How do I get variables from my main module in Python?

I am a Structural Engineer by trade and I am trying to automate the creation of 3D models using scripts.
So far I have created three modules; the GUI module using PyQt4, a main module that controls the signals from the GUI, and an export module which "should" pull the variables from main module and generate a script that can be read by my analysis program.
So far the I can't pull the variables from main module when clicking the export menu in the GUI because variable names are not defined.
If I import the main module into the export module to get the variables, I get errors with the Ui_MainWindow.
I have tried to simplify what I am doing below.
main.py module
import sys
from PyQt4 import QtGui, QtCore
from gui import Ui_MainWindow
from export import newFile
class Main(QtGui.QMainWindow):
def __init__(self):
super(Main, self).__init__()
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.setName()
self.ui.actionExport.triggered.connect(self.exportName)
def exportName(self):
self.exportStaad = newFile().createNewFile()
def setName(self):
self.ui.tbo_Name.textChanged.connect(self.name_Changed)
def name_Changed(self):
someName = self.ui.tbo_Name.text()
print('Name = ' + someName)
app = QtGui.QApplication(sys.argv)
form = Main()
form.show()
app.exec_()

class newFile():
def createNewFile(dest):

'''
name = QtGui.QFileDialog.getSaveFileName ()
f = open(name, 'w')
f.write('Hello' + someName)
f.close

The method called createNewFile(dest) inside the class newFile uses undefined var someName at f.write('Hello' + someName).
This causes the error as it is not defined in the class. Define a variable before you use it.

Pyqt4 QFileDialog Constructor: what to use as parent parameter?

I'm using pyqt4 and python 2.7.11. I have a problem with the file/directory dialogs: I don't know what to use as the parent parameter.
If I use "self" or "None", PyCharm tells me that it's expecting "QFileDialog", and it got "AppTest" and "None" instead, respectively.
If I use "parent=self" or "parent=None", PyCharm tells me that the "self" parameter is unfilled.
Please see the example code below; I'm using Qt Designer to create the ui, let me know if you need that code as well.
import sys
from PyQt4 import QtGui
import ui_test as main_frame
class AppTest(QtGui.QMainWindow, main_frame.Ui_MainAppWindow):
def __init__(self, parent=None):
super(AppTest, self).__init__(parent)
self.setupUi(self)
self.pushButton1.clicked.connect(self.dialog1)
self.show()
def dialog1(self):
file1 = str(QtGui.QFileDialog.getOpenFileName(
parent=self,
caption="Locate file 1",
directory="",
filter="Graphics files (*.jpg *.jpeg)"))
print file1
def main():
app = QtGui.QApplication(sys.argv)
gui = AppTest()
sys.exit(app.exec_())
if __name__ == "__main__":
main()

The Code does not work successfully when the function is called

I want to call method (close_ok()) in (main.py ) from method :close_call() in (module_b.py), but the Code does not work successfully when the function is called.
can anyone help me with this problem?
Here's the code for that :
###main.py
# -*- coding: utf-8 -*-
from PyQt4 import QtCore, QtGui
import sys
from GUI import Ui_MainWindow
class MainWindow(QtGui.QMainWindow,Ui_MainWindow):
def __init__(self, parent=None):

self.ui = Ui_MainWindow()
self.ui.setupUi(self)
from module_c import class_c
global b
b=class_c()
QtCore.QObject.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), b.close_call )
def close_ok(self):
##But it can not be done successfully.
self.close()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
global myapp
myapp = MainWindow()
myapp.show()
sys.exit(app.exec_())
### module_b.py

def __init__(self, parent=None):
self.parent=parent
### I want call method (close_ok()) in (menu class) from here
def close_call (self):

t.close_ok()

self.pushButton.setGeometry(QtCore.QRect(340, 110, 75, 23))
self.pushButton.setObjectName(_fromUtf8("pushButton"))
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtGui.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))

def retranslateUi(self, MainWindow):
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None))
self.pushButton.setText(_translate("MainWindow", "PushButton", None))

you use diffrent instances of the class MainWindow() so it wont close the original window, change it like this:
class MainWindow(QtGui.QMainWindow,Ui_MainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
from module_c import class_c
global b
b=class_c(self) #NOTICE THE CHANGE HERE
QtCore.QObject.connect(self.ui.pushButton, QtCore.SIGNAL("clicked()"), b.close_call )
def close_ok(self):
self.close()
and change module b to do:
class class_c (object):
def __init__(self, parent=None):
self.parent=parent
def close_call (self):
from main import MainWindow
self.parent.close_ok()# NOTICE THIS CHANGE, parent is now the original MainWindow
this way you pass your original MainWindow instancce to class_c and use it, instead of creating a new instance

“Not responding” in Python.

Actually, You main GUI is not frozen at all but only for the time log gets executed and returns control to the main GUI, as you are not implementing any sort of threading mechanism in your application.
So as a solution, you need to thread log method to not block your main GUI, using threading module, the following is a generic way, you need to read more about threading:
1 - import threading in your qu.py file
2 - Define this method in qu.py as well:
def launch_Selenium_Thread(self):
t = threading.Thread(target=self.log)
t.start()
3 - Change the connect method of pushButton to:
QtCore.QObject.connect(self.pushButton,QtCore.SIGNAL(_fromUtf8("clicked()")), self.launch_Selenium_Thread)
4 -Add in qf.py log3 method, txt parameter:
def log3(self, txt):
text =unicode(txt)
print text
5 - Finally fix in qu.py log2 method:
def log2(self):
from qf import functon
n=functon()
txt = self.lineEdit.text()
n.log3(txt)

Firstly, don't edit file generated by pyuic. Make another .py file and import it. That way, instead of trying to show() the generated UI file directly, you can make a QMainWindow based class that you can run show() on and it will build the generated ui file for you. Like this:
import sys
from PyQt4 import QtCore, QtGui
from Ui_Form import Ui_Form
class Main(QtGui.QMainWindow):
def __init__(self):
super(Main, self).__init__()
# build ui
self.ui = Ui_Form()
self.ui.setupUi(self)
# connect signals
self.ui.some_button.connect(self.on_button)
def on_button(self):
print 'Button clicked!'
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
main = Main()
main.show()
sys.exit(app.exec_())
