Mario's already given you a good answer, but just as a general hint in 
reading the wxRuby docs: - in the argument list, the grey capitalised 
first part of each argument (eg "Icon") is the ruby class of the object 
that's expected. So if it's "Icon", it wants a Wx::Icon, if it's 
"String" it wants a ruby String.

Wow, cool, I never knew that wxRuby handled SVG icons. I expect this is 
GTK only though..

it's a bit confusing - "argument 2" here means the first argument to 
ruby - this is a SWIG idiocy that it reports errors from a C++ 
perspective...

Though the class reference docs are pretty comprehensive, I know they're 
not always that helpful getting an overall idea of how to use a class. 
There is an excellent book on wxWidgets programming which used to be 
available as a free PDF. Although the examples are in C++, it's got lots 
and lots of ideas and detailed discussion of how the wxRuby classes work.
