Detailed Description

Represents a UI event with type, target, and optional data.

The Event class encapsulates user interactions and system events that can be propagated through the component hierarchy. Events have a type (e.g., "click"), a target component, and optional type-erased data payload.

T Event::getData ( void  ) const

inline

Get the event data with type casting.

Template Parameters

T	The type to cast the data to

Returns

getTarget()

std::shared_ptr< Component > Event::getTarget ( void  ) const

inline

Get the target component.

Returns

Shared pointer to the target component

getType()

const std::string & Event::getType ( void  ) const

inline

Get the event type.

Returns

The event type string

hasData()

bool Event::hasData ( void  ) const

inline

Check if the event has data.

Returns

true if data is present, false otherwise
