PyQT4 how to using def from others model

Question

This code works:

import sys
from PyQt4 import QtCore, QtGui, QtWebKit
from forma import Ui_MainWindow

class MyForm(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        QtCore.QObject.connect(self.ui.pushButton,QtCore.SIGNAL("clicked()"), self.strona)

    def strona(self):
        self.ui.webView.setUrl(QtCore.QUrl("http://plemiona.pl"))

but this

funkcje.py

from PyQt4 import QtCore, QtGui, QtWebKit
from forma import Ui_MainWindow

def strona():
        self.ui.webView.setUrl(QtCore.QUrl("http://xxxx.pl"))



import sys, time, funkcje
from PyQt4 import QtCore, QtGui, QtWebKit
from forma import Ui_MainWindow

class MyForm(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        QtCore.QObject.connect(self.ui.pushButton,QtCore.SIGNAL("clicked()"), funkcje.strona)

doesn't work...

Traceback (most recent call last):
  File "C:\Python33\liczbapierwsza\TribalWarsBot\funkcje.py", line 5, in przejdz_na_strone_plemion
    QtGui.QWidget.__init__(self, parent)
NameError: global name 'self' is not defined

how to import function from funkcje.py and use in ex run.py

Answer 1

strona needs to have access to the class instance, self. I'm not sure how you would go about passing the self parameter using Qt, but you can always write a wrapper function as part of your class that calls strona and passes the self parameter. Or import types and add types.MethodType(funkcje.strona, self, MyForm) to the class constructor( __init__ ). That adds funkcje.strona to the class. Note that the latter is untested by me.

EDIT: Here is what to do:

class MyForm(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        types.MethodType(strona, self, MyForm) 
        QtCore.QObject.connect(self.ui.pushButton,QtCore.SIGNAL("clicked()"), strona)

Note: This is untested.
