There was a problem hiding this comment.
If you use references (and lifetimes) we can avoid this .clone(). I think this is likely to be on the hot path of quite a few layout thing in the future.

### What - Fixes #6246 - Very tiny bit of #4569 This PR uses emilk/egui#4588 to replace the `full_span` mechanism, which requires less boilerplate and makes it available in many more places (including tooltips). The `get_full_span()` function now lives in a `Ui` extension trait, where the rest of `re_ui` should eventually migrate (#4569). This PR also updates egui/egui_tiles/egui_commonmark to the latest commits. ### Checklist * [x] I have read and agree to [Contributor Guide](https://github.com/rerun-io/rerun/blob/main/CONTRIBUTING.md) and the [Code of Conduct](https://github.com/rerun-io/rerun/blob/main/CODE_OF_CONDUCT.md) * [x] I've included a screenshot or gif (if applicable) * [x] I have tested the web demo (if applicable): * Using examples from latest `main` build: [rerun.io/viewer](https://rerun.io/viewer/pr/6491?manifest_url=https://app.rerun.io/version/main/examples_manifest.json) * Using full set of examples from `nightly` build: [rerun.io/viewer](https://rerun.io/viewer/pr/6491?manifest_url=https://app.rerun.io/version/nightly/examples_manifest.json) * [x] The PR title and labels are set such as to maximize their usefulness for the next release's CHANGELOG * [x] If applicable, add a new check to the [release checklist](https://github.com/rerun-io/rerun/blob/main/tests/python/release_checklist)! - [PR Build Summary](https://build.rerun.io/pr/6491) - [Recent benchmark results](https://build.rerun.io/graphs/crates.html) - [Wasm size tracking](https://build.rerun.io/graphs/sizes.html) To run all checks from `main`, comment on the PR with `@rerun-bot full-check`.

* Closes emilk#4534 This PR: - Introduces `Ui::stack()`, which returns the `UiStack` structure providing information on the current `Ui` hierarchy. - **BREAKING**: `Ui::new()` now takes a `UiStackInfo` argument, which is used to populate some of this `Ui`'s `UiStack`'s fields. - **BREAKING**: `Ui::child_ui()` and `Ui::child_ui_with_id_source()` now take an `Option<UiStackInfo>` argument, which is used to populate some of the children `Ui`'s `UiStack`'s fields. - New `Area::kind()` builder function, to set the `UiStackKind` value of the `Area`'s `Ui`. - Adds a (minimalistic) demo to egui demo (in the "Misc Demos" window). - Adds a more thorough `test_ui_stack` test/playground demo. TODO: - [x] benchmarks - [x] add example to demo Future work: - Add `UiStackKind` and related support for more container (e.g. `CollapsingHeader`, etc.) - Add a tag/property system that would allow adding arbitrary data to a stack node. This data could then be queried by nested `Ui`s. Probably needed for emilk#3284. - Add support to track columnar layouts. --------- Co-authored-by: Emil Ernerfeldt <[email protected]>
