Builder methods of ColorPicker, reachable through a Decorated (docs/api-style.md “Typed builders and erasure”): generic modifiers and typed ones chain in any order.
Required Methods§
Sourcefn alpha(self) -> Self
fn alpha(self) -> Self
Offer an opacity channel, and let the bound signal carry a non-opaque alpha. Honored by
the composed panel everywhere, and by every native chooser but one: a browser’s
<input type="color"> gained an alpha attribute only recently, so the web arm sets it
and stays opaque where the browser has not shipped it (docs/colorpicker.md).
Sourcefn idiom(self, idiom: PickerIdiom) -> Self
fn idiom(self, idiom: PickerIdiom) -> Self
Which chooser this well opens (see PickerIdiom).
Sourcefn native(self) -> Self
fn native(self) -> Self
Pin this well to the platform’s chooser, PickerIdiom::Native.
Sourcefn composed(self) -> Self
fn composed(self) -> Self
Pin this well to Day’s composed panel, PickerIdiom::Composed.
Sourcefn title<M>(self, t: impl IntoText<M>) -> Self
fn title<M>(self, t: impl IntoText<M>) -> Self
The chooser’s heading. Native: the iOS picker’s navigation title, the GTK dialog heading,
QColorDialog’s window title, the XAML button’s tooltip; AppKit sets the shared color
panel’s title. Composed: the panel’s own heading. A constant, Signal<String> or closure,
read once at build.
Sourcefn presets(self, presets: Vec<Color>) -> Self
fn presets(self, presets: Vec<Color>) -> Self
The swatch row the composed panel offers below its strips (ignored by the native choosers, which each have their own palette). Pass an empty vector to drop the row.
Sourcefn id(self, id: ElementId) -> Self
fn id(self, id: ElementId) -> Self
The composed well’s dayscript id (default "color-picker").
It goes here rather than on Decorate::id because what an app can reach from outside is
the layout wrapper the piece returns, and an id on that tags a node no toolkit realizes;
a tap: against it resolves to nothing while every step still reports ✓. Give two
composed pickers on one page different keys so a script can tell them apart.
The panel’s own parts carry fixed ids (color-picker-panel, -shade, -hue,
-opacity, -presets, -value, -cancel, -done); only one panel is ever open, so
they need no disambiguation.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
