PYQT4: Critical Message Box
Okay, not sure what I am missing here. I have created a GUI app for work, which contains a close button. I am able to get the closeEvent function to execute, if the user uses the custom window close button. However, when they click the close button on the GUI, I can't produce the same effect. Below is my code, the error and a picture of my GUI demonstrating my issue. Thanks in advance for the help.

Solution
The code you have generates an error because QMessageBox.critical needs to pass a QObject object and Ui_MainWindow is not.
class Ui_MainWindow(object):
....
def ExitClicked(self):
ret = QMessageBox.critical(self, "Critical",
'Are you sure you want to exit?', QMessageBox.Ok, QMessageBox.Cancel)
ret = msgBox.exec_()
if ret == msgBox.Yes:
QtCore.QCoreApplication.instance().quit()
In addition you want that pressing the button to close default and your new close button have the same behavior, you have to connect the signal that emits the new button with the close function,since the close function calls closeEvent.
class Ui_MainWindow(object):
....
class ControlMainWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
super(ControlMainWindow, self).__init__(parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.ui.btnExit.clicked.connect(self.close)
....
def closeEvent(self, event):
result = QtGui.QMessageBox.critical(self,
"Confirm Exit...",
"Are you sure you want to exit?",
QtGui.QMessageBox.Yes | QtGui.QMessageBox.No)
event.ignore()
if result == QtGui.QMessageBox.Yes:
event.accept()
Delete connection: self.btnExit.clicked.connect(self.ExitClicked) and function def ExitClicked(self): ...
