This makes all `wgpu` features opt-in for `egui-wgpu` users.
For `eframe`, I opted to enable some `wgpu` features so users can still
use `eframe` without having to also opt-in to extra ewgpu features
(eframe is batteries-included).
Setting `desired_maximum_frame_latency` to a low value should
theoretically lead to lower latency in winit apps using `egui-wgpu`
(e.g. in `eframe` with `wgpu` backend).
* Replaces https://github.com/emilk/egui/pull/3714
* See also https://github.com/gfx-rs/wgpu/pull/4899
----
It seems like `desired_maximum_frame_latency` has no effect on my Mac. I
lowered my monitor refresh-rate to 30Hz to test, and can see no
difference between `desired_maximum_frame_latency` of `0` or `3`.
Before when experimenting with changing the global `DESIRED_NUM_FRAMES`
in `wgpu` I saw a huge difference, so I wonder what has changed.
I verified that `set_maximum_drawable_count` is being called with either
`1` or `2`, but I perceive no difference between the two.
This PR adds the following APIs, which I found to be missing while
working on https://github.com/rerun-io/rerun/pull/4879:
- `Response::decidedly_dragged()`: tests if the corresponding widget is
being decidedly dragged
- `Memory::dragged_id()`: returns the ID of the dragged widget, if any
The `egui_winit::State` contains both the `clipboard` and `allow_ime`,
but these are both private fields. In our implementation we use
`egui_winit` to do most of the lifting, but it would come really in
handy if we could access these values.
Instead of making the fields `pub` we opted for separate get/set
functions, that way calling side can't freely replace any of the values
fully and it's more in line with the style of the rest of the codebase.

* Closes https://github.com/emilk/egui/issues/3841⚠️ Breaking change!
This defines `response.hovered()` to never be true if any other widget
is being dragged.
If you want to detect if a widget is being hovered while another widget
is being dragged, use the new `response.contains_pointer` instead. This
is necessaert for things like drag-and-drop targets.
Overall, this removes special-casing of non-interactive widgets.

Added Viewport reinitialization and Window recreation for Android on
resume event.

How text editing behaves depends on what OS we are running on.
`target_os` is a compile-time check, but `ctx.os()` is a runtime check,
that works also on web.

This breaking change seems to have snuck in during #3649. Previously it
would never consume these, today it consumes them unconditionally, and
with this change it'll ~~only consume them if egui wants text input~~
never consume them.
This is a blocker for updating our application, sadly :(
This broke in https://github.com/emilk/egui/pull/3172
Since 0.24.1, `stable_dt` has been fixed at 1/60s, which is a little bit
_too_ stable.
The code issue was the logic for asking "Is this the result of an
immeditate repaint?" was completely broken (always returning false).
* Closes https://github.com/emilk/egui/issues/3830
Added error messages when scaling to invalid sizes instead of panicking
through unwrap, returning to previous behavior.
Closes <https://github.com/emilk/egui/issues/3825>.
* 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

Closes#3759
Apparently the font implementation uses a distance check to decide if
the font(or whatever) need recalculations, after dpi changed:
8d4de866d4/crates/epaint/src/text/fonts.rs (L381-L382)
This leads to warnings when the pixel_per_point diff is very low and
spams the log. (<- this happens for me if i resize my window on kwin,
e.g. maximize it)
(I don't want to debate if the float difference generally makes sense,
so if you want to rework that instead just close this pr)

Closes <https://github.com/emilk/egui/issues/THE_RELEVANT_ISSUE>.
Add option to use the scroll input from both directions to scroll the
enabled direction if scrolling is enabled for only one direction. This
can be used to allow horizontal scrolling without pressing shift if
vertical scrolling is disabled.
Closes <https://github.com/emilk/egui/issues/3624>.
This feels awful, @emilk why does this have to be an Arc?
Should the Arc be replaced with a new one when set_undoer is called, or
should it just replace the undoer inside the Arc?
Closes#3436
As described in #576, the method `Memory::layer_id_at` expands the
hit-testing region for every `Area` slightly. This is necessary so that,
when the user clicks to resize a `Window`, the mouse input isn't routed
to a different `Window`.
For non-resizable `Area`s (such as dropdown menus, context menus, date
pickers, and any non-resizable `Window`), this causes them to be
surrounded by a "dead zone" where any underlying widgets can't be
hovered or clicked. The effect is particularly noticeable in menu bars.
This commit adds a persisted `edges_padded_for_resize` property to
`Area`, which is `true` when the `Area` belongs to a resizable `Window`
and `false` for all other `Area`s. The hit-testing region is only
expanded when this property is `true`.

This PR replaces an old one with many problems (no collapse icon, the
header background was not funny colored, ugly...). It fixes those
problems.
It implements the highlight of the header to the focused window. And
allows the rest of the application to know the selected window. It
allows, for instance, to display multiple windows with images and some
additional meta information about those images on the side panel of the
main window. The side panel updates itself according to the selected
image window.
* Added a theme color for the selected window header.
* Added a function to retrieve the LayerId of the focused window.
* Implemented a simple demo of this function in the demo app where a
message states if the Option window is focused (at the bottom of the
Options window).
A technical point:
The header color is applied with a transparency of 125 so the
collapsible button becomes visible.
The reason is that the collapsible button is rendered before the rest of
the header and before the header size is known.
We cannot draw the background before knowing this value, so rendering
with transparency is a solution to see the collapsible button through
the header background.
This PR has been sponsored by my company, which left me to do it during
my work time.
This is part of an evil plan to convince them to switch to rust for new
projects :)

The minimum filled width is adapted to the radius and the animation is
disabled so it renders correctly.
