Rust for windows uiautomation

The uiatomation-rs crate is a wrapper for windows uiautomation. This crate can help you make windows uiautoamtion API calls conveniently.

Usages

Start by adding the dependency of this crate to your Cargo.toml file. Make use of any windows uiautomation calls as needed.

Examples

Print All UIElements

use uiautomation::Result;
use uiautomation::UIAutomation;
use uiautomation::UIElement;
use uiautomation::UITreeWalker;

fn main() {
    let automation = UIAutomation::new().unwrap();
    let walker = automation.get_control_view_walker().unwrap();
    let root = automation.get_root_element().unwrap();

    print_element(&walker, &root, 0).unwrap();
}

fn print_element(walker: &UITreeWalker, element: &UIElement, level: usize) -> Result<()> {
    for _ in 0..level {
        print!(" ")
    }
    println!("{} - {}", element.get_classname()?, element.get_name()?);

    if let Ok(child) = walker.get_first_child(&element) {
        print_element(walker, &child, level + 1)?;

        let mut next = child;
        while let Ok(sibling) = walker.get_next_sibling(&next) {
            print_element(walker, &sibling, level + 1)?;

            next = sibling;
        }
    }
    
    Ok(())
}

Open Notepad and Input Text

use uiautomation::core::UIAutomation;
use uiautomation::processes::Process;

fn main() {
    Process::create("notepad.exe").unwrap();

    let automation = UIAutomation::new().unwrap();
    let root = automation.get_root_element().unwrap();
    let matcher = automation.create_matcher().from(root).timeout(10000).classname("Notepad");
    if let Ok(notepad) = matcher.find_first() {
        println!("Found: {} - {}", notepad.get_name().unwrap(), notepad.get_classname().unwrap());

        notepad.send_keys("Hello,Rust UIAutomation!{enter}", 10).unwrap();

        let window: WindowControl = notepad.try_into().unwrap();
        window.maximize().unwrap();
    }
}

Get Properties As Variant

use uiautomation::UIAutomation;
use uiautomation::types::UIProperty;
use uiautomation::variants::Variant;

fn main() {
    let automation = UIAutomation::new().unwrap();
    let root = automation.get_root_element().unwrap();

    let name: Variant = root.get_property_value(UIProperty::Name).unwrap();
    println!("name = {}", name.get_string().unwrap());

    let ctrl_type: Variant = root.get_property_value(UIProperty::ControlType).unwrap();
    let ctrl_type_id: i32 = ctrl_type.try_into().unwrap();
    println!("control type = {}", ctrl_type_id);

    let enabled: Variant = root.get_property_value(UIProperty::IsEnabled).unwrap();
    let enabled_str: String = enabled.try_into().unwrap();
    println!("enabled = {}", enabled_str);
}

Simulate Keyboard Input

use uiautomation::core::UIAutomation;

fn main() {
    let automation = UIAutomation::new().unwrap();
    let root = automation.get_root_element().unwrap();
    root.send_keys("{Win}D", 10).unwrap();
}
