Class: Shoes::Shape

Inherits:
Slot show all
Defined in:
lacci/lib/shoes/drawables/shape.rb

Overview

A Shape acts as a sort of union type for drawn shapes. In Shoes you can use it to merge multiple ovals, arcs, stars, etc. into a single drawn shape.

In Shoes3, a Shape isn't really a Slot. It's a kind of DSL with drawing commands that happen to have the same name as the Art drawables like star, arc, etc. Here we're treating it as a slot containing those drawables, which is wrong but not too wrong.

Incompatibilities with Shoes:

  • A Shoes3 Shape is not a slot; Scarpe does not do union shapes
