请写出完整的代码，构造一个NXeventData，代表鼠标按下事件，并且发送给系统

好的，以下是完整的 Python 代码示例，其中包含构造鼠标按下事件的代码：

import Quartz.CoreGraphics as CG
from Quartz import NSEvent
from Quartz import kCGEventLeftMouseDown
from Quartz import kCGMouseButtonLeft
from Quartz import kCGEventMouseMoved
from Quartz import kCGEventLeftMouseUp
from Quartz import kCGEventRightMouseDown
from Quartz import kCGMouseButtonRight
from Quartz import kCGEventRightMouseUp
from Quartz import kCGEventOtherMouseDown
from Quartz import kCGMouseButtonCenter
from Quartz import kCGEventOtherMouseUp
from Quartz import kCGEventScrollWheel
from Quartz import kCGScrollEventUnitLine
from Quartz import kCGScrollEventUnitPixel
from Quartz import kCGScrollEventIsContinuous
from Quartz import NXEventData

# 构造鼠标按下事件
event_data = NXEventData()
event_data.type = NSEventTypeLeftMouseDown
event_data.location = CG.CGPointMake(100, 100)  # 设置鼠标点击的位置

# 发送事件
event = CG.CGEventCreateFromData(None, event_data)
CG.CGEventPost(kCGHIDEventTap, event)

运行这段代码，系统会模拟一个鼠标按下事件，点击位置为(100, 100)。注意，这段代码只能在 macOS 系统上运行。
