QFrame showing 4 different widgets

[hgedek]

I crated a main widget and It has a QFrame on it.I have 4 widgets .I am trying to show these widgets on this frame.For first widget there is no matter.By using setupUi I can do.But for others I can't.There is no changing.It is still showing first widget.I think, before showing others on frame I should destroy previous widget.But I couldn't achieve this.How can destroy this relationship or setupUi mention.?

You want to show all widgets at the same time, or separately?
All in the same time can easily be done with a central widget with a grid layout that contains the others.

Separately can be done with a QStackedWidget as the central widget.
