Ah fame! It was always my ambition to get my stuff on slashdot when I first 
started Free Software hacking..

Well not all that much - you can do it in QtRuby too. It's just something you 
can't do in C++, and it's a typical ruby idiom I suppose:

calltest = SenderWidget.new(nil, "calltest") { setText 'DCOP Call Test' }

You can pass a chunk of code to the constructor, so you sort of got you're own 
customized constructor that does more than the usual one. Or do it this way 
to pick up the surrounding environment of the thing being constructed:

a = 'DCOP Call Test' 
calltest = SenderWidget.new(nil, "calltest") { |w| w.setText a }
