File Chooser<sup>2</sup>

²A built in hybrid ruby/java library

Start by loading in the chooser library, the purpose of this library is to allow you to use the vanilla processing interface to the native file chooser (it is almost impossible to use vanilla processing reflection methods without this sort of wrapper)

load_library :chooser

def setup
  java_signature 'void selectInput(String, String)'
  selectInput('Select a file to process:', 'fileSelected')
end

def fileSelected(selection)
  if selection.nil?
    puts 'Window was closed or the user hit cancel.'
  else
    puts format('User selected %s', selection.get_absolute_path)
  end
end
