* Fix incorrect max_width/height of panels
* Fix set_width/set_min_width/set_height/set_min_height
Closes https://github.com/emilk/egui/issues/647
Broke in https://github.com/emilk/egui/pull/629
* Fix expand_to_include_x/expand_to_include_y
* Make minimum grid column width propagate properly
* Expand cursor when max_rect expands
* Add ui.expand_to_include_y
* Only expand cursor in advance

* Allow using the layout cursor to restrict available area
* Avoid id clashes when putting panels inside a Ui
* Panels: Propagate height/width range to inner Ui
* Allow easy placement of panels inside of Ui:s
* demo: simplify Windows with Panels demo
* Fix case where `Plot`'s `min_auto_bounds` can be ignored after first
I ran into an issue using `Plot` within my timeline widget where if I
zoom in and out of the timeline (not the plot), the `Plot` instances
would ignore the necessary changes to the `include_x` calls and in turn
would become skewed and misaligned with the timeline below.
This changes the `Plot` to check whether or not `min_auto_bounds` have
changed and, if so, reset the memory and recalculate the bounds.
See #562 for an image of my current use case.
* Carry hidden_items when updating plot for changed bounds
* added new line styles
* update changelog
* fix#524
Add missing functions to `HLine` and `VLine`
* add functions for creating points and dashes from a line
* apply suggestions
* clippy fix
* address comments
This allows for resizaeable grids, where the last column will be given the remainder of the width.
To demonstrate, the widget gallery window is now resizeable.
* Fix margin for grid layout nested inside grid
* Minor fix for grid layout
At time of end_row, current state is finished updating row_height.
Might as well use that instead of previous state.
* Fix horizontal advancing for nested layouts in grid
* Add back horizontal layout
* Add test for nested layouts in grids
* make test table striped
* Improve table test case with slider for dynamic text
Before a disabled and enabled button would leave the parent ui
in different states, which lead to a bug where a slider drag could be
aborted if it caused a button before it to switch between enabled
and disabled.
Repro: dragging slider in "Manual Layout Test"
* Added plot items:
* Arrows, also called "Quiver plots" in matplotlib etc.
* Convex polygons
* Text
* Images
Other changes:
* Make HLine/VLine into PlotItems as well.
* Add a "fill" property to Line so that we can fill/shade the area between a line and a horizontal reference line.
* Add stems to Points, which are lines between the points and a horizontal reference line.
* Allow using .. when specifying ranges for values generated by explicit callback functions, as an alias for f64::NEG_INFINITY..f64::INFINITY
* Allow using ranges with exclusive end bounds for values generated by parametric callback functions to generate values where the first and last value are not the same.
* update changelog
* add legend background
* Use old 1.51 toolchain instead of bleeding edge
1.52 and 1.53 has problems with incremental compilation,
so some people chose to stay on 1.51 for now.
So let's make sure egui supports 1.51 for a while!
* Update to cint 0.2.2 to get rust 1.51.0 compatability
* Expanded `TextBuffer` interface to allow borrowed values.
* Removed superfluous `PartialEq` requirement on `TextBuffer`.
* Removed `std::fmt::Display` requirement for `TextBuffer`.
Now uses the `AsRef<str>` impl to format it where applicable.

* Make sure the scroll bar is never outside the screen rectangle
This is an alternative attempt to fix the bug mentioned in
https://github.com/emilk/egui/pull/392
egui expects that the container can always be made wider,
which is true for all egui Ui:s, but not true for the outer
frame/chrome that egui ultimately needs to sit within.

* Initial design for `TextBuffer` trait, to allow `TextEdit` to edit types other than `String`.
* Moved `insert_text` implementation into `TextBuffer`.
This allows the user to implement text inserting depedent on their type instead of using a `String` and converting back to `S`, which may be a lossless convertion.
* Moved part of `delete_selected_ccursor_range` implementation into `TextBuffer::delete_range`.
* `TextBuffer::insert_text` not returns how many characters were inserted into the buffer.
This allows implementations to "saturate" the buffer, only allowing for a limited length of characters to be inserted.
* Now using `byte_index_from_char_index` instead of custom implementation.
* `decrease_identation` impl now modified the string in-place.
Removed `From<String>` bound for `TextBuffer`.
* Added changes to changelog.
* Moved updated changelog to .
* Updated documentation on `TextBuffer`.

* Renamed `TextBuffer::delete_text_range` to `delete_char_range`.

* translate touch events from glium to egui
Unfortunately, winit does not seem to create _Touch_ events for the touch pad
on my mac. Only _TouchpadPressure_ events are sent.
Found some issues (like
[this](https://github.com/rust-windowing/winit/issues/54)), but I am not sure
what they exactly mean: Sometimes, touch events are mixed with
touch-to-pointer translation in the discussions.
* translate touch events from web_sys to egui
The are a few open topics:
- egui_web currently translates touch events into pointer events.
I guess this should change, such that egui itself performs this kind of
conversion.
- `pub fn egui_web::pos_from_touch_event` is a public function, but I
would like to change the return type to an `Option`. Shouldn't this
function be private, anyway?
* introduce `TouchState` and `Gesture`
InputState.touch was introduced with type `TouchState`, just as
InputState.pointer is of type `Pointer`.
The TouchState internally relies on a collection of `Gesture`s. This commit
provides the first rudimentary implementation of a Gesture, but has no
functionality, yet.
* add method InputState::zoom()
So far, the method always returns `None`, but it should work as soon as the
`Zoom` gesture is implemented.
* manage one `TouchState` per individual device
Although quite unlikely, it is still possible to connect more than one touch
device. (I have three touch pads connected to my MacBook in total, but
unfortunately `winit` sends touch events for none of them.)
We do not want to mix-up the touches from different devices.
* implement control loop for gesture detection
The basic idea is that each gesture can focus on detection logic and does not
have to care (too much) about managing touch state in general.
* streamline `Gesture` trait, simplifying impl's
* implement first version of Zoom gesture
* fix failing doctest
a simple `TODO` should be enough
* get rid of `Gesture`s
* Provide a Zoom/Rotate window in the demo app
For now, it works for two fingers only. The third finger interrupts the
gesture.
Bugs:
- Pinching in the demo window also moves the window -> Pointer events must be
ignored when touch is active
- Pinching also works when doing it outside the demo window -> it would be nice
to return the touch info in the `Response` of the painter allocation
* fix comments and non-idiomatic code
* update touch state *each frame*
* change egui_demo to use *relative* touch data
* support more than two fingers
This commit includes an improved Demo Window for egui_demo, and a complete
re-write of the gesture detection. The PR should be ready for review, soon.
* cleanup code and comments for review
* minor code simplifications
* oops – forgot the changelog

* Replace `impl Into<String>` with `impl ToString`
This is something I ran into today. Types that implement
`std::fmt::Display` cannot be passed to functions that take `impl
Into<String>`. You have to call `display_thing.to_string()`. Its a small
thing but would be fixed by instead taking `impl ToString`.
Afaik `impl ToString` is a superset of `impl Into<String>`, unless users
manually implement `Into<String> for T` (or `From<T> for String`) for
their own types. However I think its more common to implement `Display`
as that works with `println` and friends. The main difference is that
`Display::fmt` can return errors but thats also quite rare in my
experience.
I did some testing in a [playground] and seems to work.
[playground]: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=1111e071f6ae416ae2688d58d2e9b575
* Silence warnings
This adds a new `zoom_delta` to input.
This is hooked up to ctrl-scroll on egui_web and egui_glium.
Browsers convert trackpad pinch gestures to ctrl-scroll,
so this means you can not pinch-to-zoom plots (on trackpad).
In the future we can support multitouch pinch-to-zoom via the same
`InputState::zoom_factor()` function
* drag and zoom support for plots
* update doctest
* use impl ToString
* revert back to Into<String> until #302 is solved

* Display ResizeHorizontal cursor on hover
* Adapt the URL open command to the platform
With this new version we use $OSTYPE bash env var to query what OS
are we running on.
- On Linux, ex: Fedora, we use `xdg-open`
- On Windows, ex: msys, we use `start`
- For other other variants we try to use `open`
We should update this script when we notice that `open` is not
available on a particular platform.
(cherry picked from commit b3aa4982f683d961c21fd18e9ffc1fdf5fba0783)
* Add slow speed mode for `DragValue`
The slow speed mode is disabled by default. It can be activated
or deactivated using `DragValue::slow_speed()`.
When active the `Shift` key can be used to have a better control
over the value, `DragValue::speed` / 10.0 increments.
* Display `ResizeHorizontal` cursor while dragging too
* Apply review suggestion
Shorter and in line with the rest of the code base
Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>
* Add `Modifiers::shift_only` for better code clarity
* Make slow speed always enabled

* egui_web: enable IME support on web.
* Move candidate window following text cursor.
* Preclude too frequent agent movement.
* IME candidate window move on native app.
This enables functions that return `impl Widget`, so that you can
create a widget by just returning a lambda from a function.
For instance: `ui.add(toggle(bool))` (instead of `toggle(ui, bool)`)
