Support starting Pandora from maya.standalone

[shiqinfeng1]

I want to start Pandora from python scripts using mayapy.exe, like this:

import maya.standalone 
import maya.cmds as cmds
maya.standalone.initialize('Python')
...
cmds.loadPlugin( allPlugins=True )
Pandora.openSubmitter()
...

But error occurs in function Pandora_Maya_Functions.startup():

AttributeError: 'PySide2.QtGui.QGuiApplication' object has no attribute 'topLevelWidgets'

How to make Qt works?

I just added support for mayapy in v1.0.3.8.
You can execute this in mayapy now to open the submitter:

import sys
from PySide2.QtCore import *
from PySide2.QtWidgets import *
QApplication(sys.argv)

import maya.standalone 
import maya.cmds as cmds
maya.standalone.initialize('Python')
Pandora.openSubmitter()
qApp.exec_()
