egui 0.32.0 changelog

This is a big egui release, with several exciting new features!

  • Atoms are new layout primitives in egui, for text and images
  • Popups, tooltips and menus have undergone a complete rewrite
  • Much improved SVG support
  • Crisper graphics (especially text!)

Let's dive in!

⚛️ Atoms

egui::Atom is the new, indivisible building block of egui (hence the name).
It lets you mix images and text in many places where you would previously only be able to add text.

Atoms is the first step towards a more powerful layout engine in egui - more to come!

Right now an Atom is an enum that can be either WidgetText, Image, or Custom.

The new AtomLayout can be used within widgets to do basic layout.
The initial implementation is as minimal as possible, doing just enough to implement what Button could do before.
There is a new IntoAtoms trait that works with tuples of Atoms. Each atom can be customized with the AtomExt trait
which works on everything that implements Into<Atom>, so e.g. RichText or Image.
So to create a Button with text and image you can now do:

let image = include_image!("my_icon.png").atom_size(Vec2::splat(12.0));
ui.button((image, "Click me!"));

Anywhere you see impl IntoAtoms you can add any number of images and text, in any order.

As of 0.32, we have ported the Button, Checkbox, RadioButton to use atoms
(meaning they support adding Atoms and are built on top of AtomLayout).
The Button implementation is not only more powerful now, but also much simpler, removing ~130 lines of layout math.

In combination with ui.read_response, custom widgets are really simple now, here is a minimal button implementation:

pub struct ALButton<'a> {
    al: AtomLayout<'a>,
}

impl<'a> ALButton<'a> {
    pub fn new(content: impl IntoAtoms<'a>) -> Self {
        Self {
            al: AtomLayout::new(content.into_atoms()).sense(Sense::click()),
        }
    }
}

impl<'a> Widget for ALButton<'a> {
    fn ui(mut self, ui: &mut Ui) -> Response {
        let Self { al } = self;
        let response = ui.ctx().read_response(ui.next_auto_id());

        let visuals = response.map_or(&ui.style().visuals.widgets.inactive, |response| {
            ui.style().interact(&response)
        });

        let al = al.frame(
            Frame::new()
                .inner_margin(ui.style().spacing.button_padding)
                .fill(visuals.bg_fill)
                .stroke(visuals.bg_stroke)
                .corner_radius(visuals.corner_radius),
        );

        al.show(ui).response
    }
}

You can even use Atom::custom to add custom content to Widgets. Here is a button in a button:

Screen.Recording.2025-07-10.at.13.10.52.mov 
let custom_button_id = Id::new("custom_button");
let response = Button::new((
    Atom::custom(custom_button_id, Vec2::splat(18.0)),
    "Look at my mini button!",
))
.atom_ui(ui);
if let Some(rect) = response.rect(custom_button_id) {
    ui.put(rect, Button::new("🔎").frame_when_inactive(false));
}

Currently, you need to use atom_ui to get a AtomResponse which will have the Rect to use, but in the future
this could be streamlined, e.g. by adding a AtomKind::Callback or by passing the Rects back with egui::Response.

Basing our widgets on AtomLayout also allowed us to improve Response::intrinsic_size, which will now report the
correct size even if widgets are truncated. intrinsic_size is the size that a non-wrapped, non-truncated,
non-justified version of the widget would have, and can be useful in advanced layout
calculations like egui_flex.

Details

❕ Improved popups, tooltips, and menus

Introduces a new egui::Popup api. Checkout the new demo on https://egui.rs:

Screen.Recording.2025-07-10.at.11.47.22.mov

We introduced a new RectAlign helper to align a rect relative to an other rect. The Popup will by default try to find the best RectAlign based on the source widgets position (previously submenus would annoyingly overlap if at the edge of the window):

Screen.Recording.2025-07-10.at.11.36.29.mov

Tooltip and menu have been rewritten based on the new Popup api. They are now compatible with each other, meaning you can just show a ui.menu_button() in any Popup to get a sub menu. There are now customizable MenuButton and SubMenuButton structs, to help with customizing your menu buttons. This means menus now also support PopupCloseBehavior so you can remove your close_menu calls from your click handlers!

The old tooltip and popup apis have been ported to the new api so there should be very little breaking changes. The old menu is still around but deprecated. ui.menu_button etc now open the new menu, if you can't update to the new one immediately you can use the old buttons from the deprecated egui::menu menu.

We also introduced ui.close() which closes the nearest container. So you can now conveniently close Windows, Collapsibles, Modals and Popups from within. To use this for your own containers, call UiBuilder::closable and then check for closing within that ui via ui.should_close().

Details

▲ Improved SVG support

You can render SVG in egui with

ui.add(egui::Image::new(egui::include_image!("icon.svg"));

(Requires the use of egui_extras, with the svg feature enabled and a call to install_image_loaders).

Previously this would sometimes result in a blurry SVG, epecially if the Image was set to be dynamically scale based on the size of the Ui that contained it. Now SVG:s are always pixel-perfect, for truly scalable graphics.

✨ Crisper graphics

Non-SVG icons are also rendered better, and text sharpness has been improved, especially in light mode.

Migration guide

We have some silently breaking changes (code compiles fine but behavior changed) that require special care:

wgpu backend features

  • wgpu 25 made the gles and vulkan backends optional
    • We missed this, so for now you need to manually opt in to those backends. Add the following to you Cargo.toml 
      wgpu = "25" # enables the wgpu default features so we get the default backends

Menus close on click by default

  • Previously menus would only close on click outside
  • Either
    • Remove the ui.close_menu() calls from button click handlers sinc...

Highlights ✨

Scene container

This release adds the Scene container to egui. It is a pannable, zoomable canvas that can contain Widgets and child Uis.
This will make it easier to e.g. implement a graph editor.

scene

Clearer, pixel perfect rendering

The tessellator has been updated for improved rendering quality and better performance. It will produce fewer vertices
and shapes will have less overdraw. We've also defined what CornerRadius (previously Rounding) means.

We've also added a tessellator test to the demo app, where you can play around with different
values to see what's produced:

tessellator-test.mp4

Check the PR for more details.

CornerRadius, Margin, Shadow size reduction

In order to pave the path for more complex and customizable styling solutions, we've reduced the size of
CornerRadius, Margin and Shadow values to i8 and u8.

Migration guide

  • Add a StrokeKind to all your Painter::rect calls #5648
  • StrokeKind::default was removed, since the 'normal' value depends on the context #5658
    • You probably want to use StrokeKind::Inside when drawing rectangles
    • You probably want to use StrokeKind::Middle when drawing open paths
  • Rename Rounding to CornerRadius #5673
  • CornerRadius, Margin and Shadow have been updated to use i8 and u8 #5563, #5567, #5568
    • Remove the .0 from your values
    • Cast dynamic values with as i8 / as u8 or as _ if you want Rust to infer the type
      • Rust will do a 'saturating' cast, so if your f32 value is bigger than 127 it will be clamped to 127
  • RectShape parameters changed #5565
    • Prefer to use the builder methods to create it instead of initializing it directly
  • Frame now takes the Stroke width into account for its sizing, so check all views of your app to make sure they still look right.
    Read the PR for more info.

egui_kittest

This release welcomes a new crate to the family: egui_kittest.
egui_kittest is a testing framework for egui, allowing you to test both automation (simulated clicks and other events),
and also do screenshot testing (useful for regression tests).
egui_kittest is built using kittest, which is a general GUI testing framework that aims to work with any Rust GUI (not just egui!).
kittest uses the accessibility library AccessKit for automatation and to query the widget tree.

kittest and egui_kittest are written by @lucasmerlin.

Here's a quick example of how to use egui_kittest to test a checkbox:

use egui::accesskit::Toggled;
use egui_kittest::{Harness, kittest::Queryable};

fn main() {
    let mut checked = false;
    let app = |ui: &mut egui::Ui| {
        ui.checkbox(&mut checked, "Check me!");
    };

    let mut harness = egui_kittest::Harness::new_ui(app);

    let checkbox = harness.get_by_label("Check me!");
    assert_eq!(checkbox.toggled(), Some(Toggled::False));
    checkbox.click();

    harness.run();

    let checkbox = harness.get_by_label("Check me!");
    assert_eq!(checkbox.toggled(), Some(Toggled::True));

    // You can even render the ui and do image snapshot tests
    #[cfg(all(feature = "wgpu", feature = "snapshot"))]
    harness.wgpu_snapshot("readme_example");
}

egui changelog

✨ Highlights

This release adds initial support for multi-pass layout, which is a tool to circumvent a common limitation of immediate mode.
You can use the new UiBuilder::sizing_pass (#4969) to instruct the Ui and widgets to shrink to their minimum size, then store that size.
Then call the new Context::request_discard (#5059) to discard the visual output and do another pass immediately after the current finishes.
Together, this allows more advanced layouts that is normally not possible in immediate mode.
So far this is only used by egui::Grid to hide the "first-frame jitters" that would sometimes happen before, but 3rd party libraries can also use it to do much more advanced things.

There is also a new UiBuilder for more flexible construction of Uis (#4969).
By specifying a sense for the Ui you can make it respond to clicks and drags, reading the result with the new Ui::response (#5054).
Among other things, you can use this to create buttons that contain arbitrary widgets.

0.29 also adds improve support for automatic switching between light and dark mode.
You can now set up a custom Style for both dark and light mode, and have egui follow the system preference (#4744 #4860).

There also has been several small improvements to the look of egui:

  • Fix vertical centering of text (e.g. in buttons) (#5117)
  • Sharper rendering of lines and outlines (#4943)
  • Nicer looking text selection, especially in light mode (#5017)

🧳 Migration

  • id_source is now called id_salt everywhere (#5025)
  • Ui::new now takes a UiBuilder (#4969)
  • Deprecated (replaced with UiBuilder):
    • ui.add_visible_ui
    • ui.allocate_ui_at_rect
    • ui.child_ui
