You could write your own SnapToHelper to constrain the possible target locations
when your editparts are being dragged.

(The DragEditPartsTracker which arranges the standard constrained move seems too
well protected against customization ?)

If theres a more orthodox way to implement a custom constrained move, I'd be
glad to know...

Regards,
Alex

Very Thanks,

I have modified the method "public DragTracker getDragTracker(Request
request)" of my editpart to return my owned DragEditPartsTracker in which
I rewrite the updateTargetRequest() method.
