In UI component life cycle, I heard validation and invalidation events. Please explain me about these events in short. What does updateDisplayList() method do in that life cycle. Please explain me in short if possible.
View 2 RepliesI am confused with how component life cycle goes when component build in MXML. and if MXML calls methods automatically then how to call any method in life cycle explicitly.
View 1 RepliesDriven on by curiosity, I'm trying to understand the Life Cycle used by Flex Application. I've done a little research on this argument; the two key concepts used into the FlashPlayer are:
SWF Frame: it's the logical unit that contains graphical code and as code Flash Player Frame: it's the time interval used by Flash runtime to update the screen and defined by frameRate property
If so, could you explain me the relationship bewteen these two concepts? In particular, are they paired togheter or not? The main rule is: the Flash Player streams in a swf; until a full SWF Frame is read, the Flash Player cannot render it.
I'll try to explain what I need to understand. For the sake of simplicity, suppose you have a two frame application: SWF FR 1 and SWF FR 2.
In general (for example in CS4) a frame is considered as a logical unit (delimited by ShowFrame tag) where you can attach as3 code. This as a simplified version of a swf file, i think:
Header // frameRate is defined here
Symbols, classes etc... // this is FR1
=== ShowFrame ===
Symbols, classes etc... // this is FR2
If you have two frame, FR1 and FR2, Flash starts executing FR1 and goes to the next one (FR2). If you don't stop the excution, the Player executes and renderes code contained into FR1 and FR2 through an infinite loop. On the contrary, when you stop the execution, for example in FR2, the flash player loops executing code contained in FR2.

Nice to be back to this forum again. I need to know if instances of the movieclip, that is "classically tweened" are reused between keyframes, or are they recreated (reinstantiated). Thus may I rely on the fact, that only the properties of one single instance change during the classic tween, or are new instances created on entering keyframes?
My little experiments on that show that the bad variant is happening (instances are recreated), but maybe I misunderstand or misuse something? here is the link to the file which made me doubt (CS4). In the last frame of the animation all previously saved references to the instance are saved abnd compared in pairs. Not all of them are equal and sometimes event some are null.[URL]...
For some reason I can't seem to match a parentheses in Flex using Regex to save my life. What's wrong with this?
var commandTxt:String = "switchview(adf)";
var switchViewArray:Array = commandTxt.match(new RegExp("switchview(", "i"));
I've tried dozens of things, but I can't seem to get a match the parentheses. What's the catch here?
I'm trying to cycle between 2 different tween actions in Flex. Here is what I'm trying so far: In declarations:

The problem is that once I start the animation (by clicking a button), I get a timeout error saying the script has been running for longer than 15 seconds, with no tweening ever occurring. The animation works if I were simply animating it once.
I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

I have a little math problem with a game I'm making, and I can't for the life of me figure out the formula needed to accomplish something..Say, there's a sniping game, and a BIG image that must scroll from left to right according to the mouse movement.
Something like this:[URL]... In that example, the scene is 550 pixels wide, and the image is 1100, exactly two times the scene, so the formula is kinda easy..
[Code]...
the center of the image would be at x 1500, way over to the right of the scene, outside it, but it would fit inside the screen, like this (the blue square represents the real size of the scene):[URL]..Then when the mouse is at the far right side, that is 550 x, the image center should be at -950 x, like this:[URL]...
I am looking to add some life to this graphic in flash: [URL] My goal is to have the "Hey Jude" element drop into frame and be suspended by the two strings that are attached to it. i.e. similar in fashion like a swingset I have looked all over the web but have yet to find any leads/tutorials on the matter. I would also like this element to be physics based so that the motion is random and when the element is moused over it responds to the action.

View 3 RepliesSo I have a movieclip which has a bunch of children in it. They are each a bodypart of the movieclip(which represents a guy). He has a hand child which he has 2 copies of one for left and right. They both come from the same hand library item. Now here is the challenge. There is a lot of pre-existing animation data in this format so I need to work within these confines.
What I want to do is be able to tell on a given frame which hand is the left and which is the right. It doesnt matter which is called which even, I just need to give each a unique identifier. The problem is it appears if i set a variable in frame one on the hand object, in frame 2 a new hand is made and that variable is lost. So I can't seem to track it by just putting a variable on each hand with a name like hand1, and hand2.
Is there any way to track something like this across many frames? The overall goal is to output the x,y and rotation for each body part for each frame and be able to tell what body part it is (hand1 vs hand2)
I would like a bit of script that I could attach to some buttons so it looks like they are wobbling slighty on roll over.The atached jpeg shows the basic design of them - opaque with shadows.I would like the movement to be random, i can programme it already to move up and down or whatever, but not so its a differnt movement every time.

In the following code, the call to myChild.bar() results in an exception because myChild is null. myParent is a valid object. What I don't understand is why myChild has not been created yet.I have read the following document related to object creation sequence, but I am unsure how "new" is related:docs

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?

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?
