Why This Course?

Make your Qt C++ apps faster, responsive and reliable using threads and IPC

Learn By Doing — Practical Examples

  • Create and manage threads the right way in Qt
  • Use thread pools and Qt Concurrent for scalable background work
  • Design thread-safe components and avoid common concurrency bugs

Why This Matters: Generic threading tutorials miss Qt-specific patterns. This course focuses on Qt idioms and best practices.

Qt Concurrency & IPC

  • Qt Concurrent, QThread, QThreadPool, and worker objects
  • Inter-process communication including QProcess and DBus integration
  • Synchronization primitives, signals/slots across threads, and reentrancy

Why This Matters: Platform-specific threading APIs are fragmented. Qt gives a unified, cross-platform approach.

Learn From Real Examples

  • Hands-on demos you can run and extend in minutes
  • Code patterns that translate to production systems
  • Guidance on debugging and profiling multithreaded apps

Why This Matters: Debugging multi-threaded code without examples is slow; we provide working demos and tips.
