86 * UI::Dialog::Dialog is a base class for all dialogs in Inkscape. The
87 * purpose of this class is to provide a unified place for ensuring
88 * style and behavior. Specifically, this class provides functionality
89 * for saving and restoring the size and position of dialogs (through
90 * the user's preferences file).
91 *
92 * It also provides some general purpose signal handlers for things like
93 * showing and hiding all dialogs.
