feat: list window in z order

Work seamlessly on Windows @louis030195 👍

[nashaofu]

The implementation method on macOS is incorrect, which can lead to multiple windows being in a focused state simultaneously.
The following code can obtain the currently focused application, but it cannot accurately obtain the window.

use cocoa::base::{id, nil};
use cocoa::foundation::NSString;
use objc::{class, msg_send, sel, sel_impl};

fn main() {
    unsafe {
        // 获取 NSWorkspace 类的实例
        let workspace: id = msg_send![class!(NSWorkspace), sharedWorkspace];
        
        // 获取当前前台应用
        let front_app: id = msg_send![workspace, frontmostApplication];

        println!("front_app {:?}", front_app);

        if front_app != nil {
            let app_name: id = msg_send![front_app, localizedName];
            let app_name_str = NSString::UTF8String(app_name);
            println!("当前聚焦的应用程序: {}", std::ffi::CStr::from_ptr(app_name_str).to_str().unwrap());
        } else {
            println!("无法获取当前聚焦的应用程序。");
        }
    }
}

isnt window inside apps anyway?

isnt window inside apps anyway?

An application may have multiple windows, but the system can only identify which application is currently in focus, not the specific window within that application that is focused.

However, I am confident that there are other methods to obtain this information. For instance, Electron can retrieve it.

[nashaofu]

MacOS can get a relatively accurate Focused window, but there are still some problems. For example, if an application has multiple windows and one of them is set to always stay on top, switching to another window within the same application may still retrieve information about the window that is always on top. To obtain accurate information about the focused window, accessibility permissions are likely required.

f I return the window hierarchy, is the is_focused status no longer needed?

@louis030195 The return value of window::all() is already sorted by window hierarchy from top to bottom, and window.z() has been added.

use std::thread;
use xcap::Window;

fn main() {
    thread::sleep(std::time::Duration::from_secs(3));

    let windows = Window::all().unwrap();

    for window in windows.clone() {
        println!(
            "Window:\n id: {}\n title: {}\n app_name: {}\n pid: {}\n monitor: {:?}\n position: {:?}\n size {:?}\n state {:?}\n",
            window.id(),
            window.title(),
            window.app_name(),
            window.pid(),
            window.current_monitor().name(),
            (window.x(), window.y(), window.z()),
            (window.width(), window.height()),
            (window.is_minimized(), window.is_maximized())
        );
    }
}

that's cool!

what happen in these situations:

• macos, single monitor, one full screen app, one app on top of it
• macos, single monitor, same app but multiple windows at different level on z:

- macos, 2 monitors, 2 app full screen - etc. i don't remember behaviour on windows/linux

[nashaofu]

The results of these three test cases are in line with expectations. However, in macOS, the z-axis values of multiple windows may be identical, whereas in Linux and Windows, they are different. Do you wish for consistency across all platforms?

macos, single monitor, one full screen app, one app on top of it

Window:

macos, single monitor, same app but multiple windows at different level on z:

The upper level window z is larger

macos, 2 monitors, 2 app full screen - etc. i don't remember behaviour on windows/linux

The activated window level is higher，Electron is actived.

After consideration, the Z value will still remain unique, just like in Windows and Linux.

@nashaofu fyi this does not work on macos

minimized / maximized is always false and z is showing 0 even though it's in the background
