how to create a main.moc file??

[spirit]

you need to create object deriven from QObject and then regenerate project, i.e. call qmake.

hi,

could u please provide me with an example??

Thanks

[spirit]

yesterday example :D


#include <QTimer>
#include <QApplication>

class MyProcessEventDispatcher: public QObject
{
Q_OBJECT

public:
MyProcessEventDispatcher(QObject *parent = 0)
: QObject (parent)
{
connect(&m_timer, SIGNAL(timeout()), SLOT(updateEvents()));
m_timer.setInterval(100);
m_timer.start();
}

private slots:
void updateEvents()
{
m_timer.start();
qApp->processEvents();
}

private:
QTimer m_timer;
};
#include "main.moc"
int main(int argc, char **argv)
{
QApplication app(argc, argv);
MyProcessEventDispatcher mpee;
//...
return app.exec();
}

add this code to yours main.cpp, clean your project and then call qmake. now, when you start compilation main.com will be generated.

// main.cpp

class Object : public QObject
{
// no Q_OBJECT macro here
};

int main()
{
}

#include "main.moc" // moc file included by hand, but there is nothing for moc to generate


vs.



// main.cpp

class Object : public QObject
{
Q_OBJECT // macro exists
};

int main()
{
}

#include "main.moc" // moc file included by hand, moc generates meta object code for "Object"

hi guys,

thanks for clearing that up..i have another query..i m trying smth like this from main.cpp


QTimer timer;
bool isConnect = QObject::connect(&timer, SIGNAL(timeout()), qApp, SLOT(processEvents()));
timer.start(100);

now this, wont connect cuz processEvents() isnt actually a slot..is there any possible way i can call qApp->processEvents() from main.cpp on timeout of a timer..it would be great help if u can help me solve this..

thanks in advance!

I've posted an example how to do this. why you can't use it? it solves you problem. :)

buddy, i tried that..in ur case, updateEvents() was called only once..no more than that..so i just wanted to try this as the last option..or i'll just give this problem to sm1 else..

in your case (which you try to achive) you will have the same behavior, because yours "have"-comp block event loop! so, there is no difference between your code (what you try to achive) and my!
