Python PyQt5 QMessageBox not opening
问题 I am trying to open a Message Box when I press the infoButton. It runs the infoDialogue method because it prints "I'm here" but it doesn't open the infoBox. What I'm missing? I'm using python 3.5 with PyQt5 Thanks! Here's the code: import sys from PyQt5.QtWidgets import (QApplication, QWidget, QToolTip, QPushButton, QMessageBox) from PyQt5.QtCore import QCoreApplication from PyQt5.QtGui import QIcon, QFont class mainWindow(QWidget): def __init__(self, screenWidth, screenHeight, windowWidth
