BtApplication: Buzztrax Bt-Core Reference Manual

## BtApplication BtApplication — base class for a buzztrax based application |

## Properties

GstBin * | bin | Read
BtSettings * | settings | Read

## Types and Values

## Object Hierarchy

## Includes

    #include <libbtcore/core.h>

## Description

Every application using the libbtcore library should inherit from this class. Implementations should implement the singleton pattern.

The base class automatically creates a GstBin element as a container for the song. This can be retrieved via the “bin” property. When creating BtSong instances, the BtApplication instance needs to be passed to the `bt_song_new()` constructor, so that it can retrieve the GstBin element.

Another module the application base class maintains is a settings instance (see BtSettings), that manages application preferences.
