* Closes <https://github.com/emilk/egui/issues/4490> * [x] I have followed the instructions in the PR template --- Unfortunately, this PR contains a bunch of breaking changes because `Context` no longer has one style, but two. I could try to add some of the methods back if that's desired. The most subtle change is probably that `style_mut` mutates both the dark and the light style (which from the usage in egui itself felt like the right choice but might be surprising to users). I decided to deviate a bit from the data structure suggested in the linked issue. Instead of this: ```rust pub theme: Theme, // Dark or Light pub follow_system_theme: bool, // Change [`Self::theme`] based on `RawInput::system_theme`? ``` I decided to add a `ThemePreference` enum and track the current system theme separately. This has a couple of benefits: * The user's theme choice is not magically overwritten on the next frame. * A widget for changing the theme preference only needs to know the `ThemePreference` and not two values. * Persisting the `theme_preference` is fine (as opposed to persisting the `theme` field which may actually be the system theme). The `small_toggle_button` currently only toggles between dark and light (so you can never get back to following the system). I think it's easy to improve on this in a follow-up PR :) I made the function `pub(crate)` for now because it should eventually be a method on `ThemePreference`, not `Theme`. To showcase the new capabilities I added a new example that uses different "accent" colors in dark and light mode: <img src="https://github.com/user-attachments/assets/0bf728c6-2720-47b0-a908-18bd250d15a6" width="250" alt="A screenshot of egui's widget gallery demo in dark mode using a purple accent color instead of the default blue accent"> <img src="https://github.com/user-attachments/assets/e816b380-3e59-4f11-b841-8c20285988d6" width="250" alt="A screenshot of egui's widget gallery demo in light mode using a green accent color instead of the default blue accent"> --------- Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com> |

egui and eframe examples
All the examples in this folder uses eframe to set up a window for egui. Some examples are specific to eframe, but many are applicable to any egui integration.
There are a lot more examples at https://www.egui.rs, and it has links to the source code of each example.
Also check out the official docs at https://docs.rs/egui and https://docs.rs/eframe.
Note that all the examples on master are for the latest master version of egui.
If you want to look for examples for a specific version of egui, go to that tag, e.g. https://github.com/emilk/egui/tree/latest/examples.
