import shiboken2
import maya.OpenMayaUI as mui

def getMayaWindow():
    main_window_ptr = mui.MQtUtil.mainWindow()
    return shiboken2.wrapInstance(long(main_window_ptr), QtWidgets.Qwidget)

from PySide2 import QtWidgets
import pymel.core as pm
from maya import OpenMayaUI
import shiboken2   
def maya_mainwindow():
    maya_main_window_name = pm.language.melGlobals['gMainWindow']
    maya_main_window = OpenMayaUI.MQtUtil.findControl(maya_main_window_name)
    widget = shiboken2.wrapInstance(long(maya_main_window), QtWidgets.QWidget)
    return widget

widget有个StayOnTopHint,设置一下就好
