[Gambas-user] Can I use the mousewheel to control system audio volume?

[Marc Carson]

I would like to create a program that increments/decrements the system 
master audio volume if the mouse's mousewheel is scrolled up/down, in 
combination with a hotkey (like ctrl+shift+mousewheel).

Is this possible in Gambas? I see that the mousewheel can be detected, 
but I don't see anything about up or down. I also see volume-related 
items in SDL but I'm not sure if this is necessary to use or if there's 
some better component for the task.

Thank you,

Marc
