Expand description

Describes the font data and the sizes to use.

Often you would start with FontDefinitions::default() and then add/change the contents.

This is how you install your own custom fonts:

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

// Put my font first (highest priority):
fonts.families.get_mut(&FontFamily::Proportional).unwrap()
    .insert(0, "my_font".to_owned());

// Put my font as last fallback for monospace:
fonts.families.get_mut(&FontFamily::Monospace).unwrap()
    .push("my_font".to_owned());

egui_ctx.set_fonts(fonts);

Fields

font_data: BTreeMap<String, FontData, Global>

List of font names and their definitions.

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

families: BTreeMap<FontFamily, Vec<String, Global>, Global>

Which fonts (names) to use for each FontFamily.

The list should be a list of keys into Self::font_data. When looking for a character glyph epaint 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.

Implementations

Trait Implementations

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

Specifies the default fonts if the feature default_fonts is enabled, otherwise this is the same as Self::empty.

Deserialize this value from the given Serde deserializer. Read more

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
