There isn't one - although you can use 'execute script' to use LCS's
Indeed, I should check whether LCB does currently use an implicit lock
screen - it probably should as LCB handlers, when called from LCS, are
meant to be 'atomic' in some sense.

Screen updates of widgets only happen upon request from the widget - by
using the 'redraw all' and 'redraw rect' commands. Any updates all fold
into the update mechanism LCS uses and occur at a suitable point after
returning from LCB to LCS - this is the same as calling any engine
command / function.
Can you elaborate on your use-case here, just so I can check there isn't
something we are missing? :)
