WARNING: Cushy is in early alpha. This guide doubly so.


The Canvas widget invokes a function each time it needs to paint. This function has access to a graphics context exposing most of Kludine's 2D graphics API.

A Tick can be attached to the Canvas to have a callback invoked at a steady rate. This tick function can be used to update the state of the Canvas, and it can signal when the Canvas should be redrawn.
