Struct Grid 

pub struct Grid { /* private fields */ }

Grid widget: a fixed number of equal-width columns.

Implementations

impl Grid

pub fn new(columns: usize) -> Self

Create an empty grid with columns columns (0 is stored as 1).

pub fn columns(self, columns: usize) -> Self

Set the number of columns (0 is stored as 1).

pub fn gap(self, gap: f32) -> Self

Set the gap between cells. A gap that is not finite or is negative is treated as 0.

pub fn row_height(self, height: f32) -> Self

Set a fixed row height. A negative or non-finite height clears it, so the rows share the available height equally.

pub fn child(self, widget: impl Widget + 'static) -> Self

Add a child widget; it takes the next free cell.

pub fn with_test_id(self, id: impl Into<String>) -> Self

Set test ID.

pub fn get_columns(&self) -> usize

Number of columns.

pub fn get_gap(&self) -> f32

The gap in use (0 when the stored gap is not finite or is negative).

pub fn get_row_height(&self) -> Option<f32>

The fixed row height, if one is set.

pub fn row_count(&self) -> usize

Number of rows needed for the current children.

pub fn cells(&self, bounds: Rect) -> Vec<Rect>

The cell of each child for the given bounds.
