Flash :: Check If DisplayObject A Is A Descendant Of DisplayObject B?
Oct 26, 2010I would like to be able to quickly check if a given DisplayObject is a descendant (not in the inheritance sense - ie. child, grandchild, great-grandchild, great-great-grandchild, etc.) of another DisplayObject. There doesn't seem to be a native way to do this and I can only think of two ways to achieve it: Create the mother of all nested loops. Seems a bit, I dunno, wrong? Dispatch a bubbling event at the 'child' and check if the potential 'parent' receives it.

ActionScript 3.0 :: Flex - Make Filters Scale Relatively With Parent DisplayObject?
Nov 28, 2009(i'm using flashdevelop / flex sdk)IS there any way filters applied to a DisplayObject (drop shadow, glow, bevel) can scale relatively with the parent (the DisplayObject it is inside)?And what about other properties like .distance for drop shadow?
For example... If I have a 100px rectangle with a 10px glow inside a container object, and I set scaleX/scaleY of the container to .1, I want the glow to inherit the scale change from the parent (1/10th the size) just as the display object does that the filter is applied to.Instead, if you try this, you will see the glow stays at 10px no matter what scale the filter target or the container is transformed by.Pseudocode example (steps to reproduce),
1) create a sprite called _myOuterSprite on stage at scaleX = scaleY = 1
2) create a sprite called _myInnerSprite inside _myOuterSprite at scaleX = scaleY = 1
3) draw 100px rectangle into _myInnerSprite
4) apply 10px glow to _myInnerSprite
5) transform scale of _myOuterSprite to .1
Result:
- child sprite (rectangle) scales to 1/10th the size
- glow stays the same size
How can I make it so that glow scales to 1/10th as well?...without capturing and scaling bitmap data ...without losing interactivity on objects...in a way that would work visually for every filter, not just glow (drop shadow has distance property too, etc)

Flex :: Check If Clicked Element Is Inside Of IVisualElement (parent)?
May 27, 2010I'm trying to check if a clicked element is inside of an IVisualElement in Flex 4. So I want something like "if this element is in this element, then execute function". I'm aware of the 'parent' property but this doesn't seem to work when my element is not a direct child of the element but for example 3 levels deep.

Feb 25, 2009Firstly, I've created a global variable called mc to store a movieclip instance:[code]Later on inside a function, I've created a new instance of my movieclip and added it to the stage.[code]Now, this is working fine most of the time. But at one particular point in my program, after many other things have happened, when trying to remove this movieclip it throws the 'display object must be a child of the caller' error.So, I'm thinking if mc isn't a child of the stage, what is it a child of? Tracing mc.parent returns null - so it seems to be telling me that the parent (which was definitely the stage when it was created) has wandered of somewhere and abandoned my movieclip!I have no idea how this has happened, and as the whole program is several thousand lines long I can't post it here. So, does anyone have any idea what might cause a display object which is added to the stage to become orphaned like this?

Jan 27, 2011The following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

View 2 RepliesFlash :: DisplayObject Snapshot In Flex 3?
Jul 9, 2009i'm creating a visual editor in flex and need to let users export thier projects into Image format. But i have one problem: size of the canvas is fixed and when user add element which is out of these sizes some scroll bars added. And user continue working on the project. but when he want to take snapshot of the canvas he just get the visible part ot the canvas with scrollbars. how to get image of the fullsize canvas?
The only solution i found is to check the positions and sizes of canvas child objects and rezise it to fit them. then take snap and resize back. But it hmmmm... too complicated i think. Is there some "easy methods"?

Flex :: Inheriting Properties From A DisplayObject?
Dec 21, 2009In regards to as3 project: Is there a way to inherit the properties of a given DisplayObject? I am looking for a single method that will grab something like the x, y, width, height, color, etc. Whatever is involved in the common classes between the two display objects.
Edit:
I don't think I was clear enough... Let me give an example of the type of functionality I am looking for.
var sp1:Sprite = new Sprite();
sp1.x = 30;
sp1.y = 30;
sp1.width = 500;
sp1.height = 30;
var tf1:TextField = new TextField();
tf1.inheritTransform(sp1);
So, in this case I know that the method 'inheritTransform()' doesn't exist, but I am wondering if there is something similar. Or maybe I am missing the point of extending a class in some way? I don't see how the two would relate in such a case.
ActionScript 3.0 :: Positioning Parent MC In Order To Center Child MC On Parent's Parent MC
Feb 5, 2010[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]

View 2 RepliesActionscript 3 :: Resize DisplayObject To Fit Panel In Flex Application?
Apr 21, 2010I am trying to attach some of my actionscript class, inherited from Sprite, to my Flex application by attaching it to a UIComponent, then add UIComponent to a panel. However, the size of my Sprite class appears to be larger than the panel. So, I try to resize it using DisplayObject.scale property, but I need to know the size of my container. Since I try to make my code reusable, I figure that I should let my Sprite class handle the resize by getting it via its parent property (let's say, I can resize it by set
this.scaleX = this.parent.Width/this.width or something like this)
However, my Sprite class's parent, which is the UIComponent, has width/height of 0. So, my question is:
1) Is there any better way to resize DisplayObject class to fit its container when attached to Flex object?
2) If you know, why my UIComponent's size remain 0 and my DisplayObject still appears at its full size? Here's my code, using Flash Builder 4:
private var loader:Loader = new Loader();
private function testLoader():void {
var urlRequest:URLRequest = new URLRequest("http://localhost/welcome.png");[code].......

View 2 RepliesFlex :: Flex - Pass Data From Popup To Parent?
Jan 1, 2011I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that?Here's my parent:

View 3 RepliesActionScript 3.0 :: Add A Clip To The Stage As A Child And Remove The Parent And Set The Parent Equal To Null?
Sep 11, 2010if I add a clip to the stage as a child and remove the parent and set the parent equal to null, does the child get collected and removed from memory? What if the child has an image loaded into it as its child?
In my application I'm loading a series of png images as overlays that can be tinted for customizing in this app. When I trace my memory, the basic app idles at 64,000 k. The exact second I load those overlay images it goes up to 205,000k. If I remove those clips and "clear" the stage I should go back down to 64,000 k if everything is removed and collected correctly, right? It's not, it's hanging at 215,000 k. Are my images being cached and that is the reason for the memory staying up? If so, how do I prevent that. Or upon removing the parent of the image how can I un-cache the image.
If a user switches between models and loads several different items then the application actually crashes the Flash environment because of too much memory usage. It also does the same to browsers.
