-- The purpose of the t'GI.Gdk.Objects.DisplayManager.DisplayManager' singleton object is to offer
-- notification when displays appear or disappear or the default display
-- changes.
-- 
-- You can use 'GI.Gdk.Objects.DisplayManager.displayManagerGet' to obtain the t'GI.Gdk.Objects.DisplayManager.DisplayManager'
-- singleton, but that should be rarely necessary. Typically, initializing
-- GTK+ opens a display that you can work with without ever accessing the
-- t'GI.Gdk.Objects.DisplayManager.DisplayManager'.
-- 
-- The GDK library can be built with support for multiple backends.
-- The t'GI.Gdk.Objects.DisplayManager.DisplayManager' object determines which backend is used
-- at runtime.
-- 
-- When writing backend-specific code that is supposed to work with
-- multiple GDK backends, you have to consider both compile time and
-- runtime. At compile time, use the @/GDK_WINDOWING_X11/@, @/GDK_WINDOWING_WIN32/@
-- macros, etc. to find out which backends are present in the GDK library
-- you are building your application against. At runtime, use type-check
-- macros like @/GDK_IS_X11_DISPLAY()/@ to find out which backend is in use:
-- 
-- ## Backend-specific code ## {@/backend/@-specific}
