Struct DateRangeEdit 

pub struct DateRangeEdit { /* private fields */ }

Two-handle date picker over Signal<Option<DateRange>>. See the module docs for the visual layout and behaviour.

Implementations

impl DateRangeEdit

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

Create a date-range picker bound to value.

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

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

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

Restrict the selectable start and end dates to those on or after d.

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

Restrict the selectable start and end dates to those on or before d.

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

Override the strftime-subset format pattern for both halves (e.g. "%d/%m/%Y"). Defaults to the locale-derived pattern.

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

Placeholder shown in the start half when no date is set.

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

Placeholder shown in the end half when no date is set.

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

Override which weekday appears in the first column of the calendar popup.

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 both halves read-only; the calendar button is also disabled.

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

Accessible label for the wrapper Role::DateInput node. When not set, falls back to the localized date-range-edit-name message.

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

How both halves handle invalid or out-of-range text on blur / Enter. Defaults to ValidationBehavior::AutoCorrect.

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

How the trailing (end) half claims horizontal space. The leading (start) half always sizes to its natural mask width; the end half follows this policy. Default WidthPolicy::Default (natural width); pass WidthPolicy::Fill to make the end half absorb extra space the parent offers.

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

Show a plain single-line tooltip on hover. Mutually exclusive with the rich / composite tooltip slots — this setter clears the other two so the last call wins.

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

Show a rich tooltip sourced from the registry by key. Mutually exclusive with the plain / composite tooltip slots — this setter clears the other two so the last call wins.

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

Show a rich tooltip from an inline TooltipContent value. Mutually exclusive with the plain / registry-key tooltip slots — this setter clears the other two so the last call wins.

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

Show a composite tooltip whose body is an arbitrary widget tree. Mutually exclusive with the plain / rich tooltip slots — this setter clears the other two so the last call wins.

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

Reactive handle on the composed validation feedback (worse of the two halves — Invalid > Corrected > Valid > Pristine).

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

Callback invoked whenever the range changes (including when one half clears its value). Receives the new Option<DateRange> and an EventContext for dispatching intents or side effects.

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

Clone the underlying Signal<Option<DateRange>> for external binding.

Trait Implementations

impl Debug for DateRangeEdit

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

Formats the value using the given formatter.

impl Widget for DateRangeEdit

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).
