Socket

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 methods atk_plug_get_id() and 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_get_n_accessible_children() and atk_object_ref_accessible_child(). All the logic related to those functions will be implemented by the IPC layer.

Inherited Members

From ObjectAtk

atkObject AtkObject* atkObject;: the main Gtk struct
getObjectAtkStruct AtkObject* getObjectAtkStruct(): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
getType GType getType()
addRelationship bool addRelationship(AtkRelationType relationship, ObjectAtk target): Adds a relationship of the specified type with the specified target.
connectPropertyChangeHandler uint connectPropertyChangeHandler(AtkPropertyChangeHandler* handler)
getAttributes AtkAttributeSet* getAttributes(): Get a list of properties applied to this object as a whole, as an #AtkAttributeSet consisting of name-value pairs. As such these attributes may be considered weakly-typed properties or annotations, as distinct from strongly-typed object data available via other get/set methods. Not all objects have explicit "name-value pair" #AtkAttributeSet properties.
getDescription string getDescription(): Gets the accessible description of the accessible.
getIndexInParent int getIndexInParent(): Gets the 0-based index of this accessible in its parent; returns -1 if the accessible does not have an accessible parent.
getLayer AtkLayer getLayer(): Gets the layer of the accessible.
getMdiZorder int getMdiZorder(): Gets the zorder of the accessible. The value G_MININT will be returned if the layer of the accessible is not ATK_LAYER_MDI.
getNAccessibleChildren int getNAccessibleChildren(): Gets the number of accessible children of the accessible.
getName string getName(): Gets the accessible name of the accessible.
getObjectLocale string getObjectLocale(): Gets a UTF-8 string indicating the POSIX-style LC_MESSAGES locale of @accessible.
getParent ObjectAtk getParent(): Gets the accessible parent of the accessible. By default this is the one assigned with atk_object_set_parent(), but it is assumed that ATK implementors have ways to get the parent of the object without the need of assigning it manually with atk_object_set_parent(), and will return it with this method.
getRole AtkRole getRole(): Gets the role of the accessible.
initialize void initialize(void* data): This function is called when implementing subclasses of #AtkObject. It does initialization required for the new object. It is intended that this function should called only in the ..._new() functions used to create an instance of a subclass of #AtkObject
notifyStateChange void notifyStateChange(AtkState state, bool value): Emits a state-change signal for the specified state.
peekParent ObjectAtk peekParent(): Gets the accessible parent of the accessible, if it has been manually assigned with atk_object_set_parent. Otherwise, this function returns %NULL.
refAccessibleChild ObjectAtk refAccessibleChild(int i): Gets a reference to the specified accessible child of the object. The accessible children are 0-based so the first accessible child is at index 0, the second at index 1 and so on.
refRelationSet RelationSet refRelationSet(): Gets the #AtkRelationSet associated with the object.
refStateSet StateSet refStateSet(): Gets a reference to the state set of the accessible; the caller must unreference it when it is no longer needed.
removePropertyChangeHandler void removePropertyChangeHandler(uint handlerId)
removeRelationship bool removeRelationship(AtkRelationType relationship, ObjectAtk target): Removes a relationship of the specified type with the specified target.
setDescription void setDescription(string description): Sets the accessible description of the accessible. You can't set the description to NULL. This is reserved for the initial value. In this aspect NULL is similar to ATK_ROLE_UNKNOWN. If you want to set the name to a empty value you can use "".
setName void setName(string name): Sets the accessible name of the accessible. You can't set the name to NULL. This is reserved for the initial value. In this aspect NULL is similar to ATK_ROLE_UNKNOWN. If you want to set the name to a empty value you can use "".
setParent void setParent(ObjectAtk parent): Sets the accessible parent of the accessible. @parent can be NULL.
setRole void setRole(AtkRole role): Sets the role of the accessible.
