Struct Popover 

pub struct Popover {
    pub anchor: Rect,
    pub placement: Placement,
    pub width: Option<u16>,
    pub max_height: Option<u16>,
    pub bordered: bool,
    pub gap: u16,
    pub auto_flip: bool,
}

Configuration for a popover widget.

Fields

anchor: Rect

The anchor rectangle to position relative to.

placement: Placement

Preferred placement direction.

width: Option<u16>

Desired width of the popover content area. If None, uses anchor width.

max_height: Option<u16>

Maximum height of the popover. If None, fills available space.

bordered: bool

Whether to draw a border around the popover.

gap: u16

Gap between anchor and popover (in cells).

auto_flip: bool

Whether to auto-flip when there isn’t enough space.

Implementations

impl Popover

pub fn new(anchor: Rect, placement: Placement) -> Self

Create a popover anchored to the given rectangle.

pub fn width(self, w: u16) -> Self

Set the desired width.

pub fn max_height(self, h: u16) -> Self

Set the maximum height.

pub fn with_border(self, bordered: bool) -> Self

Enable or disable the border.

pub fn gap(self, gap: u16) -> Self

Set the gap between anchor and popover.

pub fn auto_flip(self, flip: bool) -> Self

Enable or disable auto-flip.

pub fn compute_area(&self, viewport: Rect) -> Option<Rect>

Compute the content area for this popover within the given viewport.

Returns the Rect where content should be rendered, accounting for placement, flip logic, and viewport bounds. Returns None if the popover cannot fit at all.

pub fn render_with<F>( &self, viewport: Rect, frame: &mut Frame<'_>, render_content: F, )

where F: FnOnce(Rect, &mut Frame<'_>),

Render the popover border (if enabled) and invoke the callback for content.

The callback receives the inner content area (inside the border if any).

Trait Implementations

impl Clone for Popover

fn clone(&self) -> Popover

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Popover

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
