  65  *  This class is provided as a container for Inkscape's various
  66  *  dialogs.  This allows Inkscape::Application to treat the various
  67  *  dialogs it invokes, as abstractions.
  68  *
  69  *  DialogManager is essentially a cache of dialogs.  It lets us
  70  *  initialize dialogs lazily - instead of constructing them during
  71  *  application startup, they're constructed the first time they're
  72  *  actually invoked by Inkscape::Application.  The constructed
  73  *  dialog is held here after that, so future invokations of the
  74  *  dialog don't need to get re-constructed each time.  The memory for
  75  *  the dialogs are then reclaimed when the DialogManager is destroyed.
  76  *
  77  *  In addition, DialogManager also serves as a signal manager for
  78  *  dialogs.  It provides a set of signals that can be sent to all
  79  *  dialogs for doing things such as hiding/unhiding them, etc.
  80  *  DialogManager ensures that every dialog it handles will listen
  81  *  to these signals.
