I am not getting promoted widget on the sceen

[Thank You]

It use to work while promoting widgets of StackedWidgets
I can't understand why this is not working

Your parent widget has no layout.

[Thank You]

@Christian-Ehrlicher
Now I got it
It does not have size for the contents of window and
if we put layout to it then it will try to keep content inside it

It is shown in ui file
and because it has no content on given portion so it wont display anything

Thank You
