PeerHood Qt

What Qt gives to PeerHood


  • Porting possibilities, especially Symbian S60
  • Language mapping via Qt systems, C, Python, Java, ..
  • More rich development base for PeerHood services by additional (to C++ standard library) C++ libraries, like Database (eg. sqlite), GUI (of course), XML libraries (for web usage), ..
  • Common basic functionalities not in C++ standard library: file management, configuration, ..
  • GUI Driven Service (middleware) Develoment ?


Rewrite PeerHood by Qt


  • Improve development of the PeerHood for Research (and Industrial) use.
  • Give a development framework for PeerHood. C++ needs a framework for development and on Comlab we do not have resources neither motivation to make one. QT might be the best convention framework for C++ (compared to C++std boost extension, symbian, MS C++ foundation, ..).
  • Apply Qt conventions: build system, singal-slot system, .. .
  • Support UMSIC project, but not limited to it.


  • Reactor-ThreadPool work applied with Qt main loop and with DBUS main loop.
  • Applying Qt for communications service middleware system. For example is Qt too GUI oriented ?

Research goals

  • Comparison of Plain C++ PeerHood to Qt PeerHood
    • Easy to maintain
    • In feasibility to create services
    • Easy to learn to use (PeerHood Has been hard ?)
    • Performance
    • ..

UMSIC as main user of PeerHood at the moment


  • As Plain PeerHood and Qt PeerHood are both C++ then maybe not complete rewrite is needed, but code can be move on some parts to new implementation.
  • This created dependences to Qt libraries and as well coding usage to Qt. Exposes Qt to UMSIC as well.

Configuration (Control) Manager GUI

  • Very much needed

Activity Monitor GUI

  • Logging
  • syslog, user log, development (debug) log management. Provided by Qt ?
