I have created a custom layout to lay elements out in a especial way.
But I want to enable mouse wheel function. Let every element move like in the path when they are staticed.
I try to change the verticalScrollPosition or horizontalScrollPosition but the result is not what I imaged.
So should override some function to achieve that ?
I think you'll want to override getElementBoundsLeftOfScrollRect() etc. This post has a code sample that does that: http://flexponential.com/2010/03/06/learn-how-to-create-a-simple-virtual-layout-in-flex-4/
