is it possible to retrieve all children of a certain type from a parent in actionscript 3? i only see getChildAt,getChildByName, is there a getchild of a certain type like get all childs of object type:Food?

View 3 RepliesIs there an easy way to make a parent container (eg Group) resize when it's children resize?
Below is a little example app. When I put the 200x200 'food' in the 'stomach' the stomach & it's containing 100x100 'body' should resize to contain the food.

I have code like the following:
<s:VGroup gap="10" id="group" height="100%">
<s:Label text="This is page 2" />
<s:Button content="Resize Canvas" click="resize(event);"/>
<mx:Canvas id="photoCanvas" color="#567898" backgroundColor="#125567">
</mx:Canvas>
</s:VGroup>
I don't understand why the following does not work:
Pushing the Button resizes the photoCanvas's height (gets taller or smaller). Since the photoCanvas control is a child element of the VGroup shouldn't the container update itself to the new height? The Vgroup has ALWAYS the same height, no matter what the (total) height of the children is! I would like the VGroup to adjust itself and get a height value equal to the sum of its children heights. Is this not possible??
I'm currently working on a custom component which extends Canvas (let's call it SuperCanvas) ; it's basically a container that let you zoom & pan its contents. It would be too long to explain why, but I can't use scrollRect, so I was forced to declare a Canvas object (called innerCanvas)... inside my SuperCanvas (I know, not very nice =/) I would like to know if there's a proper way to "redirect" the creation of my component's children in this canvas.

How to avoid children inheriting parent's colortransform in flash?
View 2 RepliesI add to a movieclip various Textfields using addchild.How could I get all Textfields in the movieclip to remove (or edit) them?
View 3 RepliesI have a canvas onto which I draw shapes like rectangle etc. When I move the shape using my custom mouse down/mouse move handler, the shape can go outside the parent bounds.
I am checking if the child is outside the parent's bound to snap it back:
var bounds:Rectangle = this.getBounds(this.parent);
var p:Point;
if (bounds.x <0) {
[Code]...
The snapInside method gets called when I go outside the left or top boundary. But when the child is dragged outside the right or bottom boundary, I find Flex/Flash runtime automatically expands the parent's height and width. So say the parent size was initially 800x600, if child Y bounds exceed 800 by say 20 pixel, I find the this.parent.height automatically resized by flex to 820!!
How do I prevent the parent from resizing when child goes outside the original bounds of the parent ?
Red: Shape inside parent movieclip,
Yellow: Children inside parent movieclip
I'd like to animate the yellow dots, but make sure that they never gets out of the red shape's boundary.
i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).
View 5 RepliesI have placed 3 movieclips named mcParent, mcChild1, mcChild2 and 1 textbox in flash. child are childrens of parent movie clip. child1 and child2 both are of sizes 300 whereas parent movieclip is 600px, textbox is placed inside child2 movie clip .
I have made the flash to auto resize according to the screen area. Everything works well, but after resize it resizes parent and all childrens and textbox which is correct. The problem is with the correct placement of textbox on mcChild2. I have seen that after resize, mcParent width and scalex both changes but the child clips doesn't changed its sizes even they are stretched but there sizes are not updated due to which I am unable to get the exact location of where to place the textbox.
On the stage I have a movieclip (Container, originally 200px width) and inside it with a progressbar movieclip (originally 700px width), scaled with Free Transform Tool to fit the parent container. The width of the container changes run-time while resizing the scene.
In ActionScript I have a function which should set the progress bar width according to a calculated percentage value:
private function updateProgress(event:TimerEvent):void
{
var barWidth:int = _container.width;
var progress:Number = _stream.time / _stream.duration * barWidth;
_progressBar.width = progress;
}
My problem is that the progressBar even at full time (100%) is only at 1/4 of the parent container. I assume that it comes from the symbols original size.
Can I correct this programatically, or I must redesign it with the "designer"?
I have a little trouble in managing the children my container. The fact is that it has a lot of children and their y coordinates are very random.
Is there anyway i can order them by y coordinates that the lower will be in the front and the higher with be in the back?
is it something that that I can do with 2 "for"?
Well I'm starting to really enjoy AS3, my next question then is this: In AS2 I'd often remove all movieclips with something like this:
PHP Code:
for(var i: String in container) {
container[i].removeMovieClip();
}
Is there something similar in AS3 that I can do without resorting to maintaining an array of references to each child of my container?

I am having trouble determining where to add my removeChild() statement to clear multiple movieClips from a container mc. I know I need to determine if the container movieclip contains anything. I don't know how or what I should put and where to put it. If I can determine if my container mc has movies in it, I am assuming I can just declare it again (i.e
PHP Code:
panel= new MovieClip();
)to clear it. Am I correct?

I'm using as container for my LinkButtons. I would like to know
1) How can I remove the space between the items in my Tile container.
2) How can I set dynamic width for my items (at the moment they all have the same width regardless the width of the included component)
3) How can I avoid to display scrollbars if the items are not included in the container
If I have a container, and I set clipContent to true, how do I get the total height of the children inside it? Is there a method for doing this without itinerating through every child and summing the heights?
View 1 RepliesAt one point in my script I'd like to check a MC for the number of children and limit this number to 3. For that I use this script:
Code:
if (container.numChildren > 3){
for (i = container.numChildren; i > 3; i--){
container.removeChild(container.getChildAt(i-1));
popError('Horizontal nur 3 Elemente!');
}
}
This somehow works fine if there are 4 or 5 children in the MovieClip, but as soon as there are 6 or more, it throws an Argument Error #2025 and does not remove anything. BTW it does not make difference if I use container.removeChildAt(i-1);
i'm getting the #1010 error... code below:
Code:
var curProject:int = 0;
var curExample:int = 0;
var container:MovieClip = new MovieClip();
im.addChild(container);

I can't come up with a function that will collect the names of the children in a object container and put them in a array.
View 4 RepliesI'm using an accordion container that has it's creation policy set to auto. One of the accordion's children is a spark border container that has a data grid within it. Currently, I'm using the data grid's creationComplete property to call a function; similarly, I'm using the dragComplete property to call another function.
How can I add listeners for events (creationComplete & dragComplete) via actionscript? The obvious problem is that the accordion does not create all its children on creation (nor do I want it to), so I can't simply use something like: datagrid.addEventListener(...)
I have a VBox inside a Canvas. The 'red bars' are custom components based on 'Canvas'. All red bars are of equal height. I have 20 red bars inside the VBox. The scrollbars visible in the screenshot are the Canvas's scrollbars. The scrollbars of the VBox are disabled using verticalScrollPolicy = off.
Without scrolling, only 16 red bars (and a part of the 17th bar) are visible. However, when I scroll down the Canvas I expect to see the remaining red bars - but the bars that are not visible when the application starts don't get 'drawn'. What am I doing wrong? I want the user to be able to see the 17th - 20th bars when the Canvas is scrolled down.
How do I remove all children from a display object container? I want to make sure that when I re-enter a particular frame that there are no imageLoaders loaded into my photoGallery.
View 2 RepliesWhat's the best way to scale a container mc but not scale the children inside it? Basically I have a box mc with a background colour, with a logo added using addChild, if the user changes the browser size the box scales to the height of the window but it's also scaling the logo, I just want to change the height of the container box really.
View 4 RepliesI'm trying to avoid the scroll bar appearance on an UIComponent. Is there any way to obtain the computed width/height that my container component should have to have all children visible? I don't want to compute it myself. I would like to know if there is any variable computed by the component when it decides if it should draw the scroll bar or not.

Flex's new States re-parents visual items that are marked with includeIn/excludeFrom. If I have a Group (MainGroup) with 5 children/elements that are state controlled, is there still a way to get a reference to MainGroup's children? mainGroup.numChildren and mainGroup.numElements don't work since the children are re-parented. At best, they show 1.
