如何調用UI類QT5在Python

這是必須調用UI類的類：如何調用UI類QT5在Python

class mainpanelManager(QtGui.QGuiApplication, Ui_MainWindow): 
    def __init__(self): 
     QtGui.QGuiApplication.__init__(self) 
     Ui_MainWindow.__init__(self) 
     self.setupUi(self) 


if __name__ == "__main__": 
    app = QtGui.QGuiApplication(sys.argv) 
    window = mainpanelManager() 
    window.show() 
    sys.exit(app.exec_())

當我運行class mainpanelManager我得到這個錯誤：

QtGui.QGuiApplication.__init__(self) 
TypeError: QGuiApplication(List[str]): not enough arguments

請給我一些建議如何從運行的UI類另一個班級。我在做什麼錯？我發現的樣本使用的是import PyQt4 import QtCore, QtGui, QtWidgets，但在我的情況下（使用Qt5）沒有QApplication選項，如Qt4。似乎Qt5使用QtGui.QGuiApplication。我無法理解這一點。任何幫助將受到歡迎。請詳細解釋。我在Python中仍然很新。

那裏有很多代碼。也許你可以做一個[mcve]？ –

你需要從Qt設計頂層對象匹配的子類 - 在這種情況下，似乎是一個QMainWindow：

class mainpanelManager(QtWidgets.QMainWindow, Ui_MainWindow): 
    def __init__(self): 
     super().__init__() 
     self.setupUi(self)

而且你應該使用QApplication：

if __name__ == "__main__": 
    app = QtWidgets.QApplication(sys.argv) 
    window = mainpanelManager() 
    window.show() 
    sys.exit(app.exec_())

PS：

PyQt4與PyQt5不兼容。請參閱：Differences Between PyQt4 and PyQt5。

PPS：

它也像你嘗試編輯由pyuic生成的模塊。永遠不要這樣做。我建議你重新運行pyuic，以便獲得一個乾淨的模塊。
