Overview

This observer interface is implemented to react to events on a definitions collection. To implement this observer, create a Ruby class of this type, override the desired methods, and add an instance of the observer to the collection of interest.

Examples:

class MyDefinitionsObserver < Sketchup::DefinitionsObserver
  def onComponentAdded(definitions, definition)
    puts "onComponentAdded: #{definition.name}"
  end
end

Sketchup.active_model.definitions.add_observer(MyDefinitionsObserver.new)
