- Refactor the `table` module for better top to bottom readability by
putting types first and arranging them in a logical order (Table, Row,
Cell, other).
- Adds new methods for:
- `Table::rows`
- `Row::cells`
- `Cell::new`
- `Cell::content`
- `TableState::new`
- `TableState::selected_mut`
- Makes `HighlightSpacing::should_add` pub(crate) since it's an internal
detail.
- Adds tests for all the new methods and simple property tests for all
the other setter methods.
Adds helper methods that convert from iterators of u16 values to the
specific Constraint type. This makes it easy to create constraints like:
```rust
// a fixed layout
let constraints = Constraint::from_lengths([10, 20, 10]);
// a centered layout
let constraints = Constraint::from_ratios([(1, 4), (1, 2), (1, 4)]);
let constraints = Constraint::from_percentages([25, 50, 25]);
// a centered layout with a minimum size
let constraints = Constraint::from_mins([0, 100, 0]);
// a sidebar / main layout with maximum sizes
let constraints = Constraint::from_maxes([30, 200]);
```
The previous name `start_corner` did not communicate clearly the intent of the method.
A new method `direction` and a new enum `ListDirection` were added.
`start_corner` is now deprecated
Structs and enums at the top of the file helps show the interaction
between the types without having to find each type in between longer
impl sections.
Also moved the try_split function into the Layout impl as an associated
function and inlined the `layout::split()` which just called try_split.
This makes the code a bit more contained.
This allows to build list like
```
List::new(["Item 1", "Item 2"])
```
BREAKING CHANGE: `List::new` parameter type changed from `Into<Vec<ListItem<'a>>>`
to `IntoIterator<Item = Into<ListItem<'a>>>`
Fixes#650
This PR corrects the "builder methods" expressing to simple `setters`
(see #650#655), and gives a clearer diagnostic notice on setters `must_use`.
`#[must_use = "method moves the value of self and returns the modified value"]`
Details:
docs: Correct wording in docs from builder methods
Add `must_use` on layout setters
chore: add `must_use` on widgets fluent methods
This commit ignored `table.rs` because it is included in other PRs.
test(gauge): fix test
This prevents creating a table that doesn't actually render anything.
Fixes: https://github.com/ratatui-org/ratatui/issues/537
BREAKING CHANGE: Table::new() now takes an additional widths parameter.
It controls how to distribute extra space to an underconstrained table.
The default, legacy behavior is to leave the extra space unused. The
new options are LastTakesRemainder which gets all space to the rightmost
column that can used it, and EvenDistribution which divides it amongst
all columns.
Fixes#370
Layout and Table now accept IntoIterator for constraints with an Item
that is AsRef<Constraint>. This allows pretty much any collection of
constraints to be passed to the layout functions including arrays,
vectors, slices, and iterators (without having to call collect() on
them).
Previously the default highlight_style was set to `Style::default()`,
which meant that the highlight style was the same as the normal style.
This change sets the default highlight_style to reversed text.
BREAKING CHANGE: The `Tab` widget now renders the highlight style as
reversed text by default. This can be changed by setting the
`highlight_style` field of the `Tab` widget.
The Tab widget now contains padding_left and and padding_right
properties. Those values can be set with functions `padding_left()`,
`padding_right()`, and `padding()` whic all accept `Into<Line>`.
Fixes issue https://github.com/ratatui-org/ratatui/issues/502
Previously, when computing the inner rendering area of a block, all
titles were assumed to be positioned at the top, which caused the
height of the inner area to be miscalculated.
The layout split will generally fill the remaining area when `split()`
is called. This change allows the caller to configure how any extra
space is allocated to the `Rect`s. This is useful for cases where the
caller wants to have a fixed size for one of the `Rect`s, and have the
other `Rect`s fill the remaining space.
For now, the method and enum are marked as unstable because the exact
name is still being bikeshedded. To enable this functionality, add the
`unstable-segment-size` feature flag in your `Cargo.toml`.
To configure the layout to fill the remaining space evenly, use
`Layout::segment_size(SegmentSize::EvenDistribution)`. The default
behavior is `SegmentSize::LastTakesRemainder`, which gives the last
segment the remaining space. `SegmentSize::None` will disable this
behavior. See the docs for `Layout::segment_size()` and
`layout::SegmentSize` for more information.
Fixes https://github.com/ratatui-org/ratatui/issues/536
The offset method creates a new Rect that is moved by the amount
specified in the x and y direction. These values can be positive or
negative. This is useful for manual layout tasks.
```rust
let rect = area.offset(Offset { x: 10, y -10 });
```
Adds a convenience function to create a layout with a direction and a
list of constraints which are the most common parameters that would be
generally configured using the builder pattern. The constraints can be
passed in as any iterator of constraints.
```rust
let layout = Layout::new(Direction::Horizontal, [
Constraint::Percentage(50),
Constraint::Percentage(50),
]);
```
BREAKING CHANGE:
Layout::new() now takes a direction and a list of constraints instead of
no arguments. This is a breaking change because it changes the signature
of the function. Layout::new() is also no longer const because it takes
an iterator of constraints.
