Thanks for the information. The reason I run into this issue is that I'm using 
rspec to write unit tests for my application and, given that they should run 
without human intervention, I don't want the event loop to start. However, 
right now this is not a great problem for me, since this was the only test 
which gave me trouble.

As for how to trap the exit of the script, I tried putting the line you 
suggested in a block passed to at_exit and add it to the example script I 
posted in my first mail, like this:

require 'korundum4'

class Dlg < KDE::PageDialog
  
  define_method(:add_page){puts "ADDED"}
  private :add_page
  
  def test_private
  end
  
  private :test_private
  
end

at_exit{Qt::Internal.application_terminated = true}

data = KDE::AboutData.new "test", "", KDE::ki18n("test"), "0.0.1"
KDE::CmdLineArgs.init [], data
app = KDE::Application.new
dlg = Dlg.new
w = Qt::Label.new "TEST"
it = KDE::PageWidgetItem.new w
dlg.add_page it
puts "created"

It worked correctly in this simple case, but I don't know whether it would 
work in more complex cases and whether it would have unwanted side effects.
