How can i get an window bounds?

[niuhuan]

I tried get bound with get_property_value.

the println out put arr : false false false VARENUM(8197).

and

thread 'main' panicked at 'called Result::unwrap() on an Err value: Error { code: 4, message: "" }', src\main.rs:110:20

hr.get_array().unwrap();

I think it be an double* or SAFEARRAY.

I'm sorry for my poor English. I would like to know how to obtain the position and size of the top window

fn do_capture() {
// get window
    debug!("--- do capture ---");
    let foreground_window = unsafe { GetForegroundWindow() };
    debug!("foreground_window : {:?}", foreground_window);
    if foreground_window.0 == 0 {
        // todo 提示没有捕获到窗口
        return;
    }
// root element
    let ua = UIAutomation::new().unwrap();
    let handle = Handle::from(foreground_window);
    let root_element = ua.element_from_handle(handle).unwrap();
    debug!("root_element : {:?}", root_element);
// get propery
    let hr = root_element
        .get_property_value(UIA_BoundingRectanglePropertyId.into())
        .unwrap();
//
    println!(
        "arr : {} {} {} {:?}",
        hr.is_null(),
        hr.is_array(),
        hr.is_string(),
        hr.get_type(),
    );

    hr.get_array().unwrap();

    // let x: f32 = arr.get_element(0).unwrap();
    // let y: f32 = arr.get_element(1).unwrap();
    // let w: f32 = arr.get_element(2).unwrap();
    // let h: f32 = arr.get_element(3).unwrap();
    //
    // debug!("hr : {x},{y},{w},{h},");

}

I found that the Variant struct has an error when handling array types. I'll fix that in the next version.
Now, you can use get_bounding_rectangle() instead. This will return a Rect struct.

For example：

        let window = unsafe { GetForegroundWindow() };
        if window.0 == 0 {
            return;
        }

        let automation = UIAutomation::new().unwrap();
        let element = automation.element_from_handle(window.into()).unwrap();
        let rect = element.get_bounding_rectangle().unwrap();
        println!("Window Rect = {}", rect);
