Window

There are numerous functions for querying and changing the properties of the window, for example if it is in fullscreen or how big it is in pixels.

See: window module documentation

Cursor icons

You may set the current cursor icon to use with one of these functions, it will only last for one frame, so you should re-set the cursor icon every frame.

#![allow(unused)]
fn main() {
// in frame loop/function called every frame
if is_hovered {
    use_pointer_cursor_icon();
}
}
