FastUIA — Native Windows UI Automation API for Java

High-performance, native Windows UI Automation (UIA) for Java.

FastUIA provides real-time native UI Automation for Java applications without the overhead of heavy frameworks.

// Quick Start — Example
import fastuia.FastUIA;
import fastuia.FastUIAElement;

public class Demo {
    public static void main(String[] args) {
        FastUIA uia = new FastUIA();
        
        // Get focused element
        FastUIAElement el = uia.getFocusedElement();
        
        if (el != null) {
            System.out.println("Focused: " + el.getName());
            System.out.println("Type:    " + el.getControlType());
            
            if (el.supportsValue()) {
                System.out.println("Value: " + el.getValue());
            }
        }
    }
}

Key Features

• 🚀 Native Performance — Direct UI Automation API access via JNI.
• ⚡ Zero Overhead — No polling, purely event-driven callbacks.
• 📦 Zero Dependencies — Just requires Java 17+ and Windows.
• 🎯 Object-Oriented — Clean, type-safe API for elements and patterns.

Performance

FastJava modules require two dependencies: the module itself, and FastCore (which handles the cross-platform native library extraction).
