How to dynamically add data in a Spark list control
Hi, I have a spark list in one of my custom components() control(id="Cclist") and a text input control. When a value is entered in the entry of the texts, I want to dynamically add the same in the list control. I tried to do the following:
protected function Cc_selectHandler(event:CustomEvent):void
{
var cctext:DisplayObject = event.data as DisplayObject
CcList.enabled = true;
CcListButton.enabled = true;
CcList.addChild(cctext);
}
But I get an error saying "addChild() is not available in this category. "Instead, use addElement(), or change the skin. So I tried to use addElement, but apparently it is not available at all. No idea what im doing wrong?
Add the text entered in the textinput to the dataProvider of the list in the appropriate format.
A simple example:
-
List of errors in the scripts of VI
Is it possible to see the list of errors to a VI created by the script of VI? The same preference list of error do you get when you press a button to run broken.
If a VI is created, but no executable, you get an error 1003 ("LabVIEW: The VI is not executable...") ") when you try to run it. But it does not specify what the problem with VI.
Now, I have to manually open the VI and check whats wrong. Y at - it another option?
Here's the method.

When you send an e-mail using Outlook Express, I immediately get this message; "Some errors occurred while processing the requested tasks. Please see the list of errors below for more details"
When you send an e-mail using Outlook Express, I immediately get this message; "Some errors occurred while processing the requested tasks. Please see the list of errors below for more details". Unfortunately, there are no errors listed below and the green bar is frozen on the screen. The message remains in my Outbox and repeated again and again sending. There is absolutely no record and file sent in my sent box. TIA - Ernie
You have apparent dbx file corruption. A common problem.
Spend most of your messages out of the Inbox and then create new folders to send and sent items box after having moved the messages you want to save to a local folder that you create.
Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.
In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.
With OE closed, find the DBX files for the items in the Outbox and sent and delete them. New ones will be created automatically when you open OE.
After you're done, followed by compacting your folders manually while working * off * and do it often.
Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.
General precautions for Outlook Express:
Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.
Disable analysis in your e-mail anti-virus program. It is a redundant layer of protection that devours the CPUs, slows down sending and receiving and causes a multitude of problems such as time-outs, account setting changes and has even been responsible for the loss of messages. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:
http://www.oehelp.com/OETips.aspx#3
Note that for some AV programs, it may be necessary to uninstall the program and reinstall in custom Mode and uncheck analysis when the option is the result of e-mail messages.
Compact often as specified above.
And backup often.

I get an Error Message When you try to send emails. "some errors occurred while processing the requested tasks. Please see the list of errors below for more details".
But it sends the message anyway... multiple copies, and she also is put in the "Outbox" in Outlook Express as if it is not sent.
To stop the email to be sent repeatedly to the recipient, I erase it from the "Outbox" but a) you don't know if they really got it) b it is embarrassing for the receiver c) is this a bug I can fix it?

Spark list ItemRenderer 'data' is null.
I use the same code in one place that I use in another, and still the event creationComplete that they prepare in the itemRenderer, the first line of code, trace("data") returns "null".
This code has been fine for months of work and suddenly stopped working with no explanation. I lost two days within period of fixation which should not be broken and I'm no closer to a solution. Very frustrated. Any help appreciated - greatly.

Looks like I'll change to use instead of the creationComplete dataChange in all my custom converters. I can't believe I lost 2 days and more hair because of something so trivial as multithreading.
Really... You cannot MAKE something before that data is passed and the rendering engine is INSTANTIATED ONLY when an element is added to the dataProvider... Then... the procedure. Data added to dataProvider-online Insantiate WITH object relevant-Online Layout/rendering/upgrade to day-online THEN creationComplete(); Duh. creationComplete is a misnomer if you don't even have the relevant data that you use to CREATE the instance.
No doubt this would be avoided if the BUG that places the dummy rendering engine IN the dataProvider have been set, but as it is - not, been resolved, I have no choice but to disable put in virtual. Sage, grumble, winge winge winge-grouse.

Custom spark list control
I have a spark list control that displays a dynamically imported Images tilelayout. Basically, a bunch of thumbnail Images that appear in a tile layout. I slipped active so that I can reorganize these thumbnails and everything works great except for one thing, the who. In my itemrenderer I included Image in the State "dragging", but the image does not appear in the who. I'm basically just has a square semi transparent like my, but I want to be able to actually drag my sticker. Any ideas how to do this?
Here is my list:
< s:List id = "ImageList1" x = "77" y = "95" width = "858" height = "412" dataProvider = "{imageAC}".
itemRenderer = "converters. ImageACSmallItemRenderer"contentBackgroundColor ="0x000000 ".

allowMultipleSelection = "true" skinClass = 'skins. General.ListSkin' focusAlpha = '0' mouseMove = "getImageProxy (event)" >

Thanks for any idea!
Hi Bill,
Looks like you create a new object for each ItemRenderer ContentCache, to create a single instance shared, add "static" like this:
static public var contentCache:ContentCache = new ContentCache();
This will ensure that the contentCache variable is shared between all of the ItemRenderers.
In addition, in my view, there is no need to explicitly call the contentCache like this:
contentCache.load(dataProxy.pathSmall);
Fixing the contentCache just the contentLoader on the Image property, the way you have done should be sufficient.
I just do a quick experiment and here is an example with an ItemRenderer that exposes the problem:
And here's workaround with contentCache (works well for me in the AIR):
See you soon,.

need help with change in spark list itemRenderer
Hey guys... so I have a spark list, where I've made available to tileLayout and I use the converter component to display an image and two buttons in each tile... what im trying to do is when you hover over each tile I want buttons fade in and out... and by default... I need to no visible buttons...
I had pimples fade in and out when you hover over the point... but the problem is that I have when I initialize the application buttons are all visible... If there is no sence...
any help is greatly appretiated!
Here is the code I have... can you tell me what changes I need to make...

Hello
With a lot of intelligence are already integrated into state transitions, when for example the transition fading knows when to fade in or fade out, get your components placed in the States you want is all that is necessary.
This is a simple example, but as you can see there is almost no code involved...

Spark list component Icon property?
in Flex 3.x the VBox property was property of the icon that you can use to set the images in the elements of the list as well as the label property. How can I get the same thing in a Flex 4 spark list component?
I would like something like 'iconField' property set to the list item, so that my itemrenderer can be generic and not worry for a specific type of object is passed in.
Thank you!
~ Mike
I have the subclass would list, add an iconField property and change the default
renderer a converter custom will check data [iconField] for a
icon and display it.

How to refresh a Spark list manually?
Hello
I'll build a News Module, which consists of a DataGrid and a spark with a customItemRenderer list.
When I click on the item in the DataGrid control, I get the 'newsID' of the item clicked and receive the newsDetails associate my data in an ArrayCollection collection.
This table Collection is the dataprovider for my spark list.
Okay, well, when I click on the first point, nothing works like it supposed to be.
But when I click the second entry, for example, the list of the spark is not following and display the changed data but the ArrayCollections are updating of data.
I checked in the binder to an another DataGrid that owns the ArrayCollection as a DataProvider collection.
So my question now is to know how to manually refresh a list of Spark.
On google I found that someone suggested to set the ItemRenderer of the spark to null list and re - declare.
http://www.mail-archive.com/[email protected]/msg132923.html
How would I do this programmatically?
= null myList.itemRenderer and that?
My custom item converter is called HListRenderer.mxml
Any help is very appreciated
Marc
Try:
myList.itemRenderer = null;
Group1.itemRenderer = new ClassFactory (HListRenderer);

How to animate a dataGroup spark list when the user travels through elements?
How can I get the dataGroup have an effect when the user travels through the list?
I came across this example that uses a HGroup:
olling-through-items-in-a-spark-hgroup-container/ http://blog.flexexamples.com/2009/11/11/Creating-an-Animated-transition-when-SCR
.. who is the exact effect I would like a list.
Taking the example of HGroup you posted you can do something similar with a spark list by animating the position of scroll on the page layout:
http://ns.Adobe.com/MXML/2009.
xmlns:s = "library://ns.adobe.com/flex/spark" >
Import spark.core.NavigationUnit;
protected function scrollToThere(dir:int):void {}
var value: Number = listLayout.getHorizontalScrollPositionDelta (dir);
If (value! = 0) {}
pth.valueBy = value;
Anim.Play ();
}
}

return data to spark list itemrenderer
Everyone is not how to return data from the itemrender for a spark list. say I had a checkbx in my itemrenderer how can we retrieve this info to my component principal if his selected or not. I looked on the datagrid itemeditor but I really use rather a spark list. Thank you
Hello
itemRenderer should be used only as RENDERER. All chenges must be made in the data.
So if there is a check box, you must add click eventListener and change the property in the data to see whether he is selected.

Extend a component that extends already a spark list ItemRenderer
Hi all
I have the following situation: Im showing lists of very similar data objects (they extend the same parent) so to avoid many many itemrenderers changes (if I need to change something in common properties) when displaying of these data, I've defined a list of spark ItemRenderer (in MXML) that displays common properties (file called BaseRenderer.mxml):
< s:ItemRenderer >
in the Scripting section I override the property data set
some MXML, checkboxes, labels etc.
< / s:ItemRenderer >
Then, I created a specific itemrenderer which extended it (file SpecificRenderer.mxml):
< model: BaseRenderer >
Yet once I override the property data set
some labels ADITIONAL MXML, checkboxes, etc.
< / template: BaseRenderer >
When I run the application, and the specific rendering engine is used, it works (no errors are thrown), but it shows that the content of the specific rendering engine, nothing base converter is visible. What is the right way to do it, or do I have to replace some extra stuff in my specific converters?
Thank you.
One last thing, I just noticed, if I delete all the specific rendering MXML tags, basic converter content becomes visible, that it seems as if a specific content replaces content base. Is it possible to add mxml tags in the specificrenderer?
Yes I suspected them to be merged, and you gave me a good idea. As you say this behavior is worth between all components defined mxml, not only itemrenderers. I want to avoid actionscript converters because I don't (and used) have problems of performance anyway and I like the flexibility in design mode, to remedy this, I found another solution that I slightly modified. Some spark components inherit the mxmlContent property, which you can override. That's what I came up with in the end: I added the override of the property in the specific renderer and everything is shown as expected (because the basic elements are merged with those of the extended component).
override public function set mxmlContent(value:Array):void {}
var added: Boolean = true;
var int index = 0;
so that {(addition)
var element: IVisualElement = null;
try {element = super.getElementAt (index) ;} catch(e:Error) {}
If (element! = null) {}
value.push (element);
index += 1;
}
on the other
Add = false;
}
value. Reverse();
super.mxmlContent = value;
}

Problem with spark list and XML dataProvider
I am VERY new to Flex so I'm probably doing something wrong, but I hope it means this will get a quick response.
I use a list of spark related to a data provider. On the actions of the user, the list will be filtered. The problem I encounter is that when the xml result is one, she will eventually launch an error:
