Overview

This class is abstract.

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.

This observer interface is implemented to react to events on a definitions collection.

Examples:

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

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

end
