Struct Grid 

pub struct Grid { /* private fields */ }

A widget that arranges its children in a grid with a fixed number of columns.

Row heights are determined by the tallest child in each row; column widths by the widest child in each column. Use spacing to add a uniform gap between cells on both axes.

Implementations

impl Grid

pub fn new(columns: usize) -> Self

Create a new Grid with the given number of columns and zero spacing.

pub fn spacing(self, s: f32) -> Self

Set the gap in logical pixels between cells (applied horizontally and vertically).

pub fn layout( &self, constraints: Constraints, child_sizes: &[Size], ) -> LayoutResult

Perform the Measure + Place passes and return a LayoutResult.

child_sizes must be in the same order as children appended via ChildContainer::child / ChildContainer::children.

Emits RosaceTrace::LayoutStart and RosaceTrace::LayoutEnd events.

Trait Implementations

impl ChildContainer for Grid

fn child(self, element: impl Into<Element>) -> Self

Appends a single child element.

fn children<E: Into<Element>>(self, elements: Vec<E>) -> Self

Appends a homogeneous collection of child elements.

fn prepend(self, element: impl Into<Element>) -> Self

Inserts a child element at the front of the child list.

fn child_if(self, element: Option<impl Into<Element>>) -> Self

Appends a child element only if element is Some.

impl Clone for Grid

fn clone(&self) -> Grid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Grid

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

Formats the value using the given formatter.

impl From<Grid> for Element

fn from(g: Grid) -> Self
