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 objects of interests.

This observer interface is implemented to react to pages events.

Examples:

# This is an example of an observer that watches the pages for new ones.
class MyPagesObserver < Sketchup::PagesObserver
  def onElementAdded(pages, page)
    puts "onElementAdded: #{page}"
  end
end

# Attach the observer.
Sketchup.active_model.pages.add_observer(MyPagesObserver.new)

Version:
