Question

我正在使用pyqt5和QtDesigner创建一个带有两个窗口的应用程序。主窗口“MainWindow.ui”上的一个按钮应该从文件“age_entry.ui”打开第二个窗口，但我似乎遗漏了一些东西。单击第一个表单上的按钮会产生此错误“：

异常“未处理的TypeError” QDialog（parent：QWidget = None，flags：Union [Qt.WindowFlags，Qt.WindowType] = Qt.WindowFlags（））：参数1有意外类型'bool'

以下是主窗口的代码：

# -*- 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_())

提前致谢！

以下是代码格式的MainWindow和age_entry文件：

        self.label_13 = QtWidgets.QLabel(Dialog)

        self.label_13.setText(_translate("Dialog", "Age Entry Form"))

Answer 1

你的缩进错误有两个问题。其次是你失踪的自我。在showAgeEntryForm上。试试这个：

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()

使用pyqt5和qt designer
