AttributeError: объект dataAcquisition не имеет атрибута 'gpioButton'

Question

Я пытаюсь подключить кнопку в своем главном окне, чтобы открыть новый виджет, когда я нажимаю на него. Но каждый раз, когда я запускаю программу, я получаю эту ошибку:

AttributeError: 'dataAcquisition' object has no attribute 'gpioButton'

Буду благодарен, если кто-то может помочь.

Вот мой код:

from PyQt4 import QtCore, QtGui 
from mainwindow import Ui_MainWindow 
from gpiodialog import Ui_GPIODialog 
import sys 

class gpioDialog(QtGui.QDialog, Ui_GPIODialog): 
    def __init__(self, parent=None): 
     QtGui.QDialog.__init__(self, parent) 
     flags = QtCore.Qt.Drawer | QtCore.Qt.WindowStaysOnTopHint 
     self.setWidowFlags(flags) 
     self.ui = Ui_GPIODialog 
     self.ui.setupUi(self) 

     self.gpioOKButton.clicked.connect(self.acceptOKButtonClicked) 
    def acceptOKButtonClicked(self): 
     self.close()   


class dataAcquisition(QtGui.QMainWindow, Ui_MainWindow): 
    def __init__(self, parent=None): 
     QtGui.QMainWindow.__init__(self, parent) 
     self.ui = Ui_MainWindow() 
     self.ui.setupUi(self) 

     self.gpioButton.clicked.connect(self.gpioButton_clicked) 
     self.popGPIO = gpioDialog() 

    def gpioButton_clicked(self): 
     self.popGPIO.show() 

if __name__ == '__main__': 
    app = QtGui.QApplication(sys.argv) 
    MainWindow = dataAcquisition() 
    MainWindow.show() 
    sys.exit(app.exec_())

Вы создали отдельное пространство имен для пользовательского интерфейса, так что вы необходимо будет получить доступ к этой кнопке:

self.ui.gpioButton.clicked.connect(self.gpioButton_clicked) 

Однако, если вы предпочитаете, чтобы все виджеты как атрибуты окна, выполните следующие действия:

class gpioDialog(QtGui.QDialog, Ui_GPIODialog): 
    def __init__(self, parent=None): 
     super(gpioDialog, self).__init__(parent) 
     flags = QtCore.Qt.Drawer | QtCore.Qt.WindowStaysOnTopHint 
     self.setWindowFlags(flags) 
     self.setupUi(self) 
     self.gpioOKButton.clicked.connect(self.acceptOKButtonClicked) 


class dataAcquisition(QtGui.QMainWindow, Ui_MainWindow): 
    def __init__(self, parent=None): 
     super(dataAcquisition, self).__init__(parent) 
     self.setupUi(self) 
     self.gpioButton.clicked.connect(self.gpioButton_clicked) 
     self.popGPIO = gpioDialog()
