What

Right-click the name of any space view to get the option to copy its contents as a screenshot, or save it to disk:

->

Details

The implementation simply takes a full-screen screenshot and crops the result.

The previous attempt (behind a feature-flag) only captured things that were rendered with re_renderer, i.e. did not include any egui elements, like labels. So it also only worked on spatial views. This PR work on all space views, and could also be extended to work on containers etc.

Limitations

Not yet implemented on web. See #8264

I'd the screenshot option on this menu

right click on the tab unfortunately selects the view, meaning that one can't have selection highlights on the screenshot

Looks all good and straight forward.

the only thing that I didn't quite get is what removes the SpaceViewRectPublisher again from the cache for a view that's hidden. But it works 🤷

[Wumpf]

for later consideration: it was actually nice to have a context menu inside the view.

your ide went off the rails here? Doesn't make sense to group things under pub use self::.

[emilk]

I think it makes sense - it makes it obvious that these are public exports of things in this crate, rather than e.g. re-exports from some other crate
