button on the main timeline, to control a MC object (instance name "vid"), by forcing it to change to a specific frame?
View 3 RepliesI have been looking to see if it is possible to force an array's elements to only be instances of a specific class. Is it possible in AS? If not could the same result be achived with my own custom object?
View 3 RepliesThrough researching, i've discovered that the problem with using getDefinitionByName is that the compiler believes that my classes aren't being used, unless they're explicitly referenced in the code, and thus isn't compiling them into the swf.I'm having no luck finding an amicable solution to this problem though. So far the only thing that i've found which works, is explicitly mentioning the name of the class, somewhere in my code. This creates huge problems as it forces me to manually edit an additional part of the code. And really, harcoding anything is horribly sloppy.this isn't an acceptable solution as i'm designing a game with potentially hundreds of weapons, and two classes for each one. I need some way to automate this, and force them to compile.
View 6 RepliesI am using Flex to create a small form. All I have at the moment is a List component, that I want to populate with a list of font names.I am getting the fonts using Font.enumerateFonts(true);. This returns an array of flash.text.Font objects.
The Font objects have a fontName property that is a String of that fonts name.My problem is that I can't figure out how to bind the List's dataProvider to the fontName property of each of the Font objects in the Array.Is there a way to do this just with binding? and not creating a new array of Strings by looping through the Font objects?
I'm trying to make a variation on Array for a very specific purpose. When I have the following:
public class TileArray extends Array {
// Intentionally empty - I get the error regardless
}
Why can't I do this?
var tl:TileArray = [1,2,3];
despite the fact that I can do this
var ar:Array = [1,2,3];
The error I receive is this: Implicit coercion of a value with static type Array to a possibly unrelated type
I have what seems a straighfoward situation: I update the source property of an image, when the image is loaded i want to redraw the border skin to fit the new size of the image.

I have a class ErrorMessages which holds all my error messages as static constants. So I could access them like ErrorMessages.PASSWORD_INVALID or ErrorMessage.PASSWORD_TOO_SHORT. I want to know if it is possible to have separate classes that hold subset of these constants and access them like ErrorMessages.PASSWORD.INVALID or ErrorMessages.PASSWORD.TOO_SHORT, etc. This way I can more structured static structure and makes it much easier to use autocomplete. I tried few different ways and couldn't figure out if this was possible..
View 3 RepliesIn flex when I allow user to download a file using :
dwFile = new FileReference();
dwFile.download(downloadURL, dwFileName);
Is there a way to ensure that the downloaded file always ends up with the extension .tar or any other extension for that matter? By default I give it a name like xyz.tar, but as of now the user can tamper with filename, including its extension. Can I prevent him from doing so?

During the application run, I set another custom render to the same column.When I scroll data in the grid (change values for the custom renders) they display new view correctly.I want that they dispaly new view automatically (when I set them): so I think I have to call them and tell tham to refresh rgeir views.
View 1 RepliesI've got a small action-script chart, that's meant to be live updating, and also be able to support more than 10000 points of data. The way it's currently set up it doesn't need to redraw the whole chart if the new line we wish to add doesn't extend that chart's boundaries. Yet it does, the redraw regions show the whole chart as being redrawn as opposed to the single line i need to add. When the chart gets a new piece of data from the javascript it does the following.(some stuff has been stripped for clarity.[code] Is there any better way to do that, that won't redraw the whole screen? Is my coding pattern wrong for this type of update?
View 1 RepliesIs there a simple way to force all the child components of a Flex app to redraw when that app is resized?
For instance, I have a HDividedBox with percentHeight and percentWidth set to 100. On the left hand side of the divided box is a data grid and on the right side is a number of text inputs. The divided box is not added to the view stack until after the user logs on.
If I resize the app before the HDividedBox is added then the box takes up the full size of the app, whatever that may be. However if i resize the app after the box appears then the box retains the same dimensions it does when it was first added.
I would have expected that on the resize of the app then all the children would redraw (the application component itself appears to).
I am creating a component that displays a variable amount of "gauges" (square tiles of content if you will), that is laid out like so:
<HDividedBox id="container">
<VBox id="myComponent">
<HBox id="header">
[code]...
I have a ProgressBar in MANUAL mode responding an URLLoader's progress events that seems to get drawn far less frequently than I would like. If I debug the app, I can see many events firing from the URLLoader yet it seems that the ProgressBar is being re-drawn at some random and slow rate.
Now if this was my own code (URLLoader is a black box), I would pause once in a while to let the UI update, say via loop with a timer. I presume that the URLLoader itself is blocking the main thread from processing drawing code. Adding validateNow() and invalidateDisplayList() does not seem to help much.
private function onLoadProgress(resource: TResource, evt: ProgressEvent): void
{
_progressDialog.prbCurrentItem.setProgress(evt.bytesLoaded, evt.bytesTotal);
_progressDialog.prbCurrentItem.validateNow();
_progressDialog.prbCurrentItem.invalidateDisplayList();
}
Now there are many TResources (just a class that can manage its data) being loaded in sequence, but the URLLoader is so greedy that it does not let the UI get updated more than a few times when loading & processing (parsing into XML objects) 50 or so 10KB files. So just counting which files loaded visually does not work either; I'm lucky to get 2-3 screen updates the entire time.
Loading a 700MB file looks much better, but again the progress bar updates are random and slow.
Additionally, I'd like to know if there is any way to influence or even control the rate at which ProgressEvents are fired by the URLLoader class. I have not been able to find at what rate it normally dispatches progress events either; is it at a fixed percentage per file or every x frames or milliseconds?
As these are local files, would I be better off not using the URLLoader class and instead switching to FileStream?
handling global keyboard events in Flex, is to attach a listener in the application complete event of a Flex application. However, no matter what I try, I have not been able to catch events without clicking on a point on the page, which is hosting my Flex application.
Moreoever, if I use a Flex component in a web application, where there is also html and Javascript, I'd still like to be able to grap global keyboard events, even if the embedded flex component (in flash player) does not have focus. So is there a reliable method for connecting flex applications and components (when they're embedded in a web page) to keyboard events?
I'm trying to make an existing FLEX application section-508-compliant, by getting it to work smoothly with the JAWS screen reader. It kinda sorta works, but one immediate problem is that when you first go to the login screen, your cursor ends up in the userid field, but JAWS doesn't read anything useful (like the label of the field you're in!) until you hit TAB or something. Is there a way to force it to speak immediately on application startup, without making the user tab/backtab just to hear where they are?
For that matter, as cool as it is that it reads interactive controls as the user tabs around, sometimes you just need to make JAWS say something at a particular point in the logic, which might or might not be associated with a conrol... as if you could write AS code like "jaws.speak('');".
Im trying to use an AS3 modification of gskinner's collision detection class, but this being the first custom class i've ever tried to implement, i dont what i'm doing.How do i implement it into my flash? Do I just put it in the same folder as my .fla and .as?Do i have to initiate it in the main class?From what i understand it creates a rectangle, what would i need to turn it into a simple true/false?

I'm using the following array to add children to the stage:
for(var i=0;i<6;i++) {
var aCherry=new cCherry()
aCherry.y=10
aCherry.x=10+100*i
stage.addChild(aCherry)
}
Now I want to modify each cherry based on another array. Something like this:
[Code]...
Clearly stage.getChildByName("aCherry")[i] isn't correct, but coming from JavaScript this makes the most sense to me and should accurately portray what I'm trying to achieve for you guys reading this. So, how would I actually do this? This being getting an array of children added to the stage under a certain name or class (so an array of cCherry would work too, if necessary), then using them in a way similar to the above loop.
I'm making a tile based game in AS3. Now I need to check a collision between the player and each tile (which are created in an array with 300-something instances).

How would you randomize a specific set of values in a array? For example:
Code:
testArray[A , B , C , D , E]
I would like to Flash to only randomize value B C D.
