Hi,

You can tried to replace the rollOverColor or contentBgColor by a data.getStyle(‘color’) and set a color in the spark List.

The copy paste of your item rendered complains about and flash builder an not show it in its auto-completion. Any suggestion?

Even commenting it will give errors on undefined rollOverColor, contentBackgroundColor and selectionColor, what is going on?!!

…….
override public function set labelText(value:String):void
{
super.labelText = value;
labelDisplay.text = labelText;
}

……

Yes, with Tim Staller say, it runs. I am under SDK 4.0.0.7573
But why it became so difficult for a simple ItemRenderer?
For a speed of execution faster? And why overriding the label?
What returns to complicate such a simple itemrenderer to a list?

Thank you to those who want to point me to an explanation and where I can learn.

I was also getting the ‘method must override…’ error. I guess the getter/setter names in ItemRenderer have changed from ‘label’ to ‘labelText’. Here’s the script block with the modifications I used to get the sample working:

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

Andy,

A lot of stuff has changed since the beta build. Download the latest Flex 4 Nightly build and try again.

If it still gives an error in the latest build, let me know and maybe the API has changes since I did this example.

Hi, copied and pasted code but compiler is grumbilng that there is no set label method to override in ItemRenderer – i.e. 1020: Method marked override must override another method.

I’m using the beta standalone – not sure whether the class has changed in the nightly builds or whether perhaps there is a code error here?

Doron Katz,

You can refer to the Flex 4 beta documentation at http://livedocs.adobe.com/flex/gumbo/langref/spark/ and look at the Skin States section, or you can look in the default Spark skins.

For example, for the Spark Button control, go to the following URL:
http://livedocs.adobe.com/flex/gumbo/langref/spark/components/Button.html#SkinStateSummary
If the skin states table is not visible, click the “Show Inherited Skin States” link to see the inherited skin states. You should see the four states as: “up”, “over”, “down”, and “disabled”.

The other option is to look in the Spark skin itself. Personally, when creating a custom Spark skin I usually start by copying the default Spark skin and making modifications. For example, for the default Spark Button control skin, go to the following path in your Flex SDK: <Flex SDK>\frameworks\projects\flex4\src\spark\skins\spark\ButtonSkin.mxml.
You should see the following states defined in the MXML code:

Also, I should mention that the Flex 4 SDK Downloads page now includes nightly versions of the Flex 4 Language Reference. To download the latest Flex 4 SDK and the latest Flex 4 Language Reference, go to http://opensource.adobe.com/wiki/display/flexsdk/Download%2bFlex%2b4.

Hope that helps,
Peter
