I have an ArrayCollection with values predefined. I want to assign a new value to items in the arrayCollection but can not figure out how. Basically I want to do something like this:acGuages.itemUpdated(0).thevalue = 90; (Changing the value from 25 to 90)
private var arrayGuages:Array=[
{thevalue:"25",height:"115"},
{thevalue:"45",height:"115"},
[code].....
is it somehow possible to get item's depth in ArrayCollection?
View 3 RepliesI use a spark List with a custom item renderer and an ArrayCollection for dataProvider.
The ItemRenderer looks something like
<mx:TextInput id="txtValue1" text="{data.myFirstValue}"/>
<mx:TextInput id="txtValue2" text="{data.mySecondValue}"/>
However, even though I change the text in txtValue1 or txtValue2, those are not actually changed in the object inside the ArrayCollection.
myFirstValue and mySecondValue are decorated with the [Bindable] tag.
My understanding is that if the text property is set to be bound a certain property, the changes should be automatically applied.
So the HACK (or so I think) that I use is to listen to the focusOut event of each textbox, and access the parent data provider and set the the values manually.
I have some XML structures like this:
var struct:XML = <mh>
<mi id="1" stuff="whatever"/>
[Code]....
I wonder if items can be accessed in a similar way, like this:
var stuff:Object = cmenu['id == 2'].stuff;
I have an ArrayCollection where I want to be able to bubble items up or down by one position. What is the best way to do this?
View 2 Repliesi got an Arraycollection which holds other arrays in it.i want to display the data inside with an item render but cant manage to do this
here is example code to explain my question
<s:DataGroup dataProvider="{news}"
itemRenderer="components.displaynews">
and this is the item render
<s:Label text="{data.??/}"/>
now what i dont understand is what comes after data? in the array collection the data goes like this : myArrayCollection->[0]->firstname
so when im binding data to item render,how do i represent the [x] to get to the specific name that i want? this obviusly wont work
<s:Label text="{data.[0].name/}"/>
and one more thing is what is the lightest way to display data in a listgroup with simple item render (image and text)
private function convertFBEventData2TreeData(eventData:Object):Object
{
var children:ArrayCollection = new ArrayCollection();[code].....
i dont know what to add after data, i tried many things but nothing work :
Is there a way to reverse the order of the items in a comboBox? I'd like to use index numbers to refer to items in the arrayCollection below. I want the newest content to appear first in the comboBox. But, if I add something above the first item then all of the index numbers will be off by one. If I could add a new item to the end of the arrayCollection, but have it appear first in the comboBox drop down that would solve a lot of problems.

I have used states in my application.The thing is I have made the first item in my list to be selected. so I gave like this,
if(itemIndex == 0)
this.currentState="selected";
this works fine.The problem is when other item is selected the first item does not change its state,it remains in the selected state until its clicked.My code looks like this,
<s:BorderContainer id="outerCont" width="275" height="100" borderVisible="false"
backgroundColor.normal="#3D3C3C" backgroundAlpha.selected="0.1"
backgroundColor.selected="{data.color}">
My states are like this,
<s:states>
<s:State name="normal" />
<s:State name="hovered" />[code]........

I trying to read a value from an ArrayCollection, I use getItemAt and get an object:
masterData.getItemAt(0,0)

</d>
Now How can I get the value in "< i >" tag?
I have a component where I expose the property 'questions' with the following code:
private var _questions:ArrayCollection;
private var questionsChanged:Boolean;
[Bindable("questionsChanged")]
[Code]....
In this component, I use commitProperties() to implement my logic.
I use Cairngorm and the 'questions' is in the model and hence it's defined as a source for data binding.
When the 'questions' ArrayCollection's size changes elsewhere in the application, it is not invoking the setter method in the component that is destination for the data binding.
Is there any way to move an item from one position in an ArrayCollection to another without removing and then adding it? There's no setItemIndex function in ArrayCollection, but there is a CollectionEventKind.MOVE that can be dispatched in a CollectionEvent. Does anyone know how to get ArrayCollection or any of it's cousins to dispatch that event?
I'm using the item as a dataprovider to a listy thing that implements effects, and I want the list to reuse the same ItemRenderer instead of creating a new one.
I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >

I am currently using the latest verion of Adobe Flash Builder to create a Mobile Application. For the application one feature is to allow the users to bookmark content an this is done by storing the id of the object to be Bookmarked into an SQLite db on the device. This part has been done successfully and they are stored fine.
Now what I want to do is to pull back the bookmarked id's from the database and pass them to a WebService call which needs to be made to an External Database. When I retrieve the Bookmark id's from the local database they are contained within object, I now need to find a way to take the id's from the database objects in the ArrayCollection and store them in a new array that will be passed to the WebService, as the webservice is expecting an Array of Int's and not Objects. Below is the code I created to see if the object items are within the array list of objects:
private function loop():void
{
var index:int;

If I have several items that move across the screen but the user can click any of them at any time, how do I record the current position of any of the items item in order to use that data to change the position of the item after the user clicks?
This is what I am doing: I have 11 images that slide accross the screen. The user can click any of them at any time. When he clicks one I am scaling the image so it looks like it is comming forward (z axis) and then the rest of the images are scaled down so it looks like they are going back on z axis. So what I am trying to do is get the current position of the image when the user clicks the image so that I can use that to correctly estimate the scaling and moving of the image to make it look like it scales from the center and not from the top left corner. So if have a variable that gets the current position of the image being clicked I'm thinking I can change its position using something like: x = currentposition + -45;
I have this code to try to acess the values of the array in the arraycollection but it does not work it actually creates a value to the end of the arraycollection. can anyone tell me what im doing wrong i basically whant to modifys the individual arrays in the arraycollection and add Login_user.

I'm creating a mobile app in which I need to show a calendar with months at the top. The months are part of a component that extends from SkinnableDataContainer (and has some custom scrolling/behaviour - which is why I did'nt use a spark list). I need the months to be shown as a 'trapezium' shaped tab and so I'm using a png image as a mask in the item renderer for the component.
When the mask is not applied, it all works well - the months render, the list/data container selection works when I click on a month and so on.When the mask is applied, it renders well, scrolling and everything else seems to work well - but when I click on a month, nothing happens visually. And from the trace statements in my code, it appears list item selection is not changing. Looks like mouse clicks are not working.
Code:
public class TopCalendarMonthRenderer extends LabelItemRenderer {
[Embed(source="/assets/trapezium_alpha.png")]
private static var TrapeziumMask:Class;
private static var trapeziumMaskInstance:BitmapAsset;

View 3 RepliesI have a advanced datagrid and populating some data by using arraycollection. And i am filtering the arraycollection, the arraycollection index got changed.
Arraycollection:- [0] - name: abc
[1] - name: hello
[2] - name: hello1
[3] - name:hai
after filtering the arraycollection as 'hell' , the array collection is displaying like the below:
Arraycollection:-
[0] - name: hello1
[1] - name: hello
Can i know the reason why the index got changed after filter it?
* no server side code for filtering. it is only flex side filtering.
i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

the applicable differences between an ArrayCollection and a Vector in flex? I'm unsure if I should be using one over the other. I saw that Vector is type safe and that makes me feel better, but are there disadvantages?
public var ac:ArrayCollection = new ArrayCollection();
versus
public var vec:Vector.<String> = new Vector.<String>();
ive got most of my playlist set. it consists of dynamic text boxes which read id3 songNames. ive got the playlist items to be inactive when the corresponding song is playing, but i'd also like the text color to change (which isn't responding).on the stage, the playlist items are built like this: dynamic text box songTitle, inside movie clip song#btn, inside movie clip playlistMC. The text below in bold is whats not responding. and for some reason when i change song6btn to song1btn, the text color does change for song1 when song6 is playing.[code]
