Struct WindowContainer

pub struct WindowContainer {
    pub bg_color: u32,
    /* private fields */
}

Contains a Window, pixel buffer, and properties.

Fields

bg_color: u32

Implementations

impl WindowContainer

pub fn new( width: usize, height: usize, name: &str, color: &str, ) -> Result<Self, WinErr>

Initalizes a new WindowContainer.

pub fn update(&mut self) -> Result<(), WinErr>

Updates the window with its pixel buffer. Pressing ESC will gracefully exit the program.

let mut window = window!(?500, 500, "Window", "FFFFFF");

loop {//can close by pressing ESC
    window.update();
}

pub fn clear(&mut self)

clears the screen to the background color.

let mut window = window!(?500, 500, "Window", "FF00FF");
 
loop {
    window.clear();//clears to "FF00FF"
 
    //drawing code
 
    window.update();
}

pub fn get(&self, pos: (usize, usize)) -> Result<String, WinErr>

Returns the hexidecimal value of a pixel at a position.

pub fn set(&mut self, pos: (usize, usize), val: &str) -> Result<(), WinErr>

Sets a pixel to a hexidecimal value.

pub fn iter(&self) -> IntoIter<(String, (usize, usize))>

returns an iterator over the pixel buffer, holding the hex value and position. Note that the iterator pulled from the buffer is no longer linked to the window, and modifying it will do nothing.

let window = window!(?500, 500, "Window", "FFFFFF");

for (val, pos) in window.iter() {
    let r = to_hex2(pos.0 as u8).unwrap();
    let g = to_hex2(pos.1 as u8).unwrap();
    let string = format!("{r}{g}00");

    window.set(pos, &string)?;
}

loop {
    window.update();
}

pub fn circle( &mut self, pos: (usize, usize), r: usize, color: &str, ) -> Result<(), WinErr>

Draws a circle at a given position with a radius and color.

pub fn line( &mut self, p1: (usize, usize), p2: (usize, usize), t: f64, color: &str, ) -> Result<(), WinErr>

Draws a line between 2 points, with a thickness and color.
