Struct DateEdit 

pub struct DateEdit { /* private fields */ }

Single-line date input with optional calendar popover. See the module docs for the full feature list.

Implementations

impl DateEdit

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

Construct a date editor bound to a nullable date signal.

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

Per-call style override for the date-edit chrome.

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

Construct from a non-nullable date signal. Internally backed by a Signal<Option<Date>> proxy that mirrors the source in both directions. The placeholder is unused — the proxy is always initialized to Some(value.get()) and the mirror keeps it non-empty.

pub fn min_date(self, d: Date) -> Self

Clamp the selectable range from below. Dates earlier than d are rejected on commit and are shown as disabled in the calendar popover.

pub fn max_date(self, d: Date) -> Self

Clamp the selectable range from above. Dates later than d are rejected on commit and are shown as disabled in the calendar popover.

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

Override the locale-derived format pattern (strftime subset, see crate::common::datetime::pattern).

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

Text displayed when the bound value is None. Defaults to empty (no placeholder rendered).

pub fn first_day_of_week(self, w: Weekday) -> Self

Override which weekday heads the calendar’s column grid. Defaults to the locale’s convention if not set.

pub fn show_calendar_button(self, show: bool) -> Self

Show or hide the trailing calendar-icon trigger button that opens the calendar popover. Default true.

pub fn calendar_popover_placement(self, p: OverlayPlacement) -> Self

Override where the calendar popover appears relative to the field. Default is [OverlayPlacement::BelowPreferred].

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

Make the field read-only: text is selectable and copyable but not editable, and step keys are suppressed.

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

How parse failures are surfaced. Default ValidationBehavior::AutoCorrect (clamp + announce); switch to ValidationBehavior::Reject for strict-validation form contexts.

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

How the widget claims horizontal space. Default WidthPolicy::Default — the field sizes to its natural mask-derived width. Switch to WidthPolicy::Fill to make the field stretch to fill the parent’s offered width (toolbar / inspector pattern).

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

Reactive handle on the live validation feedback (mirrored from the inner field). Composites that want to render their own feedback UI elsewhere can bind to this; the default ValidationStrip slot below the field uses it internally.

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

Set the accessible label for the field (also shown by any paired FormLayout label slot). Defaults to the localized “Date” string.

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

Register a callback fired on every committed value change with the new Option<Date> and a live EventContext. Fires only on user-driven commits (typing + blur, Enter, calendar selection), not on external writes to the bound signal.

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

Return a clone of the bound value signal for external observation.

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

Attach a plain single-line tooltip shown after a hover delay. Mutually exclusive with Self::rich_tooltip, Self::rich_tooltip_content, and Self::composite_tooltip — this call clears those slots.

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

Attach a rich tooltip looked up by registry key. Mutually exclusive with Self::tooltip, Self::rich_tooltip_content, and Self::composite_tooltip — this call clears those slots.

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

Attach a rich tooltip from inline content. Mutually exclusive with Self::tooltip, Self::rich_tooltip, and Self::composite_tooltip — this call clears those slots.

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

Attach a composite tooltip whose body is an arbitrary widget tree. Mutually exclusive with Self::tooltip, Self::rich_tooltip, and Self::rich_tooltip_content — this call clears those slots.

Trait Implementations

impl Debug for DateEdit

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

Formats the value using the given formatter.

impl Widget for DateEdit

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).
