Are variable fonts supported?

[AlexOkafor]

Hi!
It wasn't clear to what extent otf/ttf was supported:

let mut fonts = FontDefinitions::default();

// Install my own font (maybe supporting non-latin characters):
fonts.font_data.insert("my_font".to_owned(),
   FontData::from_static(include_bytes!("../../fonts/Ubuntu-Light.ttf"))); // .ttf and .otf supported

If I have a font that has bold, semibold, etc built into 1 file does egui support loading those styles from that file?

myfont-variable.ttf

Or should I be creating separate font families from separate ttf files?

myfont-bold.ttf
myfont-semibold.ttf
myfont-thin.ttf

Or is there a better configuration to support things like different font weights?

ah I think I found the answer to my own question :)

egui/epaint/src/text/fonts.rs

Line 25 in 0571bf6

// TODO(emilk): weight (bold), italics, …

/// How to select a sized font.
#[derive(Clone, Debug, PartialEq)]
#[cfg_attr(feature = "serde", derive(serde::Deserialize, serde::Serialize))]
pub struct FontId {
    /// Height in points.
    pub size: f32,

    /// What font family to use.
    pub family: FontFamily,
    // TODO: weight (bold), italics, …
}

If there are several font faces in one file, you can use FontData::index to select the one you want.
