Answering my own question... Yes QNAM handles receiving compressed
responses no problem.
Would still be nice to know how to enable it for sending compressed
requests?

You need to compress yourself and set the appropriate Content-Transport-
Encoding headers.

It looks like the current version of the ActivePerl (5.14.2 Build 1402
(64-bit)) has an outdated version of the GetOpt::Long module (2.35) which does
not have GetOptionsFromArray yet. The required version is 2.38. I just
discovered this myself while building Qt5 on a another PC…

This seems like it would be slow, especially when you started using haddrist

At the moment I have already solved with a Slot connected to the closure of the

that invokes methods to retreive data. But what are the best practices?
What are the pros and cons of every solution?

It depends on functionality you need and type of your dialog (modal/modeless)
In any case I do not think appropriate time is when dialog is closed.

I doubt that implementing moveable private objects/pointers would be
[really] useful.
Firstly, Qt can't control the location of the memory block allocated
by new/malloc, so the assumption that some [random] reallocations will
improve the contiguity of allocated memory looks quite naive.
I'll take that as a compliment. I fully expected someone to raise the issues
you did. And I will counter them with the following comments.
Yes, Qt would be less predictable, but more predictable than .NET's allocator.
If you want GC-like features, it'll come at a GC-like price.

Hi Jason,
If there are 5 public objects whose d-pointers reference the same private
object address, how are you going to update them when you relocate the
private object?
I don't think .Net stores addresses, just handles, so the relocate only
needs to update the handle info. That's
