Now Im just trying to get the syntax right for those inner args arrays. eg(not working)

It does you no good to construct an object without a reference to it (the line with Hash.new).
If you want to use a Hash, then use one for your Widgets. They need not be a custom subclass, unless you need custom methods. Hashes dont need attributes (instance refs,) because they use key / value pairs, instead.
my_widget_1 = {
'xPos' => 3.4,
'yPos' => 1.0,
'zPos' => 2.3,
'height' => 6.784,
'width' => 4.0,
'type' => "some_type"
}
There is another thread on how to save and retrieve hashes into/from an Attribute dictionary.

Arguments: *list_name compacts an argument list into a local array referenced by list_name
Within the method, you can access array elements using the [] method.
def some_method(*args)
@xPos =( args.size>0 ? args[0] ; 0.0 )
@yPos =( args.size>1 ? args[1] ; 0.0 )
# etc.
end
If you use 5 arguments, but a call gives more than 5, the addtional arguments will be still be stored in the local array, and no ArgumentError, will be raised.
I suggest you visit the Code Snippet index:
