These are the latest versions of memoffset and arboard.
The changes to egui_glow/pure_glow allow downstream crates to not depend
on rwh 0.5, which is only needed for pure_glow (and other projects that
use glutin)
Thanks for your time & work
* Closes https://github.com/emilk/egui/issues/3941
Workspace dependencies can be annoying.
If you don't set them to `default-features=false`, then you cannot opt
out of their default features anywhere else, and get warnings if you
try.
So you set `default-features=false`, and then you need to manually opt
in to the default features everywhere else.
Or, as in my case, don't.
I don't have the energy to do this tonight, so I'll just revert.
This should help slightly with CPU/GPU parallelism when vsync is on.
I also return the time spent on vsync, which can help users figure out
how much CPU wall-time was used on non-vsync stuff
* Closes#1044

(new PR description written by @emilk)
## Overview
This PR introduces the concept of `Viewports`, which on the native
eframe backend corresponds to native OS windows.
You can spawn a new viewport using `Context::show_viewport` and
`Cotext::show_viewport_immediate`.
These needs to be called every frame the viewport should be visible.
This is implemented by the native `eframe` backend, but not the web one.
## Viewport classes
The viewports form a tree of parent-child relationships.
There are different classes of viewports.
### Root vieport
The root viewport is the original viewport, and cannot be closed without
closing the application.
### Deferred viewports
These are created with `Context::show_viewport`.
Deferred viewports take a closure that is called by the integration at a
later time, perhaps multiple times.
Deferred viewports are repainted independenantly of the parent viewport.
This means communication with them need to done via channels, or
`Arc/Mutex`.
This is the most performant type of child viewport, though a bit more
cumbersome to work with compared to immediate viewports.
### Immediate viewports
These are created with `Context::show_viewport_immediate`.
Immediate viewports take a `FnOnce` closure, similar to other egui
functions, and is called immediately. This makes communication with them
much simpler than with deferred viewports, but this simplicity comes at
a cost: whenever tha parent viewports needs to be repainted, so will the
child viewport, and vice versa. This means that if you have `N`
viewports you are poentially doing `N` times as much CPU work. However,
if all your viewports are showing animations, and thus are repainting
constantly anyway, this doesn't matter.
In short: immediate viewports are simpler to use, but can waste a lot of
CPU time.
### Embedded viewports
These are not real, independenant viewports, but is a fallback mode for
when the integration does not support real viewports. In your callback
is called with `ViewportClass::Embedded` it means you need to create an
`egui::Window` to wrap your ui in, which will then be embedded in the
parent viewport, unable to escape it.
## Using the viewports
Only one viewport is active at any one time, identified wth
`Context::viewport_id`.
You can send commands to other viewports using
`Context::send_viewport_command_to`.
There is an example in
<https://github.com/emilk/egui/tree/master/examples/multiple_viewports/src/main.rs>.
## For integrations
There are several changes relevant to integrations.
* There is a [`crate::RawInput::viewport`] with information about the
current viewport.
* The repaint callback set by `Context::set_request_repaint_callback`
now points to which viewport should be repainted.
* `Context::run` now returns a list of viewports in `FullOutput` which
should result in their own independant windows
* There is a new `Context::set_immediate_viewport_renderer` for setting
up the immediate viewport integration
* If you support viewports, you need to call
`Context::set_embed_viewports(false)`, or all new viewports will be
embedded (the default behavior).
## Future work
* Make it easy to wrap child viewports in the same chrome as
`egui::Window`
* Automatically show embedded viewports using `egui::Window`
* Use the new `ViewportBuilder` in `eframe::NativeOptions`
* Automatically position new viewport windows (they currently cover each
other)
* Add a `Context` method for listing all existing viewports

## Inspiration
- Godot because the app always work desktop or single_window because of
embedding
- Dear ImGui viewport system
## What is a Viewport
A Viewport is a egui isolated component!
Can be used by the egui integration to create native windows!
When you create a Viewport is possible that the backend do not supports
that!
So you need to check if the Viewport was created or you are in the
normal egui context!
This is how you can do that:
```rust
if ctx.viewport_id() != ctx.parent_viewport_id() {
// In here you add the code for the viewport context, like
egui::CentralPanel::default().show(ctx, |ui|{
ui.label("This is in a native window!");
});
}else{
// In here you add the code for when viewport cannot be created!
// You cannot use CentralPanel in here because you will override the app CentralPanel
egui::Window::new("Virtual Viewport").show(ctx, |ui|{
ui.label("This is without a native window!\nThis is in a embedded viewport");
});
}
```
This PR do not support for drag and drop between Viewports!
After this PR is accepted i will begin work to intregrate the Viewport
system in `egui::Window`!
The `egui::Window` i want to behave the same on desktop and web
The `egui::Window` will be like Godot Window
## Changes and new
These are only public structs and functions!
<details>
<summary>
## New
</summary>
- `egui::ViewportId`
- `egui::ViewportBuilder`
This is like winit WindowBuilder
- `egui::ViewportCommand`
With this you can set any winit property on a viewport, when is a native
window!
- `egui::Context::new`
- `egui::Context::create_viewport`
- `egui::Context::create_viewport_sync`
- `egui::Context::viewport_id`
- `egui::Context::parent_viewport_id`
- `egui::Context::viewport_id_pair`
- `egui::Context::set_render_sync_callback`
- `egui::Context::is_desktop`
- `egui::Context::force_embedding`
- `egui::Context::set_force_embedding`
- `egui::Context::viewport_command`
- `egui::Context::send_viewport_command_to`
- `egui::Context::input_for`
- `egui::Context::input_mut_for`
- `egui::Context::frame_nr_for`
- `egui::Context::request_repaint_for`
- `egui::Context::request_repaint_after_for`
- `egui::Context::requested_repaint_last_frame`

## Changes
</summary>
- `egui::Context::run`
Now needs the viewport that we want to render!
- `egui::Context::begin_frame`
Now needs the viewport that we want to render!
- `egui::Context::tessellate`
Now needs the viewport that we want to render!
- `egui::FullOutput`
```diff
- repaint_after
+ viewports
+ viewport_commands
```
- `egui::RawInput`
```diff
+ inner_rect
+ outer_rect
```
- `egui::Event`
```diff
+ WindowEvent
```
</details>
### Async Viewport
Async means that is independent from other viewports!
Is created by `egui::Context::create_viewport`
To be used you will need to wrap your state in `Arc<RwLock<T>>`
Look at viewports example to understand how to use it!
### Sync Viewport
Sync means that is dependent on his parent!
Is created by `egui::Context::create_viewport_sync`
This will pause the parent then render itself the resumes his parent!
#### ⚠️ This currently will make the fps/2 for every sync
viewport
### Common
#### ⚠️ Attention
You will need to do this when you render your content
```rust
ctx.create_viewport(ViewportBuilder::new("Simple Viewport"), | ctx | {
let content = |ui: &mut egui::Ui|{
ui.label("Content");
};
// This will make the content a popup if cannot create a native window
if ctx.viewport_id() != ctx.parent_viewport_id() {
egui::CentralPanel::default().show(ctx, content);
} else {
egui::Area::new("Simple Viewport").show(ctx, |ui| {
egui::Frame::popup(ui.style()).show(ui, content);
});
};
});
````
## What you need to know as egui user
### If you are using eframe
You don't need to change anything!
### If you have a manual implementation
Now `egui::run` or `egui::begin` and `egui::tessellate` will need the
current viewport id!
You cannot create a `ViewportId` only `ViewportId::MAIN`
If you make a single window app you will set the viewport id to be
`egui::ViewportId::MAIN` or see the `examples/pure_glow`
If you want to have multiples window support look at `crates/eframe`
glow or wgpu implementations!
## If you want to try this
- cargo run -p viewports
## This before was wanted to change
This will probably be in feature PR's
### egui::Window
To create a native window when embedded was set to false
You can try that in viewports example before:
[78a0ae8](78a0ae879e)
### egui popups, context_menu, tooltip
To be a native window

Instead of depending on android-activity directly, this exposes the
android-native-activity and android-game-activity features from Winit.
This ensures that applications can choose what android-backend they use
while also relying on Winit to decide what version of android-activity to
use - without increasing the risk of a version conflict by having a direct
dependency.
_(NB: Egui doesn't currently use the android-activity API itself)_
Since android-activity provides the `android_main()` entry point for
Android applications it's not possible to link in multiple version of
the android-activity crate and so it's particularly important to
avoid unnecessary direct dependencies that could cause a version
conflict in the future.
To help avoid the need for applications to directly depend on
android-activity the Winit crate re-exports the android-activity API
and exposes features to configure the backend so that application crates
can instead rely on Winit to pull in a compatible version of
android-activity. (This way version bumps for android-activity only
need to be synchronized with the Winit crate).
CI now enables the `android-native-activity` feature for testing.
Fixes: #2829Fixes: #2720Closes: #2834
* Update to winit 0.28
Mac trackpads pinch gestures will now generate `egui::Event::Zoom`
* Update accesskit_winit
* Try to get Android CI green
* Fix wayland compilation
* Add comment about android-activity
* Update changelogs
* Fix call to register_xlib_error_hook
* Remove native screen reader support
Use the "accesskit" feature flag to `eframe` instead.
[AccessKit](https://github.com/AccessKit/accesskit) is the future.
`tts` was a mess to compile on many platforms, so I no longer want
the native `tts` dependency.
* Update tts to 0.25
* Update changelogs
* Turn on all feature flags for package.metadata.docs.rs
* remove tts from deny.toml skip-tree
* Update web build scripts
* Update deny.toml
* Fix docs.rs build issues for eframe, egui-winit, egui_glium, egui_glow
I hope we can get rid of the `tts` crate very soon,
now that AcessKit has landed. It is only used for web atm.
Should probably be removed from all native libraries.

* squash before rebase
* Update AccessKit, introducing support for editable spinners on Windows and an important fix for navigation order on macOS
* Restore support for increment and decrement actions in DragValue
* Avoid VoiceOver race condition bug
* fix clippy lint
* Tell AccessKit that the default action for a text edit (equivalent to a click) is to set the focus. This matters to some platform adapters.
* Refactor InputState functions for AccessKit actions
* Support the AccessKit SetValue for DragValue; this is the only way for a Windows AT to programmatically adjust the value
* Same for Slider
* Properly associate the slider label with both the slider and the drag value
