QObject::connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater())) QObject::connect(worker, SIGNAL(finished()), worker, SLOT(deleteLater())) QObject::connect(worker, SIGNAL(finished()), thread, SLOT(quit())) QObject::connect(setbutton, SIGNAL(clicked()), worker, SLOT(setVariable())) QObject::connect(thread, SIGNAL(started()), worker, SLOT(process()))

Window->setLayout(layout) QThread* thread = new QThread But now I want to post another question.Only for test I implemented this You example was very clear and helpful for me. W.show() qDebug() << 'Main Thread:' << QThread::currentThreadId()

QPushButton *stop=new QPushButton('Stop', this) Ĭonnect(stop, SIGNAL(clicked()), sensor, QPushButton *start=new QPushButton('Start', this) Ĭonnect(start, SIGNAL(clicked()), sensor, SLOT(start())) Sensor=new Sensor(this) QVBoxLayout *l=new QVBoxLayout(this) Second, I've found that creating a class which manages both the thread and the worker as well as providing an interface to the rest of the application makes this far easier to understand and maintain. QObject::connect(button, SIGNAL(clicked()), &s1, SLOT(ExecSlot())) įirst off, if you read the 'Notes' section of the 'QThread': docs you will find two excellent examples of how threading should be done with Qt (written, in fact, by Andre o). QApplication a(argc, argv) qDebug() addWidget(button) Private slots: // private slots gonna make ExecSlot() calling only from QObject::connect * but you have to read about signals and slots * Sub Classing QThread isn't a save way I can't explain the reasons right now * if you allocated in dynamic memory using malloc or new. * so you gonna need to delete Sensor after you done * QObject::moveToThread: Cannot move objects with a parent I typed a simple code for you to able understand what you gonna do Or you forget to put your class in separate file with define lock outside main file If you forget to implement it into your subclass

This error mean one of two reasons you don't have execslot() in your subclass Q_OBJECT macro isn't working and its happened only QObject::connect: No such slot QThread::execslot(). Thanks Andre, He said what I wanna trying to say anyway
