Method: Teacup::Layout#auto

Defined in:
lib/teacup/layout.rb

#auto(layout_view = top_level_view, layout_subviews = {}, &layout_block) ⇒ Object

Calling this method uses Nick Quaranto’s motion-layout gem to provide ASCII art style access to autolayout. It assigns all the subviews by stylename, and assigns self.view as the target view. Beyond that, it’s up to you to implement the layout methods:

auto do
  metrics 'margin' => 20
  vertical "|-[top]-margin-[bottom]-|"
  horizontal "|-margin-[top]-margin-|"
  horizontal "|-margin-[bottom]-margin-|"
end
