qt.network.ssl: No functional TLS backend was found ?

[SGaist]

Well, I must say I fail to understand your architecture here.

What is so speed critical in your app that you need to have your UI in C++ while doing some processing in Python while the rest is done in C++ again.

Data from stock exchange terminal - through с++ & qt, analysis in Python.

[SGaist]

Why not load the data directly in Python using something like numpy ?

[BVladimir]

It is assumed that there can be over 10,000 changing values on the screen once per second. I would like to have fewer lags.

[SGaist]

If you do all the heavy lifting in Python you should benchmark the GUI as well.

[BVladimir]

Maybe, but if it is possible to execute all gui in native c++, wouldn't it be preferable?

[SGaist]

As I wrote: benchmark.

Adding a layer of complexity might not be of any benefit in terms of performance, maintainability and architecture.

[BVladimir]

In any case, I already have a dll for getting data, and I thought it was the easiest way to use it for the gui... But with python, I'll have to do more research...

[SGaist]

Wait... you are loading the data from C++ then do processing in Python and then trying to send that back to C++ ?

[BVladimir]

Yes, some data for analysis in python, and some I would like to leave in c++ for gui

[SGaist]

Then wouldn't it make more sense to do it the other way around ? Since you get data through a C++ library, it would make more sense to invoke your Python code from C++ as well.

[BVladimir]

Well, if it is impossible to use dll for gui, then I will have to write c++ exe and provide interaction with python...
