# 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
```cpp
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);
});
```
## How to Run
```bash
crafter-build -c example -r
```
