ActionScript 3.0 :: Move An Item Within An ArrayCollection?

Oct 18, 2010

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.

Flex :: Edit ArrayCollection Through Item Renderer?

Jun 16, 2011

I 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.

Jul 27, 2011

i 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

itemRenderer="components.displaynews">

Android :: Retrieve Objects Item Information From ArrayCollection?

Aug 26, 2011

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;

Flex :: Reverse Order Of ArrayCollection So That The Last Item Appears First In A ComboBox

Jan 26, 2011

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.

ActionScript 3.0 :: Move One Item In The Movie As The Browser Window Resizes?

Jan 16, 2010

I've got a movie with a "next" button. The movie is approximately 1330 px wide. The "next" button needs to move left and right within that width as the browser window is resized. For instance, the browser window starts at greater than 1330px wide so the "next" button is at the far right edge of the movie. The user then resizes the browser down to 800px wide. The "next" button needs to move left to 800px. The entire movie can't resize, only the "next" button in that movie must move.

Here's a link the movie as it currently is. The "next" button shows up after the 2nd click in the sequence. It's the brown arrow on the right. http:[url].....

Flex :: Mxml - Components Bound To Empty ArrayCollection At Load Time Don't Render As Expected When The ArrayCollection Is Updated?

Oct 27, 2009

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" >

Flex :: Get List Item Selection Working When Using A Png Mask In An Item Renderer In A 4.5 Mobile App?

Jun 10, 2011

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;

ActionScript 3.0 :: 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?

Jan 2, 2010

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;
