text_input()

MAYAFLUX_API Vruta::Event MayaFlux::Kriya::text_input	(	std::shared_ptr< Core::Window >	window,
		std::function< void(uint32_t)>	callback
	)

Creates an Event coroutine that triggers on resolved text input.

Delivers composed Unicode codepoints (shift, layout, dead-key/compose, and IME already resolved by the backend), distinct from key_pressed's raw keycodes. See Core::WindowEventType::TEXT_INPUT.

Parameters

window	Window to listen to.
callback	Called with the resolved Unicode codepoint.

Returns

Event coroutine that can be added to EventManager.
