Forms or QStackedWidget

[hgedek]

I created forms and calling one from other.I created them in an embedded device.So performance is important.While closing a form I am deleting my pointers.Especially deleting widgetitems taking so long time.Also ram(memory) is important for me.program should be small.Because of this I am deleting all members of a form class when closing.I want to learn If I create all on a stacked widget :
-performance
-ram ?
I havent tried yet.Time is limited.

What kind of answer would you expect from us? Try valgrind (callgrind+massif) and compare results yourself?
