Struct TintPicker 

pub struct TintPicker<'a> { /* private fields */ }

Picks a Tint: a palette (Default, the theme’s swatches, Random) over a disk of hues around and chromas outwards, and optionally a preview of the tint in use.

It edits an Option<Tint>: None is unset, shown as the default — a label’s Tint::from_bytes of its name, say — and the Default chip sets it back.

let default = Tint::from_bytes(b"bug");
if TintPicker::new(colour, default).tone(Tone::Raised).show(ui) {
    // save `colour`
}

Implementations

impl<'a> TintPicker<'a>

pub fn new(value: &'a mut Option<Tint>, default: Tint) -> TintPicker<'a>

A picker over value, showing default while it is None.

pub fn tone(self, tone: Tone) -> Self

Draw the chips and the disk at tone: where the tint will be used. Text by default.

pub fn preview(self, on: bool) -> Self

Show the tint as link text, a label and a selected row under the disk.

pub fn show(self, ui: &mut Ui) -> bool

Draw the picker. true once a change is made — a click, or the end of a drag (the value follows the drag meanwhile) — so save the value then.
