Instead of using selectByDataItem, you need to use the FlexWheel.selectItemAt(boxIndex:int,val:Object).
boxIndex is 0 unless you have more than one “column” (spinBox).
val is the object in the dataProvider you want to select.
There is one important issue to note, each spinBox has a compareFunction property (to compare items in the dataProvider).
By default this property is set to Flex ObjectUtil.compare (see flex docs). In my experience, In complex objects it does not compare well.
You can set your own compare function in your overriden handleSpinBoxCreation() function.

Hope this helps
Cheers

Hi!

Great component but I seem to have run into a small problem: after setting a specific item (using selectByDataItem) it seems that the previous item is selected instead of the requested one. Could you verify this please?

Thanks in advance,
Tom

Sorry, not 508 accessible, It’s an interesting idea though.
About the mouse wheel. It already works mostly. See 7 posts back when I wrote about the mouse wheel.

Any chance that this component is 508 accessible?

As in.. you can tab to it, and use the arrow keys to navigate it, and a screen reader would read out the values in it?

The only reason I’m asking is because we need our app to be 508 compliant…

Also, when a component has focus, can the mouse scroll wheel scroll the spinner? This is not as much a 508 issue as a “would be cool” issue

Sorry, It does not have an automatic scrolling mode but you can check out the
containerEx library HSmoothBox and VSmoothBox I have for download on my site here
http://strawberrypixel.com/blog/flex-components/#hsmoothbox
it’s free and open source. Most likely you can set up a timer that calls the scrollToItemIndex
function.

Can the flex wheel be set to scroll automatically without using a mouse? I am looking for a way to scroll through list items automatically.

Yes you can remove the event listener of the Mouse Wheel from each VSmoothSpinBox inside the FlexWheel, there are a few ways to do this, one would be to save reference that returns from addSpinBox(…) and do a
ref.removeEventListener(MouseEvent.MOUSE_WHEEL, ref.onMouseWheel);

I will add a more “clean” way in the next version (property or something).

Thanks for the feedback

The mouse wheel was the first thing I tried when I was playing the component, and although it did not work right now, I’m confident that a resolution for that bug/feature will present itself soon.

Overall, I really like the look/usability of this component.

My only question is if it is possible to disable the mousewheel event if a developer so chooses?
