A synchronisation lock for manipulating and updating the application and its widgets outside of the event loop.
You need to get this lock only when you want to manipulate widgets outside of the event loop. Inside the event loop, this lock is already held by the library itself.

Copy constructor.
By copying the lock, the lock is transferred. The original object becomes empty, and its destructor has no longer the effect of releasing the lock.
