Implemented Interfaces

TpBaseCallChannel implements TpSvcChannel and TpSvcChannelTypeCall1.

Includes

#include <telepathy-glib/telepathy-glib.h>

Description

This base class makes it easier to write TpSvcChannelTypeCall1 implementations by implementing its properties, and some of its methods.

Subclasses should fill in TpBaseCallChannelClass.accept, TpBaseCallChannelClass.add_content and TpBaseCallChannelClass.hangup virtual function.

Functions

TpBaseCallChannelVoidFunc ()
