Struct vizia::context::AccessNode

source ·
pub struct AccessNode { /* private fields */ }
Expand description

Wrapper around an accesskit node builder, a node id, and a list of children to be added to the node.

Implementations§

source§

impl AccessNode

source

pub fn new_from_parent(parent_id: NodeId, index: usize) -> AccessNode

source

pub fn add_child(&mut self, child: AccessNode)

Adds a child accessibility node.

source

pub fn set_role(&mut self, role: Role)

Sets the role of the node.

source

pub fn set_text_direction(&mut self, text_direction: TextDirection)

Sets the direction of any text within the node.

source

pub fn set_text_selection(&mut self, text_selection: TextSelection)

Sets the specified selection of any text within the node.

source

pub fn set_bounds(&mut self, bounds: BoundingBox)

Sets the accessibility bounds of the node. This is not the same as the layout bounds.

source

pub fn set_value(&mut self, value: impl Into<Box<str>>)

Sets the value of a node.

source

pub fn set_character_lengths(&mut self, character_lengths: impl Into<Box<[u8]>>)

source

pub fn set_character_positions( &mut self, character_positions: impl Into<Box<[f32]>> )

source

pub fn set_character_widths(&mut self, character_widths: impl Into<Box<[f32]>>)

source

pub fn set_word_lengths(&mut self, word_lengths: impl Into<Box<[u8]>>)

source

pub fn set_numeric_value_step(&mut self, value: f64)

source

pub fn set_numeric_value(&mut self, value: f64)

source

pub fn set_numeric_value_jump(&mut self, value: f64)

source

pub fn set_min_numeric_value(&mut self, value: f64)

source

pub fn set_max_numeric_value(&mut self, value: f64)

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
