Struct winit::window::CustomCursor
source · pub struct CustomCursor {
pub(crate) inner: PlatformCustomCursor,
}
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::window::CustomCursor;
let w = 10;
let h = 10;
let rgba = vec![255; (w * h * 4) as usize];
#[cfg(not(target_family = "wasm"))]
let source = CustomCursor::from_rgba(rgba, w, h, w / 2, h / 2).unwrap();
#[cfg(target_family = "wasm")]
let source = {
use winit::platform::web::CustomCursorExtWebSys;
CustomCursor::from_url(String::from("http://localhost:3000/cursor.png"), 0, 0)
};
let custom_cursor = event_loop.create_custom_cursor(source);
window.set_cursor(custom_cursor.clone());
Fields§
§inner: PlatformCustomCursor
Platforms should make sure this is cheap to clone.
