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!("../../../epaint_default_fonts/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>
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>>
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.
