GObject ╰── AtkObject ╰── AtkSocket
AtkSocket implements AtkComponent.
Together with AtkPlug, AtkSocket provides the ability to embed
accessibles from one process into another in a fashion that is
transparent to assistive technologies. AtkSocket works as the
container of AtkPlug, embedding it using the method
atk_socket_embed(). Any accessible contained in the AtkPlug will
appear to the assistive technologies as being inside the
application that created the AtkSocket.
The communication between a AtkSocket and a AtkPlug is done by
the IPC layer of the accessibility framework, normally implemented
by the D-Bus based implementation of AT-SPI (at-spi2). If that is
the case, at-spi-atk2 is the responsible to implement the abstract
atk_socket_embed(), so an ATK
implementor shouldn't reimplement them. The process that contains
the AtkPlug is responsible to send the ID returned by
atk_plug_id() to the process that contains the AtkSocket, so it
could call the method
atk_socket_embed() in order to embed it.
For the same reasons, an implementor doesn't need to implement
atk_object_ref_accessible_child(). All the logic related to those
functions will be implemented by the IPC layer.
AtkObject * atk_socket_new (

the newly created AtkSocket instance.
void atk_socket_embed (
const gchar *plug_id);
The class item used by this function should be filled in by the IPC
layer (usually at-spi2-atk). The implementor of the AtkSocket
should call this function and pass the id for the plug as returned
atk_plug_get_id(). It is the responsibility of the application
to pass the plug id on to the process implementing the AtkSocket
