Switching from QDialog to another QDialog window

LT-K101

I have a QMainWindow and Two QDialog windows, moving to the second QDialog window seem not working with a help of a next button. I think I might be doing something wrong here. Please I need assistance, below is my code. Thanks.

QMainWindow Code

from PyQt5 import QtCore, QtGui, QtWidgets
from NewEmployee import AddEmployee


class EmployeeWindow(QtWidgets.QMainWindow):

    def __init__(self, mainMenu):
        super(EmployeeWindow, self).__init__()
        self.mainMenu = mainMenu

        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

        self.ui.Back_Button.clicked.connect(self.Back_To_MainMenu)
        self.ui.Add_Employee_Button_2.clicked.connect(self.Add_New_Employee)


    def Back_To_MainMenu(self):
        self.hide()

        self.mainMenu.show()


    def Add_New_Employee(self):
        self.addEmployee = AddEmployee()
        first_result = self.addEmployee.exec()

First QDialog Window Code

from PyQt5 import QtCore, QtGui, QtWidgets
from OtherEmployee_info import OtherEmployee


class AddEmployee(QtWidgets.QDialog):

    def __init__(self):
        super(AddEmployee, self).__init__()
        self.ui = Ui_Dialog()
        self.ui.setupUi(self)


class SecondEmployee(QtWidgets.QDialog):

    def __init__(self):
        super(SecondEmployee, self).__init__()

        self.ui = Ui_Dialog()
        self.ui.setupUi(self)


        self.ui.New_Employee_Next_Button.clicked.connect(Open_Second_Employee_Window)


    def Open_Second_Employee_Window(self):
        self.secondEmployee = SecondEmployee()
        second_result = self.secondEmployee.exec()

Second QDialog Window Code

from PyQt5 import QtCore, QtGui, QtWidgets

class OtherEmployee(QtWidgets.QDialog):

    def __init__(self):
        super(OtherEmployee, self).__init__()
        self.ui = Ui_Dialog()
        self.ui.setupUi(self)

Hi,

You are creating event loops within event loops with your code.

If you want to implement some sort of wizard, then you should consider using QWizard, otherwise, you should rather consider the use of QStackedWidget to switch from one widget to another within your dialog.

@SGaist Thanks for your responds. I'm new to python and I'm kind of confused right now with Qwizard and QstackedWidget , could you please assist with some code so i can understand you properly please?

@LT-K101 https://doc.qt.io/qt-5/qwizard.html has already example code. What exactly is not clear?

LT-K101

@jsulm I have a main.py file and QMainWindow.py file as the second page. Now I want to create two more pages using Qwizard within the QMainWindow. I used Qt designer in designing all my pages and converted them to .py files.

@LT-K101 Still not sure what the problem is.
Here is some Python example code: https://doc.qt.io/archives/qtforpython-5.12/PySide2/QtWidgets/QWizard.html
You create a QWizard instance, add pages to it and show it.

@jsulm Thanks for your assistance, can I show you my code if you don't mind?

Main.py

from PyQt5 import QtWidgets, QtCore
from mainmenu import MainWindow

if name == "main": import sys

app = QtWidgets.QApplication(sys.argv)

mainwindow = MainWindow()
mainwindow.show()

sys.exit(app.exec_())

mainMenu.py

from PyQt5 import QtCore, QtGui, QtWidgets
from ManageEmployee import EmployeeWindow


class MainWindow(QtWidgets.QMainWindow):

    def __init__(self):
        super(MainWindow, self).__init__()

       self.ui = Ui_MainWindow()
       self.ui.setupUi(self)

       self.ui.Reg_Emp_Button.clicked.connect(self.manage_reg_Employees)
    

   def manage_reg_Employees(self):
       self.hide()
       self.employeeWindow = EmployeeWindow(self)
       self.employeeWindow.show()

ManageEmployee.py

class EmployeeWindow(QtWidgets.QMainWindow):

     def __init__(self, mainMenu):
         super(EmployeeWindow, self).__init__()
         self.mainMenu = mainMenu

         self.ui = Ui_MainWindow()
         self.ui.setupUi(self)

         self.ui.Back_Button.clicked.connect(self.Back_To_MainMenu)
         
     def Back_To_MainMenu(self):
         self.hide()

         self.mainMenu.show()

@LT-K101 said in Switching from QDialog to another QDialog window:

can I show you my code if you don't mind?

Sure. But what exactly is the problem?

LT-K101

@jsulm From the code I have posted above, what I want to do is click a PushButton in the last QMainWindow(ManageEmployee.py) and a first QDialog page will show. Again when I click on a PushButton from the first QDialog it should show a second QDialog window. I do not know what code to put in the ManageEmployee.py script
