onCreate methods are very important when you want to add some java code
before the Qt application is loaded. Because onCreate must call
"super.onCreate(..)" it is impossible for the user to do anything before
Qt is loaded. By using the onCreateHooks to load Qt, the user can
decided, by overriding the onCreateHook method, when or if Qt is loaded.

QWindows that aren't created, and therefore don't have a platform window
attached, should not be treated as "normal" windows. The expectation,
in our code, is that these windows won't get their geometry updated by
the platform plugin, and that the geometry is only changed by the owner.
In QQuickWidget's case this was causing the scene to be rendered
incorrectly.

Instead of calculating the bytesAvailable in place, the value should
be stored and only retrieved in the function itself. Otherwise it is
possible that bytesAvailable is called between the data having been
read and readyRead is emitted. In this case it's possible, that the
client reads all the data before the signal is emitted. Triggering
readyRead without any data being available will stop the socket.

We may only emit the readReady signal once for every event loop
iteration. The previous implementation lead to the situation that the
socket engine stopped reading socket data when bursts of data was
received. In this case several readReady signals were fired. The socket
engine obtained the pending datagrams (not only the first one) and for
the following readReady signal no datagram was present. In this case the
socket engine stops reading and the engine stalls.
The new approach emits the readyRead signal at the most once every event
loop iteration. The list of new pending datagrams is queued to be added
to the "real" pending datagram list at the same time as the readyRead
signal. Thereby we avoid the situation that a client can read all the
datagrams before readyRead is emitted.
One more advantage of having the worker handle the pending datagrams
is that we no longer have to access the socket engine's members inside
the callback. Thus we avoid the situation, where a late callback can
make the application crash when the socket engine has already been
deleted.

The old code fell through into from the CE_RubberBand case into the

Quite obviously, the drawing of a rubber band was requested by the
caller, drawing a size grip instead must be considered a bug,
regardless of any additional guards employed by the size grip case.
So, fix by removing the conditional return in the success case and
adding an unconditional break. The function ends after the switch,
and all other cases also break instead of return, so consider the
switch from return to break a contribution to the internal consistency
of the function.
