Detailed Description

An AtkStateSet determines a component's state set.

It is composed of a set of Atk::States.

Member Function Documentation

add_state()

bool Atk::StateSet::add_state

(

Atk::StateType

type

)

Adds the state of the specified type to the state set if it is not already present.

Note that because an Atk::StateSet is a read-only object, this method should be used to add a state to a newly-created set which will then be returned by #atk_object_ref_state_set. It should not be used to modify the existing state of an object. See also #atk_object_notify_state_change.

Parameters

type	An Atk::StateType.

Returns

true if the state for type is not already in set.

add_states()

void Atk::StateSet::add_states

(

const Glib::ArrayHandle< Atk::StateType > &

types

)

and_sets()

Glib::RefPtr< StateSet > Atk::StateSet::and_sets

(

const Glib::RefPtr< StateSet > &

compare_set

)

Constructs the intersection of the two sets, returning nullptr if the intersection is empty.

Parameters

compare_set

Another Atk::StateSet.

Returns

A new Atk::StateSet which is the intersection of the two sets.

clear_states()

void Atk::StateSet::clear_states

(

)

Removes all states from the state set.

contains_state()

bool Atk::StateSet::contains_state

(

Atk::StateType

type

)

Checks whether the state for the specified type is in the specified set.

Parameters

type	An Atk::StateType.

Returns

true if type is the state type is in set.

contains_states()

bool Atk::StateSet::contains_states

(

const Glib::ArrayHandle< Atk::StateType > &

types

)

const

create()

static Glib::RefPtr< StateSet > Atk::StateSet::create ( )

static

get_type()

static GType Atk::StateSet::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

AtkStateSet * Atk::StateSet::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const AtkStateSet * Atk::StateSet::gobj ( ) const

inline

Provides access to the underlying C GObject.

gobj_copy()

AtkStateSet * Atk::StateSet::gobj_copy

(

)

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

is_empty()

bool Atk::StateSet::is_empty

(

)

const

Checks whether the state set is empty, i.e. has no states set.

Returns

true if set has no states set, otherwise false.

operator=()

StateSet & Atk::StateSet::operator= ( StateSet &&  src )

noexcept

or_sets()

Glib::RefPtr< StateSet > Atk::StateSet::or_sets

(

const Glib::RefPtr< StateSet > &

compare_set

)

Constructs the union of the two sets.

Parameters

compare_set

Another Atk::StateSet.

Returns

A new Atk::StateSet which is the union of the two sets, returning nullptr is empty.

remove_state()

bool Atk::StateSet::remove_state

(

Atk::StateType

type

)

Removes the state for the specified type from the state set.

Note that because an Atk::StateSet is a read-only object, this method should be used to remove a state to a newly-created set which will then be returned by #atk_object_ref_state_set. It should not be used to modify the existing state of an object. See also #atk_object_notify_state_change.

Parameters

type	An Atk::Type.

Returns

true if type was the state type is in set.

xor_sets()

Glib::RefPtr< StateSet > Atk::StateSet::xor_sets

(

const Glib::RefPtr< StateSet > &

compare_set

)

Constructs the exclusive-or of the two sets, returning nullptr is empty.

The set returned by this operation contains the states in exactly one of the two sets.

Parameters

compare_set

Another Atk::StateSet.

Returns

A new Atk::StateSet which contains the states which are in exactly one of the two sets.

wrap()

Glib::RefPtr< Atk::StateSet > wrap ( AtkStateSet *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

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.
