​** What I suggest is to use VoidPtr

    • Regarding PyPy support: found some issue. Will open a bug report.
  • Samuel
    • wheels for ARM?
    • Soon! Qt6 is arriving in Debian Testing, so once that's done we could workaround creating wheels.
    • Here is a preliminary set of wheels on Debian 12 (testing) arm64 https://qtinfo.dev/624_aarch64.tar.gz
    • Maybe the transformation of code within Qt/C++ snippets to a snippet file in Qt/C++ could be a nice task for people wanting to contribute.
      • Then, if the snippet/file exist, we can transform it.
