Spark list removeChildAt error
I'm trying to remove an item from the spark List called books like so:
books.removeChildAt(books.selectedIndex);
but i get an error when i execute the method:
Error: removeChildAt() is not available in this class. Instead, use removeElementAt() or modify the skin, if you have one.
it won't compile if i use removeElementAt() as the s:List does not have that method. i don't have a skin to modify either.
how do i remove the item from the list? thanks -brandon
remove the item from the dataprovider of the list.
list.dataProvider.removeItemAt(list.selectedIndex);

How Do You Populate A Spark List Control With An Array?
Hello, all,
Sorry to come accross so frustrated, but how in the name of God do you populate a Spark list control with the data in an array? You used to be able to do this with the mx:List control, but the guys developing Flex just had to make things more difficult than they need to be! I am more of a code purist and prefer doing things the way they have been done for decades, but apparently nothing can ever stay simple!
I simply want to populate a list control with an array and this shouldn't be rocket science! I found out that I must use a "collection" element, so I decided that an arrayCollection would be best. However, after searching Adobe's documentation about arrayCollections, I am lost in a black hole of data binding, extra lines of code just to add a new element, the need to sort it, etc...!
Here is my code:
var pendingArray:ArrayCollection = new ArrayCollection();
for ( var i:int = 0 ; i < queue.length ; i++ )
var item:UserQueueItem = queue[i] as UserQueueItem ;
if ( item.status == UserQueueItem.STATUS_PENDING )
pendingArray.addItem({label:item.descriptor.displayName,descriptor:item.descriptor});
Here is the relevant MXML:
<s:VGroup>
<s:List id="knockingList" width="110" height="100"/>
</s:VGroup>
I'm not getting any errors, but the list is not populating.
I have seen several examples where the arrayCollection is declared and populated in MXML:
<mx:ArrayCollection id="myAC">
<!-- Use an fx:Array tag to associate an id with the array. -->
<fx:Array id="myArray">
<fx:Object label="MI" data="Lansing"/>
<fx:Object label="MO" data="Jefferson City"/>
<fx:Object label="MA" data="Boston"/>
etc...
</fx:Array>
</mx:ArrayCollection>
That may be fine for an example, but I think this is a rare situation. Most of the time I would image that the arrayCollection would be created and populated on the fly in ActionScript! How can I do this?
Thanks in advance for any help or advice anyone can give!
MattIn your post it seemed like you were trying to take care of many considerations at once: optimization, design, architecture. I would suggest you get something up and running and then worry about everything else.
If I use data binding, then I will probably have to declare the arrayCollection as a global variable and then I'll have to write 100 or so extra lines of code to addItem(), removeItem(), sort(), etc... It just seems like too much overhead.
I believe you may have some misconceptions about databinding in general. You won't have to make it a global variable and you certainly won't need an extra 100 lines of code. If you did this forum would be a very , very quiet place.
I don't want to use data binding because the original array is refreshed often and there is one function called by an event that re-declares the arrayCollection each time, populates it with the array, and then sets it as the list's dataprovider.
That is the beauty of the ArrayCollection, it can handle the updates to its source Array. I don't know if you need to redeclare the ArrayCollection, resetting the source to the new Array allows everyone involved to keep their references so you don't have to worry about any "spooky" stuff going on. -
Need help with navigation within a spark list...
hey guys, so in my application when you click on a list item, it opens up an image, and along with the image a few buttons are created dynamically...
the image and the url/labels for the dynamic buttons is provided through an xml/xmlListCollection.

i have attached a copy of the xml that i have right now to this post for reference...
any help will be greatly appretiated!!! i've been stuck on this problem for the last week and my project is due soon
again thank you in advance...hey david... just nevermind my previous post... I was able to subclass a link button, so i now have two variables that get assigned to a link button,
one is "tabId" <-- contains the information on which tab to swtich to, and the second is, "changeTo"... this contans the label name which it needs to switch to
I'm just stuck on how to change my selected item in my tabNavigator/list
the code i have right now is

Extending a component which already extends a spark list ItemRenderer
Hello everyone,
I have the following situation: Im displaying lists of very similar data objects (they extend the same parent) so in order to avoid a lot of changes to many itemrenderers (if i need to change something in the common properties) when displaying this data, i defined a spark list ItemRenderer (in MXML) which displays the common properties (file called BaseRenderer.mxml):
<s:ItemRenderer>
//in the script section i override the set data property
//some MXML labels, checkboxes, etc
</s:ItemRenderer>
Then i created a specific itemrenderer which extended it (file SpecificRenderer.mxml):
<model:BaseRenderer>
//again i override the set data property
//some ADITIONAL MXML labels, checkboxes, etc
</model:BaseRenderer>
When i run the app, and when the specific renderer is used, it works (no errors are thrown) , but it only shows the content of specific renderer, nothing from base renderer is visible. Is this the right way to do this, or do i have to override some additional stuff in my specific renderers?
Thank you.
One more thing, i just noticed, if i remove all MXML tags from specific renderer, the content from base renderer becomes visible, seems as if specific content overrides base content. Is there a way to add mxml tags into the specificrenderer?Yes i suspected them to be merged, and you gave me a great idea. As you say this behavior is true across all mxml defined components, not just itemrenderers. I want to avoid actionscript renderers because i dont (and wont) have any performance issues anyway and i like flexibility in design view, so instead i found another solution which i slightly modified. Some spark components inherit property mxmlContent, which you can override. This is what i came up with in the end: I added the property override into specific renderer and everything is shown as expected (because base elements are merged with the ones from extended component).
override public function set mxmlContent(value:Array):void {
var adding:Boolean = true;
var index:int = 0;
while (adding) {
var element:IVisualElement = null;
try { element = super.getElementAt(index); } catch(e:Error) { }
if ( element != null ) {
value.push(element);
index += 1;
else
adding = false;
value.reverse();
super.mxmlContent = value; -
Paging data in Spark list component
I'm wondering if paging data for Spark list components will be available in the final release of FB 4 / Flex SDK 4? Currently you will get an error when trying to bind a paged service method to a Spark list component: "Paged operations are not supported by this component".
I'm asking this because of some problems we currently have with paging data in a Flex 3 TileList. See Jira issue: http://bugs.adobe.com/jira/browse/SDK-18758
The suggested solution in this issue is to use a Gumbo Spark TileLayout instead of a TileList. That's currently not a suitable solution since the list doesn't support paging...Hi Jacob and Ram,
Thank you for the information. Not the type of info I was hoping for of course . Do you guys know what I have to do to re-open my bug report (http://bugs.adobe.com/jira/browse/SDK-18758)? I'd really like to have the Halo TileList fixed so we are able to use it properly.
Thanks,
Jaap -
It doesn't seem like Spark's List controls are fully implemented; at the very least dataTips and dataTipFields aren't. This Halo code works:
<mx:List id="courseCatalog" dataProvider="{getAllCoursesResult.lastResult}" labelField="title" showDataTips="true" dataTipField="slug" ></mx:List>
but the Spark version:
<s:List id="courseCatalog" dataProvider="{getAllCoursesResult.lastResult}" labelField="title" showDataTips="true" dataTipField="slug" ></s:List>
yields these errors.
Cannot resolve attribute 'dataTipField' for component type spark.components.List.
Cannot resolve attribute 'showDataTips' for component type spark.components.List.
Is this a known issue?
--Mike JenningsCorrect, the mx:List and s:List components are two separate components and don't always have the exact same APIs. Most of the time the same functionality exists in both controls, but they may have slightly different names. I believe the latest Flex 4/ActionScript 3.0 Language Reference is posted at http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/ and should list which properties/methods/styles are supported by each component.
As for your dataTip question, this may work for you: http://blog.flexexamples.com/2009/08/15/creating-data-tips-on-a-spark-list-control-in-flex -4/
Not 100% certain about the variable row height, but I can take a look.

Hi, experts,
My background job 'Z1RM0063' couldn't open the spool list, the error as below:
' The selected section of the spool request 20,004
in SYSTME SID is empty.'
Who could tell me this is why ?
Thank you very much in advance,

MichaelHi Michael,
Its very difficult to tell... seems to be a custom job, what program is running?.. Does the spool that the job is trying to read still exists?...
Can you please post more details?

How to search XML data from a HTTPMultiService and display the result on the Spark List
Hello all,
I am totally new to Flash Builder and Actionscript and hope someone might be able to help me out. I basically create a mobile app with a single view. The view has a TextInput as a search box and a search button. I conntected a Data/Service using a local XML file and bind the Data to a Spark List. Innitally the List will show nothing until the user enter the search term and hit the button. The List suppose to show the XML data that match the search term.
Now is my problem. I cannot make the List to show the data that match the search text. The List just shows ALL the data.
Here are my MXML code:

Disable Spark List selection indicator
How do I get rid of the Spark List selection indicator entirely? I don't want the rectangular indicator when the mouse hovers over an item, and I don't want the color to change when the mouse is clicked.
You'll have to extend default item renderer (ItemRenderer for instance) and set autoDrawBackground to false. And then use your item renderer in a list.
See this document for more information on spark item renderers. -
Return data from spark list itemrenderer
Does anybody no how to return data from the itemrender for a spark list. say i had a checkbx in my itemrenderer how can I get that info back to my main component if its selected or not. I looked at datagrid and itemeditor but I really rather use a spark list. Thanks
thanks I also found another way to doing it. A click handler on my list when that fires I can check if checkbx has been selected by doing event.target.document.mycheckBx.selected this will not work if using currentTarget cause it take the info from the itemRenderer. Now I understand the difference between currentTarget and target.
not sure if this is a better way to access the data I think I might still just dispatch a event and do it your way.
Its weird that mx:list has a editItemRenderer and s:list does not
thanks again TK -
Spark List Itemrenderer items outside of List

You may test it with the following in your main.mxml
Bindable]
private var detailAC:ArrayCollection = new ArrayCollection([{value:"nteDevice.device"},{value:
"nteDevice.deviceTypenteDevice.loopbackIpAddr"},{value:
"nteDevice.ipAddressnteDevice.loopbackIpAddr"},{value:
"nteDevice.loopbackIpAddrnteDevice.loopbackIpAddr"}, {value:
"nteDevice.release"},{value:
"nteDevice.releasenteDevice.loopbackIpAddr"},{value:
"nteDevice.clli"},{value:
"nteDevice.provisionStatus"}]);
<s:List id="lst" itemRenderer="com.att.ntscp.view.component.ListRenderer" dataProvider="{detailAC}" width="200" height="200"/>
Is it a little bit trick?
