Current work:

  • QML API public for QML libraries
  • Upstream: Better AUTOMOC
  • Thanks to many external contributors
  • Wiki page about internal API

Discussion

  • Enable loading single libraries to speed up Creator Clang parsing : Will consider / Check box in project to not have it parse the entire tree as a workaround -> https://bugreports.qt.io/browse/QTBUG-119720
  • Dependency creep (rebuilding too many files): Most likely touched a file that is in bootstrap build causing rebuild of moc, consider building tools separately
  • QML API CMake/ Design Studio: Still under Discussion, QML modules, CMake vs .qmlproject, Qt for Python
  • CMake Multiconfig issues: Ninja. VSCode/macOS, not supported in Creator
    • Request to make Ninja Multi-Config the default in Qt Creator
  • Distributed builds (Fast build) upstream rejected, out of scope
