    Default Designing Multithreaded app in Qt

    I want to create multi-threaded application in Qt (GUI).

    Thread 1: Take account of all the logging.
    Thread 2: Some math calculations(worker thread).
    Thread 3: GUI

    u cant do GUI in QThreads .. QWidget is not reentrant ... so thread3 is invalid ..

    use the gui as main event loop .. from there spawn two thread
    thread1: loggings (only text, image, QTimers .,..)
    thread2: calculation algorithms ..

    best example if u are newbie to QThread is
    /examples/network/blockingfortuneclient
    because for me it looks very easy to ride the concept ..

    You can do 1. and 3. in the same thread. For 2. you can (but don't have to) use an external thread.

    Read the article in QQ: http://doc.trolltech.com/qq/qq27-responsive-guis.html
