How do I detect mouse wheel scroll events?

[davidWeiZhou]

I did not find the mouse wheel scrolling event, Can anybody help me?

you could

mouse.hook(mouse_handler)

def mouse_handler(event):
    if isinstance(event, mouse.WheelEvent):
        // handle wheel scrolling

you could

mouse.hook(mouse_handler)

def mouse_handler(event):
    if isinstance(event, mouse.WheelEvent):
        // handle wheel scrolling

There isn't a function for the specific event? the hook function is a bit overkill as it grabs all occurred events.
