Hello,

Is it possible  to detect if mousewheel has been moved up or down in real time ?

thanks

What do you mean with "real time"?

You can use sf::Event::MouseWheelScrolled (not sf::Event::MouseWheelMoved). Is the latency for event handling really too high?

What is the difference between sf::Event::MouseWheelScrolled and  sf::Event::MouseWheelMoved ?

By real time I mean outside the pollevent loop, like for example sf::Keyboard::isKeyPressed I can use it everywhere.

But I think my question is stupid because this seems impossible, sorry..

The latter is deprecated, don't use it anymore.

This is conceptually impossible because real-time input is used to query the current state, and the scroll wheel has none. The event notifies you about a change (hence delta as a difference), not the current state.
