reading text value from QLineEdit located in a different module

well this is turning out so weird or maybe I am doing it wrong

I am trying to read the value of QLineEdit text box but i am getting it empty

basically I wrote file in pyQt4 for UI,called RenderUI.py

and now from render.py

i am trying to access QLineEdit but getting it empty even when it filled with text
Below is render.py file and from it I did importation of RenderUI as ren
i can access the selected text from the QComboBox but not QLineEdit ??:( where I have print obj.scnFilePath.text()

Code:

---

import RenderUI as ren
import sys,os
from PyQt4 import QtCore,QtGui
 
class Actions(QtGui.QWidget):
      def __init__(self):
          pass
##          super(Actions,self).__init__(self)
 
      def makebatFileTasks(self):
          obj=ren.Window()
 
          print obj.scnFilePath.text()
 
          ## building the render string for bat file
          print "render -r " + obj.renderer[str(obj.rndCB.currentText())] +"\
 -im "

what is Window()?

maybe scnFilePath isn't the same lineedit that is on the gui.
