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, [&window](MousePoint point){
    std::cout << std::format("Clicked on X:{} Y:{}!", MappedToPixel(point.x, window.width), MappedToPixel(point.y, window.height));
});

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);
});
