Flex :: Call A Function Inside ItemRenderer In A Spark List, From The Main Application?
Sep 1, 2011
I have a main application that contains a list, using a custom itemRenderer to display data.
I would like to be able to call a function, inside the itemRenderer, from the main application.
When running the app, we have a list with three persons, and a button. I want to call the function myItemRendererFunction() inside the itemRenderer, of the selected item in the list, all this, from the main app.
[Code]...

I am having an issue with my ItemRenderer, which I am using for a spark List. My code is the following:
I have this list:
<s:List
id="productSetList"
dataProvider="{ model.productSets }"
[Code]....
The thing is, if I scroll the list, and click on an item, it does not trace 'arthur' ! Why is this so ? I must trace that all the time that someone clicks in the list!
EDIT: If I remove change="model.selectSet( productSetList )" in the list, it works!! but I cannot remove that, some suggestions ? How can I switch that to another function?

In a flex project that I have that is designed to scale 100% to the web window, I have a spark list. And I have a simple itemrenderer that takes the data and displays a name, and a message. Just think of it like a simple instant messenger display. The problem is that for my msg_txt label I want to give it a width thats the width of the parent list thats holding it.I tried turning the horizontalScrollPolicy to off, also tried width="this.parent.parent.width}" (as well as this.parent.width) for the spark label inside the item renderer. and in the label i tried some things like left="0" right="0" maxWidth="{this.width}" but nothing really does the trick.How can I make this label have a max width of the list thats holding it, AND make sure it resizes if the size of the browser changes and the list size changes?heres the list:
<s:List id="chat_content" width="100%" height="100%"
alternatingItemColors="[#EEEEEE,#E6E6E6]" contentBackgroundColor="#EEEEEE"
horizontalScrollPolicy="off" itemRenderer="renderers.ActiveChatItemRenderer">

In Flex I can create an ItemRenderer to represent each item in the Lists DataProvider but how do I access the instance of the ItemRenderer via the DataProviders Object? Something like myList.getItemRenderer(dp.getItemAt(10));

I am using a spark list control with an itemrenderer. Whenever I set an itemrenderer's currentState, the moment I mouse out of the itemrenderer, it gets reset to its default state. How can I make an itemrenderer keep its currentState unless I explicitly tell it to change?

Objective:I would like to pass Skins to an itemRenderer (which is a Button) of a List, and be able to skin every button in that List.This is what I have:
List:
<s:List itemRenderer="renderers.ItemRenderer" dataProvider="{collectionWorkspace}" />
ArrayCollection:
<s:ArrayCollection id="collectionWorkspace">
<comp:Layout1 />[code]...
I get an error (fixed for clarification):Error: Skin for Application....Button1 cannot be found.

I'm writing a s:ItemRenderer to render some simple graphical components in my app. Each element can have multiple shapes that can be selected by the user, i.e. a certain element can be a square, or a circle, or a star, or whatever else.The simplest way I could think for doing this was to include all possible shapes in a s:Group and then manage their visible tag depending on what shape the user has selected. Is there a better way to do that? Also, if I encapsulate the group in a separate MXML component, how do I propagate the state of the itemRenderer (say "hovered") down to the MXML component that manages the shapes?Let's say you want to display three types of objects alternatively - the IR below with an AS snippet that turns visible to false for 2 out of the 3 objects definitely does the trick, but seems so ugly to me. In the mean time I found setCurrentState (stateName: String, playTransition:Boolean=true) to propagate the state down, so that's solved.[code]

I have a List with TextInput as item renderer. I want to get the value entered in the TextInput (form the TextInputItemRenderer) and pass it the main application to do some checks(upon tapping enter on the textInput -- see code below).
I know that we can do it thru dispatching event but I still don't understand how to pass a variable from the ItemRenderer to the main app.
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"

I've wrote a custom itemrenderer for a List component (Flex 3.5) which is a VBox with a Label and a TextArea wrapped inside. All works fine so far but I want the TextArea in the first itemrenderer to receive focus so that it instantly becomes editable when tabbing onto the List. Is that possible and if how would I achieve this?
I've already added an event listener that selects the item at index 0 but the textArea in it should also be focussed at that moment _list.addEventListener(FocusEvent.FOCUS_IN, onListFocusIn);
private function onListFocusIn(e:FocusEvent):void
{
_list.selectedIndex = 0;
}

I have an Application displaying a spark.List. Every item of my list must be visible (no vertical scroll).
I need my Application to be scrollable in a web browser, so I've add a Scroller containing all my components. When the browser window is too small to contain all my application, scrollBar appears.
My application looks like that :
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="100%" height="100%" >
[Code]....
When I scroll with my mouse cursor outside of the List, everythink works fine. When I scroll with my mouse cursor over the List, nothing happends.
It looks like the mousewheel event is stopped by the List, even if the List does not have a scrollbar.

I want to call the parent function called "edit_groups()" from the itemRenderer. The code for my itemRenderer is:
<mx:VBox id="vbx_container" paddingBottom="4" paddingLeft="4" paddingRight="4" paddingTop="4" borderStyle="solid"
dropShadowEnabled="true" width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
<mx:Canvas width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
<mx:Image id="image" width="100" height="100" source="{data.thumb}" scaleContent="true" maintainAspectRatio="true"
complete="{image_smoothing_handler(event);}" trustContent="true" doubleClick="{Call The Parent Function"edit_groups()"}"/>
</mx:Canvas></mx:VBox>
And I call my itemRenderer from an application like:
list_groups_modify.itemRenderer=new ClassFactory(groups.list_groups_modify_item_renderer);
<mx:Label text="{data.label}" textAlign="center" maxWidth="60" toolTip="{data.label}"/>

I am trying to create a generic List, where I can pass the layout & item renderer as parameters.Since it is not possible to pass parameters to a MXML component's Constructor, I figured I should create my List in Actionscript.
[Code]...
I would prefer to have the List in MXML (because It will be easier using states later), but If I am forced to use pure Actionscript so I can instantiate it and pass in parameters, any help would go a long way.

i have a spark list component and a corresponding custom itemrenderer:
list component:
<s:List id="albumImagesList" itemRenderer="the.namespace.for.XYZImageRenderer" useVirtualLayout="false" width="400" height="160">
<s:layout>
<s:TileLayout requestedColumnCount="5"
[Code].....
it's all fine and dandy, the data gets populated correctly and i verified that the data.image_path property arrives safe and sound inside the itemrenderer.
my only problem is: the image is not displaying. i am not sure if it doesn't render at all or if it's just not visible somehow.

now, fort right-to-left text i want in this itemrenderer, i would like to add a spark:TextArea component in this createChildren() function
is there a way to do so?
this is the itemRenderer:

I'm trying to make a horizontal list of labels with a space in-between them (for use as part of a ticker tape).Labels outside of a list have a transparent background but as part of either the ItemRenderer or List, they get a white background. My assumption is that this is part of the default styling applied to a Spark ItemRenderer.Question - Is there any way to totally get rid of all default visual stylings applied to an ItemRenderer?
protected var messages:ArrayCollection = new ArrayCollection( new Array("1", "2", "3", "etc") );

I'm trying to set a Spark list control to 100% height of a View inside of a TabbedViewNavigatorApplication.
<s:List dataProvider="{dp}" itemRenderer="renderers.Renderer" width="100%" height="100%" />
Using this I can't seem to get the list to fit to the view, it always ends up being much too tall.I'm testing using the Flash Builder mobile profile, the results seem to be the same across all phones. Setting the height to some number under 50% seems to bring the list closer to full width but it's not consistent across phones.
My app container is set for 160DPI
<s:TabbedViewNavigatorApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" applicationDPI="160" applicationComplete="init(event)">
I haven't come across this issue until I started using TabbedViewNavigatorApplication, 100% seems to work fine in a standard view based application.

In my main application I have a viewstack with 3 child views. In the viewstack change handler, I programmatically change the selectedchild property.
I understand that the initialize method for the view is not called every time I change the selectedChild Property. So I tried to invoke the init method programmatically too..

I'm trying to animate a list as I delete the top row. All the examples I can find use itemsChangeEffect to bind to the effect, but this property exists only in MX lists, not spark lists.
Any idea how I can get the same effect done in Spark Lists?
I'm trying to remove the top most item in the list with a slight fade out effect before the rest of the items move up to replace the gap.

I have an application with a Google Map, an Area Chart, and an accordion containing a list.When the selection in the list is changed, the application fetches data from the server and updates the chart and map, repositioning the map to contain all markers within its viewport and kicking off a SeriesEffect to animate the chart data redraw.When a user changes selections and continues to mouse over the items in the list while the map and chart are redrawing, the labels on the item renderers disappear.The item renderer code is the following:
<s:ItemRenderer xmlns:fx = "http://ns.adobe.com/mxml/2009"
xmlns:s = "library://ns.adobe.com/flex/spark"
xmlns:mx = "library://ns.adobe.com/flex/mx"
