Getting started

Mateu lets you define UIs using plain Java.

A minimal example

@UI("")
public class Counter {

  @ReadOnly
  int count = 0;

  @Button
  Runnable increment = () -> count++;

}

This defines a working UI.

Actions

Actions can be defined in multiple ways:

• as Runnable fields
• as methods annotated with @Toolbar
• as methods annotated with @Button

This gives you flexibility in how actions are rendered and positioned.
