* Part of https://github.com/emilk/egui/issues/3556 ## In short You now almost never need to use `eframe::Frame` - instead use `ui.input(|i| i.viewport())` for information about the current viewport (native window), and use `ctx.send_viewport_cmd` to modify it. ## In detail This PR removes most commands from `eframe::Frame`, and replaces them with `ViewportCommand`. So `frame.close()` becomes `ctx.send_viewport_cmd(ViewportCommand::Close)`, etc. `frame.info().window_info` is now also gone, replaced with `ui.input(|i| i.viewport())`. `frame.info().native_pixels_per_point` is replaced with `ui.input(|i| i.raw.native_pixels_per_point)`. `RawInput` now contains one `ViewportInfo` for each viewport. Screenshots are taken with `ctx.send_viewport_cmd(ViewportCommand::Screenshots)` and are returned in `egui::Event` which you can check with: ``` ust ui.input(|i| { for event in &i.raw.events { if let egui::Event::Screenshot { viewport_id, image } = event { // handle it here } } }); ``` ### Motivation You no longer need to pass around the `&eframe::Frame` everywhere. This also opens the door for other integrations to use the same API of `ViewportCommand`s. |

Example how to show multiple viewports (native windows) can be created in egui when using the eframe backend.
cargo run -p multiple_viewports
For a more advanced example, see [../test_viewports].
