Gets the singleton Gdk::DisplayManager object.
When called for the first time, this function consults the <envar>GDK_BACKEND</envar> environment variable to find out which of the supported GDK backends to use (in case GDK has been compiled with multiple backends).

Gets the default Gdk::Display.
0
if there is no default display. Glib::RefPtr<const Display> Gdk::DisplayManager::get_default_display | ( | ) | const |
Gets the default Gdk::Display.
0
if there is no default display.

0

The default display for GDK.
You rarely need to use properties because there are get_ and set_ methods for almost all of them.
