QtConcurrent using Variadic Template Arguments

[Keith Gardner]

I was wondering if QtConcurrent could be modified to use Variadic Template Arguments for the run function since this feature is now available with C++11?

I thought that work was done in Qt 4.8 already. Can you check?

I just looked through the qtconcurrentrun.h file for Qt 4.8 Beta 1 and did not find any variadic template definitions.

On a side note, I was just looking at Microsoft's information about Visual Studio 11's compliance with the c++11 specification (http://blogs.msdn.com/b/vcblog/archive/2011/09/12/10209291.aspx) and noticed that they don't support it anyways.

It would not be that easy because of the current implementation design of
QtConcurrent. (it would basically involve a rewrite of all the current
template logic)
Also, we have to keep it working with compiler that do not support C++11.

(I only see one benefit of having variadic template support: make possible to
call functions with more arguments. And that can now be done with a very small
boilerplate)

But QtConcurrent really could benefit from some love. Both the templated code,
but also the internals (to reduce the overhead of the framework).
