Well, the FXRuby API documentation for events is about as good as it's 
going to be. Each class lists all of the events that it might send to 
its message target, as well as the message data that's sent along with 
the event. And as Hugh Sasse has pointed out in a separate reply, it is 
/generally/ the case that a widget of some derived class (like 
FXGLCanvas) will also send the messages that its superclass sends.

So for FXGLCanvas, you'd start at its documentation page:

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

Now, as it turns out, FXGLCanvas doesn't add anything, in terms of 
messages sent, to its superclass, so no events are listed here. But if 
you jump up to the documentation for its superclass:

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

you see that FXCanvas forwards the SEL_KEYPRESS, SEL_KEYRELEASE, 
SEL_MOTION and SEL_PAINT messages to its target. Jumping further up the 
inheritance chain to FXCanvas' superclass:

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

Things really get interesting. Since FXWindow is the base class for all 
windows (widgets), most of the core functionality (and its 
documentation) starts here.

Hope this helps,
