5. Is it necessary to call lock screen in myUpdateGeometry and
dispatch “refreshChart”?
No - the screen is implicitly locked before the resizeStack message is
sent, and unlocked afterwards. Then the screen is explicitly updated.
Does having a lock and unlock screen pair in refreshChart have any
detrimental effect when it is called from resizeStack?
The screen lock mechanism uses a counter. So as long as all your lock
screens have a matching unlock screen which is executed then they will
have no effect (due to the fact the counter will already be 1 before
your resizeStack script runs).
Does having a lock and unlock messages pair in refreshChart have any
detrimental effect when it is called from resizeStack?
Again, the message lock mechanism is counter based. So as long as they
are matched there would be no outward effect - apart from not having
messages sent to your objects by the engine whilst the count > 1.
Will try to put together a test stack and video grab of the screen
flash.
I am using an iMac, El Capitan.
Thanks!
Mark.
