PendingDrag

public class PendingDrag extends Object

PendingDrag collects all the information related to an in-progress drag of a BlockView. It is initialized by Dragger, passed to a Dragger.DragHandler which calls startDrag(View, BlockGroup, ViewPoint) to inform the Dragger how to complete the rest of the drag behavior.

public void startDrag (View dragInitiator, BlockGroup dragGroup, ViewPoint touchOffset)

This sets the draggable BlockGroup, containing all the dragged blocks. dragGroup must be a root block added to the WorkspaceView, with it's first Block added as a root block in the Workspace.

Parameters

dragInitiator
dragGroup	The draggable BlockGroup.
touchOffset	The touch offset from the top left corner of dragGroup, in view pixels.
