types whenever an accessible
relation change must be communicated to assistive technologies.
This function is meant to be used by language bindings.
relations
an array of AccessibleRelation
values
an array of GValues
, one for each relation
sourcefn update_state(&self, states: &[State])
fn update_state(&self, states: &[State])
Updates an array of accessible states.
This function should be called by Widget
types whenever an accessible
state change must be communicated to assistive technologies.
