[Qt-interest] QGraphicsScene problem

[Patric]

And something else, the QGraphicsScene instance is put through the constructor of the thread, so actually the thread is accessing the scene which lives in the main thread.

  Hello guys, 
  I have QGraphicsScene here with items on it. 

  I have manual control (i.e. keyboard events) and also auto control (through a thread which makes all the calculations where these QPixmapItems should interact). 

  When I control them, everything is OK. 
  But when I start the auto control, i.e. my thread which simulates the actions, I'm observing a very strange behaviour. It's a game actually, it's turn based. 
  So somethimes the objects on the board are just not moving on their turns. 

  I have implemented this simulation engine with the technique used in the Mandelbrot example. 

  In my MainWindow class I have instance of the engine thread, and when some button in the GUI is pressed MainWindow calls a method in the thread (directly), which wakes the thread. 
  And I'm getting this shit : 

  QObject::killTimer: timers cannot be stopped from another thread 
  QObject::startTimer: timers cannot be started from another thread

  QObject::killTimer: timers cannot be stopped from another thread

  QObject::startTimer: timers cannot be started from another thread

  QObject::killTimer: timers cannot be stopped from another thread

  QObject::startTimer: timers cannot be started from another thread



  Any ideas why ? 



  Regards,

  p.s.:in the end of the thread's run method there is sleep call also.
