In Qt4, I implemented this by granting special access to
qMetaTypeConstructHelper to allow Qt's guts to access the "copy"
constructor (which is actually a move ctor, but this code predates
C++11). However, it seems in Qt5 I have to poke into the

No. If you connected two slots to the signal, which one would get the pointer?
The problem is that the answer makes no sense, which means move-only types
make no sense in signal parameters.

Thanks, will check it out and try to transfer to PySide2

Thanks.
I am not sure I agree with your dislike of overriding the paint method.
I have actually had to do this a lot for custom UIs an in some cases
even did it to make widgets more efficient.
I do agree that I prefer not to in cases like this though, so thanks for
your suggestions.
Cheers,
I have a class¹ that implements a "transferable" pointer. The idea is
that it is memory-managed, but can be used in signals/slots without the
overhead of an atomic reference count. It is a "throw it over the wall"
type of thing, the idea being that once it is emitted as a signal
argument, the calle

I'm now numbering my crazy ideas. That may in itself be a crazy idea, if so,
that's 2019-0.
2019-1 is that Qt Blog posts (blog.qt.io) should be included in the
documentation ,cross-referenced with the classes mentioned within. For example,

Hello all.
I’m trying Qt::AA_EnableHighDpiScaling with app that has a
QQuickFramebufferObject. Now, I create the FBO inside
createFramebufferObject(const Size &size). The value of the passed in size is
twice the size of the QQuickItem that contains FBO.
Now, I have the item size set to 100x100
Yes spinning a system thread(pthread) and then creating the application
object. On sigterm, quitting the application using quit() and just before
quit() deleting QApplication Instance and then pthread is cleaned up using
