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.
