active-win-pos-rs

A small Rust library that lets you get position, size, title and a few other properties of the active window on Windows, MacOS and Linux

Usage

Add to Cargo.toml:

[dependencies]
active-win-pos-rs = "0.8"

Use:

use active_win_pos_rs::get_active_window;

fn main() {
    match get_active_window() {
        Ok(active_window) => {
            println!("active window: {:#?}", active_window);
        },
        Err(()) => {
            println!("error occurred while getting the active window");
        }
    }
}

Would give you an instance of ActiveWindow struct with unique window id, process id, window position and window title.

Or use active_win_pos_rs::get_position to get the WindowPosition only.

Window title on MacOS

On MacOS title property will always return an empty string unless you Enable Screen Recording permission for your app.
