PointerThrower

from acron.core import PointerThrower

class PointerThrower

Bases:

Bases: DataNode

Throws an event for each pointer that goes down, moves while it is down and goes up: each finger on a touch screen, say. The events carry the pointer’s identifier and its position in window pixels, followed by any parameters added with add_parameter().

This is a DataNode which is intended to be parented to the data graph below a device which is generating a sequence of pointer events, like a MouseAndKeyboard device.
