//! This example implements a basic macOS Calculator clone. It showcases:
|
|
//!
|
|
//! - A single-window app
|
|
//! - Button handling
|
|
//! - Autolayout
|
|
//! - Message dispatching
|
|
//! - Global key/event handling
|
|
//!
|
|
//! It does not attempt to be a good calculator, and does not implement the
|
|
//! extended Calculator view.
