Adding PyQt Gui Elements from Another File

I am learning PyQt and coming from webdesign, so excuse this question, which should have a very obvious answer. Therefore, I am creating a PyQt application, and I would like to extend the methods to multiple files to fit different parts of the GUI. How can I access the text field located in the A..py file from the file.

#fileA.py
import sys
from PyQt4 import QtGui, QtCore
from gui1 import Ui_MainWindow
import fileB

class MyApp(QtGui.QMainWindow, Ui_MainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self)
        Ui_MainWindow.__init__(self)
        self.setupUi(self)


if __name__ == "__main__":
        app = QtGui.QApplication(sys.argv)
        window = MyApp()
        window.show()

        #This works all fine
        def pressed():
            window.plainTextEdit.appendPlainText("Hello")


        window.pushButton.pressed.connect(pressed)


        window.button2.pressed.connect(fileB.func3)
        sys.exit(app.exec_())

Now in this file I would like to use the text box from file.pp

#fileB.py
import fileA

    #How do I access window.plainTextEdit from fileA.py
def func3():
    print "hello"
    fileA.window.plainTextEdit.appendPlainText("Hello")

What am I doing wrong? What would be the best way to extend functionality to multiple files if not for this?

Thanks for taking the time to read this.

You can use Python class inheritance, for example:

fileA.py

import sys
from PyQt4 import QtGui, QtCore
from gui1 import Ui_MainWindow
import fileB

class MyApp(fileB.MyApp, QtGui.QMainWindow):
  def __init__(self):
     self.MyMethod()
     # Should print 'foo'

fileB.py

import sys
from PyQt4 import QtGui, QtCore
from gui1 import Ui_MainWindow

class MyApp(QtGui.QMainWindow):
  def MyMethod(self):
    print 'foo'

, -, if __name__ == "__main__" , fileA.py, fileA.window . , : , __name__ "__main__", . fileA.py, QApplication window, window.plainTextEdit. , MyApp fileB. , , MyApp, , , fileB.py . , .

, ;

window = MyApp()
window.plainTextEdit.appendPlainText("Hello")

fileB, .
