HelloInput Example

Description

This example demonstrates how to handle basic input events by:

• Create a window using WindowWaylandWayland
• Register event listeners using EventListener<T> for:
  • Mouse click events
  • Specific key events
  • General keypress events
• Print formatted feedback to the console when events are triggered

Expected Result

When you interact with the window, you might see console output like:

Clicked on X:450 Y:320! Pressed specifically the a key! Pressed the b key!

Make sure that the window has focus.

Highlighted Code Snippet

EventListener<MousePoint> clickListener(&window.onMouseLeftClick, [](MousePoint point){
    std::cout << std::format("Clicked on X:{} Y:{}!", point.x, point.y);
});

EventListener<void> keyAListener(&window.onKeyDown['a'], [](){
    std::cout << std::format("Pressed specifically the a key!");
});

EventListener<char> anyKeyListener(&window.onAnyKeyDown, [](char key){
    std::cout << std::format("Pressed the {} key!", key);
});
