Thanks for your quick response

I have a problem with starting the thread. start function is in my render() routine in my RenderThread class. I have tried to call render routine from various locations in my code, but all of them resulted in crashing right at the startup of my application.

I even added a timer event slot to my RenderThread class and call it when I construct the object of this class but got the same result, crashing about a second after the startup!
I have no idea why my app crashes like this!
you can see my code down here.

Qt Code: 
  1. private slots:
  2.     void timerEvent(QTimerEvent *event);
