Detailed Description

The base object class for the Accessibility Toolkit API.

This class is the primary class for accessibility support via the Accessibility ToolKit (ATK). Objects which are instances of Atk::Object (or instances of Atk::Object-derived types) are queried for properties which relate basic (and generic) properties of a UI component such as name and description. Instances of Atk::Object may also be queried as to whether they implement other ATK interfaces (e.g. Atk::Action, Atk::Component, etc.), as appropriate to the role which a given UI component plays in a user interface.

All UI components in an application which provide useful information or services to the user must provide corresponding Atk::Object instances on request (in GTK+, for instance, usually on a call to Gtk::Widget::get_accessible()), either via ATK support built into the toolkit for the widget class or ancestor class, or in the case of custom widgets, if the inherited Atk::Object implementation is insufficient, via instances of a new Atk::Object subclass.

Constructor & Destructor Documentation

Atk::Object::Object ( Object&&  src)
noexcept
virtual Atk::Object::~Object ( )
virtualnoexcept

Reimplemented from Glib::Object.

Member Function Documentation

bool Atk::Object::add_relationship ( RelationType  relationship,
const Glib::RefPtr< Object >&  target 
)

Adds a relationship of the specified type with the specified target.

Parameters
relationshipThe Atk::RelationType of the relation.
targetThe Atk::Object which is to be the target of the relation.
Returns
true if the relationship is added.
Glib::RefPtr<Atk::Object> Atk::Object::get_accessible_child ( 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.

Parameters
iA int representing the position of the child, starting from 0.
Returns
An Atk::Object representing the specified accessible child of the accessible.
Glib::ustring Atk::Object::get_description ( ) const

Gets the accessible description of the accessible.

Returns
A character string representing the accessible description of the accessible.
int Atk::Object::get_index_in_parent ( )

Gets the 0-based index of this accessible in its parent; returns -1 if the accessible does not have an accessible parent.

Returns
An integer which is the index of the accessible in its parent.
int Atk::Object::get_n_accessible_children ( ) const

Gets the number of accessible children of the accessible.

Returns
An integer representing the number of accessible children of the accessible.

Gets the accessible name of the accessible.

Returns
A character string representing the accessible name of the object.
Glib::RefPtr<Atk::Object> Atk::Object::get_parent ( )

Gets the accessible parent of the accessible.

By default this is the one assigned with 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 set_parent(), and will return it with this method.

If you are only interested on the parent assigned with set_parent(), use peek_parent().

Returns
An Atk::Object representing the accessible parent of the accessible.
Glib::RefPtr<RelationSet> Atk::Object::get_relation_set ( )

Gets the Atk::RelationSet associated with the object.

Returns
An Atk::RelationSet representing the relation set of the object.
Role Atk::Object::get_role ( ) const

Gets the role of the accessible.

Returns
An Atk::Role which is the role of the accessible.
Glib::RefPtr<StateSet> Atk::Object::get_state_set ( )

Gets a reference to the state set of the accessible; the caller must unreference it when it is no longer needed.

Returns
A reference to an Atk::StateSet which is the state set of the accessible.
static GType Atk::Object::get_type ( )

Sets the accessible name of the accessible.

You can't set the name to nullptr. This is reserved for the initial value. In this aspect nullptr is similar to ATK_ROLE_UNKNOWN. If you want to set the name to a empty value you can use "".

Parameters
nameA character string to be set as the accessible name.
void Atk::Object::set_parent ( const Glib::RefPtr< Atk::Object >&  parent)

Sets the accessible parent of the accessible.

parent can be nullptr.

Parameters

Glib::SignalProxy1< void,void** > Atk::Object::signal_active_descendant_changed ( )
Slot Prototype:
void on_my_active_descendant_changed(void** child)

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.

Parameters
childThe newly focused object.
Glib::SignalProxy2< void,guint,gpointer > Atk::Object::signal_children_changed ( )
Slot Prototype:
void on_my_children_changed(guint change_index, gpointer changed_child)

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

Parameters
change_indexThe index of the added or removed child. The value can be -1. This is used if the value is not known by the implementor when the child is added/removed or irrelevant.
changed_childA gpointer to the child AtkObject which was added or removed. If the child was removed, it is possible that it is not available for the implementor. In that case this pointer can be nullptr.
Glib::SignalProxy1< void,bool > Atk::Object::signal_focus_event ( )
Slot Prototype:
void on_my_focus_event(bool focus_in)

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

Deprecated: 2.9.4: Use the Atk::Object::signal_state_change() signal instead.

Parameters
focus_inA boolean value which indicates whether the object gained or lost focus.
Glib::SignalProxy1< void,AtkPropertyValues* > Atk::Object::signal_property_change ( )
Slot Prototype:
void on_my_property_change(AtkPropertyValues* values)

The signal "property-change" is emitted when an object's property value changes. values contains an Atk::PropertyValues 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.

Toolkit implementor note: ATK implementors should use Glib::object_notify() to emit property-changed notifications. Atk::Object::signal_property_changed() is needed by the implementation of atk_add_global_event_listener() because GObject notify doesn't support emission hooks.

Parameters
valuesAn Atk::PropertyValues containing the new value of the property which changed.
Glib::SignalProxy2< void,const Glib::ustring&,bool > Atk::Object::signal_state_change ( )
Slot Prototype:
void on_my_state_change(const Glib::ustring& name, bool state_set)

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

Parameters
nameThe name of the state which has changed.
state_setA boolean which indicates whether the state has been set or unset.
Glib::SignalProxy0< void > Atk::Object::signal_visible_data_changed ( )
Slot Prototype:
void on_my_visible_data_changed()

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