  39 /* This is a small class which can be used by all ports
  40    to temporarily suspend the busy cursor. Useful in modal
  41    dialogs.
  42
  43    Actually that is not (any longer) quite true..  currently it is
  44    only used in wxGTK Dialog::ShowModal() and now uses static
  45    wxBusyCursor methods that are only implemented for wxGTK so far.
  46    The BusyCursor handling code should probably be implemented in
  47    common code somewhere instead of the separate implementations we
  48    currently have.  Also the name BusyCursorSuspender is a little
  49    misleading since it doesn't actually suspend the BusyCursor, just
  50    masks one that is already showing.
  51    If another call to wxBeginBusyCursor is made while this is active
  52    the Busy Cursor will again be shown.  But at least now it doesn't
  53    interfere with the state of wxIsBusy() -- RL
