Hello
Effectively, mousewheel events are translated in RAWKEY (very strange for a mouse!)
here my include name and constant I use for my ANAIIS stack... (the usb stack for very limited old classic amigas)
#define WHEEL_UP 0x7a
#define WHEEL_DOWN 0x7b
#define WHEEL_LEFT 0x7c
#define WHEEL_RIGHT 0x7d
On OS4.0 it is different, there are IECLASS_MOUSEWHEEL events, but I don't develop under os4... it's another story
:-D
