Flex :: Spark ItemRenderer Not Showing Contents?
Mar 1, 2011
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.

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));

have been working on an air app for quite some time and in one of my mx:lists i have a custom renderer written in pure AS (no mxml). it extends the listitemrenderer mx componenet. in it i have overrode the createChildren() function to add some children of my own.
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:
import flash.text.TextField;
import mx.controls.listClasses.ListItemRenderer;

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") );
<s:List dataProvider="{messages}" itemRenderer="SimpleTextRenderer">
<s:layout >[code].....

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?

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 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?

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 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"

I would like my spark ItemRenderer to be able to render a varying number of graphical objects that depends on the user input. As an example, let's say that I want to render a set of ellipses on a line.I've been using MXML for my most recent batch of ItemRenderers and have loved every minute of it, but I'm not sure how to accomplish the above goal with an MXML IR. In Actionscript I can acquire the list of ellipses locations and draw them programmatically in the updateDisplayList method. Is there an equivalent in MXML?

I've got a DataGrid in my mobile application (I know, I know but there's currently not other solution for this), that numeric values. Depending on the value of a cell, the text gets colored. My big issue is that this doesn't work very for more than about 5 rows of data. I reckon the issue is that the set text function (in which I format the color) can't keep up with the amount of cell changes and formats the text based on the last updated cell of the row.I thought about a column item renderer so that the renderer only gets the value for that column, and not the whole data of the row.
Just for reference, this is my current item renderer (again, this works fine for few rows, for 5+ of fast changing data, this doesn't work any more, cells get formatted even though their data hasn't changed).[code]I just double-checked and have to revert my previous statement. A single row works fine, the second row already messes up the color formatting though. It seems as if the datagrid somehow throws together the values.
Doing the color formatting in the set data method shows the exact same effect;[code]My assumption about the grid messing up the ItemRenderer's data seems to be correct.A simple trace in the set data method (trace("old: " + _oldVal + "new : " + value[column.dataField]);) revealed that somehow, values of the next grid row (in case there are 2) get used as well as _oldVal gets the old value of the next row.

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.

I am going through the flex in a week training and I'm trying to use the Spark form in Flashbuilder 4, but it does not appear in the components windows. When I drag a form from there it is an mx form control. The project is set to use the 4.5 sdk and I can even create the tag in the code view, but when I do that is doesn't show up in the designer... How can I get the spark form control to either show up in the designer when created in the code view, or get the control to show up in the components window so I can drag it in?

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 am trying to use the same custom renderer for all the columns in a spark DataGrid. I need to know the dataField or columnIndex based on which I can change state in my custom itemrenderer.
Earlier in mx:DataGrid, this can be achieved by extending the MXDataGridItemRenderer which implements IDropInListItemRenderer and hence dataGridListData property is available.
But using the spark DataGrid, I am extending the GridItemRenderer which DOES NOT implement the IDropInListItemRenderer and hence unable to access dataGridListData property. I have tried to write an action script class extending GridItemRenderer and implementing dataGridListData but flex throws an error in the set function of this variable.

This is what what my screen looks like:
It is composed like this :
First container <s:HGroup>(900 X 100)--top black area
Second container <s:Group> (900 X 475)--middle white area
Third container <s:HGroup>--(900 X 100)--bottom black area
If the project were done with Flex 3, the middle area would be an <mx:Canvas>.
Now suppose I have one BorderContainer(125 X 475) and name it middleContainerChild. It is located on the right side of the middle area. When I set its y postion to -middleContainerChild.height, it should be located at y = -475, outside of the container's body. And as you can see in the image above, it has been placed there.
But other than with <mx:Canvas>, the image still shows, even though it is no longer within the <s:Group>s body, and it is rendered "on top" of the <s:HGroup>.
See the image below for more clarification:
If I use <mx:Canvas>, it is hidden away properly, but if I use a Spark container (not only a group, but any Spark container), it remains visible.

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">

I'm using the Spark DataGrid for the first time and finding it generally very usable.There's something I'd like to do with the contents of my grid now that I've drawn it though and I'm a bit stuck as how to proceed.I'd like to make a function that runs through each cell of a certain column in the DataGrid, that checks each value against an Array of predefined values; if it finds a match, it should then highlight the cell as conflicting, by changing its colour.I know you can access a particular cell's item renderer, by using the getItemRendererAt() function, and passing the column and row indices. But I can't see how I would, for example, loop through the values in each column

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:

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.

I have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.

I have built a simple Flash application that will be presented using a projector, the application will show messages in the form of questions that will come from a simple flat-file text file or XML file.
In addition to this I would also like to be able to add my own messages using a simple HTML form.
I've been looking around the web for some resources, but have been struggling to find what I am looking for. The basic idea is that the flash application will loop through these different messages from the XML, but then when a user types in a message that will also appear within these messages. Think of it as a sort of dynamic tag cloud.

I want to create a list of progress bars and update the list accordingly.I have group data in an Array as
<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....
The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as
<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>
Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").

I can change the name, but don't know how to delete just the contents of the layer and then add the new clip.I've made a slideshow before and that's all I can do.

How can we navigate within an itemRenderer? For example, in Views we use the View.navigator (ViewNavigator) to push and pop views, there is no such feature in ItemRenderer.
Navigation within a View (Easy)
<s:View>
<s:HGroup >
<s:Button label="Questionnaire" click="navigator.pushView(view.QuestionnaireCategory1View)"/>
</s:HGroup>

I have a List which has TextInput as itemRenderers for all its items. Upon application launch the items are rendered in the TextInputs correctly. The data is being populated from an Array of Objects.
What I want is, after the data has been populated in the ItemRenderers, I want to have an additional item renderer (TextInput of course)...so that if the user wants to enter another item, he can put it in the additional textInput.
And I also want to add the additional itemRenderer each time the user has added a new item and taps ENTER on the newly added item.
Below is my itemRenderer, there is the clearTxt_enterHandler handler..but I wonder how to add another itemRenderer upon "Enter".
