Image Clearing

The clear command should delete everything in the slot. There have been improvements in Shoes 3 for managing the image cache That may help. You could file an issue with Shoes 3

Ah ok so it's an image cache issue? When I followed the advice a friend, that mentioned recreating the buttons every time you clear the screen:

Shoes.app do
  
  def clear_screen
    clear
  end
  
  def generate_poem
    system("ruby QRPoetry.rb")
  end
  
  # In this one, I can't seem to read the image unless it's in the main directory.
  def display_image
    image "poem.png"
  end
  
  def display_button
    button("Generate Poem") {
      c = clear_screen; i = image_clear; g = generate_poem; d = display_button; d = display_image
    }
    
    button("Exit") {
      exit
    }
  end
  
  flow do
    button("Generate Poem") {
      c = clear_screen; g = generate_poem; d = display_button; d = display_image
    }
    
    button("Exit") {
      exit
    }
  end
  
end

The system call refers to an external script that generates a QR code from a Ruby Gem, and I have the Shoes app display the image generated from the external script.
