QMessageBox does not open and throws an error

PyGrrl_FL

Hi all,

I am trying to get a dialog box to open and it will not. It throws the following error: TypeError: setWindowTitle(self, str): first argument of unbound method must have type 'QMessageBox'

This is the code I am trying to run:

import sys
import pyodbc
from datetime import datetime as dt
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QPalette
from PyQt5.QtWidgets import QApplication, QDialog, QLineEdit, QFormLayout, QPushButton, QMessageBox, QLabel

class StartForm(QDialog):
    def __init__(self, parent=None):
        super(StartForm,self).__init__(parent)
        self.setGeometry(50, 50, 150, 150)
        self.setWindowTitle("TERM TEMPLATE DATABASE INSERT")

        # Create widgets
        self.myCourseCodeInput = QLineEdit(self)
        self.QCourseCodeLabel = QLabel("Enter the Course Code for new template: ")
        self.myTermCodeInput = QLineEdit(self)
        self.QTermCodeLabel = QLabel("Enter the term code (yymmdd) for the new template: ")
        self.startTermTemplateInsertBtn = QPushButton("PROCESS NEW TERM TEMPLATE")
        self.cancelBtn = QPushButton("EXIT APPLICATION")

        # Create layout and add widgets
        layout = QFormLayout()
        layout.addRow(self.QCourseCodeLabel,self.myCourseCodeInput)
        layout.addRow(self.QTermCodeLabel,self.myTermCodeInput)
        layout.addRow(self.startTermTemplateInsertBtn, self.cancelBtn)

        # Set dialog layout
        self.setLayout(layout)
        self.myCourseCodeInput.setEnabled(True)
        self.myTermCodeInput.setEnabled(True)
        self.startTermTemplateInsertBtn.setEnabled(True)

        # Connect buttons and checkbox to actions
        self.startTermTemplateInsertBtn.clicked.connect(self.termInfoVerify)

    def templateData(self, appTerm, cursor):
        cid = self.myCourseCodeInput.text().upper()
        appTerm = self.myTermCodeInput.text()
        termDate = dt.strptime(appTerm, '%y%m%d') #Put term input in python datetime format
        tDate = termDate.strftime('%y%m%d') #Convert python format term date to UMA term code format
        xTermDate = termDate.strftime('%Y-%m-%d') #Expand term date to yyyy-mm-dd format
        termTemplate = 'TEMPLATE_' + cid + '_' + tDate
        self.termInfoVerify()

    def termInfoVerify(self):
        cidText = self.myCourseCodeInput.text().upper()
        termDate = self.myTermCodeInput.text()    
        QMessageBox.Question()
        QMessageBox.setWindowTitle(self, "Template Info Verification")
        QMessageBox.setText(self, "You entered the following term template information:")
        QMessageBox.setDetailedText(self, "Course Code:" + cidText)
        QMessageBox.setDetailedText(self, "Term Date: " + termDate)
        QMessageBox.setInformativeText(self, "Click 'OK' to process the information.  Click 'Cancel' to make corrections.")
        QMessageBox.setStandardButtons(QMessageBox.Ok | QMessageBox.Cancel)


# Create the Qt Application
app = QApplication(sys.argv)
app.setStyle('Fusion')
palette = QPalette()
palette.setColor(QPalette.ButtonText, Qt.blue)
app.setPalette(palette)

# Create and show the form
form = StartForm()
form.show()

# Run the main Qt loop
sys.exit(app.exec())

Any help is greatly appreciated!

@PyGrrl_FL said in QMessageBox does not open and throws an error:

setWindowTitle

This is not a static method! question() is static.
You need to create a QMessageBox instance and then show it using exec():

msg = QMessageBox()
msg.setWindowTitle(self, "Template Info Verification")
msg.setText(self, "You entered the following term template information:")
msg.setDetailedText(self, "Course Code:" + cidText)
msg.setDetailedText(self, "Term Date: " + termDate)
msg.setInformativeText(self, "Click 'OK' to process the information.  Click 'Cancel' to make corrections.")
msg.setStandardButtons(QMessageBox.Ok | QMessageBox.Cancel)
msg.exec()

If you want to use static question() method then please check its documentation and pass the parameters in the correct way:

QMessageBox.question(self, "Template Info Verification", ...)

Thanks, jsulm! I see now where my mistake is. I was mixing things around. I was able to get it working with your guidance.
