Pyqt: AttributeError: 'Object' has not attribute 'someFunction'

s03r3n

Hey there.

I am trying to run this example:
@import sys
from PyQt4 import QtGui, QtCore

class Window(QtGui.QWidget):

def __init__(self):
    super(Window, self).__init__()       
    self.initUI()

def initUI(self):
    self.setWindowTitle('Who is online?')
    self.setGeometry(50, 50, 730, 326)

    self.labelF = QtGui.QLabel(self)
    self.labelF.setGeometry(QtCore.QRect(395, 50, 111, 31))
    self.labelF.setFrameShape(QtGui.QFrame.StyledPanel)
    self.labelF.setAlignment(QtCore.Qt.AlignCenter)
    self.labelF.setText('')

    self.pushButton = QtGui.QPushButton("Quit", self)
    self.pushButton.setGeometry(QtCore.QRect(620, 290, 101, 27))
    self.pushButton.clicked.connect(QtCore.QCoreApplication.instance().quit)

    self.buttonA = QtGui.QPushButton("A", self)
    self.buttonA.setGeometry(QtCore.QRect(110, 290, 101, 27))
    self.buttonA.clicked.connect(self.setA)

    self.show()

def setA(self):
self.labelF.setText('InstructorA')

def setD(self):
self.labelF.setText('InstructorB')

def main():
app = QtGui.QApplication(sys.argv)
ex = Window()
sys.exit(app.exec_())

if name == 'main':
main()
@

The button 'buttonA' is causing an error with the function 'setA'. The error message says:
Attribute Error "'Window' has no attribute 'setA'"

I compared my code to other examples that use a button and can't figure out how my code differs from those examples... Any help would be appreciated. Thanks in advance!

Hi and welcome to devnet,

Might be a silly question but did you indent your source correctly ? The code you posted shows that setA is not part of Window since it's at the same level as e.g. main
