Manipulation Blocks

The manipulation methods below make quick work of shifting around slots and inserting new elements.

append() { ... } » self

Adds elements to the end of a slot.

 Shoes.app do
   @slot = stack { para 'Good Morning' }
   timer 3 do
     @slot.append do
       title "Breaking News"
       tagline "Astronauts ",
         "arrested for space shuttle DUI."
     end
   end
 end

The title and tagline elements will be added to the end of the @slot.

after(element) { ... } » self

Adds elements to a specific place in a slot, just after the element which is a child of the slot.

before(element) { ... } » self

Adds elements to a specific place in a slot, just before the element which is a child of the slot.

clear() » self

Empties the slot of any elements, timers and nested slots. This is effectively identical to looping through the contents of the slot and calling each element's remove method.

clear() { ... } » self

The clear method also takes an optional block. The block will be used to replace the contents of the slot.

 Shoes.app do
   @slot = stack { para "Old text" }
   timer 3 do
     @slot.clear { para "Brand new text" }
   end
 end

In this example, the "Old text" paragraph will be cleared out, replaced by the "Brand new text" paragraph.

prepend() { ... } » self

Adds elements to the beginning of a slot.

 Shoes.app do
   @slot = stack { para 'Good Morning' }
   timer 3 do
     @slot.prepend { para "Your car is ready." }
   end
 end

The para element is added to the beginning of the @slot.
