Very good tutorial! However for actually moving between the windows that need to be updated, it would be better to use the insertWidget and removeWidget methods. If you keep adding widgets and incrementing the stack, the old widgets are not deleted and the stack will simply continue to grow and use much more memory than it needs to

Why you don't have subtracted 1 when moving from screen 2 to 1 in index?

This video is helpfull, although I have a question about switching screens. For instance, in this video both of classes are on the same module, right? But in a biggest application, how can I do the switch screen? I have found no way to make swicht screen, which is saved in different modules.

Hi, thank you very much for this guide. Helped me a lot with PySide6.

Here is a working example of my code which removes the current active Widget to free up memory and then adds a new widget.
KEEP IN MIND:
By doing this you will lose the data of the widget which is being removed. Example of if your first widget is a login screen then you do not want to do this because it will remove their login ID data that the user might have entered, he/she will have to enter everything again. In that instance switching the index will do the trick.



def screen2(self):
s2 = screen2()

widget.addWidget(s2)

going back to screen 1:

def screen1(self):
s1 = screen1()

widget.addWidget(s1)

app = QApplication(sys.argv)
widget = QStackedWidget()


s1 = screen1()
widget.addWidget(s1)
widget.setFixedSize(1124, 844)

widget.show()
app.exec()

[timurka]

Thank you very much! I had a problem that I couldn't switch windows with Controller, after some changes it stopped working. Even though I'm Russian, I understood everything perfectly.

Your tutorial is very good, can you do another tutorial to open 2nd window in mdi area, mdi area when clicking file menu action

[someoneontheinternetuvenev]

Hey I have a question, doesn't the 2nd method of creating new instances cause memory leaks?

[anonymousghost]

When ya adding widgets all time whenever ya switch windows the program use more memory
Shouldn't ya remove widget to get back
Am i wrong?

[robpersonalteacher]

You are fantastic!!!! I loved how well you explained everything and the fact that you focus on functionality.

[ayushmaanyadav]

Now I can use this concept to implement tabs feature in my project.(making a web browser btw)

[tommysellbee]

Hi I have a question, how do I handle the closeEvent of the QStackedWidget?
