[flexcoders] How to restrict Drag and Drop to one axis? (like the X-Axis only)

[Archibald]

This is super easy using startDrag and seems to be stupid hard using the 
DragManager.


Am I missing something?


Why would this relatively common need not be addressed in the DragManager?


I have seen like 20 people ask the same question with no answer.


I am working on a linear editor using an HList and want to use the built in 
DragDrop support but it has to restrict to only drag horizontally.



Thanks.
