Changing the scrolling amount of a spark DataGrid when using the mouse wheel

Question

Basically what the title says. I checked DataGridSkin, and it has a Scroller skin part, but I can't find any attribute for the scrolling amount. I might have missed it. Can anybody please help me on this issue? Thanks.

Answer 1

I found a solution: I used the idea described above, but instead of creating a class that extends VScrollBar, I added a MouseWheelChanging event listener to the scroll bar in the Scroller skin:

<fx:Component id="verticalScrollBarFactory">
        <s:VScrollBar visible="false" mouseWheelChanging="outerDocument.vScrollBarWheelChanging(event)"/>
    </fx:Component>

internal function vScrollBarWheelChanging(event:MouseEvent):void
    { event.delta/=Math.abs(event.delta); }

You can set event.delta to the desired scroll amount.
