Struct cacao::layer::Layer

pub struct Layer {
    pub objc: ObjcProperty,
}

Represents a CALayer.

Each widget has an underlying layer field that you can access, which offers additional rendering tools.

// Create a rounded red box
use cacao::view::View;
use cacao::color::Color;
let view = View::default();
view.set_background_color(Color::SystemRed);
view.layer.set_corner_radius(4.0);

Fields

objc: ObjcProperty

The underlying layer pointer.
