pub const fn bits(&self) -> i32

Gets the inner value of the Font

pub fn by_index(idx: usize) -> Font

Returns a font by index. This is the enum representation of the Font. If you change the default font for your app, which by default is Helvetica, Font::by_index(0) will still show Helvetica!

pub fn by_name(name: &str) -> Font

Gets the font by its name, can be queried via the app::get_font_names()

pub fn set_font(old: Font, new: &str)

Replace a current font with a loaded font

use fltk::enums::Font;
let font = Font::load_font("font.ttf").unwrap();
Font::set_font(Font::Helvetica, &font);

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

Load font from file.

use fltk::enums::Font;
let font = Font::load_font("font.ttf").unwrap();
Font::set_font(Font::Helvetica, &font);

pub fn get_name(&self) -> String

Get the font’s real name

Trait Implementations

impl Clone for Font

fn clone(&self) -> Font

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Font

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Font

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Font

fn cmp(&self, other: &Font) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Font

fn eq(&self, other: &Font) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Font

fn partial_cmp(&self, other: &Font) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
