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.

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()

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 "".
