Struct NumberInput 

pub struct NumberInput { /* private fields */ }

A numeric input. Create with cx.new(|cx| NumberInput::new(cx)).

Implementations

impl NumberInput

pub fn new(cx: &mut Context<'_, Self>) -> Self

pub fn value(self, value: f64) -> Self

pub fn min(self, min: f64) -> Self

pub fn max(self, max: f64) -> Self

pub fn step(self, step: f64) -> Self

pub fn label(self, label: impl Into<SharedString>) -> Self

pub fn description(self, description: impl Into<SharedString>) -> Self

pub fn error(self, error: impl Into<SharedString>) -> Self

pub fn size(self, size: Size) -> Self

pub fn disabled(self, disabled: bool) -> Self

pub fn value_f64(&self) -> Option<f64>

The current parsed value, or None if the buffer isn’t a number.

pub fn bind(entity: &Entity<NumberInput>, signal: &Signal<f64>, cx: &mut App)

Two-way bind this input’s value to a Signal<f64>. The signal is the source of truth: the input adopts its value now (clamped to min/max), edits write back through Signal::set_if_changed, and signal writes replace the buffer without emitting NumberInputEvent. Equality guards on both directions prevent update loops.

pub fn set_value(&mut self, value: f64, cx: &mut Context<'_, Self>)

Set the value programmatically, clamped to min/max. Does not emit — a host that changed the value already knows.

pub fn set_max(&mut self, max: f64, cx: &mut Context<'_, Self>)

Raise or lower the ceiling after construction. A value above the new maximum is pulled down to it, so the field can never show one the bounds forbid.

pub fn set_min(&mut self, min: f64, cx: &mut Context<'_, Self>)

Raise or lower the floor after construction, pulling a value below it up to match.

impl NumberInput

pub fn tab_index(self, index: isize) -> Self

Where this field sits in the window’s Tab order. Fields default to 0, which walks them in render order; set this only to override that.

pub fn tab_stop(self, tab_stop: bool) -> Self

Leave the field out of the Tab order without disabling it.

pub fn focus_handle(&self) -> FocusHandle

The field’s focus handle, so a host can focus it on open.

Trait Implementations

impl EntityInputHandler for NumberInput

fn text_for_range( &mut self, range_utf16: Range<usize>, actual: &mut Option<Range<usize>>, _window: &mut Window, _cx: &mut Context<'_, Self>, ) -> Option<String>

See InputHandler::text_for_range for details

fn selected_text_range( &mut self, _ignore_disabled: bool, _window: &mut Window, _cx: &mut Context<'_, Self>, ) -> Option<UTF16Selection>

See InputHandler::selected_text_range for details

fn marked_text_range( &self, _window: &mut Window, _cx: &mut Context<'_, Self>, ) -> Option<Range<usize>>

See InputHandler::marked_text_range for details

fn unmark_text(&mut self, _window: &mut Window, _cx: &mut Context<'_, Self>)

See InputHandler::unmark_text for details

fn replace_text_in_range( &mut self, range_utf16: Option<Range<usize>>, text: &str, _window: &mut Window, cx: &mut Context<'_, Self>, )

See InputHandler::replace_text_in_range for details

fn replace_and_mark_text_in_range( &mut self, range_utf16: Option<Range<usize>>, text: &str, selected_utf16: Option<Range<usize>>, _window: &mut Window, cx: &mut Context<'_, Self>, )

See InputHandler::replace_and_mark_text_in_range for details

fn bounds_for_range( &mut self, range_utf16: Range<usize>, bounds: Bounds<Pixels>, _window: &mut Window, _cx: &mut Context<'_, Self>, ) -> Option<Bounds<Pixels>>

See InputHandler::bounds_for_range for details

fn character_index_for_point( &mut self, point: Point<Pixels>, _window: &mut Window, _cx: &mut Context<'_, Self>, ) -> Option<usize>

See InputHandler::character_index_for_point for details

impl EventEmitter<NumberInputEvent> for NumberInput

impl LineEditor for NumberInput

fn line_filter(&self, text: String) -> String

Only what can spell a number gets in — by typing, by IME, or by paste.

fn edit(&self) -> &TextEdit

fn edit_mut(&mut self) -> &mut TextEdit

fn line(&self) -> &LineState

fn line_mut(&mut self) -> &mut LineState

fn line_focus(&self) -> &FocusHandle

fn line_read_only(&self) -> bool

Accept focus, selection, and copy, but reject every mutation.

fn line_changed(&mut self, cx: &mut Context<'_, Self>)

Called after any mutation so the field can emit its change event. The element never calls cx.notify on the host’s behalf; do it here.

fn line_masked(&self) -> bool

Show bullets instead of characters, and refuse to copy or cut.

fn line_max_length(&self) -> Option<usize>

Cap on the value’s length in chars, enforced on typing and on paste the way an <input maxlength> is.

impl Render for NumberInput

fn render( &mut self, window: &mut Window, cx: &mut Context<'_, Self>, ) -> impl IntoElement

Render this view into an element tree.
