Struct Eyedropper 

pub struct Eyedropper { /* private fields */ }

The button that arms an eyedropper, which looks pressed until a color is picked or Escape disarms it. The color comes from an EyedropperArea or from EyedropperState::pick: nothing here can read the screen.

use ravenrs_core::{Color, Size};
use ravenrs_widgets::{ContentSpace, Eyedropper, EyedropperArea, EyedropperState};

let dropper = EyedropperState::new().on_pick(|color| println!("{color:?}"));
let button = Eyedropper::new(&dropper);
let area = EyedropperArea::new(&dropper, |at| Some(Color::rgb(at.x / 300.0, at.y / 200.0, 0.5)))
    .space(ContentSpace::Fit(Size::new(300.0, 200.0)))
    .size(300.0, 200.0);
