Struct ColorPicker 

pub struct ColorPicker<'a, Message, Theme = Theme>
where
    Message: Clone,
    Theme: Catalog + Catalog,
{ /* private fields */ }

An input element for picking colors.

Example

#[derive(Clone, Debug)]
enum Message {
    Open,
    Cancel,
    Submit(Color),
}

let color_picker = ColorPicker::new(
    true,
    Color::default(),
    Button::new(Text::new("Pick color"))
        .on_press(Message::Open),
    Message::Cancel,
    Message::Submit,
);

Implementations

impl<'a, Message, Theme> ColorPicker<'a, Message, Theme>

where Message: 'a + Clone, Theme: 'a + Catalog + Catalog + Catalog,

pub fn new<U, F>( show_picker: bool, color: Color, underlay: U, on_cancel: Message, on_submit: F, ) -> Self

where U: Into<Element<'a, Message, Theme, Renderer>>, F: 'static + Fn(Color) -> Message,

Creates a new ColorPicker wrapping around the given underlay.

It expects: * if the overlay of the color picker is visible. * the initial color to show. * the underlay Element on which this ColorPicker will be wrapped around. * a message that will be send when the cancel button of the ColorPicker is pressed. * a function that will be called when the submit button of the ColorPicker is pressed, which takes the picked Color value.

pub fn style(self, style: impl Fn(&Theme, Status) -> Style + 'a) -> Self

where <Theme as Catalog>::Class<'a>: From<StyleFn<'a, Theme, Style>>,

Sets the style of the ColorPicker.

pub fn class(self, class: impl Into<<Theme as Catalog>::Class<'a>>) -> Self

Sets the class of the input of the ColorPicker.

fn from(color_picker: ColorPicker<'a, Message, Theme>) -> Self
