**Solution :**
When `request_redraw()` is performed in Minimized state, the occasional
screen tearing phenomenon has disappeared.
( Probably expected to be the effect of #4814 )
To address the issue of the `Immediate Viewport` not updating in
Minimized state, we can call `request_redraw()`.

I've been meaning to look into this for a while but finally bit the
bullet this week. Contrary to what I initially thought, the problem of
blurry lines is unrelated to feathering because it also happens with
feathering disabled.
The root cause is that lines tend to land on pixel boundaries, and
because of that, frequently used strokes (e.g. 1pt), end up partially
covering pixels. This is especially noticeable on 1ppp displays.
There were a couple of things to fix, namely: individual lines like
separators and indents but also shape strokes (e.g. Frame).
Lines were easy, I just made sure we round them to the nearest pixel
_center_, instead of the nearest pixel boundary.
Strokes were a little more complicated. To illustrate why, here’s an
example: if we're rendering a 5x5 rect (black fill, red stroke), we
would expect to see something like this:
The fill and the stroke to cover entire pixels. Instead, egui was
painting the stroke partially inside and partially outside, centered
around the shape’s path (blue line):
Both methods are valid for different use-cases but the first one is what
we’d typically want for UIs to feel crisp and pixel perfect. It's also
how CSS borders work (related to #4019 and #3284).
Luckily, we can use the normal computed for each `PathPoint` to adjust
the location of the stroke to be outside, inside, or in the middle.
These also are the 3 types of strokes available in tools like Photoshop.
This PR introduces an enum `StrokeKind` which determines if a
`PathStroke` should be tessellated outside, inside, or _on_ the path
itself. Where "outside" is defined by the directions normals point to.
Tessellator will now use `StrokeKind::Outside` for closed shapes like
rect, ellipse, etc. And `StrokeKind::Middle` for the rest since there's
no meaningful "outside" concept for open paths. This PR doesn't expose
`StrokeKind` to user-land, but we can implement that later so that users
can render shapes and decide where to place the stroke.
### Strokes test
(blue lines represent the size of the rect being rendered)
`Stroke::Middle` (current behavior, 1px and 3px are blurry)
`Stroke::Outside` (proposed default behavior for closed paths)
`Stroke::Inside` (for completeness but unused at the moment)
### Demo App
The best way to review this PR is to run the demo on a 1ppp display,
especially to test hover effects. Everything should look crisper. Also
run it in a higher dpi screen to test that nothing broke 🙏.

Fix: Ensures correct IME behavior when the text input area gains or

Fix: Handling `state.ime_enabled` in multiple `TextEdit`.
Fix: A symptom of characters being copied when there are multiple
TextEdits.

Fix Issues: When focus is moved elsewhere, you must set
`state.ime_enabled = false`, otherwise the IME will have problems when
focus returns.
Fix Issues: A symptom of characters being copied when there are multiple
TextEdits.
Deletes all current `IME events`, preventing them from being copied to
`other TextEdits`, without saving the `TextEdit ID`,
( Related Issues: Some `LINUX` seem to trigger an IME enable event on
startup. So, when we gained focus, we do `state.ime_enabled = false`. )
When a `ScrollArea` is added to a `Ui` or its contents change
dynamically, the contents will briefly escape the container. This occurs
because `ScrollArea` internally maintains `content_is_too_large` flags,
from which it determines when to clip. The `content_is_too_large` flags
are calculated after painting, so they always lag one frame behind. This
can lead to flickering.
To fix this, I have changed the `ScrollArea` so that it always clips
scrollable content. I believe that this should fix things without
negatively impacting other behavior. To see this, consider how
`ScrollArea` calculates the `content_is_too_large` flag:
```rust
// This calculates a new inner rect, after painting, from the initial clip rect
let inner_rect = {
// At this point this is the available size for the inner rect.
let mut inner_size = inner_rect.size();
for d in 0..2 {
inner_size[d] = match (scroll_enabled[d], auto_shrink[d]) {
(true, true) => inner_size[d].min(content_size[d]), // shrink scroll area if content is small
(true, false) => inner_size[d], // let scroll area be larger than content; fill with blank space
(false, true) => content_size[d], // Follow the content (expand/contract to fit it).
(false, false) => inner_size[d].max(content_size[d]), // Expand to fit content
};
}
Rect::from_min_size(inner_rect.min, inner_size)
};
let outer_rect = Rect::from_min_size(inner_rect.min, inner_rect.size() + current_bar_use);
let content_is_too_large = Vec2b::new(
scroll_enabled[0] && inner_rect.width() < content_size.x,
scroll_enabled[1] && inner_rect.height() < content_size.y,
);
```
If `scroll_enabled[d] == true`, then the actual `inner_rect` (which is
calculated after painting contents) will always be smaller than the
original `inner_rect`. Hence, it is safe to unconditionally clip the
contents to `inner_rect` whenever `scroll_enabled[d] == true`.

I was having trouble with id collisions and was not able to resolve it
using `push_id` and `child_ui_with_id_source`.
When investigating the issue I found
https://github.com/emilk/egui/pull/2262 which matched the issues I had
so I forked egui and implemented the changes from that PR for the latest
version.
It solved the issue for me.
I did not notice any regressions in my project or the egui web viewer.

Hello,
I have made several corrections to stabilize the virtual keyboard on
Android and IOS (Chrome and Safari).
I don't know if these corrections can have a negative impact in certain
situations, but at the moment they don't cause me any problems.
I'll be happy to answer any questions you may have about these fixes.
These fixes correct several issues with the display of the virtual
keyboard, particularly since update 0.28, which can be reproduced on the
egui demo site.
We hope to be able to help you.
Thanks a lot for your work, I'm having a lot of fun with egui :)

This PR
- adds a pipeline to check the ios build
- removes the iOS WaitUntil workaround, which doesn't seem to be
necessary anymore after the winit update (and caused the build for iOS
to fail again because of a missing self
- ~removes a iOS workaround for window size which doesn't seem necessary
anymore~
Turns out it was still needed (but you need to actually restart the app
for the issue to show up, so I didn't catch it first)
- fixes some cargo check errors in run.rs
I've done all these changes in a single PR because otherwise the
pipeline doesn't run but I can also split them in separate PRs if that
makes it easier to review
This request focus on a TextEdit when clicked, so that touch events on
Android can now focus it.
This looks like a reasonable fix for
https://github.com/emilk/egui/issues/4941.
* Fixes#3959
There are two bugs racing each other here, which is why it sometimes
crashes and sometimes the app just silently exists
Bug 1
When the window is recreated a Destroyed event arrives (due to the Drop
of the old window). The code that receives this event does not look to
see if its the main viewport or a secondary one and unconditionally
closes the app. The code path for other platforms is slightly different
and does check.
I have moved the code that handles the destroy to be in the same place
and have the same behavior as the other platforms.
Bug 2
At recreate time the window and winit entries of the viewport are set to
None (forcin g them to be recreated). But the surface is still bound to
the old window, this causes the next context switch to fail. So I simply
added a viewport.gl_surface = None too,
This is my first egui PR so I hope I have not broken anything. If
nothing else I understand a little better how egui works.
This make the test excercise the window recreation logic, that resulted
in several bugs - see #4862
Adds a check box that turns the close button on and off for child
windows
This updates winit to 0.30.5.
https://github.com/emilk/egui/pull/4849 Had to pin the version to
0.30.2, as a Winit patch changed the behavior of selecting a theme.
Winit 0.30.5 reverts this, so we could stick with `window.theme()`, but
the newly added `ActiveEventLoop::system_theme` is more like what egui
wants anyway, as individual windows can have theme overrides.
Also bump `smithay-clipboard` to prevent some now duplicate
dependencies.
* Some initial progress towards #4490
This PR just moves `Theme` and the "follow system theme" settings to
egui and adds `RawInput.system_theme`.
A follow-up PR can then introduce the two separate `dark_mode_style` and
`light_mode_style` fields on `Options`.

Similar to #4889
Updated the `ui` method of the `Button` widget so that the alignment
given by the layout is applied to the image contained in the button (if
one exists).
Currently, only the text inside the button has alignment applied to it,
and only when it is not accompanied by an image or shortcut text. Images
within buttons are always aligned to the centre left, no matter the
alignment of the containing `Ui`. This update now also applies this
alignment to an image when it has no accompanying text, which makes
buttons with an image and no text more consistent with the appearance of
ones with text and no image.
I've also made an additional change so that the vertical alignment is
now also respected when displaying some combination of image and text,
but the original horizontal alignment remains the same, so that the
image always appears left of the text. Any shortcut text now also
follows vertical alignment, but is always horizontally aligned to the
right.
Here are some comparisons of the difference between how buttons look
with different alignments, before and after this change:

Hiya,
I need new winit for a specific fix for a android_native_actvity. There
are already two PRs, but both don't seem to have a lot of movement, or
are entirely complete:
https://github.com/emilk/egui/pull/4466
Seems to have gone stale & is missing some bits.
https://github.com/emilk/egui/pull/4702
Also seems stale (if less so), and is missing a refactor to
run_on_demand. I also *think* the accesskit integration has a mistake
and can't be enabled. I've marked them as a co-author on this as I
started from this branch. (I think! Haven't done that on git before...).
Sorry for the wall of text but just dumping some details / thoughts
here:
- There's an issue with creating child windows in winit 0.30.1 and up on
macOS. The multiple_viewports, "create immediate viewport" example
crashes on anything later 0.30.1, with a stack overflow in unsafe code.
I've create [a winit
issue](https://github.com/rust-windowing/winit/issues/3800), it *might*
already be fixed in 0.31.0 but I can't test as 0.31 will likely require
another refactoring. For now I have just pinned things to 0.30.0 exatly.
- Winit has deprecated run_on_demand, instead requiring the
ApplicationHandler interface. In 0.31.0 run_on_demand is removed. I've
refactored both the integration and the WinitApp trait to follow this
pattern. I've left user_events a bit more opaque, as it seems 0.31.0 is
doing a rework of UserEvents too.
- I've used the new lazy init approach for access kit from this branch
https://github.com/mwcampbell/egui/tree/accesskit-new-lazy-init and
marked Matt as co-author, thanks Matt!
- There was very similair but not quite the same code for run_and_return
and run_and_exit. I've merged them, but looking at the github issues
graveyard it seems vey finnicky. I *hope* this is more robust than
before but it's a bit scary.
- when receiving new_events this also used to check the redraw timing
dictionary. That doesn't seem necesarry so left this out, but that is a
slight behaviour change?
- I have reeneabled serial_windows on macOS. I wondered whether it was
fixed after this PR and does seem to be! However, even before this PR it
seems to work, so maybe winit has sorted things out before that...
Windows also works fine now without the extra hack.
- I've done a very basic test of AccessKit on Windows and screen reader
seems ok but I'm really not knowleadgable enough to say whether it's all
good or not.
- I've tested cargo tests & all examples on Windows & macOS, and ran a
basic Android app. Still, testing native platforms is wel... hard so if
anyone can test linux / iOs / older mac versions / windows 10 would
probably be a good idea!
- For consistencys sake I've made all event like functions in WinitApp
return a `Result<EventResult>`. There's quite a bit of Ok-wrapping now,
maybe too annoying? Not sure.
Thank you for having a look!

Updated the `show_content` method of the `TextEdit` widget so that the
requested text alignment (if any) is also applied to the hint text.
Currently, hint text is always aligned to the top left of the widget,
which may be inconsistent with the actual location of text entered by
the user. I think it's more intuitive for the hint text to be positioned
as if the user had entered the same text themselves.
Here are some comparisons of the difference between how the hint text
and the entered text looks, before and after this change:
