Struct ColorEdit 

pub struct ColorEdit { /* private fields */ }

Compact color cell that opens a full ColorPicker in a popover when activated.

Implementations

impl ColorEdit

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

Bind to a non-nullable color signal. The trigger and the picker both read from and write to the same signal.

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

Bind to a nullable color signal. None is treated as transparent black for picker math; any user interaction produces a concrete Some(color). To clear back to None, compose a separate Clear button alongside the ColorEdit.

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

Enable or disable the alpha channel in the picker and the hex trigger label.

pub fn swatches(self, s: impl Into<Prop<Vec<Color>>>) -> Self

Provide a palette of preset swatches shown in the popover — statically, or reactively via a bound Signal<Vec<Color>> so the palette updates without reopening the popover.

pub fn swatch_columns(self, n: usize) -> Self

Number of columns in the preset swatch grid. Defaults to 6; clamped to at least 1.

pub fn picker_layout(self, l: ColorPickerLayout) -> Self

Select a popover layout variant — ColorPickerLayout::Compact (default, minimal height) or Standard / Wide for richer controls.

pub fn show_rgb_spinners(self, s: bool) -> Self

Show or hide the RGB (0–255) component spinners in the popover.

pub fn show_hsv_spinners(self, s: bool) -> Self

Show or hide the HSV (hue/saturation/value) component spinners in the popover.

pub fn show_hex_input(self, s: bool) -> Self

Show or hide the hex string input in the popover.

pub fn show_hex_in_trigger(self, s: bool) -> Self

Show or hide the formatted hex value as the trigger button label.

pub fn show_chevron(self, s: bool) -> Self

Show or hide the trailing chevron glyph on the trigger button.

pub fn trigger_swatch_size(self, size: f32) -> Self

Override the size of the color swatch thumbnail in the trigger button (logical pixels).

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

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

pub fn dismiss_behavior(self, b: DismissBehavior) -> Self

Override how the popover is dismissed. Default is DismissBehavior::EscapeOrClickOutside.

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

Replace the trigger button’s visible label with a static localized string. When set, the hex value is no longer displayed in the trigger (combine with .show_hex_in_trigger(false) if needed).

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 on_open(self, f: impl Fn() + 'static) -> Self

Install a callback fired when the color-picker popover opens.

The signature is Fn() (no EventContext) because on_close is invoked from the overlay-dismiss path, which has no ctx in scope. To keep the open/close pair symmetric, on_open matches. If you need ctx in a color-editing-mode callback, attach an on_tap on a sibling trigger that wakes the editor explicitly.

pub fn on_close(self, f: impl Fn() + 'static) -> Self

Install a callback fired when the color-picker popover closes. See on_open for why this is Fn() and not Fn(&mut EventContext).

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

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

Mutually exclusive with rich_tooltip, rich_tooltip_content, and composite_tooltip — calling this clears the other slots (last setter wins).

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

Attach a rich tooltip identified by a registry key.

Mutually exclusive with tooltip, rich_tooltip_content, and composite_tooltip — calling this clears the other slots (last setter wins).

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

Attach a rich tooltip from an inline TooltipContent value.

Mutually exclusive with tooltip, rich_tooltip, and composite_tooltip — calling this clears the other slots (last setter 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 tooltip, rich_tooltip, and rich_tooltip_content — calling this clears the other slots (last setter wins).

Trait Implementations

impl Debug for ColorEdit

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

Formats the value using the given formatter.

impl Widget for ColorEdit

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).
