An AtkStateSet determines a component's state set. It is composed of a set of AtkStates.
AtkStateSet* atk_state_set_new (void);
Creates a new empty state set.
| Returns : | a new AtkStateSet |
gboolean atk_state_set_is_empty (AtkStateSet *set);
Checks whether the state set is empty, i.e. has no states set.
set : |
an AtkStateType |
| Returns : | TRUE if set has no states set, otherwise FALSE
|
gboolean atk_state_set_add_state (AtkStateSet *set, AtkStateType type);
Add a new state for the specified type to the current state set if it is not already present.
set : |
an AtkStateSet |
type : |
an AtkStateType |
| Returns : | TRUE if the state for type is not already in set.
|
void atk_state_set_add_states (AtkStateSet *set,
AtkStateType *types,
gint n_types);
Add the states for the specified types to the current state set.
set : |
an AtkStateSet |
types : |
an array of AtkStateType |
n_types : |
The number of elements in the array |
void atk_state_set_clear_states (AtkStateSet *set);
Removes all states from the state set.
set : |
an AtkStateSet |
gboolean atk_state_set_contains_state (AtkStateSet *set, AtkStateType type);
Checks whether the state for the specified type is in the specified set.
set : |
an AtkStateSet |
type : |
an AtkStateType |
| Returns : | TRUE if type is the state type is in set.
|
gboolean atk_state_set_contains_states (AtkStateSet *set, AtkStateType *types, gint n_types);
Checks whether the states for all the specified types are in the specified set.
set : |
an AtkStateSet |
types : |
an array of AtkStateType |
n_types : |
The number of elements in the array |
| Returns : | TRUE if all the states for type are in set.
|
gboolean atk_state_set_remove_state (AtkStateSet *set, AtkStateType type);
Removes the state for the specified type from the state set.
set : |
an AtkStateSet |
type : |
an AtkType |
| Returns : | TRUE if type was the state type is in set.
|
AtkStateSet* atk_state_set_and_sets (AtkStateSet *set,
AtkStateSet *compare_set);
Constructs the intersection of the two sets, returning NULL if the
intersection is empty.
set : |
an AtkStateSet |
compare_set : |
another AtkStateSet |
| Returns : | a new AtkStateSet which is the intersection of the two sets. |
AtkStateSet* atk_state_set_or_sets (AtkStateSet *set,
AtkStateSet *compare_set);
Constructs the union of the two sets.
set : |
an AtkStateSet |
compare_set : |
another AtkStateSet |
| Returns : | a new AtkStateSet which is the union of the two sets,
returning NULL is empty.
|
AtkStateSet* atk_state_set_xor_sets (AtkStateSet *set,
AtkStateSet *compare_set);
Constructs the exclusive-or of the two sets, returning NULL is empty.
The set returned by this operation contains the states in exactly
one of the two sets.
set : |
an AtkStateSet |
compare_set : |
another AtkStateSet |
| Returns : | a new AtkStateSet which contains the states which are in exactly one of the two sets. |
