◆ handleEvent()

bool Aether::Screen::handleEvent ( InputEvent * event )

virtual

Attempts to handle the event if it is a button press/release.

Parameters

event event to handle

Returns: Whether the event was handled by the screen.

Reimplemented from Aether::Container.

◆ onButtonPress()

void Aether::Screen::onButtonPress	(	Button	btn,
		std::function< void()>	func
	)

Assigns a function to invoke when a button is pressed.
