Subject How to make a container automatically scroll when dragging a component reaches its border
Date Thu, 20 Aug 2015 14:09:48 GMT
Hi,

I have a VGroup with a Scroller that has a few child components, one of
which is a List. When the List is too long, users need to use the scroll bar
up or down to see all the rows in the List. Users are also allowed to drag
and drop the rows in the List to arrange the order. My question is, when the
List is partially shown and one needs to drag a row to the bottom of the
List that's currently not inside the view, is there anyway to trigger the
scroll bar to move up or down when the dragged row reaches to the border of
the VGroup?

Thanks for the help.

JL
