Trait Implementations

impl Default for TextInput

fn default() -> Self

Returns the “default value” for a type.

impl Widget for TextInput

fn id(&self) -> &'static str

Unique identifier for this widget type

fn priority(&self) -> u8

Priority for key event handling (higher = checked first)

fn is_active(&self) -> bool

Whether the widget is currently active/visible

fn handle_key( &mut self, _key: KeyEvent, _ctx: &WidgetKeyContext<'_>, ) -> WidgetKeyResult

fn as_any(&self) -> &dyn Any

Cast to Any for downcasting

fn as_any_mut(&mut self) -> &mut dyn Any

Cast to Any for mutable downcasting

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

Convert to Box<dyn Any> for owned downcasting
