Struct Frame

Source 
pub struct Frame<'a> { /* private fields */ }
Expand description

A consistent view into the terminal state for rendering a single frame.

This is obtained via the closure argument of Terminal::draw. It is used to render widgets to the terminal and control the cursor position.

The changes drawn to the frame are applied only to the current Buffer. After the closure returns, the current buffer is compared to the previous buffer and only the changes are applied to the terminal. This avoids drawing redundant cells.

Implementations§

Source§

impl Frame<'_>

Source

pub const fn area(&self) -> Rect

The area of the current frame

This is guaranteed not to change during rendering, so may be called multiple times.

If your app listens for a resize event from the backend, it should ignore the values from the event for any calculations that are used to render the current frame and use this value instead as this is the area of the buffer that is used to render the current frame.

pub const fn size(&self) -> Rect

👎Deprecated: use .area() as it’s the more correct name

The area of the current frame

This is guaranteed not to change during rendering, so may be called multiple times.

pub fn render_widget<W: Widget>(&mut self, widget: W, area: Rect)

Render a Widget to the current buffer using Widget::render.

Usually the area argument is the size of the current frame or a sub-area of the current frame (which can be obtained using Layout to split the total area).

§Example
use ratatui::{layout::Rect, widgets::Block};

let block = Block::new();
let area = Rect::new(0, 0, 5, 5);
frame.render_widget(block, area);

pub fn render_widget_ref<W: WidgetRef>(&mut self, widget: W, area: Rect)

Available on crate feature unstable-widget-ref only.

Render a WidgetRef to the current buffer using WidgetRef::render_ref.

Usually the area argument is the size of the current frame or a sub-area of the current frame (which can be obtained using [Layout] to split the total area).

§Example
use ratatui::{layout::Rect, widgets::Block};

let block = Block::new();
let area = Rect::new(0, 0, 5, 5);
frame.render_widget_ref(block, area);
§Availability

This API is marked as unstable and is only available when the unstable-widget-ref crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Source

pub fn render_stateful_widget<W>( &mut self, widget: W, area: Rect, state: &mut W::State, )
where W: StatefulWidget,

Render a StatefulWidget to the current buffer using StatefulWidget::render.

Usually the area argument is the size of the current frame or a sub-area of the current frame (which can be obtained using Layout to split the total area).

The last argument should be an instance of the StatefulWidget::State associated to the given StatefulWidget.

§Example
use ratatui::{
    layout::Rect,
    widgets::{List, ListItem, ListState},
};

let mut state = ListState::default().with_selected(Some(1));
let list = List::new(vec![ListItem::new("Item 1"), ListItem::new("Item 2")]);
let area = Rect::new(0, 0, 5, 5);
frame.render_stateful_widget(list, area, &mut state);

pub fn render_stateful_widget_ref<W>( &mut self, widget: W, area: Rect, state: &mut W::State, )
where W: StatefulWidgetRef,

Available on crate feature unstable-widget-ref only.

Render a StatefulWidgetRef to the current buffer using StatefulWidgetRef::render_ref.

Usually the area argument is the size of the current frame or a sub-area of the current frame (which can be obtained using [Layout] to split the total area).

The last argument should be an instance of the StatefulWidgetRef::State associated to the given StatefulWidgetRef.

§Example
use ratatui::{
    layout::Rect,
    widgets::{List, ListItem, ListState},
};

let mut state = ListState::default().with_selected(Some(1));
let list = List::new(vec![ListItem::new("Item 1"), ListItem::new("Item 2")]);
let area = Rect::new(0, 0, 5, 5);
frame.render_stateful_widget_ref(list, area, &mut state);
§Availability

This API is marked as unstable and is only available when the unstable-widget-ref crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

pub fn set_cursor_position<P: Into<Position>>(&mut self, position: P)

After drawing this frame, make the cursor visible and put it at the specified (x, y) coordinates. If this method is not called, the cursor will be hidden.

Note that this will interfere with calls to Terminal::hide_cursor, Terminal::show_cursor, and Terminal::set_cursor_position. Pick one of the APIs and stick with it.

pub const fn count(&self) -> usize

Returns the current frame count.

This method provides access to the frame count, which is a sequence number indicating how many frames have been rendered up to (but not including) this one. It can be used for purposes such as animation, performance tracking, or debugging.

Each time a frame has been rendered, this count is incremented, providing a consistent way to reference the order and number of frames processed by the terminal. When count reaches its maximum value (usize::MAX), it wraps around to zero.

This count is particularly useful when dealing with dynamic content or animations where the state of the display changes over time. By tracking the frame count, developers can synchronize updates or changes to the content with the rendering process.

§Examples
let current_count = frame.count();
println!("Current frame count: {}", current_count);
