You are using sleep in your thread (the main thread called QApplication:), how 
do you expect Qt's events for signals/slots and (more important) screen redraw 
to work when the thread is sleeping?

The solution is to use a slot that sets the text and do an delayed execution 
with QTimer::singleShot( X * 1000, <object_of_the_slot>, SLOT( 
<slot_signature> ) );

Have fun,

Arnold
