Re: Mousewheel scrolling?[SDL 2.03]

The mouse wheel even has the up and down information. If you have a event
receiver function and an update function. Trough the event function you can
get if the mouse moved up or down and the update function you can get the
last wheel state and reset it. In this way you can get the direction for
every loop. If the wheel move faster you will be able to get a value
different than 0 in more loops.

Take a look to this tutorial, may be helpful.
