Python 2.7.1 / PyQt 4.8.3 / Qt 4.7.2

I have a mainwindow and a dialog designed in Qt Designer and converted to python code via pyuic4:

Mainwindow – Ui_editor.py (class is Ui_mw_editor)

Dialog1 – Ui_connect.py (class is Ui_dia_connect)

I have a menubar with actions defined in the Qt Designer (code from Ui_editor.py):

        self.actionConnect = QtGui.QAction(mw_Editor)

        icon2 = QtGui.QIcon()

        icon2.addPixmap(QtGui.QPixmap(_fromUtf8("icons/default/ToolbarConnect.png")), QtGui.QIcon.Normal, QtGui.QIcon.Off)

        self.actionConnect.setIcon(icon2)

        self.actionConnect.setObjectName(_fromUtf8("actionConnect"))

So, from my app.py file, I have this code:

import os, sys

from PyQt4 import QtCore

from PyQt4.QtGui import QMainWindow, QDialog, QApplication

from ui.Ui_Editor import Ui_mw_Editor

from ui.Ui_connect import Ui_dia_connect

class Main(QMainWindow, Ui_mw_Editor):

  def __init__(self):

        QMainWindow.__init__(self)



        self.setupUi(self)

        self.actionConnect.connect(self.connectDialog)

    def connectDialog(self):

                self.connectdlg = ConnectDlg()

                self.connectdlg.show()

class ConnectDlg(QDialog, Ui_dia_connect):

                def __init__(self):

                                QDialog.__init__(self)

                                self.setupUi(self)

                                self.actionConnect.connect(self.close)

def main():



    app = QApplication(sys.argv)

    window=Main()

    window.show()

    sys.exit(app.exec_())



if __name__ == "__main__":

    main()

###

If I remove the self.actionConnect.connect(self.connectDialog) and the supporting def and class, the mainwindow launches OK. If I include it, I get these errors:

D:\dev\f5editor>python mw2.py

Traceback (most recent call last):

File "mw2.py", line 42, in <module>

    main()

File "mw2.py", line 35, in main

    window=Main()

File "mw2.py", line 18, in __init__

    self.actionConnect.connect(self.connectDialog)

TypeError: arguments did not match any overloaded call:

QObject.connect(QObject, SIGNAL(), QObject, SLOT(), Qt.ConnectionType=Qt.AutoConnection): argument 1 has unexpected type 'instancemethod'

QObject.connect(QObject, SIGNAL(), callable, Qt.ConnectionType=Qt.AutoConnection): argument 1 has unexpected type 'instancemethod'

QObject.connect(QObject, SIGNAL(), SLOT(), Qt.ConnectionType=Qt.AutoConnection): argument 1 has unexpected type 'instancemethod'

Any help would be appreciated.

Try like that:

self.actionConnect.triggered.connect(self.connectDialog)
