//! The root view controller for our Todos window. All we do here is attach our ListView and pass
|
|
//! messages downwards. You could theoretically remove this layer of indirection, but a more
|
|
//! complicated app probably wouldn't, and I figure it's worth having this here for those who might
|
|
//! use this example as a jumping-off point.
