[Qt-interest] Slots in threads ?

[Patric]

Hi Will, 
this approach to use directly the QThread is interesting. I have used the method with moveToThread() with derived one. 

Anyway, I think in my case I can do it the way it's done in the Mandelbrot example. There is a forever loop in run(), at the end of which condition.wait() is called. And when we want to wake it, we just call some method in our derived thread which wakes it. :) 

In my case I need the process to be interrupted at any time, so I think this will be the better way. 

Regards

  The way I normally do it is to have a worker object (with class derived from QObject) and call the object's moveToThread() to attach it to your thread.  You do not subclass QThread but use it directly, then call its start().  This will run its event loop by default.  You connect slots in the worker object to the appropriate signals.  Then when those signals are emitted the object will do its work within the thread.

    Hello, 
    I have a little gui program with one worker thread. I want to stop and start the thread from the gui. So I put some slots inside the thread. But now I'm getting some errors on compilation : 


    mainwindow.cpp: In constructor `MainWindow::MainWindow(QWidget*)': 
    mainwindow.cpp:35: error: no matching function for call to `MainWindow::connect(Board*&, const char*, Engine*, const char*)'

    c:/Qt/2009.03/qt/include/QtCore/../../src/corelib/kernel/qobject.h:202: note: candidates are: static bool QObject::connect(const QObject*, const char*, const QObject*, const char*, Qt::ConnectionType)

    c:/Qt/2009.03/qt/include/QtCore/../../src/corelib/kernel/qobject.h:308: note: bool QObject::connect(const QObject*, const char*, const char*, Qt::ConnectionType) const



    Am I allowed to put slots in threads ? 

    Regards
