setCentralWidget() without deleting prev widget

Ohh, ok.

Set a QStackedWidget as your central widget, then you can add multiple "central widgets"'.

I need to add one widget to centralWidget, not multiple..
Just I need that setCentralWidget() don't delete previous widget, because I will use this widget later.
QStackedWidget can do this work?

If I were you, I would already have checked the documentation of QStackedWidget

Ok. I'll check the documentation of QStackedWidget, thanks!
