Struct ButtonMatrix 

pub struct ButtonMatrix<W, H>
where
    W: ArrayLength,
    H: ArrayLength,
{ /* private fields */ }

A matrix of buttons.

This struct represents a matrix of buttons in the view system. It is parameterized by the width and height of the matrix.

Implementations

impl<W, H> ButtonMatrix<W, H>

where W: ArrayLength, H: ArrayLength,

pub fn new() -> Self

Create a new button matrix.

pub fn get_button_by_index(&self, index: usize) -> Option<&Button>

Get a button by index.

This method returns a reference to the button at the given index. The index is calculated as y * width + x.

pub fn get_button(&self, x: usize, y: usize) -> Option<&Button>

Get a button by coordinates.

This method returns a reference to the button at the given coordinates.

pub fn set_button( &mut self, x: usize, y: usize, button: Button, ) -> Result<(), Box<dyn Error>>

Set a button by coordinates.

This method sets the button at the given coordinates.

pub fn set_button_by_index( &mut self, index: usize, button: Button, ) -> Result<(), Box<dyn Error>>

Set a button by index.

This method sets the button at the given index. The index is calculated as y * width + x.

pub fn width(&self) -> usize

Get the width of the matrix.

pub fn height(&self) -> usize

Get the height of the matrix.

pub fn size(&self) -> usize

Get the total number of buttons in the matrix.

Trait Implementations

impl<W, H> Default for ButtonMatrix<W, H>

where W: ArrayLength, H: ArrayLength,

fn default() -> Self

Returns the “default value” for a type.
