sample rbcurse app inside a class (using App class)

testapp2.rb

require 'rbcurse/app'

####
#  If you want to create an application which can run standalone from terminal, or be passed
#  values from a previous form then this is one way you can do it.
#
# this was a test to see how i could have a class and an app inside
# and i could call methods in the class and have variables available
# inside App.
#
# instance_eval inside stack and others was causing the issue putting everything in
# App. However, i have to change the app, to use yield in order not to lose context

class Testy
  attr_accessor :value
  def initialize val
    @value = val
    @my = "oldval"
    run
  end
  # i will call this method from within the App block
  def amethod
    $log.debug "XXXX amethod called... " if $log.debug? 
    #alert " self #{self.class} amethod "
    # we will access @my from insdie the block, we also access @f from here
    @my = "hellothere #{@f.getvalue} "
  end
  def run

    App.new do |app|
      $log.debug " APP : value #{value}" if $log.debug?

      app.message "Press F1 to exit from here #{@value} "
