QTimer or recursive calls for simulation?

[Morea]

Great!
I would really like it to draw at maximum speed without any pauses (even if they are really short) and I wish to avoid any problem if it timeout before drawing and calculations are done.
Is there a non-crashing solution to this other than to generate all data and then animate it afterwards?

Use a singleshot QTimer with 0 timeout time. It will trigger instantly when all previous events are handled.

void MyClass::myTimeoutSlot(){
  doSomething();
  update();
  QTimer::singleShot(0, this, SLOT(myTimeoutSlot()));
}

void MyClass::myTimeoutSlot(){
  doSomething();
  update();
  QTimer::singleShot(0, this, SLOT(myTimeoutSlot()));
}
