@get
Description:
Gets the singleton DisplayManager object.
When called for the first time, this function consults the `GDK_BACKEND` environment variable to find out which of the supported GDK backends to use (in case GDK has been compiled with multiple backends). Applications can use set_allowed_backends to limit what backends can be used.
Returns:
|
The global DisplayManager singleton; parse_args, init, or init_check must have been called first. |
