QT: QDesktopWidget已弃用。我应该用什么来代替呢？

from PyQt5.QtWidgets import QApplication
from PyQt5.QtGui import QScreen

app = QApplication([])

# 获取屏幕对象
screen = QScreen()

# 获取屏幕的大小
screen_size = screen.size()
print("屏幕大小：", screen_size)

# 获取屏幕的分辨率
screen_geometry = screen.geometry()
print("屏幕分辨率：", screen_geometry.width(), "x", screen_geometry.height())

# 获取屏幕的像素密度
screen_dpi = screen.physicalDotsPerInch()
print("屏幕像素密度：", screen_dpi)
