Detailed Description

Simple Timer class.

This is a simple wrapper around the TimeEvent, which makes the later usable without having to subclass it every time.

m_timer.setInterval(1000);
m_timer.setCallback(std::bind(&Class::update, this) );
m_timer.start();

Warning

Note that the callback must be available when it is triggered. If your called function is a bound member function and it goes out of scope, when the callback is called you'll most likely have a segfault. So this is best used as a member calling an update function.

Note

You don't have to call TimeManager::registerEvent ever
