notify components when their global coordinates are changing

[Cristina Constantinescu]

Hello,

Is there a way to notify children when parent changes its 
dimensions/coordinates?

For the moment, my solution is to add a resize event listener on parent.
When the event is dispatched, the child gets its global coordinates and 
uses them to position some additional components.

Is there another approach for this?  (like each child to be notified 
somehow when their global coordinates are changing)

Thanks,
Cristina
