This adds a callback (set by `Context::set_request_repaint_callback`)
which integration can use to wake up the UI thread.
eframe (egui_web and egui_glow) will use this, replacing
`epi::Frame::request_repaint`.
Existing code calling `epi::Frame::request_repaint` should be changed
to instead call `egui::Context::request_repaint`.
This is the first callback added to the egui API, which otherwise is
completely driven by data.
The purpose of this is to remove the confusion between the two
`request_repaint` methods (by removing one). Furthermore, it makes
`epi::Frame` a lot simpler, allowing future simplifications to it
(perhaps no longer having it be `Send+Sync+Clone`).
* Add Shape::Callback to do custom rendering inside of an egui UI
* Use Rc<glow::Context> everywhere
* Remove trait WebPainter
* Add glow::Context to epi::App::setup
This adds all parts of the web "location" (URL) to frame.info().web_info, included a HashMap of the query parameters, percent-decoded and ready to go.
This lets you easily pass key-value pairs to your eframe web app.

`begin_frame`, `end_frame` is more convenient when using egui in a game engine. In particular, 0.16.0 was incompatible with https://github.com/mvlabat/bevy_egui>.
* Move window building to egui-winit
* Move icon loading to egui-winit
* `use glow::HasContext;` -> `use glow::HasContext as _;`
* Move FileStorage into epi behind a feature flag
* De-duplicate screen_size_in_pixels and native_pixels_per_point
* Move creation of FileStorage to epi
* Handle epi app output (window size changes etc) in egui-winit
* Move app and memory persistence and autosave logic to egui-winit
* fix check.sh
* Make the epi backend opt-in for egui_glium and egui_glow
* Fix persistence
* Add integration name to epi::IntegrationInfo and the demo
* Clean up Cargo.toml files and fix making egui_glium optional
* fix typo
* Make egui_glium compile without the `epi` feature
* Make egui_glow and opt-in backend for eframe
* Add egui_glow to Cargo.toml and to CI
* Reference egui_glow where egui_glium is mentioned
* Remove path-patches from root Cargo.toml
* Add instructions on how to enable the glow backend of eframe
* Speed up galley cache by only using the hash as key
This hashes the job but doesn't compare them with Eq,
which speeds up demo_with_tessellate__realistic by 5-6%,
winning back all the performance lost in
https://github.com/emilk/egui/pull/682
* Remove custom Eq/PartialEq code for LayoutJob and friends
* Silence clippy
* Unrelated clippy fixes
I've extracted all the http request code and turned it
into its own crate at <https://github.com/emilk/ehttp>.
There was never a reason for the HTTP request library to be part of
`eframe`. Much better to have it as its own crate!
This PR introduces a completely rewritten text layout engine which is simpler and more powerful. It allows mixing different text styles (heading, body, etc) and formats (color, underlining, strikethrough, …) in the same layout pass, and baked into the same `Galley`.
This opens up the door to having a syntax-highlighed code editor, or a WYSIWYG markdown editor.
One major change is the color is now baked in at layout time. However, many widgets changes text color on hovered. But we need to do the text layout before we know if it is hovered. Therefor the painter has an option to override the text color of a galley.
## Performance
Text layout alone is about 20% slower, but a lot of that is because more tessellation is done upfront. Text tessellation is now a lot faster, but text layout + tessellation still lands at a net loss of 5-10% in performance. There are however a few tricks to speed it up (like using `smallvec`) which I am saving for later. Text layout is also cached, meaning that in most cases (when all text isn't changing each frame) text tessellation is actually more important (and that's more than 2x faster!).
Sadly, the actual text cache lookup is significantly slower (300ns -> 600ns). That's because the `TextLayoutJob` is a lot bigger (it has more options, like underlining, fonts etc), so it is slower to hash and compare. I have an idea how to speed this up, but I need to do some other work before I can implement that.
All in all, the performance impact on `demo_with_tesselate__realistic` is about 5-6% in the red. Not great; not terrible. The benefits are worth it, but I also think with some work I can get that down significantly, hopefully down to the old levels.
* Use old 1.51 toolchain instead of bleeding edge
1.52 and 1.53 has problems with incremental compilation,
so some people chose to stay on 1.51 for now.
So let's make sure egui supports 1.51 for a while!
* Update to cint 0.2.2 to get rust 1.51.0 compatability
* implement cint for color types under feature flag
* upgrade to cint 0.2, remove from default features
* upgrade to cint 0.2.1, add a couple more from/into implementations
* changelog entry
* fix typo in changelog
* sort dependency
* fmt
* init work
* implement deferred deserialization
* many improvements
* rename `DataElement` -> `AnyMapElement`
* make `data` in `Memory` as public field of type with public interface
* make interface more rich
* transform most unwraps to proper error handling
* make `AnyMap` store by `TypeId`, so now individual type can be counted and reset
* improve storing TypeId between different rust versions
* rewrite system widgets to use AnyMap
* refactor everything
* replace `serde_json` -> `ron`
* move `any_map` to module
* separate `AnyMap` into `AnyMapId` and `serializable::AnyMapId` in order to not require `serde` traits in methods
* add `AnyMap` and `serializable::AnyMap` that stores elements just by type, without `Id`
* write documentation
* change tooltips and color picker to use `Memory::data_temp`
* fix bugs and docs
* Apply suggestions from code review
