how to morph a Qdialog into a QMainWindow
-
Being a newbie, I put a lot of effort designing a Ui but unfortunately I started with a Qdialog and now I realize I am better off with a QMainWindow.
I found the post Re below, then edited the ui XML file, substituted QMainWindow for QDialog (it was there only once), but the effect was I lost all my content. When opened in QtDesigner everything is gone. Fortunately I kept a backup copy :)
It seems it works from QMainWindow to QDialog but not the reverse. What can I do?

Hi and welcome to devnet,
You likely have put everything in a layout, right ?
That's the correct thing to do however, QMainWindow already has a layout hence your "losing" stuff impression.What you would need to do is to set a central widget on it and put your layout on that central widget.
