用pyqt5和qt設計器打開第二個窗口

Question

我使用pyqt5和QtDesigner創建了兩個窗口的應用程序。主窗口「MainWindow.ui」上的按鈕應該從文件「age_entry.ui」打開第二個窗口，但我似乎缺少一些東西。點擊第一個窗體上的按鈕產生這個錯誤「：

異常 」未處理的類型錯誤「 QDialog的（父：QWidget的=無，國旗：聯盟[Qt.WindowFlags，Qt.WindowType] = Qt.WindowFlags（） ）：參數1有意想不到的類型 '布爾'

下面是主窗口中的代碼：

# -*- coding: utf-8 -*- 

import sys 
from PyQt5 import uic, QtWidgets 


Ui_MainWindow, QtBaseClass = uic.loadUiType("MainWindow.ui") 
LandingPageUI, LandingPageBase = uic.loadUiType("age_entry.ui") 

class MyApp(QtWidgets.QMainWindow, Ui_MainWindow): 

    def __init__(self): 
     QtWidgets.QMainWindow.__init__(self) 
     Ui_MainWindow.__init__(self) 
     self.setupUi(self) 

     def showAgeEntryForm(self): 
      self.child_win = AgeEntryForm(self) 
      self.child_win.show()    

     self.btnOpenAges.clicked.connect(showAgeEntryForm)    


class AgeEntryForm(LandingPageBase, LandingPageUI): 
    def __init__(self, parent=None): 
     LandingPageBase.__init__(self, parent) 
     self.setupUi(self)    



if __name__ == "__main__": 
    app=QtWidgets.QApplication.instance() 
    if not app: 
     app = QtWidgets.QApplication(sys.argv) 

    window = MyApp() 
    window.show() 
    sys.exit(app.exec_()) 

在此先感謝

這裏是主窗口，並以代碼的形式age_entry文件：

而且age_entry.ui

Answer 1

兩個問題你的縮進是錯誤的。其次你失去了自我。在showAgeEntryForm上。試試這個：

def __init__(self): 
    QtWidgets.QMainWindow.__init__(self) 
    Ui_MainWindow.__init__(self) 
    self.setupUi(self) 
    self.btnOpenAges.clicked.connect(self.showAgeEntryForm) 

def showAgeEntryForm(self): 
    self.child_win = AgeEntryForm(self) 
    self.child_win.show()
