class Layout::Block

• Layout::Block
• Reference
• Object

Overview

A 2-dimensional region within the layout. You can constrain the different Primitives on a block in order to properly position it.

Example

The follow will create a 100x100 square that is offset from the top left corner of the screen by half it's width.

region = Block.new
region.height.eq 100
region.width.eq 100
region.top.eq region.width / 2
region.left.eq region.width / 2
