Struct egui::paint::fonts::FontDefinitions

pub struct FontDefinitions {
    pub pixels_per_point: f32,
    pub font_data: BTreeMap<String, FontData>,
    pub fonts_for_family: BTreeMap<FontFamily, Vec<String>>,
    pub family_and_size: BTreeMap<TextStyle, (FontFamily, f32)>,
}

This is how you tell Egui which fonts and font sizes to use.

Fields

pixels_per_point: f32

The dpi scale factor. Needed to get pixel perfect fonts.

font_data: BTreeMap<String, FontData>

List of font names and their definitions. The definition must be the contents of either a .ttf or .otf font file.

Egui has built-in-default for these, but you can override them if you like.

fonts_for_family: BTreeMap<FontFamily, Vec<String>>

Which fonts (names) to use for each FontFamily.

The list should be a list of keys into font_data. When looking for a character glyph Egui will start with the first font and then move to the second, and so on. So the first font is the primary, and then comes a list of fallbacks in order of priority.

family_and_size: BTreeMap<TextStyle, (FontFamily, f32)>

The FontFaily and size you want to use for a specific TextStyle.

Implementations

impl FontDefinitions

pub fn ui(&mut self, ui: &mut Ui)

impl FontDefinitions

pub fn default_with_pixels_per_point(pixels_per_point: f32) -> Self

Default values for the fonts

Trait Implementations

impl Clone for FontDefinitions

pub fn clone(&self) -> FontDefinitions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FontDefinitions

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

Formats the value using the given formatter.

impl Default for FontDefinitions

pub fn default() -> Self

Returns the "default value" for a type.

impl PartialEq<FontDefinitions> for FontDefinitions

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
