create a custom itemrenderer in Flex, whether there is some way to access the components that you place within the itemrenderer using actionscript? For instance, if I create a custom itemrenderer like this one:
<mx:itemRenderer>
<fx:Component>
<s:Group id="ThumbnailContainer" width="75" height="75">

Is there a way that I can access the "Group" container for each of the tiles that the program produces? So if I create a TileList, use the item renderer above, and have a dataprovider with 10 elements in it, is there a way that I can access or address the Group container for each of the 10 tiles that are created using actionscript?
I have made the following item renderer in mxml, but when I use it in a list for some reason I can not select it. Am I doing something wrong?

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
View 1 RepliesI have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?

View 1 Repliesow do you display HTML formatted text in a Spark custom item renderer (Actionscript)?
Sample Code:
The html content in item.post_content displays as plain text in the IconItemRenderer messageFunction snippet below (which is just the default generated code for Icon Item renderer):

<s:IconItemRenderer iconField="iconField"

I made the transition to AS3 two years ago, but I still carry with me old AS2 habits. Could someone please help me understand how I extend a custom class correctly. I have the bad habit of putting most of my code in one .as file (the Document class), but I use a few custom classes now and then. What I'm tring to figure out is how I would extend a class of this type:
public class ClipDragger {
private var _clip:MovieClip;
public function ClipDragger(clip:MovieClip) {
_clip = clip;
[code]....
For example I would like to add a MOUSE_MOVE listener, and also add actions to the drag function.
extending Object on a custom class that would normally be unextended?
package qnx.notificationManager
{
public class Notification extends Object
{
I've got a simple class:
package somepackage
{
import flash.display.MovieClip;
public class NewMc extends MovieClip{ public var myVar:String = "something";}}
And there is a question now: how can I assign a "real" MovieClip object to my created-class object?
I mean: var realMc:MovieClip = new MovieClip();

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;

This is my first time working with a class attached to a movieclip that is nested inside a class attached to a movie clip.I've tested all the properties and methods of PTListItem.as and they work properly but when I try to call them on the list item through PTListTop.as it returns undefined.The end goal is to dynamically load a checklist via a txt file.

Now the code works fine but when i write my own (sealed/fixed) Box Class that surely Extends MOVIE-CLIP, statement-2 gives error , i know the Box Class is not dynamic but the Movie-Clip is Dynamic.

View 4 RepliesI have a Datagroup with a custom item renderer the momment I bind it to XML from an http service it stops working.

I have an XML object in Flex4 that is populating a tree (amongst other things).
I need to be able to find the name of the selected item when it is clicked in the tree.
For example:
<Object id="">
<Image></Image>
<Cycle></Cycle>
[Code]....
The tags are all predefnied by me so I will know what they are, but I need to be able to know if the item a user has selected is "Object" and do something, or if they select "Action" do something else.
What is the syntax to get the names of these in flex4 and compare them?
I'd like to have an overlay that draws lines between selected items in different Flex 4 List controls.
The problem is I can't figure out how to access the x, y coordinates of the list's item renderers.
my renderer contains a canvas in it, i add some title-window, every time i see my tree previously added Title-Windows are visible, i want to access each n every item in tree and remove previosly added all windows from the rendere. how access all the item renderer in AS3 ?

I have an mx:tree with with TreeItemRenderer as below.
Parent1 (Delete | Rename)
Child1
Child2
Parent2 (Delete | Rename)
Child3
Child4
Delete and Rename are link buttons
Now when i click Rename a popUp should be shown like
OldName : Parent1(Text Input showning present Name)
Enter New Name: Parent1NewName(Text Input for entering New name)
OK | CANCEL Buttons
Afetr Entering the new name,click OK,popup should be closed and need to get the value in the treeItemRenderer.
I have the logic to rename the Parent1 in TreeItemRenderer and also I m able to get the Parent1 in the popup OldName TextInput.But after entering the new name i m not able to get that new name in the TreeItemRenderer.
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.
