According to the documentation here:

     http://www.fxruby.org/doc/api/classes/Fox/FXWindow.html

the message data for a SEL_MOUSEWHEEL message is an FXEvent object. If 
you're getting a 'nil' value for the message data, you must be using a 
very old version of FXRuby (this bug was fixed in FXRuby version 1.0.19).

At any rate, your handler for a SEL_MOUSEWHEEL message from the 
FXGLCanvas should look something like this:

     canvas = FXGLCanvas.new(...)
     canvas.connect(SEL_MOUSEWHEEL) { |sender, sel, evt|
         delta = evt.code/120
     }

The 'code' attribute of the FXEvent instance for SEL_MOUSEWHEEL messages 
should contain some integer value that is a multiple of 120. The code 
may be positive (for spinning "up") or negative (for spinning "down").

Hope this helps,
