pub fn load_system_fonts(self) -> Self

Loads system fonts

pub fn load_font<P: AsRef<Path>>(&self, path: P) -> Result<String, FltkError>

let app = app::App::default();
let font = app.load_font("font.ttf").unwrap();
let mut frame = frame::Frame::new(0, 0, 400, 100, "Hello");
frame.set_label_font(Font::by_name(&font));
