Detailed Description

Base class for all event-receiving traits.

EventReceiver is the storage layer shared by every trait that handles events (Clickable, Hoverable, Keyable, etc.). It maintains a map of string keys to callback vectors, where each key is produced by EnumKey::get() from any ml::Event or manifest event enum value.

Framework dispatchers call process() to invoke stored callbacks. Traits call getCallbacks() to register them. User code interacts with EventReceiver only indirectly through the trait convenience methods (onClick, onHover, onUpdate, etc.).

Member Function Documentation

◆ process() [1/2]

virtual void ml::EventReceiver::process	(	const std::string &	key,
		const std::optional< sf::Event > &	event )

virtual

Invoke all callbacks registered for key.

Called by framework dispatchers. key is the string produced by EnumKey::get(eventEnum).

Parameters

key	String key identifying the event.
event	SFML event forwarded to each callback.

◆ process() [2/2]

template<typename ENUM_TYPE>

void ml::EventReceiver::process	(	ENUM_TYPE	eventName,
		const std::optional< sf::Event > &	event )

Invoke all callbacks registered for eventName.

Template overload that accepts any enum value directly, converting to a string key via EnumKey::get() internally.

Template Parameters

ENUM_TYPE Any enum type.
