Hi,
I also started with the global $app variable from the tank example,
but needed some much much more cleaner way -- my code being an
educational piece.
Of course, for "standard GUI" elements like the popup menu example
Krzysztof posted -- that's prime example for the inheritance solution.
I didn't like to go the inheritance way in a simple game I did
recently ("favor composition over inheritance" etc), so I came up with
wrapping the Shoes object in a Canvas class:
-->
http://github.com/karmi/sheep_in_your_shoes/tree/master/sheep_in_your_shoes.rb#L21-30
This way I can then write things like `Canvas.get.width` or
`Canvas.draw { oval 0, 0, 15, 15 }`.
I set the reference to canvas in the beginning of the `Shoes.app
do ... end` block:
-->
http://github.com/karmi/sheep_in_your_shoes/tree/master/sheep_in_your_shoes.rb#L191
So the different responsibility is separated into different classes.
I'd be interested to know what you think about this approach.

Try designing your external files as modules, too, that get included
into your Shoes.app block.
See:

And check out some of the apps in the shoebox.

I did something similar to what you are describing without making a
widget.
I was storing the Shoes objects in class attributes of an outside
class, but
did all the creating and storing of these objects from within the
Shoes.app
block. For my application this was a pretty clean approach. If this
would be
messy for yours, then perhaps a widget is the way to go.

How do
you use shoes elements in your classes outside of the main
Shoes.app file?
I'm so very confused. Halp!
Thanks!
