This is what the completed code for the Simple Paste Applet looks like:

require 'plasma_applet'
 
module RubyTest
  class Main < PlasmaScripting::Applet
    def initialize parent
      super parent
    end
 
    def init
      set_minimum_size 150, 150
 
      layout = Qt::GraphicsLinearLayout.new Qt::Vertical, self
      self.layout = layout
      
      # Three items being laid out:
      
      label = Plasma::Label.new self
      label.text = 'This plasmoid will copy the text you enter below to the clipboard.'
      layout.add_item label
      
      line_edit = Plasma::LineEdit.new self
      begin # only possible in Plasma 4.3 and up 
        line_edit.clear_button_shown = true
      rescue
      end
      layout.add_item line_edit
      
      button = Plasma::PushButton.new self
      button.text = 'Copy to clipboard'
      layout.add_item button
      
      # The layout is done now comes the action:
      
      button.connect(SIGNAL(:clicked)) do
        Qt::Application.clipboard.text = line_edit.text
      end
      
      line_edit.connect(SIGNAL(:returnPressed)) do
        Qt::Application.clipboard.text = line_edit.text
      end
    end
    
  end
