Expand description

Specifies the look and feel of egui.

You can change the visuals of a Ui with Ui::style_mut and of everything with crate::Context::set_style.

If you want to change fonts, use crate::Context::set_fonts instead.

Fields

override_text_style: Option<TextStyle>

If set this will change the default TextStyle for all widgets.

On most widgets you can also set an explicit text style, which will take precedence over this.

override_font_id: Option<FontId>

If set this will change the font family and size for all widgets.

On most widgets you can also set an explicit text style, which will take precedence over this.

text_styles: BTreeMap<TextStyle, FontId, Global>

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

The most convenient way to look something up in this is to use TextStyle::resolve.

If you would like to overwrite app text_styles

use egui::FontFamily::Proportional;
use egui::FontId;
use egui::TextStyle::*;

// Get current context style
let mut style = (*ctx.style()).clone();

// Redefine text_styles
style.text_styles = [
  (Heading, FontId::new(30.0, Proportional)),
  (Name("Heading2".into()), FontId::new(25.0, Proportional)),
  (Name("Context".into()), FontId::new(23.0, Proportional)),
  (Body, FontId::new(18.0, Proportional)),
  (Monospace, FontId::new(14.0, Proportional)),
  (Button, FontId::new(14.0, Proportional)),
  (Small, FontId::new(10.0, Proportional)),
].into();

// Mutate global style with above changes
ctx.set_style(style);
wrap: Option<bool>

If set, labels buttons wtc will use this to determine whether or not to wrap the text at the right edge of the Ui they are in. By default this is None.

  • None: follow layout
  • Some(true): default on
  • Some(false): default off
spacing: Spacing

Sizes and distances between widgets

interaction: Interaction

How and when interaction happens.

visuals: Visuals

Colors etc.

animation_time: f32

How many seconds a typical animation should last.

debug: DebugOptions

Options to help debug why egui behaves strangely.

explanation_tooltips: bool

Show tooltips explaining DragValue:s etc when hovered.

This only affects a few egui widgets.

Implementations

Use this style for interactive things. Note that you must already have a response, i.e. you must allocate space and interact BEFORE painting the widget!

Style to use for non-interactive widgets.

All known text styles.
