wire_drag()

Context & MayaFlux::Portal::Forma::Context::wire_drag	(	uint32_t	id,
		std::function< void(glm::vec2)>	sink,
		IO::MouseButtons	btn = IO::MouseButtons::Left
	)

Register a drag handler receiving only the cursor position.

Thin composition over on_drag for callers that already know the element id and have no use for it in the callback. The sink performs whatever mapping and write the gesture implies.

Parameters

id	Element id.
sink	Called with the current NDC cursor position on each drag event.
btn	Mouse button that must be held.

Returns

*this for chaining.
