The WidgetDropEvent object holds 3 anonymous arrays: entities,associations,documents, any/all of these may have data in them.
It also holds some information on where the drag came from:
dragSource: the dragger manually specifies this, can be anything
dragWidgetName: the title of the widget the drag came from
dragWidgetClass: the class of the widget the drag came from (i.e. the mxml file name of WidgetModule)
To send dragged items to another widget, dispatch an drag event with the dataformat using WidgetDragUtil.WIDGET_DRAG_FORMAT:

for each ( var doc:Object in docList.selectedItems )
{
docs.push(doc);
}
var dragObject:WidgetDragObject = new WidgetDragObject();
dragObject.documents = new ArrayCollection(docs);
dragObject.dragSource = "MyCustomWidgetName"; //this is the user made drag name, can be anything
var ds:DragSource = new DragSource();
ds.addData(dragObject, WidgetDragUtil.WIDGET_DRAG_FORMAT );
DragManager.doDrag(dragImage, ds, event);
