#includeIn this code example, we define a function `handleInputEvent` that will handle input events. We then register this function with the `EventMap` using the `registerEvent` method. Finally, we trigger an input event using the `triggerEvent` method. The package library that this code uses is likely an external library or framework that provides an `EventMap` implementation. It is not a standard C++ feature.#include // Define a function to handle a user input event void handleInputEvent(const Event& e) { std::cout << "Input event received!" << std::endl; } int main() { // create an EventMap to handle events EventMap eventMap; // Register the handleInputEvent function to handle input events eventMap.registerEvent("input", handleInputEvent); // Trigger an input event Event inputEvent = Event("input"); eventMap.triggerEvent(inputEvent); return 0; }
