PyQt5 messagebox

Python hosting: Host, run, and code Python in the cloud!

In this article you will learn how to create a PyQt5 messagebox:

pyqt5-messagebox

To show a messagebox we need to import QMessageBox.


from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMessageBox

We use the method QMessageBox.question() to display the messagebox.

PyQt5 messagebox code
Copy the code below to display a messagebox.


import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMessageBox
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot

class App(QWidget):

def __init__(self):
super().__init__()
self.title = 'PyQt5 messagebox - pythonspot.com'
self.left = 10
self.top = 10
self.width = 320
self.height = 200
self.initUI()

def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)

buttonReply = QMessageBox.question(self, 'PyQt5 message', "Do you like PyQt5?", QMessageBox.Yes | QMessageBox.No, QMessageBox.No)
if buttonReply == QMessageBox.Yes:
print('Yes clicked.')
else:
print('No clicked.')

self.show()

if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())

More buttons for a messagebox
Take into account we use QMessageBox.Yes and QMessageBox.No. We can easily add other options:


buttonReply = QMessageBox.question(self, 'PyQt5 message', "Do you want to save?", QMessageBox.Yes | QMessageBox.No | QMessageBox.Cancel, QMessageBox.Cancel)
print(int(buttonReply))
if buttonReply == QMessageBox.Yes:
print('Yes clicked.')
if buttonReply == QMessageBox.No:
print('No clicked.')
if buttonReply == QMessageBox.Cancel:
print('Cancel')

The available buttons are:

Overview
QMessageBox.Cancel QMessageBox.Ok QMessageBox.Help
QMessageBox.Open QMessageBox.Save QMessageBox.SaveAll
QMessageBox.Discard QMessageBox.Close QMessageBox.Apply
QMessageBox.Reset QMessageBox.Yes QMessageBox.YesToAll
QMessageBox.No QMessageBox.NoToAll QMessageBox.NoButton
QMessageBox.RestoreDefaults QMessageBox.Abort QMessageBox.Retry
QMessageBox.Ignore
