Using QTimer in QThreads

[tzhu]

Hi, I just started learning Qt several days ago, and I got stuck on this for a while now. I'm trying to create a new thread in which a QTimer would run, and connect the timer's timeout() signal to a function running in that thread. Here is one of the things that I tried:

I try to run a timer here connected to a slot in MyObject (onTimeOut)


class MyThread : public QThread
{
public:
MyThread();
~MyThread();

QTimer *timer;
void run();
};

void MyThread::run()
{
MyObject object;
timer = new QTimer;
connect(timer, SIGNAL(timeout()), &object, SLOT(onTimeOut()));
timer->start(500);
exec();
}

To my understanding this should call onTimeOut every half second, but that's not happening. Is there something that I'm missing completely?

Hi,

Does "MyObject" class inherit from QObject and has declared the macro "Q_OBJECT" ?
What is returning the "connect" statment? just add a boolean value as return value and also check the console output.

Doh I did forget Q_OBJECT in MyObject! Now I'm embarassed to have wasted 2 hours on that... :o
