PYQT4: Kritische Message Box

Question

Okay, nicht sicher, was ich hier vermisse. Ich habe eine GUI-App für Arbeit erstellt, die eine Schließen-Schaltfläche enthält. Ich bin in der Lage, die closeEvent Funktion auszuführen, wenn der Benutzer die Schaltfläche zum Schließen des benutzerdefinierten Fensters verwendet. Wenn sie jedoch auf die Schließen-Schaltfläche in der GUI klicken, kann ich nicht den gleichen Effekt erzielen. Unten ist mein Code, der Fehler und ein Bild meiner GUI, das mein Problem zeigt. Vielen Dank im Voraus für die Hilfe.

Answer 1

Der Code, den Sie haben einen Fehler, da QMessageBox.critical Bedürfnisse ein QObject Objekt zu übergeben und Ui_MainWindow nicht.

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() 

Außerdem möchten Sie, dass die Schaltfläche Standard und ein Schließen-Schaltfläche das gleiche Verhalten schließen drücken, müssen Sie das Signal anschließen, der die neue Schaltfläche mit der Schließfunktion abgibt, da die Schließfunktion closeEvent ruft .

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() 

Verbindung löschen: self.btnExit.clicked.connect(self.ExitClicked) und Funktion def ExitClicked(self): ...
