gboolean atk_state_set_remove_state ( AtkStateSet* set, AtkStateType type )
Removes the state for the specified type from the state set.
Note that because an
AtkStateSet 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.
