 /*
   Kcalc basically consist of a class for the GUI (here), a class for
   the display (dlabel.h), and one for the mathematics core
   (kcalc_core.h).
 
   When for example '+' is pressed, one sends the contents of the
   Display and the '+' to the core via "core.Plus(DISPLAY_AMOUNT)".
   This only updates the core. To bring the changes to the display,
   use afterwards "UpdateDisplay(true)".
 
   "UpdateDisplay(true)" means that the amount to be displayed should
   be taken from the core (get the result of some operation that was
   performed), "UpdateDisplay(false)" has already the information, what
   to be display (e.g. user is typing in a number).  Note that in the
   last case the core does not know the number typed in until some
   operation button is pressed, e.g. "core.Plus(display_number)".
