I have questions:

  1. Which C++ std used when building code in TouchGFX Designer? c++11, c++14, c++17?
  2. Which C++ std used when building code in MSVC simulator? c++11, c++14, c++17?
  3. Which c++ std ST used to verify and release TouchGFX?
  4. Can user change and modify the std? Any risk/ side effects to consider?

Hello @CTapp.1 ,

Concerning the version of C++, TouchGFX only uses C++98 language features. Therefore, compiling the project using newer language versions should be safe. 

I hope that answers your question.
Regards,

Did you ever find out which versions are supported?

My generated STM32Cube project uses C++14, but I would like to use C++17.

The project builds without errors using C++17.

    Update: in TouchGFX 4.26.0 C++17 is default. https://support.touchgfx.com/docs/miscellaneous/known-issues#touchgfx-4-26-0

    I have used C++17 before this version without any issue.
