2.3.18: 2006-03-25 Murray Cumming * bakery/Utilities/BusyCursor.cc: Destructor: Do not force a gui update if the Gdk::Window was null. This avoid an invalid uninstantiatable type warning, though I am not sure why. 2006-03-25 Murray Cumming * bakery/Utilities/BusyCursor.cc: Do not use the Gdk::Window if it is null. 2006-04-25 Murray Cumming * bakery/Utilities/BusyCursor.h: Adde a constructor that takes a window pointer, as well as the existing constructor that takes a reference, so that application code does not need to test for a null parent window and thus lose the advantage of scope lifetime.
