Struct TimeEdit 

pub struct TimeEdit { /* private fields */ }

Single-line editable time-of-day field.

See the module documentation for full behaviour, pattern, and keyboard details.

Implementations

impl TimeEdit

pub fn new(value: Signal<Option<Time>>) -> Self

Construct bound to value (None = empty field; Some(t) = pre-filled time).

pub fn style(self, style: impl DateEditStyle) -> Self

Per-call DateEditStyle override (shared with DateEdit family).

pub fn required(value: Signal<Time>) -> Self

Construct with a required (non-nullable) Signal<Time>. The field never shows None; the signal and the internal Option are kept in sync.

pub fn format(self, f: TimeFormat) -> Self

Lock the field to a specific clock (12h or 24h). When this builder is not called, the field defaults to the user’s current locale via prefers_12_hour_clock (12h for en-US / en-CA / en-AU / en-NZ / en-PH / en-IN / en-PK; 24h elsewhere).

pub fn seconds(self, mode: SecondsMode) -> Self

Show or hide the seconds segment. Default: SecondsMode::Hidden.

pub fn format_pattern(self, p: impl Into<String>) -> Self

Override the strftime-subset format pattern (e.g. "%H:%M:%S"). Bypasses the locale-derived and format-derived defaults entirely.

pub fn min_time(self, t: Time) -> Self

Clamp the accepted value to at or after t (inclusive).

pub fn max_time(self, t: Time) -> Self

Clamp the accepted value to at or before t (inclusive).

pub fn step_minutes(self, n: u32) -> Self

Set the ArrowUp / ArrowDown step in minutes. Default: 1. Must be ≥ 1.

pub fn placeholder(self, text: impl Into<LocalizedString>) -> Self

Text shown when the field is empty (value is None).

pub fn enabled(self, enabled: impl Into<Prop<bool>>) -> Self

Set the enabled state, statically or reactively. Forwarded to the arena at build time.

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

Allow display-only mode: text is selectable but not editable.

pub fn validation_behavior(self, behavior: ValidationBehavior) -> Self

How parse failures are surfaced. See ValidationBehavior.

pub fn width_policy(self, policy: WidthPolicy) -> Self

How the widget claims horizontal space. See WidthPolicy. Default Default (natural mask-derived width).

pub fn validation_feedback_signal(&self) -> Signal<ValidationFeedback>

Reactive handle on the live validation feedback.

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

Set the accessible label for the field (announced by screen readers).

pub fn on_value_changed( self, f: impl Fn(Option<Time>, &mut EventContext<'_>) + 'static, ) -> Self

Callback invoked on every committed value change with the new Option<Time> and a live EventContext.

pub fn tooltip(self, text: impl Into<LocalizedString>) -> Self

Attach a plain single-line tooltip shown after a hover delay. Clears any previously set rich or composite tooltip (last call wins).

pub fn rich_tooltip(self, key: impl Into<String>) -> Self

Attach a rich tooltip identified by a registry key. Clears any previously set plain or composite tooltip (last call wins).

pub fn rich_tooltip_content(self, content: TooltipContent) -> Self

Attach an inline rich tooltip from a crate::tooltip::TooltipContent value. Clears any previously set plain or composite tooltip (last call wins).

pub fn composite_tooltip(self, content: impl Widget + 'static) -> Self

Attach a composite tooltip whose body is an arbitrary widget tree. Clears any previously set plain or rich tooltip (last call wins).

pub fn value(&self) -> Signal<Option<Time>>

The bound value signal — the same Signal passed to Self::new.

Trait Implementations

impl Debug for TimeEdit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Widget for TimeEdit

fn build(&mut self, ctx: &mut BuildContext<'_>) -> Vec<WidgetId>

Compose child widgets. Called once after the widget is placed in the arena, and again on environment change (theme switch, locale switch). Takes &mut self — store child IDs, signal handles, any state needed later. Returns the list of root child IDs (empty for leaf widgets).

fn layout_response( &self, proposal: SizeProposal, ctx: &LayoutContext<'_>, ) -> LayoutResponse

Respond to the parent’s size proposal with this widget’s wanted size, grow/shrink weights, and compression floor (see [LayoutResponse]).

fn place_children( &self, bounds: Rect, _proposal: SizeProposal, children: &mut [WidgetPlacement], _ctx: &LayoutContext<'_>, )

Position children within the allocated bounds.

fn children(&self) -> Vec<WidgetId>

Return the child widget IDs that this widget manages.

fn accessibility(&self, builder: &mut AccessNodeBuilder)

Declare this widget’s accessibility identity.

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

Concrete type name of this widget (e.g. "teksilo_widgets::button::Button"). The default implementation resolves at the impl site via std::any::type_name::<Self>(), so calls through &dyn Widget correctly dispatch to the monomorphized fn for the concrete type — getting the concrete name through the vtable without per-impl boilerplate.

fn cacheable_layout(&self) -> bool

Whether this widget’s layout_response may be memoized by the per-pass layout cache. Defaults to true.

fn paint(&self, _bounds: Rect, _canvas: &mut Canvas, _ctx: &PaintContext<'_>)

Draw the widget’s visual representation.

fn wants_after_paint(&self) -> bool

Whether this widget wants its after_paint hook to fire each frame. Returning false (the default) saves a virtual call per widget per frame for the vast majority of widgets that don’t aggregate descendant geometry.

fn after_paint(&self, _view: &WidgetTreeView<'_>, _ctx: &PaintContext<'_>)

Called once per frame after this widget’s subtree has finished painting. Receives a read-only view of the layout-resolved arena so a parent can read its descendants’ final bounds — e.g. TitleBar aggregates its drag region and control-button rects into a single HitRegions payload for the Windows backend’s WM_NCHITTEST.

fn wants_post_paint(&self) -> bool

Whether this widget wants its post_paint hook to fire each frame. Returning false (the default) saves a virtual call per widget per frame for the vast majority of widgets that don’t draw a foreground over their children.

fn post_paint( &self, _bounds: Rect, _canvas: &mut Canvas, _ctx: &PaintContext<'_>, )

Draw a foreground layer over this widget’s children.

fn wants_descendant_redirects(&self) -> bool

Whether this widget wants the AT walker to consult its a11y_redirect_descendant hook for every descendant during AT tree emission, not just its direct arena children.

fn a11y_redirect_descendant( &self, _self_id: WidgetId, _descendant: WidgetId, ) -> Option<NodeId>

Optional redirection hook for AT-tree placement of a child.

fn accessible_title_hint(&self) -> Option<String>

Suggest an accessible title to an enclosing container that wraps this widget as content — typically a modal / dialog shell that wants to propagate the inner content’s visible title as the shell’s own accessible name.

fn initial_focus_hint(&self) -> Option<WidgetId>

Optional hint that directs initial focus to a specific descendant when this widget is the root of a deferred-built modal surface.

fn accessibility_children(&self) -> Option<Vec<WidgetId>>

Optional override for the child ORDER presented to assistive technology, when it must differ from the paint / z-order child order returned by children.

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

Downcast hook. Default implementation returns None; concrete widgets override with Some(self) when they want to expose their concrete type to test-level introspection or reflection. The trait already bounds on std::any::Any so concrete types satisfy the 'static requirement.

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

Mutable counterpart of as_any. Default returns None; widgets that want to expose mutable state to tests (e.g. so a test can mutate a Scene inside a SceneView post-layout) override with Some(self). Should follow the same opt-in pattern as as_any: only widgets that opt into & introspection should opt into &mut.

fn clips_children(&self) -> bool

Whether this widget clips its children to its bounds.

fn focus_reveal_rect(&self, _bounds: Rect) -> Option<Rect>

The rectangle (in absolute tree coordinates) that best represents this widget when the framework reveals it into an ancestor scroll area on focus gain. Returning None (the default) reveals the widget’s whole bounds — correct for most controls.

fn hit_shape(&self, _local_point: Point, _bounds: Rect) -> bool

Whether the point lies inside this widget’s actual shape, not just its rectangular bounds. Consulted by hit-testing right after the bounds check: returning false for a point that is inside the bounding box makes the widget transparent to the click there, so it falls through to whatever sibling is painted underneath (the same machinery as a fully pass-through node, but shape-aware).

fn preserves_children_on_rebuild(&self) -> bool

How rebuild_single_widget treats this widget’s existing children when re-running its build().

fn tooltip_has_content(&self) -> bool

Whether this widget, used as tooltip content, currently has anything worth showing.

fn declare_shortcuts(&self) -> Vec<Shortcut>

Declare the rebindable keyboard shortcuts this widget exposes, without installing handlers. The framework calls this at arena insertion time (before build()) and at certain lazy boundaries (e.g. Switcher walks declarations on its not-yet-mounted Pending slots), so settings UIs and the ShortcutRegistry see the keystrokes the moment the owning container mounts — even if build() hasn’t run.

fn take_handler_set(&mut self) -> Option<HandlerSet>

Extract attached handler set from a WidgetWithHandlers wrapper. Called during arena insertion to transfer handlers to the WidgetNode. Default: returns None (no attached handlers).
