◆ RegisterKeyActionCallback()

void open3d::visualization::VisualizerWithKeyCallback::RegisterKeyActionCallback	(	int	key,
		std::function< bool(Visualizer *, int, int)>	callback
	)

Register callback function with access to GLFW key actions.

Parameters

key	GLFW key value, see GLFW key values.
callback	The callback function. The callback function takes `Visualizer *`, `action` and `mods` as input and returns a boolean indicating UpdateGeometry() needs to be run. The `action` can be one of GLFW_RELEASE (0), GLFW_PRESS (1) or GLFW_REPEAT (2), see GLFW input interface. The `mods` specifies the modifier key, see GLFW modifier key.
