Raw mouse movement is unaccelerated and unclamped by screen boundaries,
and does not relate to any position on the screen.
It is useful in certain situations such as draggable values and 3D
cameras, where screen position does not matter.
https://github.com/emilk/egui/assets/1700581/1400e6a6-0573-41b9-99a1-a9cd305aa1a3
Added `Event::MouseMoved` for integrations to supply raw mouse movement.
Added `Response:drag_motion` to get the raw mouse movement, but will
fall back to delta in case the integration does not supply it.
Nothing should be breaking, but third-party integrations that can send
`Event::MouseMoved` should be updated to do so.
Based on #1614 but updated to the current version, and with better
fallback behaviour.
* Closes#1611
* Supersedes #1614

`glyphon` requires the screen resolution during the `prepare` stage, and
passing that to the callback's `prepare` function seems pretty trivial.

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.
* Closes https://github.com/emilk/egui/issues/3804
Add ability to select the text in labels with mouse-drag, double-click,
and keyboard (once clicked).
Hit Cmd+C to copy the text. If everything of a label with elided text is
selected, the copy command will copy the full non-elided text. IME and
accesskit _should_ work, but is untested.
You can control wether or not text in labels is selected globally in
`style.interaction.selectable_labels` or on a per-label basis in
`Label::selectable`. The default is ON.
This also cleans up the `TextEdit` code somewhat, fixing a couple
smaller bugs along the way.
This does _not_ implement selecting text across multiple widgets. Text
selection is only supported within a single `Label`, `TextEdit`, `Link`
or `Hyperlink`.

## TODO
* [x] Test
This introduces a special `Color32::PLACEHOLDER` which, during text
painting, will be replaced with `TextShape::fallback_color`.
The fallback color is mandatory to set in all text painting. Usually
this comes from the current visual style.
This lets users color only parts of a `WidgetText` (using e.g. a
`LayoutJob` or a `Galley`), where the uncolored parts (using
`Color32::PLACEHOLDER`) will be replaced by a default widget color (e.g.
blue for a hyperlink).
For instance, you can color the `⚠️`-emoji red in a piece of text red
and leave the rest of the text uncolored. The color of the rest of the
text will then depend on wether or not you put that text in a label, a
button, or a hyperlink.
Overall this simplifies a lot of complexity in the code but comes with a
few breaking changes:
* `TextShape::new`, `Shape::galley`, and `Painter::galley` now take a
fallback color by argument
* `Shape::galley_with_color` has been deprecated (use `Shape::galley`
instead)
* `Painter::galley_with_color` has been deprecated (use
`Painter::galley` instead)
* `WidgetTextGalley` is gone (use `Arc<Galley>` instead)
* `WidgetTextJob` is gone (use `LayoutJob` instead)
* `RichText::into_text_job` has been replaced with
`RichText::into_layout_job`
* `WidgetText::into_text_job` has been replaced with
`WidgetText::into_layout_job`
We were using [`tts`](https://github.com/ndarilek/tts-rs) for the
web-only screen reader. This was overkill, to say the least. It is now
replaced with ten lines of `web-sys` calls.
* Closes https://github.com/emilk/egui/issues/3602
You can now zoom any egui app by pressing Cmd+Plus, Cmd+Minus or Cmd+0,
just like in a browser. This will change the current `zoom_factor`
(default 1.0) which is persisted in the egui memory, and is the same for
all viewports.
You can turn off the keyboard shortcuts with `ctx.options_mut(|o|
o.zoom_with_keyboard = false);`
`zoom_factor` can also be explicitly read/written with
`ctx.zoom_factor()` and `ctx.set_zoom_factor()`.
This redefines `pixels_per_point` as `zoom_factor *
native_pixels_per_point`, where `native_pixels_per_point` is whatever is
the native scale factor for the monitor that the current viewport is in.
This adds some complexity to the interaction with winit, since we need
to know the current `zoom_factor` in a lot of places, because all egui
IO is done in ui points. I'm pretty sure this PR fixes a bunch of subtle
bugs though that used to be in this code.
`egui::gui_zoom::zoom_with_keyboard_shortcuts` is now gone, and is no
longer needed, as this is now the default behavior.
`Context::set_pixels_per_point` is still there, but it is recommended
you use `Context::set_zoom_factor` instead.

This PR replaces a bunch of options in `eframe::NativeOptions` with
`egui::ViewportBuilder`. For instance:
``` diff
let options = eframe::NativeOptions {
- initial_window_size: Some(egui::vec2(320.0, 240.0)),
- drag_and_drop_support: true,
+ viewport: egui::ViewportBuilder::default()
+ .with_inner_size([320.0, 240.0])
+ .with_drag_and_drop(true),
centered: true,
..Default::default()
};
```
* 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.
Thanks to `impl From<bool> for Vec2b` one can now shorten some builder
calls, like:
Previous:
```rust
egui::ScrollArea::vertical()
.auto_shrink([false; 2])
```
New:
```rust
egui::ScrollArea::vertical()
.auto_shrink(false)
```
