Struct HexColorInput 

pub struct HexColorInput { /* private fields */ }

Single-line hex color editor.

Implementations

impl HexColorInput

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

Bind to a non-nullable color signal. Empty / invalid input surfaces an error and keeps the previous value. Commits on Enter or blur.

pub fn nullable(value: Signal<Option<Color>>) -> Self

Bind to a nullable color signal. Empty input commits None; invalid input surfaces an error and keeps the previous value. Commits on Enter or blur.

pub fn alpha_enabled(self, enabled: bool) -> Self

Enable or disable the alpha channel (#RRGGBBAA form). Default false (#RRGGBB only). When enabled, the input mask and parser both switch to the 8-digit form; existing values are immediately reformatted.

pub fn short_form_enabled(self, enabled: bool) -> Self

Allow CSS #RGB short-form input (each digit doubles: #F0A → #FF00AA). Default true. When committed, the short form is expanded and a Corrected feedback is shown to the user.

pub fn require_hash(self, required: bool) -> Self

Require the # prefix during input. Default true. Set to false to accept bare RRGGBB hex digits (e.g. CSS custom property editors).

pub fn uppercase(self, upper: bool) -> Self

Normalize committed values to uppercase hex digits. Default true (#FF0000). Set to false for lowercase (#ff0000). Existing values are reformatted immediately.

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

Attach a visible label above the field and use it as the AT name.

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

Placeholder text shown when the field is empty. Defaults to the framework’s locale-specific #RRGGBB / #RRGGBBAA hint.

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

Put the field in read-only mode; the value is displayed but cannot be edited. Forwarded to the inner TextInput.

pub fn width(self, width: f32) -> Self

Set a minimum intrinsic width for the field in logical pixels.

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

Called after a successful commit with the new color value (None on a nullable binding when the field is cleared). Not called when the previous and new values are identical.

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

Called after a commit attempt when the input is invalid, with the raw typed string. The field is left as-is so the user can correct the value.

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

Attach a plain single-line tooltip shown after the standard hover delay.

Mutually exclusive with Self::rich_tooltip, Self::rich_tooltip_content, and Self::composite_tooltip — each setter clears the other three so the last call wins.

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

Attach a rich tooltip driven by a registry key.

Mutually exclusive with Self::tooltip, Self::rich_tooltip_content, and Self::composite_tooltip — each setter clears the other three so the last call wins.

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

Attach a rich tooltip from inline crate::tooltip::TooltipContent.

Mutually exclusive with Self::tooltip, Self::rich_tooltip, and Self::composite_tooltip — each setter clears the other three so the last call wins.

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 — each setter clears the other three so the last call wins.

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

Reactive handle on the inner TextInput’s published validation feedback. Mirrors the inner field’s signal after build().

Trait Implementations

impl Debug for HexColorInput

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

Formats the value using the given formatter.

impl Widget for HexColorInput

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).
