I want to either increment or decrement a variable based on which way the mousewheel is turned. Right now, I catch an EVT_MOUSEWHEEL event and in my OnMousewheel function I check the sign of event.GetWheelRotation to determine if I will increment or decrement my variable.
That, however, doesn't seem to work. So, does anyone know if that is the correct way of handling a mousewheel event for my purposes? Because if it is I'll at least know the problem is elsewhere.
