chore(deps): bump egui_extras from 0.33.3 to 0.35.0

[dependabot]

Bumps egui_extras from 0.33.3 to 0.35.0.

Release notes

Sourced from egui_extras's releases.

0.35.0 - Inspection, egui_mcp, classes and improved IME

egui is an easy-to-use immediate mode GUI for Rust that runs on both web and native.

Try it now: https://www.egui.rs/

egui development is sponsored by Rerun, a startup building an SDK for visualizing streams of multimodal data.

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):

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| {
    ...
});

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.
