on_held()

void MayaFlux::Portal::Forma::Context::on_held	(	uint32_t	id,
		IO::Keys	key,
		KeyFn	fn
	)

Called repeatedly while a key is held and the element has focus.

Fires on initial press and continues on each repeat tick until the key is released. Useful for continuous adjustments (arrow key nudging, value increments) without requiring the user to repeatedly press.

Parameters

id	Element id to bind to.
key	The key to listen for.
fn	Callback receiving element id, fired on press and each repeat.
