# Changelog
# Next version (0.11.2)
### API updates
- Bring back `Cursive::set_fps` for <30Hz refresh rates.
- Add `Cursive::backend_name` to get the name of the current backend.
- Add a new backend based on the crossterm library.
- Add direct downcast methods to `dyn AnyView`
- Add sort methods to `SelectView`
### Improvements
- Improved printer performance with styled spans.
## 0.11.1
### API updates
- Added manual scrolling methods to `view::scroll::Core`:
- `keep_in_view`, `scroll_to`, `scroll_to_x`, `scroll_to_y`
Note: the `view::scroll` module is hidden behind an experimental
feature `unstable_scroll`.
### Improvements
- Improved printer performance (thanks to @chrisvest).
### Bugfixes
- Fixed `MenuPopup` borders near delimiters.
## 0.11.0
### Breaking changes
- `Cursive::{ncurses, pancurses, termion}` now return
`io::Result<Self>` instead of panicking. `Cursive::default()` still unwraps.
- Also added `Cursive::try_new` for failible backends.
- Replaced `set_fps(i32)` with `set_autorefresh(bool)`
- `Finder::find_id()` is renamed to `call_on_id()`, and a proper
`find_id()` was added instead.
- Updated the Backend trait for a simpler input system
- Updated to Rust 2018 edition (now requires rustc > 1.31)
- `Cursive::clear()` now takes `&mut self`
### API updates
- Add a logging implementation (`logger::init()`) and a `DebugConsole`
(`cursive::toggle_debug_console()`)
- Add user-data to Cursive.
- `Cursive::set_user_data()` can store some user-defined data structure.
- `Cursive::user_data()` and `Cursive::with_user_data()` can be used to
access the data.
- Add `StackView::remove_layer()`
- Add `CircularFocus` view (and bring proper circular focus to dialogs)
- Add `HideableView::is_visible()`
- Add `type CbSink = Sender<Box<CbFunc>>` as an alias for the return type of
`Cursive::cb_sink()`
- Add `LinearLayout::{insert_child, swap_children, set_weight}` for more
in-place modifications.
- Add `Printer::{cropped_centered,shrinked_centered}`
### Improvements
- Updated termion backend to use direct /dev/tty access for improved performance.
- Enabled raw mode for ncurses and pancurses. Among other improvements, this
lets applications receive Ctrl+S and Ctrl+Q events.
### Bugfixes
- Fixed overflow check for titles in `Dialog` and `Panel`
## 0.10.0
### New features
- Add `EventTrigger` and update `OnEventView` to use it.
- Breaking change: "inner" callbacks for OnEventView now take the event as
extra argument.
- Add `Printer::enabled` and `EnableableView` to disable whole subtrees.
- Add `RadioGroup::on_change` to set a callback on selection change.
- `SelectView` now uses `StyledString` to display colored text.
- Add `PaddedView` to add padding to any view.
- Update dependencies
- Breaking change: crossbeam-channel was updated, and using `send()` now
returns a `Result`.
### Bugfixes
- Fix mouse events on Ubuntu
### Doc
- Added examples to most utility types (`XY`, `Vec2`, ...)
## 0.9.2
### New features
- Add an optional title to `Panel`
- Add `immut1!`, `immut2!` and `immut3!` macros to wrap a `FnMut` in `Fn`
- SelectView: autojump is now opt-in (jump to an element after a letter is pressed)
### Bugfixes
- Fix possible crash with `ListView` and `SelectView` in very small spaces
- Fix termion backend compilation on non-unix platforms
## 0.9.1
### New features
- Add `Cursive::on_event` to send simulated events.
- Add `EventResult::and` to combine callbacks.
- Allow custom color in `ProgressBar`.
### Bugfixes
- LinearLayout:
- Better geometry computation with constrained size
- Fixed cache invalidation
- Fix possible panic when removing children
- ScrollView:
- Fix possible panic with full-height scrollbar
- Fix possible panic with empty content
- Fix cache
- Fix menubar focus after action
## Doc
- Fix Readme and examples with `Cursive::default()`
## 0.9.0
### New features
- Cursive now supports third-party backends
- Add generic `ScrollView` wrapper. Removes internal scrolling behaviour from
`TextView`.
- Callbacks sent through `Cursive::cb_sink()` are now processed instantly,
without the need for `set_fps`.
- Make backend a dynamic choice
- User must select a backend in `Cursive::new`
- 3rd party libraries do not need to play with backend features anymore
- Move from `chan` and `chan-signals` to `crossbeam-channel` and `signal-hook`
- Batch-process events for higher performance
- Add `StackView::find_layer_from_id`
- Add `SelectView::insert_item`
- Add `TextArea::{enable, disable}`
- Reworked `AnyView`
- `SelectView`: Fix mouse events
- Return callbacks from manual control methods
- `SelectView::{set_selection, select_up, select_down, remove_item}`
- `EditView::{set_content, insert, remove}`
- Add `rect::Rect`
- Add `HideableView`
### Changes
- Replaced `Cursive::new()` with `Cursive::default()`
- Renamed `Vec4` to `Margins`
- `Callbacks` cannot be created from functions that return a value
- The returned value used to be completely ignored
- `AnyView` does not extend `View` anymore (instead, `View` extends `AnyView`)
- If you were using `AnyView` before, you probably need to replace it with `View`
- Scrolling is now added to a view with `.scrollable()`
- `cb_sink` is now a `crossbeam_channel::Sender` instead of `chan::Sender`
- `SelectView::selection` now returns an `Option<Rc<T>>` instead of just `Rc<T>`.
It will return `None` if the `SelectView` is empty.

### Bugfixes
