BottomNavBarState

tessera_ui_basic_components::bottom_nav_bar

Struct BottomNavBarState 

Source 
pub struct BottomNavBarState { /* private fields */ }
Expand description

Holds selection & per-item ripple state for the bottom navigation bar.

selected is the currently active item index. ripple_states lazily allocates a RippleState (shared for each item) on first access, enabling ripple animations on its associated button.

Implementations§

Source§

impl BottomNavBarState

Source

pub fn new(selected: usize) -> Self

Create a new state with an initial selected index.

Source

pub fn selected(&self) -> usize

Returns the index of the currently selected navigation item.

Source

pub fn previous_selected(&self) -> usize

Returns the index of the previously selected navigation item. This is useful for animations when transitioning between selected items.

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.
