Public bug reported:
PointerBarrier is an important part of the desktop specification for the
Precise cycle. It creates an XPointerBarrier with additional logic to
detect if a mouse is pushing against the barrier, triggering Launcher
reveal if over a certain pressure, and causing the barrier to drop if
over a higher pressure.
This feature is currently in place in Unity. So for feature parity,
Unity 2D needs this also.
Please find the ready-to-merge MR for this feature attached to this bug
report.
Testing is 2-fold: first there is a comprehensive unit test of the
PointerBarrier class, which runs inside a fake Xserver and manipulates
the mouse to ensure the barrier operates properly.
Second, our automated UX tests have been updated to reflect the change
from Mouse-over area to PointerBarrier, and all previous behaviour of
the Launcher is maintained
Please find pbuilder logs attached.
