Drag after long press only, so I can scroll with one finger

[Glen Pierce]

I have a FlowPanel that contains several FlowPanels that have all been madeDraggable. I want to handle a one-finger scroll event on touch devices (I know that two finger scroll is possible). The problem is that the FlowPanels that are draggable are always intercepting the OnTouchStart Event and they start dragging instead of allowing the FlowPanel to scroll.

Is there a way to set a delay on the OnTouchStart Events that are being called by the MouseDragHandler so that items will only become draggable after a long press?
