Today we have published on PyPi our module that allows you to easily connect your odoo instance with the qt[PySide2] framework

It's very easy to use just:

pip install OdooQtUi

import sys
from PySide2 import QtWidgets
from PySide import QtGui
from OdooQtUi.connector import MainConnector

app = QtWidgets.QApplication(sys.argv)
connectorObj = MainConnector()
connectorObj.loginWithDial()    # Perform show of the login form


app.exec_()

to get a login form ..
