经过短短几个小时的谷歌搜索和实验,终于得到了这个工作:)看起来罗德里戈试图说你必须在构建它之后调用CGEventSetIntegerValueField
鼠标kCGMouseEventDeltaX
事件kCGMouseEventDeltaY
。
我的代码,使用 PyObjC:
from Quartz.CoreGraphics import (
CGEventCreate,
CGEventCreateMouseEvent,
CGEventGetLocation,
CGEventPost,
CGEventSetIntegerValueField,
kCGEventMouseMoved,
kCGHIDEventTap,
kCGMouseEventDeltaX,
kCGMouseEventDeltaY,
)
def mouse_delta(delta_x, delta_y):
"""
Send a MouseMoved event with the given deltaX and deltaY attributes,
but without changing the cursor location.
"""
# Might be a better way to get the current mouse location
x, y = CGEventGetLocation(CGEventCreate(None))
# The `mouseButton` parameter to CGEventCreateMouseEvent is ignored
# unless `mouseType` is kCGEventOtherMouse{Down,Dragged,Up},
# so let's just pass the value 0
event = CGEventCreateMouseEvent(None, kCGEventMouseMoved, (x, y), 0)
CGEventSetIntegerValueField(event, kCGMouseEventDeltaX, delta_x)
CGEventSetIntegerValueField(event, kCGMouseEventDeltaY, delta_y)
return CGEventPost(kCGHIDEventTap, event)
