0.27.0 - Nicer menus and new hit test logic

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.

egui changelog

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.

⚠️ BREAKING

• Response::clicked* and Response::dragged* may lock the Context, so don't call it from a Context-locking closure.
• Response::clicked_by will no longer be true if clicked with keyboard. Use Response::clicked instead.
• Memory::focus has been renamed Memory::focused
• Area::new now takes an Id by argument #4115
• Change the definition of clicked_by #4192

☰ Menu related improvements

• Add some distance between parent menu and submenu #4230
• Add Area::sense and improve hit-testing of buttons in menus #4234
• Improve logic for when submenus are kept open #4166
• Better align menus with the button that opened them #4233
• Hide hover UI when showing the context menu #4138 (thanks @abey79!)
• CSS-like Shadow with offset, spread, and blur #4232
• On touch screens, press-and-hold equals a secondary click #4195

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

✨ 0.24 Highlights

You can now spawn multiple native windows on supported backends (e.g. eframe), using the new viewport API (#3172).

You can easily zoom any egui app using Cmd+Plus, Cmd+Minus or Cmd+0, just like in a browser (#3608).

Scrollbars are now hidden by default until you hover the ScrollArea (#3539).

⭐ Added

• Multiple viewports/windows #3172 (thanks @konkitoman!)

🔧 Changed

• Replace Id::null() with Id::NULL #3544
• Update MSRV to Rust 1.72 #3595
• Update puffin to 0.18 #3600

⚠️ BREAKING

• egui::gui_zoom::zoom_with_keyboard_shortcuts is gone, replaced with Options::zoom_with_keyboard, which is true by default
• Spacing::scroll_bar_X has been moved to Spacing::scroll_bar.X
• Context::set_pixels_per_point now calls Context::set_zoom_level, and it may make sense for you to call that directly instead
• If you are using eframe, check out the breaking changes in the eframe changelog

For integrations

There are several changes relevant to integrations.

• Added crate::RawInput::viewports with information about all active viewports
• The repaint callback set by Context::set_request_repaint_callback now points to which viewport should be repainted
• Context::run now returns a list of ViewportOutput in FullOutput which should result in their own independent windows
• There is a new Context::set_immediate_viewport_renderer for setting up the immediate viewport integration
• If you support viewports, you need to call Context::set_embed_viewports(false), or all new viewports will be embedded (the default behavior)
