Implementations§

Source§

impl CanvasWidget

Source

pub fn new(x: i32, y: i32, width: u32, height: u32) -> Rc<RefCell<Self>>

§Description

Creates a new canvas widget

§Arguments
  • x: i32 - The x position of the widget
  • y: i32 - The y position of the widget
  • width: u32 - The width of the widget
  • height: u32 - The height of the widget
Source

pub fn get_width(&self) -> u32

§Description

Retrieves the width of the canvas

§Returns

u32 - The width of the canvas

Source

pub fn get_height(&self) -> u32

§Description

Retrieves the height of the display buffer

§Returns

u32 - The height of the display buffer

Source

pub fn set_char(&mut self, c: char, x: i32, y: i32)

§Description

Draws a character to the canvas

If the coordinates are out of the bounds of the canvas it ignores the write

§Arguments

  • x: u32 - The x position to write to
  • y: u32 - The y position to write to
Source

pub fn clear(&mut self, c: char)

§Description

Clears the canvas to a specified character

§Arguments
  • c: char - The character to clear with
