I'm coding up some delicious business logic and I've come to a situation like this: There are a bunch of rules ( ruleA , ruleB , etc...) which all follow a standard pattern. I've created a Rule interface, and implemented it in RuleA , RuleB , and so on. So now I just need a way to load them. Right now I'm using a map: var rules:Object = { ruleA: new RuleA(), ruleB: new RuleB(), ... }; Then calling it like this: function doStuff(whichRule:String, someData:Object):* { return rules[whichRule].applyTo(someData); } Now, the rules follow a standard naming scheme, and they are all part of one package

I am trying to create a Custom Flex Component using the Flex Component framework: http://www.adobe.com/livedocs/flex/3/html/help.html?content=ascomponents_advanced_3.html . All good components allow you to define their dimensions using percentage values using: MXML: TextInput width="100%" or Actionscript at runtime: textinp.percentWidth = 100; My question is how do you implement percentage width/height in the measure() method of your custom component? More specifically, these percentages are converted to pixels values at some stage, how is this done? The way Flex layouting works is by letting

I'm looking for a way to do something similar to a c/c++ #define in adobe flex. I'd like to have lots of different paths a project build can take depending on wither or not something was defined. Does such a thing exist in flex? I know there is ways to set global variables but that wont really suit my purpose. being able to have structures with numerous #ifndefined and such is really what i'm in need of. thanks! Actually MXMLC (the compiler in the Flex SDK) does support some limited preprocessor features. You can use them to pass in constant values, or to simulate #ifdef / #ifndef type

I want to sort an Arraycollection by fieldName as ascending. Here's my code and I want to know whether it's right. Do you have any suggestions? public static function arrayCollectionSort(ar:ArrayCollection, fieldName:String, isNumeric:Boolean):void {var dataSortField:SortField = new SortField(); dataSortField.name = fieldName; dataSortField.numeric = isNumeric; var numericDataSort:Sort = new Sort(); numericDataSort.fields = [dataSortField]; arrCol.sort = numericDataSort; arrCol.refresh();} Sagar Rawal The code you have is correct, except for a type. arrCol should be ar . The code looks almost

I have a List and the item renderer displays an image. Whenever you scroll the list, and the item renderer refreshes, it redownloads the image. Causing there to always be a delay. Is there some way of caching it so it doesn't have to redownload every time causing a delay in showing the image every time you scroll the list? Thanks! Here is nice solution with source code http://demo.quietlyscheming.com/superImage/app.html You'll have to implement your own caching. I would store all the images that have been previously downloaded and load them if the user goes back to them. I remember doing this

Any clues how this can be achieved? It needs to work on all resolutions .. is there any parent/stage object available to find out the resolution of the system? public function init():void { nativeWindow.x = ( Screen.mainScreen.bounds.width - 300 ) nativeWindow.y = ( Screen.mainScreen.bounds.height - 65 ) } This is a 300x65 window positioned in the bottom right. You are looking for Screen . Screen.mainScreen.visibleBounds takes the taskbar into account Another option is to create a transparent window, then maximise it, then position your window inside the transparent one, using standard bottom
