AtkSocket

Description [src] 

class Atk.Socket : Atk.Object
  implements Atk.Component {
  /* No available fields */
}

Container for AtkPlug objects from other processes

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.

Methods inherited from AtkComponent (16)
atk_component_add_focus_handler

Add the specified handler to the set of functions to be called when this object receives focus events (in or out). If the handler is already added it is not added again.

deprecated: 2.9.4 

atk_component_contains

Checks whether the specified point is within the extent of the component.

atk_component_get_alpha

Returns the alpha value (i.e. the opacity) for this component, on a scale from 0 (fully transparent) to 1.0 (fully opaque).

since: 1.12

atk_component_get_extents

Gets the rectangle which gives the extent of the component.

atk_component_get_layer

Gets the layer of the component.

atk_component_get_mdi_zorder

Gets the zorder of the component. The value G_MININT will be returned if the layer of the component is not ATK_LAYER_MDI or ATK_LAYER_WINDOW.

atk_component_get_position

Gets the position of component in the form of a point specifying component‘s top-left corner.

deprecated: Unknown 

atk_component_get_size

Gets the size of the component in terms of width and height.

deprecated: Unknown 

atk_component_grab_focus

Grabs focus for this component.

atk_component_ref_accessible_at_point

Gets a reference to the accessible child, if one exists, at the coordinate point specified by x and y.

atk_component_remove_focus_handler

Remove the handler specified by handler_id from the list of functions to be executed when this object receives focus events (in or out).

deprecated: 2.9.4 

atk_component_scroll_to

Makes component visible on the screen by scrolling all necessary parents.

since: 2.30

atk_component_scroll_to_point

Move the top-left of component to a given position of the screen by scrolling all necessary parents.

since: 2.30

atk_component_set_extents

Sets the extents of component.

atk_component_set_position

Sets the position of component.

atk_component_set_size

Set the size of the component in terms of width and height.

Signals

Signals inherited from AtkObject (9)
AtkObject::active-descendant-changed

The “active-descendant-changed” signal is emitted by an object which has the state ATK_STATE_MANAGES_DESCENDANTS when the focus object in the object changes. For instance, a table will emit the signal when the cell in the table which has focus changes.

AtkObject::announcement

The “announcement” signal can be emitted to pass an announcement on to be read by a screen reader.

since: 2.46

AtkObject::attribute-changed

The “attribute-changed” signal should be emitted when one of an object’s attributes changes.

since: 2.52

AtkObject::children-changed

The signal “children-changed” is emitted when a child is added or removed from an object. It supports two details: “add” and “remove”.

AtkObject::focus-event

The signal “focus-event” is emitted when an object gained or lost focus.

deprecated: 2.9.4 

AtkObject::notification

The “notification” signal can be emitted to pass an announcement on to be read by a screen reader.

since: 2.50

AtkObject::property-change

The signal “property-change” is emitted when an object’s property value changes. arg1 contains an AtkPropertyValues with the name and the new value of the property whose value has changed. Note that, as with GObject notify, getting this signal does not guarantee that the value of the property has actually changed; it may also be emitted when the setter of the property is called to reinstate the previous value.

AtkObject::state-change

The “state-change” signal is emitted when an object’s state changes. The detail value identifies the state type which has changed.

AtkObject::visible-data-changed

The “visible-data-changed” signal is emitted when the visual appearance of the object changed.

Signals inherited from GObject (1)
GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Signals inherited from AtkComponent (1)
AtkComponent::bounds-changed

The ‘bounds-changed” signal is emitted when the position or size of the component changes.
