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()
app.exec_()

How to close a QDialog

Closed 1 year ago.
I've created a program that allows you to login and sign up. When you have the right credentials it opens a window but it doesn't close. The same thing happens when you press the button to sign up. I've tried to use the close method but it doesn't work i always get:
AttributeError: type object 'Ui_Dialog' has no attribute 'close'

I've googled almost everywhere but the answers i seem to find are mostly for PyQt4.
I manage to find one answer about hiding the title bar and the code looks like this
self.setWindowFlag(Qt.FramelessWindowHint)
But that does not get the result I want. what i get is just the title bar gone but still there's a grey rectangular background to my program.

That white border is the internal margin of the layout so just use setContentsMargins, also for the round border you must use a mask, and obviously the Qt::FramelessWindowHint flag:
from PyQt5.QtCore import QRect, Qt
from PyQt5.QtGui import QRegion
from PyQt5.QtWidgets import QApplication, QMainWindow
from design import Ui_MainWindow
class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super().__init__(parent)
self.setupUi(self)
self.verticalLayout.setContentsMargins(0, 0, 0, 0)
self.setWindowFlag(Qt.FramelessWindowHint)
radius = 10
base = self.rect()
ellipse = QRect(0, 0, 2 * radius , 2 * radius)
base_region = QRegion(base.adjusted(radius, 0, -radius, 0))
base_region |= QRegion(base.adjusted(0, radius, 0, -radius))
base_region |= QRegion(ellipse, QRegion.Ellipse)
ellipse.moveTopRight(base.topRight())
base_region |= QRegion(ellipse, QRegion.Ellipse)
ellipse.moveBottomRight(base.bottomRight())
base_region |= QRegion(ellipse, QRegion.Ellipse)
ellipse.moveBottomLeft(base.bottomLeft())
base_region |= QRegion(ellipse, QRegion.Ellipse)
self.setMask(base_region)
if __name__ == "__main__":
import sys
app = QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())

PySide open a new window, but close immediately

I have a question. Although some questions are similar with mine, but i cat't find how to resolve.
I create a login window, when click 'Confirm' button, hope to load a new window. But now the new window will show and close immediately.The code is below:
# -*- coding: utf-8 -*-

self.ui = login.Ui_Form()
self.ui.setupUi(self)
def show_notepad_clk(self): #This function will trigger a new window
print "Hello world!"
# farm.destroy()
time.sleep(1)
showMemoUI().show()
def exit_login_show(self):
time.sleep(.1)
exit()
# self.destroy()
def create_new_user(self):

Add login.py and moreFrame_Modify.py ,these two files are generated by QT designer.

In your case you have 2 errors:
You should not use time.sleep() in a GUI, in the case of Qt you should use QTimer since time.sleep() freezes the GUI.
A local variable created in a function only exists as long as the function is executed, in your case showMemoUI is shown and instantly eliminated, therefore the new window is not observed. The solution is to make the new window member of the class.
Using the above, the solution code is:
import sys
from PySide import QtCore, QtGui
import login
import moreFrame_modify
class show_login(QtGui.QWidget, login.Ui_Form):
def __init__(self,parent=None):
super(show_login,self).__init__(parent)
self.setupUi(self)
self.showmemoui = showMemoUI()
def show_notepad_clk(self): #This function will trigger a new window
print("Hello world!")
QtCore.QTimer.singleShot(1000, self.showmemoui.show)
def exit_login_show(self):
QtCore.QTimer.singleShot(100, QtGui.QApplication.quit)
def create_new_user(self):
print("Create")
QtGui.QInputDialog.getText(self, 'Input Dialog', 'Enter your name:')
class showMemoUI(QtGui.QWidget, moreFrame_modify.Ui_Form):
def __init__(self, parent=None):
super(showMemoUI,self).__init__(parent)
print("Start show")
self.setupUi(self)
print("Show notepad UI")
if __name__=='__main__':
app = QtGui.QApplication(sys.argv)
farm = show_login()
farm.show()
sys.exit(app.exec_())
