AutoResize Existing Main Window pyqt5

i already designed a QMainWindow with QT Designer contain centralWidget which contain
pushbutton
labels
textEdit
after coding all the project I realized that the mainwindow doesn't fit all PC screens
so I need to auto resize all objects to fit when I try layout vertically or horizontally
all object's positions change

How do I make Average Mark Calculator in PyQT?

First You have to pass arguments to results function
and marks = [] will reset the marks list every time a button is pressed..
so better make marks global variable by self.marks = [] and append integers to it..
so to append numbers to it use self.marks.append(int(number))
and remove the numbers argument from results as it is not necessary
so results function will look like this..
def results(self, marks):
res = sum(marks) / len(marks)
print(res) #or return as your wish
write_number function should look like this
def write_number(self, number):
self.marks.append(int(number))
self.Marks.setText(self.Marks.text() + number)
and declare the self.marks variable after self.add_functions() statement
self.add_functions()
self.marks = []
and change Apply button connect Function
self.Apply.clicked.connect(lambda: self.results(self.marks))
so add_function should look like this..
def add_functions(self):
self.one.clicked.connect(lambda: self.write_number(self.one.text()))
self.two.clicked.connect(lambda: self.write_number(self.two.text()))
self.three.clicked.connect(lambda: self.write_number(self.three.text()))
self.four.clicked.connect(lambda: self.write_number(self.four.text()))
self.five.clicked.connect(lambda: self.write_number(self.five.text()))
self.Apply.clicked.connect(lambda: self.results(self.marks))

How to pass parameters bw two windows in pyqt5?

I am working on a password manager gui app. Using Qtdesigner I created a main window where I asked for username and password from user. and a dialog window where display the user their username and passwords for different apps and websites. I also called that dialog window from my main window so that when user press login button then if their login credential is correct , the dialog window will appear.
Now what I want is that when dialog window appears,after clicking push button it should show all data of the user which is stored in a table with that username(like if username is alex then a table with name alex is there in db with username and passwords of different apps/websites).
Hope my question is understandable enough to be answered. I can further clarify if anyone interested to answer.

I use the QStackedWidget to switch between pages.
app = QApplication(sys.argv)
stackedwidget = QtWidgets.QStackedWidget()
page1 = PageOneClass()
page2 = PageTwoClass()
stackedwidget.addWidget(page1)
stackedwidget.addWidget(page2)
stackedwidget.show()
app.exec_()
This will let you switch between pages without running another file. Now to get values from one page to another, use inheritance.
class MainWindow(QMainWindow):
def __init__(self):
super(MainWindow, self).__init__()
self.user = self.username.text()
self password = self.password.text() #Now the user, password can be accessed using the class name. dont forget to add self.
class DialogWindow(MainWindow):
def __init__(self, MainWindow):
super(DialogWindow, self).__init__()
usernamefrompage1 = MainWindow.user
passwordfrompage1 = MainWindow.password
app = QApplication(sys.argv)
stackedwidget = QtWidgets.QStackedWidget()
mainwindow_instance = MainWindow()
dialogwindow_instance = DialogWindow(mainwindow_instance)
#we are passing the mainwindow instance to the dialog window instance, this will let us use all the methods and attributes of the mainwindow.
stackedwidget.addWidget(mainwindow_instance)
stackedwidget.addWidget(dialogwindow_instance)
stackedwidget.setCurrentWidget(mainwindow_instance)
stackedwidget.show()

PyQt5 identical push buttons, one works one doesn't

I want Checkbutton on click event to work, please help

For Ui_Premix, used self.Checkbutton.clicked.connect(Ui_PREMIX.on_click) instead of
self.on_click even though on_click event was inside class, it works now
