Expand description

Attributes that can be applied to text.

Where possible, attributes are KeyOrValue types; this means you can use items defined in the theme or concrete types, where appropriate.

The easiest way to construct these attributes is via the various constructor methods, such as Attribute::size or Attribute::text_color.

Examples

use druid::text::Attribute;
use druid::{theme, Color};

let font = Attribute::font_descriptor(theme::UI_FONT);
let font_size = Attribute::size(32.0);
let explicit_color = Attribute::text_color(Color::BLACK);
let theme_color = Attribute::text_color(theme::SELECTION_COLOR);
