Poco Timer with callback from same class

I have a simple class which uses Poco Timer:

MyClass::MyClass(){
 Timer timer(250,5000);
 TimerCallback<MyClass> callback(*this, &MyClass::onTimer);
 timer.start(callback);
}

MyClass::onTimer(){
  cout <<"Tick"<<endl;
}

Obviously, the code for callback initialization is incorrect. What is the correct way to call a function from within the same class (this) with TimerCallback?

You can use Timer as member of MyClass:

MyClass {
  //...
  Timer timer;
};

then construct timer object on initialization list to set intervals in ctor of Timer

MyClass::MyClass() : timer(250,5000) { // <--
  TimerCallback<MyClass> callback(*this, &MyClass::onTimer);
  timer.start(callback);
}

or use setPeriodicInterval and setStartInterval

  MyClass::MyClass() {
   timer.setStartInterval(500);
   timer.setPeriodicInterval(2500);
   TimerCallback<MyClass> callback(*this, &MyClass::onTimer);
   timer.start(callback);
  }
