Right.  When your go() slot is running, that's all that's happening in your program.
 Calls to the @textedit are put into the queue and will update and refresh the next
available opportunity the event loop runs, but that won't happen until you finish
running your slot.

If you need the program to be more responsive, you need to look into using a
Qt::Timer to call a slot repetetively.  That way Qt can go back to handling all of
the events in the event loop in between timer calls.

HTH,
Caleb
