 Dear All,


We have a usecase similar to the attached sample image (Reference:
http://www.bmw-carit.de/open-source/genivi-layermanagement.php)


*Use Case:*
Three surfaces in same layer(1000)
HMI (Surface-100):Transparent and visibility enabled
Navigation Overlay(Surface-101):Transparent and visibility enabled
Navigation Mapviewer(Surface-103):Navigation Content

*Observed Behavior:*

1.HMI (100) receives touch events when HMI's(100) visibility is 1.

2.Navigation Overlay (101) receives touch events only when HMI's(100)
visibility is 0.
3.Navigation Mapviewer (103) receives touch events only when HMI(100) and
Navigation Overlay(101) 's visibility are made 0

*Expected Behavior:*
Touch Inputs to reach Navigation Mapviewer(Surface-103) even when HMI(100)
and Navigation Overlay(101) are visible.(Method to control touch events
irrespective of visibility of other top surfaces). Even when HMI(100) &
Navigation Overlay(101) are visible Navigation Mapviewer should get the
Touch events.



Kindly guide us in achieving the expected behavior.



Thanks and Regards,

Abhirami V
