* Part of https://github.com/emilk/egui/issues/5113 * Part of https://github.com/emilk/egui/issues/3524 ## What This deprecates `eframe::App::update` and replaces it with two new functions: ```rs pub trait App { /// Called just before `ui`, and in the future this will /// also be called for background apps when needed. fn logic(&mut self, ctx: &egui::Context, frame: &mut Frame) { } /// Show your user interface to the user. fn ui(&mut self, ui: &mut egui::Ui, frame: &mut Frame); … } ``` Similarly, `Context::run` is deprecated in favor of `Context::run_ui`. `Plugin`s are now handed a `Ui` instead of just a `Context` in `on_begin/end_frame`. ## TODO …either in this PR or a later one * [x] Deprecate `App::update` * [x] Deprecate `Context::run` * [x] Change plugins to get a `Ui` * [x] Update kittest * [x] Change viewports to get UI:s (`show_viewport_immediate` etc) - https://github.com/emilk/egui/pull/7779 ## Later PRs * [ ] Deprecate `Panel::show` * [ ] Deprecate `CentralPanel::show` * [ ] Deprecate `CentralPanel` ?
