QTimer and QThread

[Poter]

Hello,
I think You can improve your run() function in the following way:

void Logger::run()
{   
   QTimer timer;
   timer.setInterval(updateIntervalSeconds*1000);  
   connect(&timer, SIGNAL(timeout()), this, SLOT(doJob()));  
 
   timer.start();  
 
   exec();   
}

void Logger::run()
{   
   QTimer timer;
   timer.setInterval(updateIntervalSeconds*1000);  
   connect(&timer, SIGNAL(timeout()), this, SLOT(doJob()));  

   timer.start();  

   exec();   
}

To copy to clipboard, switch view to plain text mode 

I think it is better to create QTimer object on the stack. This object will be destroyed automatically when the run() function finishes. When You call exec() - evet loop is started at this point.

ok,
I've see that the doJob() function is executed in main (gui) thread. Have I set up my timer incorrectly?
By the way, I need the job executed every second or so, and I just wanted to use a timer instead of having a while loop with a sleep().

how do I get the timer firing so that doJob() runs in the new thread?

thanks

Try:

connect( &timer, SIGNAL( timeout() ), this, SLOT( doJob() ), Qt::DirectConnection );

connect( &timer, SIGNAL( timeout() ), this, SLOT( doJob() ), Qt::DirectConnection );

To copy to clipboard, switch view to plain text mode 

or move doJob() to another class that you will instantiate in run(), since the Logger instance itself lives in the GUI thread.
