Member Function Documentation

filter()

bool ml::DraggableDispatcher::filter ( const std::optional< sf::Event > & event, Core * component )

override

fire()

void ml::DraggableDispatcher::fire ( const std::optional< sf::Event > & event )

overridevirtual

Deliver this event to all matching registered components.

Called by the framework after occurred() returns true. Typically iterates the component list and calls process() on each component that passes filter().

Parameters

event

The SFML event that triggered this dispatch, or std::nullopt for synthetic/frame-driven events.

Implements ml::EventDispatcher.

occurred()

bool ml::DraggableDispatcher::occurred ( const std::optional< sf::Event > & event )

overridevirtual

Return true when the incoming SFML event should trigger this dispatcher.

Called once per event by the framework before any components are visited. Return false to skip the entire dispatch pass for this event.

Parameters

event

The SFML event to evaluate, or std::nullopt.

Returns

true if this dispatcher should fire for event.

Implements ml::EventDispatcher.
