How to make another window which has the same geometry (position and width, height) as the original window, to simulate that the entire page changed? [duplicate]

I'm just getting started with PyQt5. I have been trying to accomplish a seemingly very simple task but haven't been able to get enough info about it. After a fair bit of googling I have been able to get one window to close and another to launch with the other UI loaded but that's not what I want to do here.
I want to switch the UI in the same window. I am loading the UI files as global variables in my python file where I have 2 classes for each UI. When I click a particular button in one UI, I want to switch to the other UI in the same window. Below is a sample of the code:
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import sys
from PyQt5.uic import loadUiType
import os
about_company_ui, _ = loadUiType(os.path.join('frontend', 'ui', 'about_company.ui'))
intern_placement_ui, _ = loadUiType(os.path.join('frontend', 'ui', 'intern_placement.ui'))
class InternPlacement(QMainWindow, intern_placement_ui):
def __init__(self):
QMainWindow.__init__(self)
self.setupUi(self)
self.intern_pushButton.clicked.connect(self.change)
def change(self):
self.about_company = AboutCompany()
self.about_company.show()
self.close()
class AboutCompany(QMainWindow, about_company_ui):
def __init__(self):
QMainWindow.__init__(self)
self.setupUi(self)
if __name__ == '__main__':
app = QApplication(sys.argv)
window = InternPlacement()
window.show()
app.exec_()

You have to use a QStackedWidget
import os
import sys
from PyQt5 import QtCore, QtGui, QtWidgets, uic
ui_folder = os.path.join("frontend", "ui")
about_company_ui, _ = uic.loadUiType(os.path.join(ui_folder, "about_company.ui"))
intern_placement_ui, _ = uic.loadUiType(os.path.join(ui_folder, "intern_placement.ui"))
class InternPlacement(QtWidgets.QMainWindow, intern_placement_ui):
def __init__(self, parent=None):
super(InternPlacement, self).__init__(parent)
self.setupUi(self)
class AboutCompany(QtWidgets.QMainWindow, about_company_ui):
def __init__(self, parent=None):
super(AboutCompany, self).__init__(parent)
self.setupUi(self)
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
intern_window = InternPlacement()
about_window = AboutCompany()
w = QtWidgets.QStackedWidget()
w.addWidget(intern_window)
w.addWidget(about_window)
intern_window.intern_pushButton.clicked.connect(lambda: w.setCurrentIndex(1))
w.resize(640, 480)
w.show()
sys.exit(app.exec_())

How to display Hello World dialog from TaskBar Menu Application Python/Pyside2 for MacOS

Creating first a dummy "hello world" dialog/window, how to display it from taskbar/menu on MacOS. Thanks.

If I understood your question,
you wanted to open a QDialog from the menu bar of a QMainWindow, right?
For that this is a simple approach:
import sys
from PySide2.QtCore import Slot
from PySide2.QtWidgets import (QApplication, QMainWindow, QAction,
QDialog, QLabel, QHBoxLayout)
class Dialog(QDialog):
def __init__(self):
QDialog.__init__(self)
layout = QHBoxLayout()
layout.addWidget(QLabel("Hello World"))
self.setLayout(layout)
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.menu = self.menuBar()
self.test_menu = self.menu.addMenu("Test")
self.hello_action = QAction("hello", self)
self.hello_action.triggered.connect(self.hello_dialog)
self.test_menu.addAction(self.hello_action)
#Slot()
def hello_dialog(self, checked):
dialog = Dialog()
dialog.exec_()
if __name__ == "__main__":
app = QApplication()
window = MainWindow()
window.show()
sys.exit(app.exec_())

PyQt5 - pythonw.exe crash on handling clicked event

I'm new to PyQt5 and I've got an error (pythonw.exe not working anymore) with the following code:
import sys
from PyQt5.QtWidgets import QWidget, QPushButton, QApplication
from PyQt5.QtCore import QCoreApplication
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
qbtn = QPushButton('Quit', self)
qbtn.clicked.connect(self.q)
qbtn.resize(qbtn.sizeHint())
qbtn.move(50, 50)
self.setGeometry(300, 300, 250, 150)
self.setWindowTitle('Quit button')
self.show()
def q():
print('test')
sys.exit()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
app.exec_()
First it works, but only until I push the "quit" button. Then the error message pops up.
If I put the q() function outside the class (and change "self.q" into "q") it works fine.
What's the problem?
Thanks in advance.
Windows 7
Python 3.4.3 (x86)
PyQt 5.5.1 (x86)

that's because when q() is inside the class it's expects a compulsory argument as the first parameter, this is usually called self and is passed for you implicitly by python when you're calling the method (q() not q(self)). just as you've done with the initUI method in your class, when you put it outside the class, it's just a normal function and not a method again (function in a class), so it's fine to define the function without self
import sys
from PyQt5.QtWidgets import QWidget, QPushButton, QApplication
from PyQt5.QtCore import QCoreApplication
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
qbtn = QPushButton('Quit', self)
qbtn.clicked.connect(self.q)
qbtn.resize(qbtn.sizeHint())
qbtn.move(50, 50)
self.setGeometry(300, 300, 250, 150)
self.setWindowTitle('Quit button')
self.show()
def q(self):
print('test')
sys.exit()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
app.exec_()

Qpixmap image not loading in pyqt4 4.9 python

-EDITED
Im using this code to load a picture in a qlabel found in zetcode. Its working in later version of pyqt4, But not in pyqt4 4.9. Is there a change in using qpixmap in pyqt4 4.9? Thanks.
import sys
from PyQt4 import QtGui, QtCore
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
hbox = QtGui.QHBoxLayout(self)
pixmap = QtGui.QPixmap("redrock.png")
lbl = QtGui.QLabel(self)
lbl.setPixmap(pixmap)
hbox.addWidget(lbl)
self.setLayout(hbox)
self.move(300, 200)
self.setWindowTitle('Red Rock')
self.show()
def main():
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
if __name__ == '__main__':
main()

I am using the same version as you and for this example to work you script must be in the same directory as redrock.png
