Actionscript 3 :: How To Fast Reorder Child Elements In Flex 4
Nov 30, 2010
I have a control which contains many child elements (about 1000), and I need to sort them.Now I doing that like this:
_elements.sortOn(...);
for (var i: int = 0; i < _elements.length; i++) {
setItemIndex(_childItems[_elements[i].id], i);
}
_childElement - object that contains UI-child elements, which i need to sort (key of the dictionary is an identifier from data-object
_elements - array contains data-objects
But this is too slow! How to reorder the childs by my criteria as fast as possible?

I'm working on a simple task/calendar tool where tasks can be added dynamically to a canvas. Here is the main application as defined in Main.mxml, which is essentially just a Canvas and a button for adding a task:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Canvas id="MainCanvas" borderStyle="solid" width="300" height="300">
[Code].....
The problem is that when I add a Task instance to the Canvas, the children (the button and label) don't appear. I tried setting creationPolicy="all" on both the Canvas and the BorderContainer, but it still didn't work. I've read a bunch of posts about people having issues accessing members of their class before the class is fully loading, but all I want to do is SEE that Label and Button show up inside the BorderContainer.

I have a Hdividedbox, which has three child elements.
I want to set the initial ration of sizes, such that the first one is 30%, the second is 40% & the third is 30% of the Hdividedbox's width.

I am unable to find if the spark DataGrid supports moving / reordering the columns. If not what could be the best solution? Maybe using the mx version?
I want the user to be able to drag the columns and arrange them.

I have a Flex List which is databound to a Array. My problem is that when I reorder the List using the built in dragMoveEnabled, the values are reset to the original values.I assume I need to somehow do a two-way databinding but I am not sure how.
<mx:List width="100%" top="20" id="uiItemList" dragMoveEnabled="true" bottom="0"
dragEnabled="true" dropEnabled="true"
dataProvider="{listArray}" >
<mx:itemRenderer>

I have a movieclip, with the instance name SizingBox, on the main timeline. Within that mc, I have a Slider component, with the instance name Sizer. I want to declare an action listener on the main timeline which will listen to changes for Sizer and do something based on the current value of the slider.In AS2 this was really easy, but I cannot seem to figure it out for AS3.
Code:
var X = SizingBox.Sizer.value;
this code gives an error.

I am trying to develeop a Graph Structure with drag and drop features in Flex. I have to connect various components/children on the canvas. Once i drag n drop the components on the canvas, i am using SystemManager event handlers to draw connectors between the components. But, as i click on one component and drag the mouse, the line is drawn on the canvas as long as my mouse stays only on the canvas. If the mouse moves over a component/child(that has been dragged and dropped onto the canvas), the line is drawn to the origin of the canvas from the first clicked component. How shud i recognize the component when i move my mouse over the component? I want the line to be drawn connecting the components once my mouseup event is called.

Ok every time I think I understand the DisplayObject model i find something else that seems like it should work but fails. Am I correct that if I create a sprite then create another sprite and add it as a child the original parent sprite will show a height of 0... In my case i have three classes that all extend Sprite and each one is creating the next with the "youngest child" being a class that adds an image to its "stage". I can see the image height fine but its holder does not nor does its holders parent... im having a real moment here as I debate if im just stupid and missing the obvious way to do this or if I really have to add a bunch of getters and setters to see the height that includes children.Maybe I am thinking of this too much like a CSS block element but it just seems like it should work this way...for example
parent "holder" <- child "slide" <- child "image"
holder.height == 0
slide.height == 0

I have the following XML structure:
[Code]...
This will parse child elements of the <text-block> but will not work with <ul> as it has its own child elements <li>. I guess this could be accomplished with yet another loop but I wanted to check to see if there was another simpler way.

I'm building a portfolio site and I've renamed the secenes and reordered them but when I test the movie it defaults to what was originally scene 1. I'm working in AS2. If the mods will allow the web site is [URL]. There is an intro page which was scene 6 which is now renamed "intro" and draggd to the top of the pile but it doesnt show when I preview or upload.

I am trying to write a function that is passed an array and will then reorder it randomly and return the array. My problem is that as the position is generated randomly I dont know how long the loop must run for, this function doesn't work but it should give you an idea of what I'm trying to do:

function randomise(the_ar:Array):Array {

I am loading a master XML file and then trying to break it down into sections
Here's my XML file:
Code:
<listarray>
<items>
<entry type="ecard" num="2">
[Code]....
So I was able to create a new array that contains only entries with the attribute "ecard" in them, but now I want to re-order that array into numerical order based on the attribute "num" so that it lists as Ecard 1, Ecard 2, Ecard 3 in the XML. How would I go about re-ordering the new array I've created?

Problem is that my rewind and fast forward buttons do not work properly in the sense that they start to mess up when you fast forward or rewind past the current scene. It seems to just skip through the whole movie and totally mess up the animation.the code for the controls is on a single layer and reads as the following:
stop();
play_btn.onRelease = function (){
play();

I have an Movie Clip in Flash that have subobject of button type which has subobject of input text and movie clips. Right after creation core Moveclip all subobject are set to null, when I expect them to be valid objects.
[Code]...
MC_Core_design was created in Flash and exported to Actionscript. I've done this for button_1 class aswell. The code was written using Flex. When I comment out both lines that result in error I get correct view of the core Movie clip with all subobject. How can I set subobject properties right after object creation?

I have the following situation: have a screen with 4 charts, each being populated with 59 array collections. Each array collection has 2000+ data points. This construct needs to be filtered(by time), but the problem I'm encountering is the fact that it takes a long time for the filtering to finish (which is to expected given the amount of data points that need to filtered).
Filtering one chart at a time is not option, so I wanted to ask you what do you think would be the best approach? (should I use vector instead?). To generalize this question what would be the best way to filter large collections in flex/as3?

I am making a horizontal list that I want to be able to drag each item around to reorder the list. When one clip is dragged over another I want the one under it to move left or right to fill in the empty space left by the clip being dragged. I cannot seem to figure out how to tell which movieclip is touching or "under" the movieclip currently being dragged around. It seems that the hitTestObject method need explicity instance names to work. In summary, I want to know the instance name of any display object that the dragging moveclip touches.

I am having difficulty getting a reference to elements added after compile-time using the 'id' property. I have seen a few forum topics suggesting that this isn't possible, and that getting a reference to elements added this way is trickier, but never just exactly what that trick is. This code throws a fun little: Error: uncaught exception: Error calling method on NPObject! [plugin exception: "ReferenceError: Error #1069: Property canvas_tentpoles_0 not found on SGraph and there is no default value."].
