Highlights

• New egui_mcp crate based on eguis new inspection protocol
• Set classes on your Uis to modify widget behavior based on surrounding context
• Improved IME

Egui inspection and egui_mcp

This release includes a new inspection protocol for egui. It allows reading the accesskit tree of a running app, as well
as sending events to control it. It's implemented via a new InspectionPlugin in the egui_inspection crate.
Eframe includes a new inspection feature. When enabled, you can enable inspection by launching the app with
EGUI_INSPECTION=1. This will cause the app to listen on port 5719.

The first inspection protocol consumer is egui_mcp.
It's a mcp server that allows your agent to see and use
egui apps. It can be used to have the agent use the app, reproduce bugs and verify its changes.
Install it via cargo install --git https://github.com/rerun-io/kittest_inspector egui_mcp and then add it to your
agent via claude mcp add egui egui-mcp.

There is also a plan of adding a general inspection gui using the same protocol, that can e.g. be used to step through
kittest tests frame by frame.

Here is claude using the mcp to try some of the egui demos (sped up by a lot, claude is slow):

• Add egui_inspection protocol and plugin #8234 by @lucasmerlin

Classes

As part of css like styling, we've added classes to egui. You can already
use them to e.g. modify widget behavior or styling based on surrounding context.
Add classes to the container:

ui.scope_builder(UiBuilder::new().with_class("my_container"), |ui| {
    ...
});       

In your widget, check if we're in my_container, to e.g. change sizes or colors:

  let in_container = ui.stack().iter().any(|s| s.classes.has("my_container")); 

Today this only works for custom widgets and ui code, but the next step will be a styling system that allows you to modify built
in widget styling based on these classes.

egui 0.34.0 changelog

Highlights from this release

• Sharper text unlocked by switching font rendering crate to skrifa
• Fade out edges of ScrollAreas
• Use Ui as the main entrypoint

Skrifa and font hinting

The font rendering backend was switched from ab_glyph to skrifa + vello_cpu. This enabled us support
font hinting and variations. It also paves the way for more font improvements in the future, like support for color
emojis and adding helpers for variations like RichText::bold.

Font hinting makes text more clear (look at the =):

We now support setting variable font parameters:

(Unfortunately there is currently a bug with variations, meaning changing them live like this won't work in practise.
There is a draft PR to fix it, but it didn't make the release)

• Replace ab_glyph with Skrifa + vello_cpu; enable font hinting #7694 by @valadaptive
• Add font variations API #7859 by @valadaptive

More Ui, less Context

egui has long had a confusing overlap in responsibilities between Context and Ui.
In particular, you could add panels to either one (or both!).
In this release, we switch from having Context be the main entrypoint, and instead provide whole-app Ui.
In egui we've replaced Context::run with Context::run_ui, and changed viewports to be given a &mut Ui instead of Context.
In eframe we've deprecated App::update replaced it with App::ui (which provides a &mut Ui instead of a &Context).

In addition to this, Ui now derefs to Context, so all code like ui.ctx().input(…) can now be written ui.input(…).
This means you are much less likely to have to use naked Contexts.
Context can still be useful though, since they implement Clone and can be sent to other threads so you can call .request_repaint on them.

• Add Context::run_ui #7736 by @emilk
• Add Deref<Target = Context> for Ui #7770 by @emilk
• Replace App::update with fn logic and fn ui #7775 by @emilk
• Rename Context::style to global_style; avoid confusion w/ Ui::style #7772 by @emilk
• Rename functions in Context to avoid confusion #7773 by @emilk
• Viewports: give the caller a Ui instead of Context #7779 by @emilk

Changed panel API

As part of the above work, we have unified the panel API.
SidePanel and TopBottomPanel are deprecated, replaced by a single Panel.
Furthermore, it is now deprecated to use panels directly on Context. Use the show_inside functions instead, acting on Uis.

This unification and simplification will make it easier to maintain and improve panels going forward.

• Add Panel to replace SidePanel and TopBottomPanel #5659 by @sharky98
• Deprecate using Panel directly on a Context #7781 by @emilk
• Deprecate CentralPanel::show #7783 by @emilk
• Deprecate Context::used_size and Context::available_rect #7788 by @emilk

(Unfortunately there is currently a bug with variations, meaning changing them live like this won't work in practise. There is a draft PR to fix it, but it didn't make the release)

More Ui, less Context

egui has long had a confusing overlap in responsibilities between Context and Ui. In particular, you could add panels to either one (or both!). In this release, we switch from having Context be the main entrypoint, and instead provide whole-app Ui. In egui we've replaced Context::run with Context::run_ui, and changed viewports to be given a &mut Ui instead of Context. In eframe we've deprecated App::update replaced it with App::ui (which provides a &mut Ui instead of a &Context).

In addition to this, Ui now derefs to Context, so all code like ui.ctx().input(…) can now be written ui.input(…). This means you are much less likely to have to use naked Contexts. Context can still be useful though, since they implement Clone and can be sent to other threads so you can call .request_repaint on them.

• Add Context::run_ui #7736 by @emilk
• Add Deref<Target = Context> for Ui #7770 by @emilk
• Replace App::update with fn logic and fn ui #7775 by @emilk
• Rename Context::style to global_style; avoid confusion w/ Ui::style #7772 by @emilk
• Rename functions in Context to avoid confusion #7773 by @emilk
• Viewports: give the caller a Ui instead of Context #7779 by @emilk

Changed panel API

As part of the above work, we have unified the panel API. SidePanel and TopBottomPanel are deprecated, replaced by a single Panel. Furthermore, it is now deprecated to use panels directly on Context. Use the show_inside functions instead, acting on Uis.

This unification and simplification will make it easier to maintain and improve panels going forward.

• Add Panel to replace SidePanel and TopBottomPanel #5659 by @sharky98
• Deprecate using Panel directly on a Context #7781 by @emilk
• Deprecate CentralPanel::show #7783 by @emilk

Highlights from this release:

• egui::Plugin a improved way to create and access egui plugins
• kitdiff, a viewer for egui_kittest image snapshots (and a general image diff tool)
• better kerning

Improved kerning

As a step towards using parley for font rendering, @valadaptive has refactored the font loading and rendering code. A result of this (next to the font rendering code being much nicer now) is improved kerning. Notice how the c moved away from the k:

egui::Plugin trait

We've added a new trait-based plugin api, meant to replace Context::on_begin_pass and Context::on_end_pass. This makes it a lot easier to handle state in your plugins. Instead of having to write to egui memory it can live right on your plugin struct. The trait based api also makes easier to add new hooks that plugins can use. In addition to on_begin_pass and on_end_pass, the Plugin trait now has a input_hook and output_hook which you can use to inspect / modify the RawInput / FullOutput.

kitdiff, a image diff viewer

At rerun we have a ton of snapshots. Some PRs will change most of them (e.g. the one that updated egui and introduced the kerning improvements, ~500 snapshots changed!). If you really want to look at every changed snapshot it better be as efficient as possible, and the experience on github, fiddeling with the sliders, is kind of frustrating. In order to fix this, we've made kitdiff. You can use it locally via

• kitdiff files . will search for .new.png and .diff.png files
• kitdiff git will compare the current files to the default branch (main/master) Or in the browser via
• going to https://rerun-io.github.io/kitdiff/ and pasting a PR or github artifact url
• linking to kitdiff via e.g. a github workflow https://rerun-io.github.io/kitdiff/?url=<link_to_pr_or_artifact>

To install kitdiff run cargo install --git https://github.com/rerun-io/kitdiff

Here is a video showing the kerning changes in kitdiff (try it yourself):

Migration guide

• egui::Mutex now has a timeout as a simple deadlock detection
  • If you use a egui::Mutex in some place where it's held for longer than a single frame, you should switch to the std mutex or parking_lot instead (egui mutexes are wrappers around parking lot)
• screen_rect is deprecated
  • In order to support safe areas, egui now has viewport_rect and content_rect.
  • Update all usages of screen_rect to content_rect, unless you are sure that you want to draw outside the safe area (which would mean your Ui may be covered by notches, system ui, etc.)

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 blocks of egui (hence their name). 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:

https://github.com/user-attachments/assets/8c649784-dcc5-4979-85f8-e735b9cdd090

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

• Add AtomLayout, abstracting layouting within widgets #5830 by @lucasmerlin
• Add Galley::intrinsic_size and use it in AtomLayout #7146 by @lucasmerlin

❕ Improved popups, tooltips, and menus

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

https://github.com/user-attachments/assets/74e45243-7d05-4fc3-b446-2387e1412c05

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):

https://github.com/user-attachments/assets/0c5adb6b-8310-4e0a-b936-646bb4ec02f7

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().

• Change popup memory to be per-viewport #6753 by @mkalte666
• Deprecate Memory::popup API in favor of new Popup API #7317 by @emilk

▲ 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.

Details

• Support text in SVGs #5979 by @cernec1999
• Fix sometimes blurry SVGs #7071 by @emilk
• Fix incorrect color fringe colors on SVG:s #7069 by @emilk
• Make Image::paint_at pixel-perfect crisp for SVG images #7078 by @emilk

✨ Crisper graphics

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

• Improve text rendering in light mode #7290 by @emilk
• Improve texture filtering by doing it in gamma space #7311 by @emilk
• Make text underline and strikethrough pixel perfect crisp #5857 by @emilk

Migration guide

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

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 since they are obsolete
  • if the menu should stay open on clicks, change the PopupCloseBehavior:

        // Change this
      ui.menu_button("Text", |ui| { /* Menu Content */ });
        // To this:
      MenuButton::new("Text").config(
          MenuConfig::default().close_behavior(PopupCloseBehavior::CloseOnClickOutside),
      ).ui(ui, |ui| { /* Menu Content */ });
    

    You can also change the behavior only for a single SubMenu by using SubMenuButton, but by default it should be passed to any submenus when using MenuButton.

Memory::is_popup_open api now requires calls to Memory::keep_popup_open

• The popup will immediately close if keep_popup_open is not called.
• It's recommended to use the new Popup api which handles this for you.
• If you can't switch to the new api for some reason, update the code to call keep_popup_open:

      if ui.memory(|mem| mem.is_popup_open(popup_id)) {
        ui.memory_mut(|mem| mem.keep_popup_open(popup_id)); // <- add this line
        let area_response = Area::new(popup_id).show(...)
      }

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.

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:

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");
}

✨ 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)

The hit test logic (what is the user clicking on?) has been completely rewritten, and should now be much more accurate and helpful. The hit test and interaction logic is run at the start of the frame, using the widgets rects from the previous frame, but the latest mouse coordinates. It enabled getting a Response for a widget before creating it using Context::read_response. This will in the future unlock more powerful widget styling options. The new hit test also allows clicking slightly outside a button and still hit it, improving the support for touch screens.

The menus have also been improved so that they both act and feel better, with no change in API. Included in this is much nicer looking shadows, supporting an offset.

For integrations

There are several changes relevant to integrations.

• Added crate::RawInput::viewports with information about all active viewports

• Properly clamp and round viewport values, preventing rare warnings #3604 (thanks @Wumpf!)

This release contains a simple and powerful image API:

// Load from web:
ui.image("https://www.example.com/some_image.png");

// Include image in the binary using `include_bytes`:
ui.image(egui::include_image!("../assets/ferris.svg"));

// With options:
ui.add(
    egui::Image::new("file://path/to/image.jpg")
        .max_width(200.0)
        .rounding(10.0),
);

The API is based on a plugin-system, where you can tell egui how to load the images, and from where.

egui_extras comes with loaders for you, so all you need to do is add the following to your Cargo.toml:

egui_extras = { version = "0.23", features = ["all_loaders"] }
image = { version = "0.24", features = ["jpeg", "png"] } # Add the types you want support for

And this to your code:

egui_extras::install_image_loaders(egui_ctx);
