CustomCursor

Struct CustomCursor 

Source
pub struct CustomCursor(pub Arc<dyn CustomCursorProvider>);
Expand description

Use a custom image as a cursor (mouse pointer).

Is guaranteed to be cheap to clone.

§Platform-specific

Web: Some browsers have limits on cursor sizes usually at 128x128.

§Example

use winit_core::cursor::CustomCursorSource;

let w = 10;
let h = 10;
let rgba = vec![255; (w * h * 4) as usize];

#[cfg(not(target_family = "wasm"))]
let source = CustomCursorSource::from_rgba(rgba, w, h, w / 2, h / 2).unwrap();

#[cfg(target_family = "wasm")]
let source = CustomCursorSource::Url {
    url: String::from("http://localhost:3000/cursor.png"),
    hotspot_x: 0,
    hotspot_y: 0,
};

if let Ok(custom_cursor) = event_loop.create_custom_cursor(source) {
    window.set_cursor(custom_cursor.clone().into());
}

Tuple Fields§

§0: Arc<dyn CustomCursorProvider>

Methods from Deref<Target = dyn CustomCursorProvider>§

Source

pub fn cast_ref<T: CustomCursorProvider>(&self) -> Option<&T>

Downcast to the backend concrete type.

Returns None if the object was not from that backend.
