Struct egui::widget_text::RichText

pub struct RichText { /* private fields */ }

Text and optional style choices for it.

The style choices (font, color) are applied to the entire text. For more detailed control, use crate::text::LayoutJob instead.

A RichText can be used in most widgets and helper functions, e.g. Ui::label and Ui::button.

Example

use egui::{RichText, Color32};

RichText::new("Plain");
RichText::new("colored").color(Color32::RED);
RichText::new("Large and underlined").size(20.0).underline();

Implementations

impl RichText

pub fn new(text: impl Into<String>) -> Self

pub fn is_empty(&self) -> bool

pub fn text(&self) -> &str

pub fn size(self, size: f32) -> Self

Select the font size (in points). This overrides the value from Self::text_style.

pub fn extra_letter_spacing(self, extra_letter_spacing: f32) -> Self

Extra spacing between letters, in points.

Default: 0.0.

For even text it is recommended you round this to an even number of pixels, e.g. using crate::Painter::round_to_pixel.

pub fn line_height(self, line_height: Option<f32>) -> Self

Explicit line height of the text in points.

This is the distance between the bottom row of two subsequent lines of text.

If None (the default), the line height is determined by the font.

For even text it is recommended you round this to an even number of pixels, e.g. using crate::Painter::round_to_pixel.

pub fn family(self, family: FontFamily) -> Self

Select the font family.

This overrides the value from Self::text_style.

Only the families available in crate::FontDefinitions::families may be used.

pub fn font(self, font_id: FontId) -> Self

Select the font and size. This overrides the value from Self::text_style.

pub fn text_style(self, text_style: TextStyle) -> Self

Override the TextStyle.

pub fn fallback_text_style(self, text_style: TextStyle) -> Self

Set the TextStyle unless it has already been set

pub fn heading(self) -> Self

Use TextStyle::Heading.

pub fn monospace(self) -> Self

Use TextStyle::Monospace.

pub fn code(self) -> Self

Monospace label with different background color.

pub fn strong(self) -> Self

Extra strong text (stronger color).

pub fn weak(self) -> Self

Extra weak text (fainter color).

pub fn underline(self) -> Self

Draw a line under the text.

If you want to control the line color, use LayoutJob instead.

pub fn strikethrough(self) -> Self

Draw a line through the text, crossing it out.

If you want to control the strikethrough line color, use LayoutJob instead.

pub fn italics(self) -> Self

Tilt the characters to the right.

pub fn small(self) -> Self

Smaller text.

pub fn small_raised(self) -> Self

For e.g. exponents.

pub fn raised(self) -> Self

Align text to top. Only applicable together with Self::small().

pub fn background_color(self, background_color: impl Into<Color32>) -> Self

Fill-color behind the text.

pub fn color(self, color: impl Into<Color32>) -> Self

Override text color.

If not set, Color32::PLACEHOLDER will be used, which will be replaced with a color chosen by the widget that paints the text.

pub fn font_height(&self, fonts: &Fonts, style: &Style) -> f32

Read the font height of the selected text style.

pub fn append_to( self, layout_job: &mut LayoutJob, style: &Style, fallback_font: FontSelection, default_valign: Align )

Append to an existing LayoutJob

Note that the color of the RichText must be set, or may default to an undesirable color.

Example

use egui::{Style, RichText, text::LayoutJob, Color32, FontSelection, Align};

let style = Style::default();
let mut layout_job = LayoutJob::default();
RichText::new("Normal")
    .color(style.visuals.text_color())
    .append_to(
        &mut layout_job,
        &style,
        FontSelection::Default,
        Align::Center,
    );
RichText::new("Large and underlined")
    .color(style.visuals.text_color())
    .size(20.0)
    .underline()
    .append_to(
        &mut layout_job,
        &style,
        FontSelection::Default,
        Align::Center,
    );

Trait Implementations

impl Clone for RichText

fn clone(&self) -> RichText

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for RichText

fn default() -> RichText

Returns the “default value” for a type.

impl From<&String> for RichText

fn from(text: &String) -> Self

Converts to this type from the input type.

impl From<&mut String> for RichText

fn from(text: &mut String) -> Self

Converts to this type from the input type.

impl From<&str> for RichText

fn from(text: &str) -> Self

Converts to this type from the input type.

impl From<Cow<'_, str>> for RichText

fn from(text: Cow<'_, str>) -> Self

Converts to this type from the input type.

impl From<RichText> for WidgetText

fn from(rich_text: RichText) -> Self

impl PartialEq for RichText

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

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

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

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