Implemented Interfaces

AgsApplicationContext implements AgsConnectable.

Includes

#include <ags/object/ags_application_context.h>

Description

AgsApplicationContext is a context provider is your and libraries entry point to the application. You might subtype it to implement your own contices. Thus you should consider to create a provider interface for reusability.
