Detailed Description

Accessible interface.

Gtk::Accessible provides an interface for describing a UI element, like a Gtk::Widget, in a way that can be consumed by Assistive Technologies, or “AT”. Every accessible implementation has:

a “role”, represented by a value of the Gtk::Accessible::Role enumeration
an “attribute”, represented by a set of Gtk::Accessible::State, Gtk::Accessible::Property and Gtk::Accessible::Relation values

The role cannot be changed after instantiating a Gtk::Accessible implementation.

The attributes are updated every time a UI element's state changes in a way that should be reflected by assistive technologies. For instance, if a Gtk::Widget visibility changes, the Gtk::Accessible::State::HIDDEN state will also change to reflect Gtk::Widget::property_visible().

Since gtkmm 3.98:

◆ get_accessible_role()

Role Gtk::Accessible::get_accessible_role ( ) const

Retrieves the Gtk::Accessible::Role for the given Gtk::Accessible.

Returns: A Gtk::Accessible::Role.

◆ get_type()

noexcept

◆ property_accessible_role() [1/2]

Glib::PropertyProxy< Role > Gtk::Accessible::property_accessible_role ( )

The accessible role of the given Gtk::Accessible implementation.

The accessible role cannot be changed once set.

Default value: Gtk::Accessible::Role::NONE

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_accessible_role() [2/2]

Glib::PropertyProxy_ReadOnly< Role > Gtk::Accessible::property_accessible_role ( ) const

The accessible role of the given Gtk::Accessible implementation.

The accessible role cannot be changed once set.

Default value: Gtk::Accessible::Role::NONE

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ reset_property()

void Gtk::Accessible::reset_property ( Property property )

Resets the accessible property to its default value.

Parameters

property A Gtk::Accessible::Property.

◆ reset_relation()

void Gtk::Accessible::reset_relation ( Relation relation )

Resets the accessible relation to its default value.

Parameters

relation A Gtk::Accessible::Relation.

◆ reset_state()

void Gtk::Accessible::reset_state ( State state )

Resets the accessible state to its default value.

Parameters

state A Gtk::Accessible::State.

◆ update_property()

void Gtk::Accessible::update_property	(	Property	property,
		const Glib::ValueBase &	value
	)

Updates an accessible property.

This function should be called by Gtk::Widget types whenever an accessible property change must be communicated to assistive technologies.

Parameters

property	A Gtk::Accessible::Property.
value	A Glib::ValueBase.

◆ update_relation()

void Gtk::Accessible::update_relation	(	Relation	relation,
		const Glib::ValueBase &	value
	)

Updates an accessible relation.

This function should be called by Gtk::Widget types whenever an accessible relation change must be communicated to assistive technologies.

Parameters

relation	A Gtk::Accessible::Relation.
value	A Glib::ValueBase.

◆ update_state()

void Gtk::Accessible::update_state	(	State	state,
		const Glib::ValueBase &	value
	)

Updates an accessible state.

This function should be called by Gtk::Widget types whenever an accessible state change must be communicated to assistive technologies.

Parameters

state	A Gtk::Accessible::State.
value	A Glib::ValueBase.

◆ wrap()

Glib::RefPtr< Gtk::Accessible > wrap	(	GtkAccessible *	object,
		bool	take_copy = `false`
	)

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
