Note that if your MyEvent class allocates memory (e.g. through a
pointer-to-implementation pattern), then you will have to implement
custom copy semantics.
\section1 Other classes
In Qt 5, QCoreApplication::quit() was equivalent to calling
\l{QCoreApplication::exit()}. This just exited the main event loop.
In Qt 6, the method will instead try to close all top-level windows by posting
a close event. The windows are free to cancel the shutdown process by
ignoring the event.
Call QCoreApplication::exit() to keep the non-conditional behavior.
