Rust for windows uiautomation

uiatomation-rs包是一套windows自动化体系的封装包，可以辅助你快速进行Windows自动化程序的开发。

使用

使用时将对本包的依赖行加入到Cargo.toml文件中。你可以直接使用封装好的API进行操作。

示例程序

打印所有界面元素

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(())
}

打开记事本并模拟写入文本

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();
    }
}

支持Variant类型属性操作

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);
}

模拟键盘输入

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();
}

添加事件侦听接口

struct MyFocusChangedEventHandler{}

impl CustomFocusChangedEventHandler for MyFocusChangedEventHandler {
    fn handle(&self, sender: &uiautomation::UIElement) -> uiautomation::Result<()> {
        println!("Focus changed: {}", sender);
        Ok(())
    }
}

fn main() {
    let note_proc = 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() {
        let focus_changed_handler = MyFocusChangedEventHandler {};
        let focus_changed_handler = UIFocusChangedEventHandler::from(focus_changed_handler);

        automation.add_focus_changed_event_handler(None, &focus_changed_handler).unwrap();

        let text_changed_handler: Box<CustomPropertyChangedEventHandlerFn> = Box::new(|sender, property, value| {
            println!("Property changed: {}.{:?} = {}", sender, property, value);
            Ok(())
        });
        let text_changed_handler = UIPropertyChangedEventHandler::from(text_changed_handler);

        automation.add_property_changed_event_handler(&notepad, uiautomation::types::TreeScope::Subtree, None, &text_changed_handler, &[UIProperty::ValueValue]).unwrap();
    }

    println!("waiting for notepad.exe...");
    note_proc.wait().unwrap();
}
