Method: SugarCube::Repl.tree

Defined in:

lib/cocoa/sugarcube-repl/repl.rb

.tree(item = nil, selector = nil, &sel_blk) ⇒ Object

Parameters:

• item (defaults to: nil) —

  this can be a tree-like item (View, ViewController, CALayer, Menu) or an integer, in which case it will select that window. Defalt is to display the keyWindow

• selector (defaults to: nil) —

  If you pass an unsupported object to tree, you will need to pass a selector as well - this method should return an array of items which are passed recursively to tree
